Why does monist-at 3 burn and itch?

Monistrol-at is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat pain and inflammation. It is usually taken orally in the form of a pill or tablet. Monistrol-at can cause burning and itching at the injection site when administered as an injection. This is most likely a reaction to the preservatives used in the injection, which can include benzyl alcohol, sodium bisulfite, or disodium edetate. These preservatives are known to cause irritation and inflammation in some people. Additionally, the monistrol-at itself can cause skin reactions in some people, including itching, burning, and rash. If you experience burning or itching at the injection site after using monistrol-at, you should talk to your doctor.
