Tecfidera™ (dimethyl fumarate) is a prescription medication approved to treat relapsing forms of multiple sclerosis (MS) in adults. Tecfidera was known as BG-12 when it was being developed. It is still sometimes referred to by this name.
In relapsing forms of MS, there are distinct periods when symptoms are worse (known as attacks, relapses, or flare-ups). Tecfidera can help reduce the number of attacks a person has; however, it is not a cure for MS.
This drug comes as a capsule that is taken twice daily. Most people tolerate the medicine well. However, side effects are possible and include nausea, diarrhea, and abdominal (stomach) pain.
