Dyrenium Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Dyrenium (triamterene) is used to treat fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or a kidney condition called nephrotic syndrome. It is also used to treat edema caused by having too much aldosterone in your body. Aldosterone is a hormone produced by the adrenal glands to help regulate the salt and water balance in your body. Dyrenium is a potassium-sparing diuretic (water pill). Common side effects include dizziness, tiredness, headache, stomach upset, or diarrhea as your body adjusts to the medication. You may also experience increased sensitivity to the sun.
The usual starting dose of Dyrenium when used alone is 100 mg twice daily after meals. Dyrenium may interact with lithium, insulin or oral diabetes medicine, ACE inhibitors, indomethacin or other NSAIDs (non-steroidal anti-inflammatory drugs). Tell your doctor all medications you use. Dyrenium should be used only when prescribed during pregnancy. This drug may pass into breast milk. Consult your doctor before breast-feeding.
