Key points
- Teriflunomide is an immunomodulatory agent that may work by decreasing inflammation and the action of immune cells that can cause nerve damage.
- It may cause serious or life-threatening liver damage, and the risk rises with other medications that affect the liver or with pre-existing liver disease.
- Teriflunomide must not be taken during pregnancy or a planned pregnancy, and effective contraception is required before, during, and for up to 2 years after treatment.
How does Teriflunomide work?
In multiple sclerosis, the immune system attacks the myelin sheath, the protective coating around nerve fibres. The molecule teriflunomide is the active metabolite of leflunomide, a medicine used in other autoimmune conditions, and it may interfere with the immune cells that target this coating. It stays in the body for a long time: without a special elimination procedure, it takes an average of 8 months to clear, though this can extend to 2 years.
