Consequences of Administering a Subcutaneous Injection Incorrectly- What to Expect

What happens if you give a subcutaneous injection wrong?

Administering a subcutaneous injection is a common medical procedure that involves injecting medication into the layer of tissue just beneath the skin. While it is generally a safe and effective method of delivering medication, there are potential risks and complications if the injection is given incorrectly. Understanding the potential consequences can help individuals and healthcare professionals take the necessary precautions to ensure the safe administration of subcutaneous injections.

Incorrect injection site

One of the most common mistakes when giving a subcutaneous injection is selecting the wrong injection site. The recommended sites include the abdomen, thigh, upper arm, or buttocks. If the injection is given in an area that is not suitable, it may not be absorbed properly, leading to ineffective treatment or even tissue damage. For example, injecting into a muscle instead of the subcutaneous tissue can cause muscle irritation or damage.

Incorrect needle angle

Another critical factor in subcutaneous injection technique is the needle angle. The needle should be inserted at a 45 to 90-degree angle to ensure that it reaches the subcutaneous tissue. If the needle is inserted at too shallow an angle, it may not reach the intended layer, and the medication could be injected into the muscle or blood vessels, leading to pain, bruising, or even infection. Conversely, if the needle is inserted at too steep an angle, it may cause tissue damage or blood vessels to be punctured.

Incorrect needle depth

The depth of the needle is also crucial. If the needle is inserted too shallowly, the medication may be absorbed too quickly, leading to a sudden spike in blood levels and potential side effects. On the other hand, if the needle is inserted too deeply, it may reach the muscle or blood vessels, causing pain, bruising, or damage. It is essential to follow the manufacturer’s instructions and the healthcare provider’s guidance to ensure the correct needle depth.

Medication leakage

One of the most serious complications of a subcutaneous injection error is medication leakage. If the medication leaks out of the injection site, it may not be absorbed properly, leading to suboptimal treatment outcomes. In some cases, medication leakage can also cause irritation or inflammation at the injection site, increasing the risk of infection.

Infection

If a subcutaneous injection is administered incorrectly, it can increase the risk of infection. Contaminated needles, improper hand hygiene, or failure to clean the injection site can introduce bacteria into the tissue, leading to redness, swelling, pain, and fever. In severe cases, an infection can spread to the bloodstream, causing sepsis, a life-threatening condition.

Conclusion

In conclusion, what happens if you give a subcutaneous injection wrong can range from mild discomfort and ineffective treatment to severe complications such as infection and tissue damage. It is crucial to follow proper injection techniques, select the correct injection site, and adhere to the recommended needle angle and depth. By taking these precautions, individuals and healthcare professionals can minimize the risks associated with subcutaneous injections and ensure the safe and effective delivery of medication.
