Drug Interactions With Dimethyl Fumarate
It is uncertain whether any drugs may cause interactions with dimethyl fumarate. However, not all possibilities have been ruled out, so it is important to let your healthcare provider know about all medications, vitamins, and supplements you are taking before starting treatment, as drug interactions may be discovered at a later time.
Dimethyl fumarate (Tecfidera™) is a prescription medication used to treat people with relapsing forms of multiple sclerosis (MS). It can help reduce the number of relapses a person has.
Dimethyl fumarate does not have any known drug interactions at this time. However, it is important to point out that it has not been studied with every other medication. Therefore, interactions with dimethyl fumarate may be discovered in the future.
You should always tell your healthcare provider about all of the medications you are taking. This includes any prescription drugs, nonprescription drugs, vitamins, or supplements. As mentioned, although there are no known dimethyl fumarate drug interactions at this time, it does not mean there won't ever be any.
Dimethyl fumarate has been studied with other multiple sclerosis medications, including interferon beta-1a (Avonex®, Rebif®) and glatiramer (Copaxone®), and did not appear to interact with these medications. In addition, no interactions were found when dimethyl fumarate was given about 30 minutes after aspirin (Ecotrin®, Bayer®, Anacin®).
Dimethyl fumarate is not likely to interact with other medicines. However, you should still make sure your healthcare provider knows about all of the drugs you are taking.
