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 in clinical studies for up to 4 years. In these studies, Tecfidera decreased white blood cell counts. Therefore, your doctor may do blood tests before starting treatment and from time to time while you take Tecfidera.
The most common side effects were flushing and stomach problems, which happened mainly at the start of treatment and usually decreased over time.
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. If you experience persistent and/or severe flushing or stomach problems, you should speak with your healthcare provider, who may recommend taking Tecfidera with food which may help. You could have other side effects, so if you have any that bother you or don't go away, talk to your doctor or pharmacist. They may have advice for managing symptoms.
