Urinom Tamsulosin Hydrochloride Amitriptyline Hydrochloride
ModerateIn lab tests using liver enzyme samples (the cytochrome P450 system, which is how the liver breaks down many medicines), no interaction was seen at the liver-metabolism level between Tamsulosin and amitriptyline. The same was true for salbutamol, glibenclamide and finasteride. These were in vitro studies, done in the laboratory and not in patients.
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.
