Table of contents:

Tecfidera (scientifically known as dimethyl fumarate) is a prescription medicine indicated to treat relapsing forms of multiple sclerosis (MS), which includes clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults. Tecfidera is not indicated to cure but can only lessen the episodes of worsening MS.

Tecfidera belongs to the class of medicines called selective immunosuppressants. It works by reducing inflammation and preventing damage to the myelin sheath that protects nerve cells in the brain and spinal cord.

Uses and Dosage

Tecfidera is typically prescribed in capsule form for oral use, usually taken twice a day, with or without food as instructed by a doctor. Taking the drug with food may help alleviate flushing, a potential side effect. Swallow the whole capsule with water, and do not crush or chew it, to avoid the risk of releasing the active ingredients all at once, which can increase the risk of side effects.

The recommended dosage for Tecfidera (dimethyl fumarate) may vary based on the patient and their specific condition. However, the typical starting dose for Tecfidera is 120mg twice per day orally. After one week, the dose should be increased to the maintenance dose of 240mg twice per day orally. Follow your doctor's instructions regarding dosage and timing of medication.

To achieve the best results, take Tecfidera regularly and stick to the dosing schedule prescribed by your doctor. Changing the dosage or frequency of use should only be done under medical supervision to avoid potentially worsening the medical condition being treated.
