Common known side effects

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

The most commonly occurring side effects of glatiramer acetate are redness, pain, inflammation, itching, or a lump at the site of the injection. Some patients have reported a rare reaction that started immediately after the injection and consisted of flushing, chest tightness with racing or pounding heartbeat, anxiety, and difficulty in breathing. The symptoms of this reaction generally lasted approximately fifteen minutes and resolved without any further problems. However, if you inject glatiramer acetate and experience dizziness, hives and itching, sweating, chest pain, difficulty in breathing, or other uncomfortable changes in your general health, call your doctor immediately. If symptoms become severe, or you cannot reach your doctor, call 911 or the appropriate emergency phone number in your area for assistance.
