Injection site reaction


On injecting a drug on the skin, there can be cases of redness or inflammation in the area where the drug was injected. This is called an injection site reaction. It happens because of extravasation that is when drugs escape out of veins after injection. Sometimes it can be a local allergic reaction or flare reaction. A severe reaction and skin damage can be caused by the extravasation of vesicant drugs.

The way of treating injection site swelling depends on the intensity of the reaction. Most of the inflammation after injection is mild. Applying a cold pack reduces pain, swelling, etc. Sometimes the pressure is applied at the site till the bleeding stops. There are also over the counter pain medicines to treat injection site reactions. If fever accompanies then antipyretics can help.

It is advised to move the arm after receiving the injection. Over-the-counter pain relievers help reduce swelling. Applying a warm pack on and taking off the site can help.
