What are the side effects of glatiramer acetate (Copaxone)?

Glatiramer acetate (brand name Copaxone) is a drug used to treat the relapsing-remitting form of multiple sclerosis (MS). MS causes nerve damage which can lead to weakness, numbness, and loss of bodily control and function. Glatiramer acetate works by modifying the immune system. This leads to a decrease in the number of relapses and the time between relapses. While this drug can provide relief for MS patients, there is no actual cure for multiple sclerosis.

Side effects of glatiramer acetate can include injection-site reactions, chest pain, swelling, nausea, anxiety, flushing, pain, weakness, upset stomach, headache, and yeast infections. Rare but serious side effects may include high blood pressure, swollen lymph nodes, difficult breathing, vision problems, speech problems, or fainting. Be sure to talk to your doctor if your side effects become bothersome or severe.

This list is not all-inclusive, so be sure to talk to your doctor or pharmacist regarding any questions you may have about this medication.
