Trileptal (oxcarbazepine), phenytoin, phenobarbital, and St. John’s wort can reduce levels of Tivicay in the blood. These drugs should be avoided while using Tivicay.

Tivicay should be taken two hours before or six hours after taking certain (cation-containing) antacids or laxatives, sucralfate, oral iron supplements, calcium supplements, or buffered medication.

An increased methadone dose may be required in a small number of patients.
