Glatiramer belongs to a group of medications known as immunomodulators. Immunomodulators modify the way our body’s defense system works. Glatiramer is used to treat the relapsing-remitting form of multiple sclerosis (MS). This medication is also used to delay the onset of MS in people who have experienced a single flare-up of symptoms and have changes that suggest MS in their magnetic resonance imaging (MRI) scans.
MS is a disease that affects the way the nerves in our body work. It is an autoimmune disease (the immune system attacks the body) and cannot be spread from person to person. In MS, damage occurs to the myelin sheath, a protective layer that wraps around a nerve, like insulation around electrical wiring. Normally, this sheath allows electrical messages to be sent down the nerve quickly and efficiently. If this insulation is injured, electrical signals in the central nervous system will not be sent properly. For unknown reasons, in MS, the immune system sees the myelin as foreign and attacks it.
It is thought that glatiramer works by altering the immune system to reduce its harmful effects on the myelin sheath. It does not cure MS, but it may decrease the frequency of relapses and reduce the number of damaged brain areas as seen on MRI scans.

These factors may affect how you should use this medication.
Breathing problems: Glatiramer can cause shortness of breath and difficulty breathing, causing symptoms of lung disease to worsen. If you have chronic obstructive pulmonary disease, asthma, or a history of severe allergic reactions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Cardiovascular effects: This medication may have effects on the heart and circulatory (blood vessels) system. If you have heart disease, high blood pressure, and other diseases of the heart and blood system, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Chronic progressive multiple sclerosis (MS): The safety and effectiveness of using this medication by people with chronic progressive MS have not been established. Currently, glatiramer is only recommended for people with the relapsing-remitting form of MS.
Immunosuppression (weak immune system): Glatiramer can modify the immune response and could interfere with useful immune function. If you have a suppressed or reduced immune system, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Infections: Glatiramer may increase the risk of infections. If you notice any signs of an infection such as fever or chills, severe diarrhea, shortness of breath, prolonged dizziness, headache, stiff neck, weight loss, or listlessness, contact your doctor immediately.

Post-injection reaction: Some people have a rare reaction that starts immediately after the injection and consists of flushing, chest tightness with racing or pounding heartbeat, anxiety, and difficulty breathing. The symptoms of this reaction usually last about 15 minutes and go away without further problems. Nevertheless, if you experience any dizziness, hives and itching, sweating, chest pain, or difficulty breathing, you should contact a doctor right away.
