Triamterene
Summary
Triamterene is used to treat edema, or swelling, associated with conditions like congestive heart failure, liver cirrhosis, and nephrotic syndrome. It can also be used for conditions like steroid-induced edema and secondary hyperaldosteronism.
Triamterene works by inhibiting sodium reabsorption in the kidneys. This leads to increased excretion of water and sodium, while conserving potassium. This helps reduce fluid retention and swelling.
The usual starting dose for adults is 100 mg twice daily after meals. The total daily dosage should not exceed 300 mg. Always follow your doctor's advice for dosage.
Common side effects include dizziness, headache, nausea, and vomiting. Serious adverse effects can include hyperkalemia, muscle weakness, and irregular heartbeat.
Triamterene should not be used with other potassium-sparing agents or in patients with elevated serum potassium. It can cause hyperkalemia, especially in patients with renal impairment or diabetes. Regular monitoring of potassium levels is crucial.

Triamterene can interact with other medications, increasing the risk of adverse effects. Major interactions include ACE inhibitors and potassium-sparing diuretics, which can raise potassium levels, leading to hyperkalemia. Nonsteroidal anti-inflammatory drugs (NSAIDs) can reduce the effectiveness of Triamterene and affect kidney function. Always inform your doctor about all medications you are taking to manage potential interactions and ensure safe treatment.

You won't experience cravings for this medication or feel compelled to take more than prescribed. If you have concerns about medication dependence, you can feel confident that Triamterene doesn't carry this risk.
Is Triamterene safe for the elderly?
Elderly individuals are more vulnerable to the safety risks of Triamterene due to potential changes in kidney function and increased sensitivity to side effects like dehydration and high potassium levels.
