How does glatiramer acetate (Copaxone or Brabio) work?

It's not clear how glatiramer acetate (Copaxone or Brabio) works. It seems to kill the immune cells that attack the coating (myelin) around nerves in your brain and spinal cord.

You inject it under your skin once a day or, at a higher dose, three times a week.

How well does glatiramer acetate (Copaxone or Brabio) work?

MS drugs can be put into three groups based on how well they control it. The effectiveness of glatiramer acetate (Copaxone or Brabio) is classed as 'moderate', the least effective of the three groups. This is based on how much it reduces relapses and slows down how fast your disability gets worse.

Long term evidence, from people on glatiramer acetate for years, shows its effect is much bigger than 'modest' if you start it early on in your MS.

Relapses dropped by: 34%

This means that in a trial, on average, people saw a 34% drop in the number of relapses they had. This was compared to people who took a placebo, a dummy treatment with no drug in it.

Disability getting worse was slowed down by: a modest amount

This means that in a trial, on average, people saw a modest drop in the risk of their disability getting worse. This was compared to people who took a placebo.

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

Compared to other DMTs the risk of side effects, especially serious ones, is among the lowest. After their injection some people go red in the face (flushing), feel breathless or get a pounding heart for a short time. Most people find that where they inject into their skin it bruises, becomes itchy or goes red or hard. You could also get dents in your skin where you inject.

More than one in 10 people also get one or more of these:

  • headaches
  • rash
  • flu-like symptoms

  • joint or back pain
  • feeling weak or sick.

Glatiramer acetate (Copaxone or Brabio) and pregnancy, breastfeeding and contraception

Pregnancy

There’s no evidence glatiramer acetate harms unborn babies. This drug is available under two brand names: Copaxone and Brabio. There’s been a lot of research into Copaxone and pregnancy but not into Brabio.

You can take Copaxone while you're pregnant if your neurologist thinks you need to. 

If you prefer, you can stop taking this drug up to a month before you try to get pregnant. One month (or less) is the ‘washout period’. That’s how long it takes for levels of the drug in your body to reach a level where it’s totally safe to get pregnant.

If you can become pregnant, ask your neurologist for advice if you want to take either brand of glatiramer acetate. 

If you and your partner want to have a child, discuss this with your neurologist. If you think you’ve become pregnant, let your medical team know at once. Never stop your DMT without first getting their advice.

Breastfeeding 

You can take Copaxone while breastfeeding. If you want to breastfeed, ask your neurologist for advice about feeding this way while taking glatiramer acetate (and for a month after you stop taking it).

Contraception

There are no special recommendations about contraception while taking glatiramer acetate (Copaxone or Brabio).
