Dose Exchange Program

Lenvima Dose Exchange Program

There may be times that a healthcare provider needs to dose reduce a patient during the course of Lenvima treatment due to adverse reaction before the patient has finished their current supply. Through the Lenvima Dose Exchange Program, eligible patients that require a dose reduction can exchange up to 15 unused doses for the same number of doses at the reduced dose strength at no additional cost.

The program allows patients to exchange unused 20-mg doses for 14-mg doses when a healthcare provider has directed a dose reduction based on the prescribing information.

Complete the Lenvima dose exchange enrollment form and fax it—along with a prescription—to Sonexus at 1.855.246.5192.
