There are some medicines that may affect the way perindopril works.

 - medicines that make you pee more (diuretics), such as furosemide
 - medicines that can increase the amount of potassium in your blood, such as spironolactone, triamterene, amiloride, potassium supplements, trimethoprim (for infections) or heparin (for preventing blood clots)
