What Happens If You Give a Subcutaneous Injection Intramuscularly?

What happens if you give a subcutaneous injection intramuscularly? Learn to administer self-injections takes practice. Injection sites should be thoroughly cleansed and inspected to prevent infection; additionally, using the right technique is crucial.

Pinching the skin elevates subcutaneous tissue and alleviates discomfort. Quick insertion with an appropriate needle length lowers risk of accidental muscle injection.

Fat Tissue

Insulin injections for diabetes can be given subcutaneously. Placing the injection in fat tissue rather than muscle may slow absorption of medication and impact its effectiveness, in addition to potentially irritating the injection site or even raising small lumps on skin – something not usually an issue with most medications but may become problematic with some slow-releasing ones, like certain blood thinners.

Subcutaneous injections tend to be less painful for some individuals because the needle doesn’t penetrate as deeply into tissue. Still, it is essential to follow any instructions provided by either your pharmacist or doctor on how to prepare and give an intramuscular injection safely.

Subcutaneous injections can be performed on various body areas, including the outer surface of an arm, the upper area of a thigh and two inches below the belly button on an abdomen. When administering injections at these sites it’s wise to change injection sites regularly so as to not become familiar with one spot and overuse it.

Before getting an injection, it can help to use a numbing cream and distract yourself by watching TV, taking deep breaths or having a conversation. Subcutaneous injection pain should only last a few minutes; if discomfort lasts beyond that point, consult with your physician immediately.

Blood Vessels

Subcutaneous injections may damage blood vessels, leading to pain, swelling and bruises at the injection site. Therefore, it is vitally important that injection sites are thoroughly sterilized prior to administering medicine at their respective points on the body at appropriate angles and with suitable needle sizes.

Subcutaneous injections should take place in areas with abundant fat deposits, such as the thigh or abdomen, where needle insertion at 45 degrees from skin surface should result in optimal results.

Erroneous injection can damage nerves and lead to discomfort, numbness and/or tingling at the injection site. Further medical treatment may also be required in order to restore proper nerve function.

Before giving a subcutaneous injection, thoroughly prepare the site by swabbing with a single-use swab and drying it off with paper towels. Pinch or grasp the skin fold at the injection site with your thumb and forefinger (grasper technique), or spread tissue taut using pinch method (pinch method). Be sure that the needle length matches that of the fold width; half should be half. Pull straight off with nondominant hand to reduce risk of accidental needlestick injuries.


Subcutaneous (also referred to as subq or saline) injections are much less painful than intramuscular injections, which involve injecting directly into muscles using long needles. Subcutaneous injections make an ideal option for people needing self-inject at home.

Utilizing the appropriate technique can help make an injection less painful, with some finding relief from using an ice pack or topical numbing cream on their skin to relieve pain. Gaining clarity about what’s happening while giving an injection may also prove useful.

A doctor or pharmacist can show you where and how deep to insert an injection, which may have an impactful influence on how much pain is felt and the type of medicine prescribed.

An injection given at an incorrect angle or depth can result in hematoma, or the collection of blood under the skin, which can be painful. Without proper sterilization measures in place, infection at the injection site may also develop; symptoms include swelling, redness, warmth, tenderness and fever – serious infections require medical intervention immediately if any symptoms emerge; it’s always wise to dispose of needles or syringes in a sharps container rather than regular garbage bins.


Subcutaneous medications are administered subdermally and injected subcutaneously into fat tissue just beneath the skin as an alternative to injecting directly into muscles or veins, which has more severe risks and side effects. A subcutaneous injection usually produces discomfort at its site which usually subsides within 24 hours; other complications could include bruises, fever, or chills which are all indicators of infection requiring medical attention should any symptoms present themselves. It’s important to adhere to proper injection procedures if these issues arise as soon as possible to ensure safe administration.

Administering subcutaneous injections incorrectly may result in severe damage, especially if the needle penetrates a nerve or artery. This could cause painful, tingling and weak muscles around the injection site as well as potential serious muscle or bone damage.

For maximum effectiveness in injection administration, always ensure the area to be injected is thoroughly cleansed with an alcohol swab before injecting. Applying ice beforehand can also make the shot more bearable. When disposing of needles afterward, be sure to use puncture-resistant containers because throwing needles away with regular trash could put those handling it at risk; additionally it’s a good idea to switch up injection sites regularly in order to minimize bruises and pain.
