Is taking Teriflunomide guaranteed not to relapse?

Teriflunomide (Teriflunomide) is a drug used to treat multiple sclerosis (MS) and belongs to the class of immunomodulators. Multiple sclerosis is an autoimmune disease that mainly affects the central nervous system, causing neuronal damage and inflammation. Teriflunomide reduces the symptoms and disease progression of multiple sclerosis by suppressing immune cell activity and modulating inflammatory responses.

After oral administration of teriflunomide, the median time to reach maximum plasma concentration is 1 to 4 hours after administration, and teriflunomide may remain in the blood for up to 2 years after treatment. If necessary, your doctor may want you to use activated charcoal or cholestyramine to help clear the drug from your body more quickly. Teriflunomide may help control the symptoms of multiple sclerosis but does not cure it. Do not take teriflunomide if you are pregnant or planning to become pregnant. Teriflunomide may harm the fetus. If symptoms such as headache, diarrhea, hair loss, and nausea occur after use, you should inform your doctor promptly.
