People who have certain types of multiple sclerosis may benefit from treatment with dimethyl fumarate. This prescription drug is reserved for use in the treatment of relapsing forms of multiple sclerosis. It comes as a capsule that is taken twice daily. The dosage is standard for everyone taking this drug, regardless of your age or weight.
Dimethyl fumarate (Tecfidera™) is a prescription medication approved to treat people with relapsing forms of multiple sclerosis (MS). In relapsing forms of MS, there are distinct periods when symptoms are worse (known as attacks, relapses, or flare-ups). Dimethyl fumarate can help reduce the number of attacks a person has.
Dimethyl fumarate was known as BG-12 when it was being developed. It is still sometimes referred to as BG-12.
