Does teriflunomide have any side effects?

Donna Hill Howes, RN
Family Practitioner

Teriflunomide stays active in a person's body for several days after it is taken and can stay in the body for up to 2 years. This may cause problems for women who want to get pregnant, because teriflunomide can harm the baby. The drug has also been found in the semen of men who take it. It is not known if this affects babies conceived during treatment. Men who plan to father a child should talk to their doctor about stopping the drug.

Other side effects may include headaches, flu-like symptoms, upper respiratory tract infections, hair loss, abnormal skin sensations, joint pain, nausea, diarrhea, and high blood pressure. Some people have had severe liver injury.
