Subcutaneous (SQ or Sub-Q) injection means the injection is given in the fatty tissue, just under the skin. An SQ injection is the best way to give yourself certain medicines, including:
The best areas on your body to give yourself a SQ injection are:
Your injection site should be healthy, meaning there should be no redness, swelling, scarring, bruising, or other damage to your skin or the tissue below your skin. Change your injection site from one injection to the next, at least 1 inch apart. This will keep your skin healthy and help your body absorb the medicine well. You will need a syringe that has a SQ needle attached to it. These needles are very short and thin.
You may get syringes from the pharmacy that are pre-filled with the correct dose of your medicine. Or you may need to fill your syringe with the correct dose from the medicine vial. Either way, check the medicine label to make sure you are taking the correct medicine and the correct dose. Also check the date on the label to make sure the medicine is not outdated. In addition to a syringe with the medicine, you will need:
The following steps should be followed:
The following steps should be followed when preparing your syringe:
If you are filling your syringe with medicine, you will need to learn the proper technique for filling a syringe with medicine. The following steps should be followed when injecting the medicine:

[PubMed] A subcutaneous injection or shot is one into the fatty tissues just beneath the skin. These injections are shallower than those injected into muscle tissues. Providers often use subcutaneous injections for medications that must be absorbed into the bloodstream slowly and steadily, such as insulin. Subcutaneous injections are usually safe and do not require as much force as intramuscular injections into the muscle tissues. 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. This makes it an ideal way to administer medications that the body must use slowly over time, such as insulin for the treatment of diabetes. Medications given this way include:
Many drugs that must be taken daily, or injected at home, are designed for subcutaneous injection. To give a subcutaneous injection, people should follow these steps:
The best location for a subcutaneous injection depends on a person’s pain sensitivity and where they have some subcutaneous fat. A few commonly chosen locations include:
Some subcutaneous injections come in the form of an auto-injector. An auto-injector is a self-contained device that does not require drawing the medication up first. People can follow the instructions on the package if they are using an auto-injector. Share on PinterestUsing ice to numb the area before the injection may reduce discomfort. The needle used for subcutaneous injection is usually small and short and causes minimal discomfort. The amount of pain a person feels depends on factors such as where they or another person administer the injection, their pain tolerance, and skin sensitivity. The pain also depends on the medication they are injecting, as it may cause stinging, burning, or aching during or following the injection. Subcutaneous injections tend to be less painful than intramuscular injections because the needles are smaller and do not have to push through as much tissue. Children and people who fear needles may still have issues with these injections that can cause anxiety. A few strategies can help with the pain and anxiety:
The most common complication of a subcutaneous injection is pain near the injection site for 1 to 2 days afterward. Pain near the injection site can happen when inserting the needle at the wrong angle, or when it moves slightly during the injection. Some medications can cause a bruise or irritation at the injection site. Other complications are much less frequent and include:
Injecting a blood vessel can cause serious complications in rare cases. However, the likelihood of hitting a blood vessel in the subcutaneous fat is extremely rare. More than likely, if there is blood, it is from slight bleeding after the injection. A subcutaneous injection is a minor and very safe medical procedure when done correctly. Mastering the technique of injecting at home can take some practice. People should ask for help from a medical provider and not shy away from asking questions about the benefits of treatment or how best to minimize pain. |
