4. Bottom Line

Copaxone is a combination of four amino acids that may be given to treat relapsing forms of multiple sclerosis in adults. It has been shown to significantly reduce the number of relapses but may be associated with injection reactions and transient chest pain. There are two different strengths 20 mg/mL and 40 mg/mL and these have different dosage requirements.

6. Response and effectiveness

7. Interactions

There is currently only one documented medication that interacts with Copaxone, according to the product information.

This medication is natalizumab (Tysabri), which may also be given to treat MS or Crohn's disease. Taking these two medications together can increase the risk of reactivation of the JC virus which may result in progressive multifocal leukoencephalopathy (PML). The risk is higher in those with a weak immune system or who are receiving certain medications.

Results from existing clinical trials do not suggest any other significant interactions between Copaxone and other therapies commonly used in MS patients, including the concurrent use of corticosteroids for up to 28 days.

You should refer to the prescribing information for Copaxone for any updates or newly noted interactions. Copaxone has not been formally evaluated in combination with interferon beta.
