Filgotin Filgotinib Maleate Diltiazem Hydrochloride
ModerateYour body breaks down filgotinib mainly with an enzyme called carboxylesterase 2 (CES2). In laboratory tests, diltiazem, along with a few other medicines (fenofibrate, carvedilol and simvastatin), was able to block this enzyme. So diltiazem may change how your body handles filgotinib. These were lab findings, not results from patients. If you take both medicines, tell your doctor or pharmacist.
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.
