What is glatiramer?

Glatiramer is used to treat relapsing forms of multiple sclerosis in adults (including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease).

Glatiramer will not cure MS, but it can make relapses occur less often.

Glatiramer may also be used for purposes not listed in this medication guide.


Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.

Before taking this medicine

You should not use glatiramer if you are allergic to glatiramer or to mannitol.

Tell your doctor if you are pregnant or breastfeeding.

How should I use glatiramer?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Glatiramer can be given using a prefilled syringe or an optional autoinjector. Use the medicine exactly as directed.

Glatiramer is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself. Do not inject into the same place two times in a row. Glatiramer injections are given either daily or 3 times per week, depending on your dose.

Read and carefully follow any Instructions for Use provided with your medicine. Do not use glatiramer if you don't understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.

If you are using an autoinjector, make sure it is the right one. You can get the wrong dose if you use the incorrect autoinjector. Talk to your doctor or pharmacist if you have any questions.

Store the prefilled syringes in the refrigerator. Do not freeze. Throw away any syringe that has been frozen.

Take the medicine out of the refrigerator and let it reach room temperature for 20 minutes before injecting your dose.

If refrigeration is not available, a prefilled syringe will keep for up to 30 days if stored at room temperature. Protect from moisture, light, and high heat.

Throw away a prefilled syringe after one use, even if there is still medicine left inside.

Call your pharmacist if the medicine looks cloudy, has changed colors or has particles in it.

Do not reuse a needle or syringe. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.

What happens if I miss a dose?

Use the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not use two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while using glatiramer?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
