Common use
Triamterene is a potassium-sparing diuretic used to eliminate excess fluid from the body without significantly reducing potassium levels. It is typically prescribed for fluid retention (edema) associated with congestive heart failure, kidney dysfunction, or cirrhosis, and is also used to manage high blood pressure.
By promoting urination while conserving potassium, Triamterene helps relieve swelling and reduce cardiovascular strain.
Dosage and direction
Take Triamterene exactly as recommended by your healthcare provider. Most patients take it once or twice per day, preferably with food to minimize digestive upset.
Swallow the capsule whole with water. Avoid crushing or chewing it.
To prevent sleep disturbances from nighttime urination, avoid taking this medication late in the day.
Do not adjust your dose unless instructed by a doctor.
Precautions
Before starting treatment with Triamterene, inform your physician if you have:
Kidney impairment
Diabetes

Missed dose
If you miss a scheduled dose, take it as soon as possible. If your next dose is near, skip the missed one. Never double up to compensate.
Overdose
Signs of overdose may include severe dizziness, muscle weakness, nausea, or dangerously high potassium levels. Seek emergency assistance without delay if overdose is suspected.
