What is Tecfidera?

Tecfidera is a prescription medicine used to treat relapsing forms of multiple sclerosis in adults (including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease).

Tecfidera is available as hard gelatin delayed-release capsules in two strengths containing either 120 mg or 240 mg of dimethyl fumarate.

Warnings

Tecfidera may cause a serious viral infection of the brain that can lead to disability or death.

These symptoms may start gradually and get worse quickly.

How should I take Tecfidera

You may take Tecfidera with or without food. Taking the medicine with food may help prevent flushing (sudden warmth, redness, or tingly feeling).

Swallow the capsule whole and do not crush, chew, break, or open it.

While using this medicine, you will need frequent blood tests.

Store this medicine in the original container at room temperature, away from moisture, heat, and light.
