Dyazide (Triamterene / Hydrochlorothiazide) is generally used to treat high blood pressure in patients. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This medication is a combination of two "water pills" (diuretics): triamterene and hydrochlorothiazide.
The combination of these two water pills is used by people who have developed or are currently at risk for having low potassium levels on hydrochlorothiazide. This medication can cause you to make more urine, which helps your body get rid of extra salt and water. Dyazide (Triamterene / Hydrochlorothiazide) can also reduce extra fluid in the body (edema) caused by conditions such as heart failure, liver disease, or kidney disease.
To comply with Canadian International Pharmacy Association regulations you are permitted to order a 3-month supply or the closest package size available based on your personal prescription. read more
Here are general precautions when taking Dyazide (Triamterene / Hydrochlorothiazide):
Category | Precaution |
General Precautions | Triamterene tends to conserve potassium and can cause hyperkalemia in the body, sometimes leading to cardiac irregularities. Electrolyte imbalances may be aggravated on use, as well. Dyazide can cause mild nitrogen retention, however, is reversible with intermittent therapy. Dyazide may also cause metabolic acidosis and may contribute to megaloblastosis in patients with depleted folic acid stores. Use with caution in patients with a history of renal stones. |
Laboratory Tests | Hyperkalemia is rare with adequate urinary output but possible with large doses over time. Serum potassium levels above 6 mEq/L require careful observation and treatment. Gradual withdrawal recommended to avoid rebound kaliuresis. |
Drug Interactions | Lithium: monitor serum levels due to increased risk of toxicity. NSAIDs: caution due to potential for acute renal failure. Potentiated effects with antihypertensives, other diuretics, anesthetics, muscle relaxants, ACE inhibitors. Avoid potassium-accumulating agents. |
Drug & Laboratory Test Interactions | Interferes with fluorescent measurement of quinidine. |
Carcinogenesis & Mutagenesis | Increased incidence of hepatocellular neoplasia in mice at high doses. No mutagenic effects in bacterial studies. |
Pregnancy | No teratogenic effects observed in animal studies. Use during pregnancy only if clearly needed. Crosses placental barrier. |
Nursing Mothers | Likely present in human milk. Use only if essential; patients should stop nursing right away. |
Pediatric Use | Safety and effectiveness not established in pediatric patients. |
