Subcutaneous injection can be used to give many types of medications for various medical conditions. There are fewer blood vessels in the fatty layer of connective tissue just beneath the skin than the muscle tissue. Having fewer blood vessels means that medication injected subcutaneously is absorbed more slowly.

What are subcutaneous injections used for?

A subcutaneous injection is administered into the fatty tissue of the subcutaneous tissue, located below the dermis and epidermis. They are commonly used to administer medications, especially those which cannot be administered by mouth as they would not be absorbed from the gastrointestinal tract.

What are the indications for subcutaneous injections?

Indications. Subcutaneous injections are to be used for small volumes of drugs that require slow absorption and long duration of action, such as heparin or insulin.

Which injections are given subcutaneously?

Examples of subcutaneous medications include insulin, opioids, heparin, epinephrine, and allergy medication (Perry et al., 2014). To administer an SC injection, a 25 to 30 gauge, 3/8 in. to 5/8 in. needle is used.

What happens if an intramuscular injection is given subcutaneously?

the drug will be absorbed faster from the intramuscular route because muscular tissue has rich blood supply comapred to subcutaneous tissue. Intramuscular injection will be absorbed faster since muscular system is perused with a lot of blood vessels.

What is the difference between IM and SubQ?

Subcutaneous injections (or SubQ or SC, if you like)

For most folx, this is a more comfortable and less painful method than Intramuscular. ... Because this is a smaller needle than the one used for IM, it might take a little bit longer to fully inject the medication.

Is SubQ faster than IM?

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.

Is insulin subcutaneous?

Insulin may be injected into the subcutaneous tissue of the upper arm and the anterior and lateral aspects of the thigh, buttocks, and abdomen (with the exception of a circle with a 2-inch radius around the navel). Intramuscular injection is not recommended for routine injections.

What are the 3 types of injections?

• Injections, also known as shots, deliver liquid medications, fluids, or nutrients directly into a person's body. ...
• Intramuscular injections. ...
• Intraosseous injections. ...
• Intradermal injections. ...
• Side effects and risks.

Where do you give a subcutaneous injection?

Subcutaneous tissue is all over your body, but the most common areas for subcutaneous injections are:

• the upper outer area of the arm.
• the front and outer sides of the thighs.
• the abdomen, except for a 2 inch area around the navel.
• the upper outer area of the buttocks.
• the upper hip.

Why insulin is given subcutaneously?

The preferred tissue space for insulin injection is the subcutaneous layer, which is the fat layer just below the dermis and above the muscle1; it offers slow, stable and predictable absorption, whatever the fat tissue depth2. Stable and predictable absorption of insulin will support optimal blood glucose control.

What happens if insulin is given intradermally?

Intradermal delivery of insulin is a viable delivery route alternative providing reduced time for insulin absorption with less intra-subject variability and lower glycemic response.

What are the potential complications of subcutaneous injections?

4 Potential Complications of Self-Administered Subcutaneous Injection

• 1.) Pain. The thought of injection is already painful—from blood checkups to surgeries. ...
• 2.) Bruising and Other Skin Irritations. Bruising is said to happen from time to time. ...
• 3.) Skin Infection. ...
• 4.) Tool Glitches.

What is the difference between subcutaneous and intradermal injections?

Subcutaneous injections are administered in the fat layer, underneath the skin. Intramuscular injections are delivered into the muscle. Intradermal injections are delivered into the dermis, or the skin layer underneath the epidermis (which is the upper skin layer).

Do you aspirate for subcutaneous injections?

Don't aspirate after inserting the needle (to prevent tissue damage, hematoma formation, and bruising). The likelihood of injecting into a blood vessel is small. Don't massage the site, which can damage the underlying tissue and cause the medication to be absorbed faster than intended.

What medication is given intradermally?

Intradermal injection provides a local and very little systemic effect. It is commonly used for tuberculin skin testing but can also be used for allergy testing and local anesthetics. To give an intradermal injection, a 25-gauge or smaller needle is inserted just under the epidermis at an angle of approximately 10°.

What is the most common injection?

The most common injection people see outside of a hospital setting is probably an insulin injection for individuals with diabetes. Insulin administration at home is a subcutaneous injection and can be given into any reasonably central areas of subcutaneous fat – the lower abdomen or tops of thighs are usually ideal.

Is Bleeding After IM injection normal?

Light bleeding at the injection site is normal, but a person can use a bandage if necessary.

What type of injections are intramuscular?

Drugs may be given intramuscularly both for prophylactic as well as curative purposes, and the most common medications include[2]:

• Antibiotics- penicillin G benzathine penicillin, streptomycin.
• Biologicals- immunoglobins, vaccines, and toxoids.
• Hormonal agents- testosterone, medroxyprogesterone.

What is the proper way to take insulin?

The insulin needs to go into the fat layer under the skin.

1. Pinch the skin and put the needle in at a 45º angle.
2. If your skin tissues are thicker, you may be able to inject straight up and down (90º angle). ...
3. Push the needle all the way into the skin. ...
4. Leave the syringe in place for 5 seconds after injecting.

Where should you not inject insulin?

DON'T: Inject insulin just anywhere.

Insulin should be injected into the fat just underneath the skin rather than into muscle, which can lead to quicker insulin action and greater risk of low blood sugar. The stomach, thighs, buttocks, and upper arms are common injection sites because of their higher fat content.

When do you administer NPH insulin?

The total daily dose is given as 1 to 2 injections per day, given 30 to 60 minutes before a meal or bedtime. Some patients may initially be given a single daily dose 30 to 60 minutes before breakfast, but 24-hour blood glucose control may not be possible with this regimen.

Can you inject test SubQ?

Subcutaneous Injection of Testosterone Is an Effective and Preferred Alternative to Intramuscular Injection: Demonstration in Female-to-Male Transgender Patients.

How long does it take for a SubQ injection to work?

These injections are given because there is little blood flow to fatty tissue, and the injected medication is generally absorbed more slowly, sometimes over 24 hours. Some medications that can be injected subcutaneously are growth hormone, insulin, epinephrine, and other substances.

WHY is intramuscular better than subcutaneous?

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.
