Acute teriflunomide overdose with relatively mild symptoms: A case report.

ABSTRACT

WHAT IS KNOW AND OBJECTIVE: Teriflunomide is indicated for the treatment of adult patients with relapsing-remitting multiple sclerosis. CASE SUMMARY: We present a rare intoxication with a high dose (672 mg) of teriflunomide. According to its product label, the only known treatment is the administration of colestyramine and activated carbon (charcoal). No serious adverse events occurred during the time the patient was admitted (<24 h). No long-term overdose-related symptoms or complaints were reported. WHAT IS NEW AND CONCLUSION: The fact that after the acute overdose both adverse events and laboratory parameters were acceptable, prescribing colestyramine and activated carbon, as well as monitoring of laboratory parameters such as full blood count, liver and kidney values and QTc, seems sufficient during the early stage (<24 h after intake) of teriflunomide overdose.
