Tecfidera works by decreasing inflammation in the body and reducing the symptoms of MS.

In addition to its use in treating MS, Tecfidera has also been studied for its potential to treat other inflammatory conditions and illnesses. Studies have shown that it may effectively reduce the symptoms of psoriasis, Crohn’s disease, and other inflammatory bowel diseases.


How Does Tecfidera Work?

  • The capsules should be swallowed whole with a full glass of water. 
  • Do not open or chew the capsule. 
  • It is best to take Tecfidera with food to reduce the risk of stomach upset.
  • It is essential to continue taking Tecfidera even if you do not feel any improvement immediately. It may take several months for the medication to show its full effect.
  • Most importantly, take dimethyl fumarate as prescribed or recommended by your doctor. Avoid changing the dosage or stopping the medication without consulting your physician.
