Ponatinib Hydrochloride Ketoconazole
ModerateKetoconazole is a strong CYP3A inhibitor, which means it slows the liver enzyme that breaks down ponatinib. Taken together, ponatinib can stay in your body at higher levels than usual. Your doctor should be careful when prescribing them together and may consider starting ponatinib at a lower dose of 30 mg. Do not change your dose yourself. Tell your doctor about all your medicines, including ketoconazole, before you start ponatinib.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
