What Does This Medicine Actually Do?
Simply put, this medicine is a type of water pill, also known as a diuretic. It helps your kidneys pull extra water and salt out of your blood. That extra fluid then leaves your body through your urine.
Imagine your blood vessels are like water hoses. When too much water fills those hoses, the pressure inside goes up. By removing that extra fluid, this medicine lowers the pressure and keeps your blood flowing smoothly.
This capsule or tablet contains two different medicines mixed together: triamterene and hydrochlorothiazide. Both drugs work as a team to control your blood pressure. Sometimes, doctors also prescribe it for other health conditions. If you have questions about why you take it, ask your doctor.

Never take two doses at the same time to make up for a missed pill. Taking extra medicine can cause your blood pressure to drop too low.
