Barbiton Phenobarbitone Ponatinib Hydrochloride
ModeratePhenobarbitone can lower the amount of ponatinib in your blood. It does this by making the liver break ponatinib down faster, through an enzyme called CYP3A4. With less ponatinib in the blood, the medicine may not work as well as it should. Tell your doctor if you are taking phenobarbitone, so they can decide how best to manage the two together.
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.
