Feldena-10 Tadalafil Ketoconazole
ModerateTadalafil may interact with ketoconazole. The leaflet lists ketoconazole among the medicines that interact with tadalafil, ritonavir and other HIV protease inhibitors being named alongside it, but it does not say what the interaction does.
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.
