Hydrochlorothiazide/triamterene, also known as co-triamterzide, is a fixed-dose combination medication of hydrochlorothiazide and triamterene.[2][3][4] It is used to treat high blood pressure and edema (swelling).[2][3][4] Specifically it is used in those who develop low blood potassium (hypokalemia) when on only hydrochlorothiazide.[2][3] It is taken by mouth.[2][3][4]

Side effects may include nausea, trouble sleeping, dizziness, feeling light headed with standing, kidney problems, allergies, and muscle cramps.[2][3] Other serious side effects may include high blood potassium.[2][3] Use in pregnancy and breastfeeding is not generally recommended.[2][3] Use in those with significant kidney problems is not recommended.[2][3] It decreases blood pressure mainly by hydrochlorothiazide while triamterene decreases the amount of potassium lost.[2][3]

The combination was approved for medical use in the United States in 1965.[5] In 2020, it was the 131st most commonly prescribed medication in the United States, with more than 4 million prescriptions.[6][7]
