Patients who are receiving concomitant anticonvulsant medications primarily metabolized by the liver, such as phenytoin and phenobarbital, may require periodic monitoring of plasma levels [see Drug Interactions (7.5) ] .

Phenytoin Phenobarbital ↓ anticonvulsant ↓ EFV Monitor anticonvulsant plasma levels periodically because of potential for reduction in anticonvulsant and/or EFV plasma levels.

Anticonvulsants: Carbamazepine ↓ carbamazepine The interaction between EFV and the drug was evaluated in a clinical study.

Alternative anticonvulsant treatment should be used.
