How to give intramuscular injections. How to inject yourself in the buttock: description of technique, recommendations and reviews

Every person in his life has encountered a situation when it is necessary to give an intramuscular injection to himself or his loved ones, since this method of introducing a drug into the body is the simplest and most accessible. However, this procedure is not recommended for those who have not encountered similar situations before and do not know how to give an injection. Therefore, in today’s article we will tell you how to choose the right place for an injection in the buttock so that the help is effective and does not cause complications.

Intramuscular injections are the most effective option delivery of the required dose of medicine. At the same time, if you become familiar with the basics of such procedures, you can carry them out at home without calling a nurse every time.

An injection given in the buttock will ensure uniform distribution of the drug throughout the human body over a short period of time. This is ensured by large quantity muscle fibers and a well-developed circulatory system in them. This eliminates the risk of damage to organs, bones and nerve bundles. An injection is considered ideal if it can be placed in a place where blood vessels and large nerve endings are not located. Therefore, you should first consult with the doctor who prescribed the course of treatment about where it is better to give the injection and how to carry out the procedure if you have to do it yourself.

First of all, it is worth noting that before you decide to inject yourself or someone close to you in the buttock, carefully prepare for the procedure. The list of mandatory manipulations in preparation for the injection includes the following items:

You also need to prepare in advance:

• ampoule with medical drug, prescribed for intramuscular administration;
• a syringe packed in a sealed package;
• sterile medical cotton wool;
• special blade;
• alcohol.

Regarding what is the best “tool” to use for introducing required space medications, then this should be guided by the volume of the solution. Typically, to inject yourself, an adult will need a 3 or 5 ml syringe. Syringes with a large volume (10 ml) are extremely rarely used, since it is undesirable to inject such a volume of the drug at a time into the same place. This is fraught not only with prolonged resorption of the solution, but also with the formation of infiltrates, accompanied by painful sensations.

It is also undesirable for children to receive injections without special preparation. However, if situations arise when you need to inject yourself into the buttock, it is better to use 1 or 2 ml syringes.

The needle should be thin and long. By using it to inject the drug into the buttock, the procedure will not be so painful.

In addition, the length of the needle also determines where it will go. In order not to cause adverse consequences in the form of damaged blood vessels or nerves, it is preferable to use a needle with a length of 4 to 6 cm.

How to find the injection site?

To properly inject into the buttock, you need to know where to inject. To do this, it is necessary for the patient to take a prone position on his stomach. This way, the gluteal muscles will completely relax, and the procedure can be performed almost painlessly. In cases where you need to give yourself an injection, it is better to lie down too. However, many who have performed similar manipulations more than once can do it in a standing position.

When making an injection, it is better to direct the needle to the upper part of the buttock. It is correct to give an injection by injecting the solution into the outer quarter of the muscle. This place is easy to determine if you visually divide the buttock into four parts.

Technology of drug administration intramuscularly

Having correctly determined which place is suitable for injecting the drug into the buttock, you can begin the procedure itself. To do this, as previously mentioned, it is necessary to complete all sterilization measures and place the patient on his stomach (even if you have to inject yourself).

Then you need to remove the syringe and put a needle on it. After this, you should take a cotton swab and, moisten it with medical alcohol, wipe the ampoule with the solution. After a series of these steps, you can open the ampoule using a special blade. You need to draw the solution correctly by lowering the needle into the middle, without touching the walls of the vessel. Having drawn the drug into the syringe, you should lift it up with the needle to release excess air. To do this, you should release a small amount of the solution in a stream until it disappears.

Now you can wipe the buttock, or rather the place that you have determined for inserting the needle, with a cotton swab soaked in alcohol. It is correct to inject when the syringe enters the muscle at a right angle. The drug should be administered slowly, after which you can carefully remove the instrument and wipe the injection site with a cotton swab soaked in an alcohol solution. It is advisable to lightly massage this area.

The same goes for patients who have to inject themselves.

Possible consequences

There are drugs, after the administration of which, even if the procedure was performed correctly, a difficult-to-dissolve “bump” appears. In medicine, it is called “infiltration”, and its occurrence can be avoided. To do this, you need to inject the solution into the muscle tissue as slowly as possible, gently pressing the syringe. It is also recommended that for subsequent injections into the same buttock, choose a place 1.5 cm further from the previous injection.

The speedy absorption of the drug is facilitated by a mesh drawn with iodine on the buttock.

Quite often, adverse consequences occur after improperly performed self-injections. In such situations, symptoms such as fever, redness of the injection site and pain in this area indicate the manifestation of a post-injection abscess. Therefore, at the first signs you should immediately consult a doctor.

It is also not uncommon for cases when sciatic nerve is affected by paralysis if the procedure is performed incorrectly. Therefore, if a sharp pain accompanies the first seconds of introducing the solution into the buttock, it is strongly recommended to stop the action and remove the syringe.

It is also recommended to insert the needle only into relaxed muscles, since pain will disturb the patient during the procedure, and the injection site will still be long time"whining" Therefore, before the procedure for administering drugs intramuscularly to children, they need to be reassured and told about the injections in a gentle manner.

If you learn to perform all the actions correctly and know where to inject, injections will become a “habitual thing” for you, and you will be able to help necessary help in emergency situations, not only for yourself, but also for your loved ones.

In the buttock painlessly and without consequences? This question is of particular interest to those who have been prescribed any medicinal product, but I have neither the strength nor the desire to go to the hospital for its intramuscular injection. It is worth noting that such procedures represent quite a effective methods, which are often used to treat any disease. After all, when injecting into this part of the body, the needle passes first through the skin, then through the subcutaneous tissue, and then enters the muscle. Due to the huge number of muscle fibers in human body syringed medicine instantly spreads throughout all organs. Thanks to this, the patient’s recovery occurs much faster.

Features of the injection

Before giving an injection in the buttock, you should first decide on the injection site of the drug. Ideal option for intramuscular injection is a muscle where there are no large blood vessels or nerves. The most the best site is the upper quarter of the buttock, or rather its outer part. In an adult, this place is located 5-8 centimeters below the crest of the iliac bone. It is quite easy to feel with your hands. This quarter of the buttock has virtually no nerve endings, and it is so massive that the injection becomes almost invisible.

Preparation of the drug

Before giving an injection in the buttock, you must do the following: wash your hands with soap several times, prepare an ampoule with medicine and a syringe, and then thoroughly treat them with an antiseptic. After this, the container with the drug should be carefully shaken, filed down and its tip broken off with a sharp movement. When the medicine is drawn up with a syringe, it should be pointed upward, and then press on the piston and push out any existing air bubbles. Before making an injection in the buttock, the needle in the syringe must be replaced, but only if it was used to pierce the stopper of the container with the drug.

Treatment of the injection site

Not every person knows where to give an injection in the buttock. But we have already talked about this a little higher. Thus, for the procedure itself, the patient should be laid horizontally (however, some specialists prefer to do an intramuscular injection into vertical position patient), and then carefully treat the area of ​​skin where you plan to insert the needle. To do this, they usually use a cotton swab, which should be pre-moistened with alcohol.

How to give intramuscular injections correctly

After the patient is ready and the injection site is well prepared, you should take a syringe (preferably in right hand), while the left one needs to stretch the skin quite strongly, and then position it at a right angle (90 degrees to the buttock) and insert the needle into the muscle about 3/4. It is advisable to infuse the medicine slowly. When the syringe is empty, it must be quickly removed from the muscle tissue, and the injection site must be immediately pressed with a cotton swab containing alcohol. This will stop bleeding if it appears suddenly. In addition, strong pressure and light massaging of the injection site can significantly reduce subsequent pain.

How to give an injection in the thigh is usually necessary for those who have been prescribed a course of intramuscular injections. It is not always convenient to go to the hospital every time to get an injection in a hospital, especially if the patient cannot freely lean on his leg. A person can ask loved ones for help, but only if relatives or friends have the skills for such a procedure.

Features of intramuscular injections

It always makes sense to prescribe injections if the doctor considers it appropriate to use the parenteral form of the drug. Intramuscular injections are sometimes more effective for the following reasons:

1. The drug enters the blood immediately after the injection, bypassing the gastrointestinal tract and liver, so there will be no irritating effect on the mucous membranes of the digestive organs. Many drugs can cause dysbiosis, and the microflora will have to be restored with prebiotics.
2. This route will allow the optimal concentration of the drug to enter the body.
3. Absorption and distribution to tissues occurs instantly.

For some diseases, periodic or constant, throughout life, medication is required, and it is intramuscular. Thus, the following drugs are administered:

• insulin;
• analgesics;
• vitamins;
• antihistamines.

These drugs sometimes need to be delivered to the body as quickly as possible, which is important for normalizing well-being, and sometimes even saving life.

In addition to the muscles, injections are given into a vein and subcutaneously. Injections into the muscles are the most painless.

For reference! The injection is given in the thigh, as there is a very large muscle there, which is convenient for distributing the medicine.

Preparation for the procedure

For the entire procedure, in addition to the ampoules themselves, you need to purchase the following medical products:

1. Three-component syringes, one for each injection of the course, even with a reserve.
2. Sterile cotton wool.
3. Medical alcohol
4. Medical tray or saucer.

When purchasing a syringe, you need to pay attention to the needle; its thickness will depend on the amount of fat and the thickness of the skin. For children they take the thinnest one, for obese people the thickest one.

For reference! When purchasing a syringe, you need to choose a volume larger than the required dose by 1 ml.

Regardless of who will receive an intramuscular injection into the thigh, you must first fill the syringe with the drug correctly.

The syringe must be filled immediately before giving the injection. And it happens this way:

1. Take the ampoule with clean hands and wipe the tip with alcohol.
2. Before injecting the drug, you need to make sure that it has the required consistency and does not have foreign impurities and precipitation, for this the ampoule is shaken in the light.
3. The tip is broken off and the drug is injected with a syringe.
4. The syringe is placed vertically; you need to tap it with your fingernail so that all the air floats to the top.
5. All air is released from the syringe by pressing the plunger.

The syringe is ready for injection. Additionally, for each procedure, two cotton swabs are prepared, which are soaked in alcohol.

It is important to ensure sterility every time a procedure is performed. To do this at home, just wash your hands, treat them with an antiseptic and wipe the injection site with an alcohol-soaked cotton pad.

How to inject yourself in the thigh?

Intramuscular injections can be given in the thigh, buttock, abdomen and shoulder. It is more convenient to inject yourself in the thigh. This can and is even better done while sitting.

Not everyone has the courage to inject themselves in the thigh. But once you decide, you can avoid many problems. There will be no dependence on the time of another person capable of doing this. You can do this at any time, and if you pack a travel suitcase with tools for injections, then anywhere. After all, for this there is no need to undress completely.

Important! When inserting the needle, you need to control the depth so that the tip does not dig into the bone. There were cases where the tip of the needle broke on the bone and remained inside.

The technique itself is simple, main secret is to relax the muscles and do the procedure with a confident hand. In order to relax, you can watch the video and understand that it is not scary.

If you show composure at least once, the next injections will go as planned. If you have the necessary equipment and an already filled syringe, the procedure is as follows:

1. You need to sit on a chair in front of a mirror without straightening your legs. The outer part of the thigh, in particular that part of the muscle that does not touch the chair and “hangs” from it, will be the area in which the injection should be given.
2. Fill the syringe correctly with the medicine and with a sharp, confident movement, holding the syringe at an angle of 90°, insert the needle into the muscle.
3. Introduce the medicine slowly, without rushing, to avoid hematoma.
4. At the same 90° angle, remove the needle, pressing it with a cotton swab soaked in alcohol.
5. Throw away the syringe.

It’s good to massage the area a little so that the medicine is absorbed evenly. The thigh is the most comfortable spot for injections, even during military field conditions it is customary to inject yourself into this area.

How to give an injection in the thigh of another person?

It is much more convenient to inject someone in the buttocks. Since the person lies relaxed and it is easier to find the zone. But if, for some reason, it is necessary to do it specifically in the thigh, the course of action will be as follows:

1. The patient should be placed on a comfortable couch and asked to relax.
2. Find a zone. This is the middle third of the anterolateral surface of the thigh.
3. Treat the surface of the skin in the area of ​​the intended injection with an antiseptic.
4. Holding the syringe like a pencil, insert it under the skin with a confident movement.
5. Slowly inject the drug and, holding the puncture site with a cotton pad, remove the needle.

It is important to inject the drug into the muscle to make sure that the needle does not accidentally enter a vein or vessel; you need to slightly pull the piston towards yourself; if the needle is in a vein, it will capture a lot of blood.

Advice! If the injection is too painful, you can add Lidocaine or Novocaine to the medicine.

If a person does not have a thick layer subcutaneous fat, for example, if he is thin or is a child, then before the injection you need to take the area of ​​skin into which you plan to inject the drug into a fold.

Negative consequences of incorrect injection technique

If not correct technique When performing an injection into the thigh and failure to comply with sterility rules, some unpleasant consequences may occur:

• hematoma;
• seals;
• muscle pain;
• abscess.

If lumps form, the drug was most likely injected into adipose tissue. A small hematoma of about 5 mm, which does not bother the person, is acceptable. This means that a small vessel is affected. But if a large one is affected, then the hematoma can be large, and it will take a long time to resolve

To avoid this, it is important to follow the following rules:

1. Do not give injections in a row in the same thigh; they must be alternated.
2. Introduce the medicine slowly.
3. Use a high-quality syringe, with a thin needle and a piston made of high-quality black rubber.
4. Make sure there is no air in the syringe by waiting for a stream to appear.
5. Relax the muscle as much as possible.
6. After administering the medicine, massage this area so that the medicine spreads throughout the muscle and does not leave an infiltrate at the injection site.
7. Choose an injection site that is free of skin lesions and acne.

If all these rules are followed and the correct technique is used, Negative consequences practically excluded.

But if your leg hurts after an injection, this does not always mean that it was done incorrectly. The cause may be too thin blood vessels or poor blood clotting. After some medications, it may hurt, regardless of the administration method. For example, Actovegin and Magnesia.

To make sure that an infection has not been introduced, you should periodically pay attention to the injection area. In case of inflammation, the following signs will appear:

• the leg will become hot to the touch;
• redness appears;
• pain will be felt on palpation;
• swelling forms.

In this case, you should immediately consult a doctor, he will prescribe adequate treatment.

In this article we will tell you in detail how to give an injection correctly to someone or yourself. Quite often, as part of the treatment, medications are prescribed in the form of injections or, simply put, injections. Of course, it is preferable for them to be done by a doctor. But there are situations when the nearest clinic is not open, or you and your family do not have the opportunity to go there every day for injections.

In this case, the ability to give injections at home is a real salvation. At home, you can give intramuscular injections yourself or inject the drug under the skin. Both methods can and should be learned in order to provide timely help to both yourself and a loved one if necessary.

How to give injections correctly

Intramuscular injections are done in the area where some of the largest muscles of the body are located - this is the gluteal muscle, the outer thigh or the deltoid muscle.

If you do subcutaneous injection, then places with a good subcutaneous layer of fat are selected - the abdominal area is suitable for this purpose or inner side hips. It is convenient to give injections in these places and independently - for yourself.

Injections in the buttock or thigh area are made in such a way that the injection area is not repeated. That is, you cannot prick in the same place - it is both painful and fraught with the appearance of bruises or hardening.

Experts recommend choosing a two-cc syringe with a thin needle for injections - it is more convenient to administer the drug and does not leave any seals. Of course, such a choice is possible if there are no special regulations doctor In this case, you must follow the specific recommendations issued.

When administering an intramuscular injection, keep the needle vertical to the surface of the skin, with a slight inclination. And with subcutaneous application - at an angle of 45 degrees.

Always carefully read the instructions for the injected drug - because some of them require additional components for injection. For example, lidocaine or a special aqueous solution.

Also, before each injection, you must wash your hands to prevent the possibility of foreign microorganisms getting into the wound. Despite the fact that the injection site is always treated with alcohol, this is not enough to ensure the necessary sterility.

Watch this video on how to properly give an intramuscular injection.

How to give injections in the buttock at home

Many drugs, including antibiotics, are prescribed by injection - intramuscularly. The course of such injections may have different terms, and very often a situation arises when the injection must be given either early in the morning or late in the evening. At this time, the nearest clinic is no longer open, so it is very important to be able to give intramuscular or subcutaneous injections yourself.

Intramuscular injections are most often given in the buttock - this is one of the largest muscles in our body. There are also no nerve ganglia or large vessels in this area. It is recommended to do the injection while lying down - so that the muscles relax. This not only reduces the pain of the process, but also prevents the risk of accidentally breaking the needle.

Before you start administering the drug, you must make sure that the medicine has a valid expiration date. Also wash your hands with soap or use an antiseptic solution.

Shake the ampoule, tap its top with your fingernail so that all the liquid is at the bottom. The ampoule cap is filed with a special file and the tip is broken off. The medicine is drawn into the syringe with the needle up, after which the syringe plunger is slowly pressed to push the air out of the needle. A sign of success in this case will be droplets of the drug at the tip of the syringe.

The injection is given in the upper part of the buttock, after first palpating the area for the presence of lumps. Next, you need to fix the skin at the injection site with two fingers - the thumb and forefinger.

The injection itself is done as follows:

1. The syringe is held with all fingers at once - vertically, with a slight inclination relative to the surface of the buttock. In one movement, the needle must be inserted to ¾ of its length - approximately 1 cm should remain on the surface.
2. With one hand, hold the syringe in a stationary position, and with the thumb of the other hand, slowly press the plunger - while the drug is injected gradually. This is necessary in order to eliminate pain and the appearance of a lump at the injection site.
3. After administering the drug, you need to press the alcohol-containing cotton wool to the point where the needle enters the skin and pull it out in one motion. The cotton wool is left at the injection site for some time for disinfection.

It is important to rub the injection site so that the drug spreads better throughout the body, as well as to avoid stagnation. Very often, patients complain of bruising or hardening at the injection site. To prevent such phenomena, you need to rub the injection area with light massage movements.

How to inject yourself in the buttock

This useful skill will be useful to everyone, because it is not always possible to go to a clinic or use the services of a qualified nurse who would come to your home.

Despite the apparent complexity, the principle of action is the same as when you inject another person. The only difference is what you need to pay Special attention preparation for the injection.

To give yourself an injection into gluteal muscle, you need to stand in front of the mirror so that you can clearly see your buttock.

Then you need to transfer the body weight from one leg to the other according to the following principle - if you, for example, give an injection in the left buttock, then the body weight should be transferred to the right leg.

In this case, the left buttock will remain relaxed - which is necessary for the injection. Further actions are similar to those when administering an injection for another person.

Insert the needle in one movement so that approximately 1 cm remains on the surface - this is necessary in case the needle suddenly breaks. But, according to doctors, such cases are rare. This is possible in the event of a sharp contraction of the muscle when it becomes tense.

How to give yourself an injection in the thigh

The femoral muscle is also well suited for drug administration. This intramuscular injection option may be more convenient if you are unable to inject yourself in the buttock. And both methods differ, again, in the way they prepare the site for the future injection.

This injection is given while sitting on a chair, with the leg bent at the knee. The part suitable for the injection will be the one that hangs slightly from the chair when bent - this is the anterior lateral part of the femoral muscle. Further actions- the same as with intramuscular injections into the gluteal muscle.

Try to relax your leg as much as possible, do not strain the muscle.

How to give a subcutaneous injection

If you think that it is impossible to give subcutaneous injections at home, then you are mistaken. The basic principle is the same as with intramuscular injections. But there are some differences:

• the skin at the injection site should be slightly folded;
• the needle must be inserted at an angle of 45 degrees - that is, exactly at thin layer skin, and not deep inside - unlike an intramuscular injection, in this case the needle is inserted in one movement, but slowly.

The advantage of subcutaneous injections is that they are less painful than intramuscular ones.

There is nothing complicated in these actions, but there is only one limitation - rather psychological. This is the fear of piercing your own body with a needle in your own hands. Therefore, the main thing is to overcome this barrier.

It happens that you need to get an injection, but there is no doctor nearby. And you have to turn to relatives and those who are nearby. There are craftsmen who can give injections to themselves, but this is not very good idea, if only because it is inconvenient. It is better to give instructions to a person who is ready to help with the procedure.

Step 1: Prepare everything you need

Soap. Not necessarily antibacterial.

Towel. It should be clean, or better yet, disposable.

Plate. You will need to put all the tools on it. At home it is difficult to disinfect the table surface, for example, so you have to work from a plate. It must be washed with soap and wiped with an antiseptic - an alcohol wipe or cotton wool with alcohol or chlorhexidine.

Gloves. At home, gloves are often neglected, but in vain. Since there is no question of any sterility here, gloves are especially needed to protect both the patient and the person giving the injection from the transmission of infections.

Syringes. The volume of the syringe must correspond to the volume of the medicine. If the medicine needs to be diluted, then keep in mind that it is better to take a larger syringe.

Needles. They will be needed if the medicine needs to be diluted. For example, if a dry drug is sold in an ampoule with a rubber cap, then it is diluted as follows:

1. The solvent is drawn into the syringe.
2. The rubber cap is pierced with a needle and the solvent is released into the ampoule.
3. Shake the ampoule without removing the needle to dissolve the medicine.
4. Draw the solution back into the syringe.

After this, the needle must be changed, because the one that has already pierced the rubber cap is not suitable for an injection: it is not sharp enough.

Antiseptic or alcohol wipes. You need 70% alcohol, an antiseptic based on it, or chlorhexidine. For home use, it is best to use disposable alcohol wipes, which are sold at any pharmacy.

Place for trash. You will have to put waste material somewhere: packaging, lids, napkins. It’s better to immediately throw them into a separate box, basket, or wherever is convenient for you, so that it all doesn’t end up on a plate with clean tools.

Step 2: Learn to wash your hands

You will have to wash your hands three times: before collecting the instruments, before the injection and after the procedure. If it seems like a lot, it does.

Lifehacker wrote about how to properly wash your hands. This one has all the basic moves, but add a couple more to them: lather each finger on both hands and your wrists separately.

Step 3: Prepare the area

Choose a convenient place so that you can place a plate with tools and easily reach it. Another mandatory attribute is good lighting.

It does not matter how the person receiving the injection is positioned. He can stand or lie down, whichever is more comfortable for him. But the one who injects should also be comfortable so that his hands do not shake and he does not have to jerk the needle during the injection. So choose a position that suits everyone.

If you are afraid of injecting in the wrong place, before the procedure, draw a hefty cross directly on your buttock.

First, draw a vertical line in the middle of the buttock, then a horizontal one. Upper outside corner- the place where you can prick. If you're still scared, draw a circle in this corner. For artistic painting at least an old one will do lipstick or a cosmetic pencil, just make sure that particles of these products do not get on the injection site.

While the patient lies and is afraid, we begin the procedure.

Step 4: Do everything in order

1. Wash your hands and plate.
2. Treat your hands and plate with antiseptic. Throw away the cotton wool or napkin immediately after processing.
3. Open five alcohol wipes or make as many cotton balls with antiseptic. Place them on a plate.
4. Take out the medicine ampoule and syringe, but do not open them yet.
5. Wash your hands.
6. Put on gloves and treat them with antiseptic.
7. Take the ampoule with the medicine, treat it with an antiseptic and open it. Place the ampoule on a plate.
8. Open the package with the syringe.
9. Open the needle and draw the medicine into the syringe.
10. Turn the syringe with the needle up and release the air.
11. Treat the patient's buttock with an alcohol or antiseptic wipe. First - a large area. Then take another napkin and wipe the place where you will inject. Movements for processing - from the center to the periphery or from bottom to top, in one direction.
12. Take the syringe in a way that is convenient for you. The needle should be perpendicular to the skin. Insert the needle in one motion. There is no need to push it all the way so as not to break it: 0.5–1 cm should remain outside.
13. Administer the medicine. Take your time, make sure that the syringe and needle do not dangle or twitch. You can hold the syringe with one hand and press the plunger with the other.
14. Take the last alcohol wipe or cotton wool, place it next to the injection site and in one motion, pull out the needle to quickly apply pressure to the wound.
15. Don't rub anything with the napkin, just press and hold.
16. Throw away used tools.
17. Wash your hands.

If the injection is painful, inject the medicine slowly. It seems that the faster, the sooner a person will be exhausted, but in fact, a slow introduction is more comfortable. average speed- 1 ml in 10 seconds.

Don’t be afraid to treat the ampoule, hands or skin with an antiseptic once again. Here it is better to overwork than to underwork.

If you need to change needles after drawing up medication, do not remove the cap from the new one until you install it on the syringe. Otherwise, you can inject yourself. For the same reason, never try to cap a needle if you have already removed it.

If you don't know how hard to stick a needle, practice at least chicken fillet. Just to understand that it's not scary.

When to give an injection without specialists

1. If the drug was not prescribed by a doctor. In general, there is no need to engage in self-medication, much less injections, even if for some reason you want to “inject some vitamins.” The drug, its dosage, how to dilute it - all this is determined by the doctor, and only he.
2. If the patient has never taken this drug before. Many drugs have side effects and may cause unwanted reactions. Medicines that are administered through injections enter the bloodstream faster, so reactions to them appear quickly and strongly. Therefore, it is better to give the first injection in medical institution and don’t rush to run away from there, but wait 5-10 minutes so that everything is in order. If something goes wrong, the clinic will help, but at home you may not be able to cope.
3. When you have the opportunity to use the services of doctors, but don’t want to. An intramuscular injection is short-lived and inexpensive, but doing it at home may end up ending, so you won’t be able to save either money or time.
4. When the person requiring the shot has HIV, hepatitis or other blood-borne infections, or if it is not known whether the person has these infections (no valid certificate). In this case, it is better to entrust the matter to specialists in order to eliminate the risk of infection: doctors have more experience, and they will then dispose of the instruments properly.
5. If you are very scared and your hands are shaking so much that you do not hit the patient.
