They tend to avoid using these muscles now because of the potential risk of injury to the sciatic nerve. A healthcare professional should provide people with training and education before asking them to administer intramuscular injections to themselves or another person.

Wash the hands thoroughly with soap and warm water. Pay careful attention to the area between the fingers and under the fingernails. A doctor should provide advice on the type of needle to use. It needs to be long enough to reach deep into the muscle tissue. It is essential to ask a doctor or pharmacist which size needle to use before giving an injection. Locate the injection site according to the instructions above. Gently spread the skin between two fingers and keep the muscles relaxed.

Clean the skin with the alcohol swab and allow to air-dry. If using a multidose vial, note the date you first opened it. Clean the rubber stopper with an alcohol swab. Remove the cap from the syringe. Draw air into the syringe by pulling back the plunger. Fill the syringe with air up to the same level as the medication dose.

Remove the cap from the needle and push it through the top of the vial. Inject all the air into the vial. Turn the vial and syringe upside down so that the needle points upward. Draw back the plunger to fill the syringe with the correct amount of medication.

Remove air bubbles by gently tapping the syringe and pressing the plunger. Avoid touching the needle to ensure it stays clean. Insert the needle into the muscle at a degree angle.

Use the index finger and thumb to stabilize the syringe while using the other hand to pull back on the plunger slightly to look for blood. If there is blood, it means the needle is in a blood vessel and not a muscle. An intramuscular injection is a technique used to deliver a medication deep into the muscles. This allows the medication to be absorbed into the bloodstream quickly.

In some cases, a person may also self-administer an intramuscular injection. For example, certain drugs that treat multiple sclerosis or rheumatoid arthritis may require self-injection. Intramuscular injections are a common practice in modern medicine. Several drugs and almost all injectable vaccines are delivered this way. These include:.

It may be used instead of oral delivery because some drugs are destroyed by the digestive system when a drug is swallowed. Intramuscular injections are absorbed faster than subcutaneous injections. This is because muscle tissue has a greater blood supply than the tissue just under the skin. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.

The deltoid muscle is the site most typically used for vaccines. However, this site is not common for self-injection, because its small muscle mass limits the volume of medication that can be injected — typically no more than 1 milliliter.

A caregiver, friend, or family member can assist with injections into this muscle. The correct area to give the injection is two finger widths below the acromion process.

At the bottom of the two fingers, will be an upside-down triangle. Give the injection in the center of the triangle. Divide the upper thigh into three equal parts. Locate the middle of these three sections. The injection should go into the outer top portion of this section.

The ventrogluteal muscle is the safest site for adults and children older than 7 months. This site is difficult for self-injection, and may require the help of a friend, family member, or caregiver. Place the heel of your hand on the hip of the person receiving the injection, with the fingers pointing towards their head.

Position the fingers so the thumb points toward the groin and you feel the pelvis under your pinky finger. Spread your index and middle fingers in a slight V shape, and inject the needle into the middle of that V. The dorsogluteal muscle of the buttocks was the site most commonly selected by healthcare providers for many years.

However, due to the potential for injury to the sciatic nerve , the ventrogluteal is most often used now. This site is difficult to use this site for self-injection and not recommended. Any person who administers intramuscular injections should receive training and education on proper injection technique. The needle size and injection site will depend on many factors. These include the age and size of the person receiving the medication, and the volume and type of medication.

Your doctor or pharmacist will give you specific guidelines about which needle and syringe are appropriate to administer your medication. The needle should be long enough to reach the muscle without penetrating the nerves and blood vessels underneath.
