Tykerb Drug Interactions

When medicines such as nefazodone or pioglitazone are taken with Tykerb, drug interactions may occur. If these interactions develop, your risk of developing side effects is increased and the level of Tykerb in your blood may be increased or decreased. Other medicines that can cause drug interactions with Tykerb include rifamycin antibiotics, anthracycline chemotherapy medications, and certain seizure medications.
