Active Ingredient: Hydrochlorothiazide



Triamterene is a prescription drug used for the treatment of high blood pressure associated with liver cirrhosis, congestive heart failure, nephrotic syndrome as well as idiopathic and steroid-induced edema. Being a diuretic (water pill), here’s how Triamterene works:

  • the drug is in essence a combination of a thiazide diuretic and a potassium-sparing diuretic. It helps the kidney eliminate sodium (salt) and water from the body.
  • the elimination of sodium from the kidney and water helps alleviate symptoms associated with edema (water retention) and high blood pressure. The second component of the drug helps minimize potassium loss.

It may be used alone or in combination with other drugs as long as there are no bad interactions.

Precautions before using Triamterene

Your medical history will be put to scrutiny so that if you have liver problems, kidney problems, mineral imbalances (like low sodium levels in blood or high levels potassium in blood), gout or any condition that causes low folic levels in blood then your case is treated different. The same applies to expectant women and those nursing infants. If you have high blood sugar then the pharmacist will have to adjust your medication. Do not use Triamterene medication if:

  • you are allergic to its ingredients. Read the leaflet for list of all ingredients
  • you have a severe kidney problem or high blood potassium levels or if you are unable to urinate
  • you are taking another potassium sparing diuretic like spirinolactine or another drug containing Triamterene, a salt substitute or an aldosterone blocker. Your pharmacist will advise you on this.
  • if you are planning for a baby or if you’re pregnant or nursing a baby

All in all, schedule for an appointment with the doctor for proper dosage prescription.
