Nirvana 10 mg Tadalafil Phenytoin
ModerateTadalafil can interact with phenytoin, though the leaflet doesn't say how. It lists phenytoin along with other medicines, including rifampin, carbamazepine, phenobarbital and the HIV protease inhibitors, that may interact with tadalafil.
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.
