Lacosamide, a medication used to treat epilepsy and seizures, may interact with other medications, potentially causing adverse effects or altering its efficacy (1). According to the FDA, lacosamide has been evaluated for potential interactions with commonly used medications.
One of the significant interactions of lacosamide is with oral contraceptives. Concomitant use of lacosamide and oral contraceptives may decrease the contraceptive efficacy, thus requiring patients to use alternative or additional methods of contraception (2).
Additionally, lacosamide may interact with other anti-epileptic drugs (AEDs), including carbamazepine, phenobarbital, phenytoin, and valproate. These combinations may increase the risk of adverse effects, such as dizziness, ataxia, or sedation (3).
Moreover, lacosamide may induce the metabolism of other drugs, such as theophylline, and the concomitant use of theophylline and lacosamide may require adjustments in theophylline dosage (4).
To minimize potential interactions and ensure safe co-administration of lacosamide and other medications, patients should consult their healthcare providers and discuss their complete medication history.
