Copaxone is meant to be used as a long-term treatment. In general, you can keep taking it for as long as it continues to be safe and effective for you.
But if you develop bothersome or severe side effects, or the drug doesn’t control your condition well enough, you might need to switch to a different treatment. In that case, your doctor will recommend an alternative treatment for you.
If you have questions about how long you should take Copaxone, talk with your doctor.
