For the Consumer

Applies to teriflunomide: oral tablet


Oral route (Tablet)

Severe liver injury, including fatal liver failure, has been reported in patients receiving leflunomide, and a similar risk is expected with teriflunomide. Teriflunomide use is contraindicated in patients with severe hepatic impairment. Concomitant use with other hepatotoxic drugs may increase the risk of liver injury. Monitoring is recommended and discontinuation of therapy, including an accelerated elimination procedure, is advised if liver injury is suspected. Teriflunomide may cause major birth defects if used during pregnancy. Pregnancy must be excluded before starting treatment with teriflunomide. Teriflunomide is contraindicated in pregnant women or women of childbearing potential who are not using reliable contraception. Pregnancy must be avoided during teriflunomide treatment or prior to the completion of the drug elimination procedure after treatment; advise women to use reliable contraception. Discontinue teriflunomide and use an accelerated drug elimination procedure if pregnancy occurs.

Along with its needed effects, teriflunomide (the active ingredient contained in Aubagio) may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
