Tecfidera side effects
Treatment for relapsing multiple sclerosis (MS) means staying on therapy for as long as you and your doctor decide it's right for you. As a result, many people are rightfully concerned about the side effects of any given treatment. The side effects of Tecfidera have been documented for up to 4 years. Tecfidera may cause serious side effects including allergic reactions, PML (a rare brain infection that usually leads to death or severe disability) and decreases in white blood cell counts. Therefore, your doctor should do blood tests before starting treatment and while you take Tecfidera.
Tecfidera may cause allergic reactions.
Do not use Tecfidera if you have had an allergic reaction (such as welts, hives, swelling of the face, lips, mouth or tongue, or difficulty breathing) to Tecfidera or any of its ingredients.
You should always talk to your doctor before taking Tecfidera if you're pregnant, interested in becoming pregnant, breastfeeding or plan to breastfeed. That's because it isn't known how taking Tecfidera would affect an unborn baby or if it passes into your breast milk. If you're pregnant while taking Tecfidera, talk to your doctor about enrolling in the Tecfidera Pregnancy Registry to monitor your health and the health of your baby.

Common side effects
The most common side effects of Tecfidera in clinical studies were flushing and stomach problems. People tended to have symptoms at the start of treatment, and they usually decreased over time. Talk to your doctor about taking Tecfidera with food or aspirin as it may help with flushing. If you are experiencing stomach problems ask your doctor or pharmacist if they have suggestions to help.
