Highlights for glatiramer

Injectable Solution
1

Glatiramer acetate is an injected medication used to treat forms of multiple sclerosis in which symptoms flare-up and then go away.

2

It isn’t fully clear how glatiramer acetate works in treating multiple sclerosis. It’s believed that the drug may help to prevent your immune system from attacking the nerves in your brain and spine.

3

You may experience some serious reactions after injection. These may include redness to your cheeks, chest pain, anxiety, fast heartbeat, problems breathing, or skin reactions. Chest pain usually only lasts a short time. Call your doctor right away if you experience any of these symptoms.

4

Common side effects include injection site reactions (redness, swelling, pain, or itching), flushing, rash, and trouble breathing.

IMPORTANT INFORMATION

May cause allergic reaction

Call your doctor right away if you experience:

  • redness to your cheeks (flushing)
  • chest pain
  • anxiety
  • fast heartbeat
  • trouble breathing
  • skin reactions, such as rash, itching, hives, or swelling

Chest pain after injection

While chest pain may occur as part of a post-injection reaction, it can also occur by itself around 1 month after you start using the drug. It usually lasts a few minutes. Call your doctor right away if you experience chest pain.

May cause lipoatrophy

This drug may cause damage to the layer of fat underneath your skin (lipoatrophy). In rare cases, glatiramer acetate can cause the skin around the injection site to die (necrosis). You can decrease the chance of this happening by injecting the drug in a different area each time. Appropriate injection areas include:

  • stomach area around the belly button
  • back of the upper arms
  • upper hips below the waist
  • thighs

Drug Features

Glatiramer acetate is a prescription drug. It’s available as a subcutaneous (under the skin) self injection.

How It Works

It isn’t fully clear how glatiramer acetate works to treat multiple sclerosis. It may help to prevent your immune system from attacking the nerves in your brain and spine.

glatiramer May Interact with Other Medications

Injectable Solution

Drug interactions between glatiramer acetate and others drugs haven’t been fully studied. Commonly used drugs to treat multiple sclerosis don’t appear to have important interactions.

Note: You can reduce your chances of drug interactions by having all of your prescriptions filled at the same pharmacy. That way, a pharmacist can check for possible drug interactions.

Disclaimer: Our goal is to provide you with the most relevant and current information. However, because drugs interact differently in each person, we cannot guarantee that this information includes all possible interactions. This information is not a substitute for medical advice. Always speak with your healthcare provider about possible interactions with all prescription drugs, vitamins, herbs and supplements, and over-the-counter drugs that you are taking.

Pregnant women

Glatiramer acetate is a pregnancy category B drug. That means two things: 

  1. Studies of the drug in pregnant animals have not shown risk to the fetus.
  2. There aren’t enough studies done in pregnant women to show if the drug poses a risk to the fetus.

Speak with your doctor if you’re pregnant or plan to become pregnant. Glatiramer acetate should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus.

Women who are nursing

It isn’t known if glatiramer acetate passes through breast milk. Infants exposed to glatiramer acetate in breast milk could experience side effects including rash, trouble breathing, or redness to their cheeks (flushing). You and your doctor should decide whether you should take glatiramer acetate if you plan to breastfeed.

Allergies

Don’t take this drug again if you’ve ever had an allergic reaction to glatiramer acetate or mannitol. Taking it a second time after an allergic reaction could be fatal.

Symptoms of allergic reaction may include:

  • trouble breathing
  • swelling of your throat or tongue
  • hives

Pharmacist's Advice
Healthline Pharmacist Editorial Team

Glatiramer acetate comes with risks if you don’t take it as prescribed by your doctor.

If You Don’t Take it on Schedule

It’s important to take your doses at the times you were told to take them. This keeps the same amount of the drug in your system from day to day to get the most effective results. Missing doses or not taking it as scheduled can change the amount of the drug in your body from day to day and reduce the drug’s effectiveness.

If You Don’t Take It at All

Multiple sclerosis is active in your body and can damage your nervous system, even when you don’t have symptoms. If you don’t take your medication, the damage to your nervous system could get worse.

If You Stop Taking It

Taking glatiramer acetate helps to slow the damage that multiple sclerosis does to your nervous system. Stopping the drug allows the damage to happen more quickly.

What To Do if You Miss a Dose

If you miss a dose, take it as soon as you remember. If it’s close to the time of your next dose, don’t inject the missed dose. Skip the missed dose and resume the regular dosing schedule. Don’t double your dose.

How Can I Tell if the Drug Is Working?

You may be able to tell that glatiramer acetate is working if you notice a decrease in flare-ups.

Glatiramer acetate is a long-term drug treatment.
