Ponatinib Hydrochloride Saquinavir
ModerateSaquinavir can raise the level of Ponatinib in your body. It does this by slowing down the liver enzyme (CYP3A) that normally breaks Ponatinib down. Saquinavir is one of several strong medicines of this kind. Others include clarithromycin, ritonavir, ketoconazole and voriconazole, and grapefruit juice has the same effect. So take extra care if you use these two together. Your doctor may want to lower the starting dose of Ponatinib to 30 mg. Do not change the dose on your own. Let your doctor decide.
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.
