Diuril (chlorothiazide) treats fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or kidney disorders, or edema caused by taking steroids or estrogen. This medication is also used to treat high blood pressure (hypertension). It is a thiazide diuretic (water pill). This medication is available in generic form. Common side effects include dizziness, lightheadedness, headache, blurred vision, loss of appetite, stomach upset, diarrhea, or constipation as your body adjusts to the medication. You may also experience decreased sexual ability or increased sensitivity to the sun.
The usual adult dosage of Diuril for edema is 500 mg to 1000 mg (10 mL to 20 mL) once or twice a day. The usual adult starting dosage for hypertension is 500 mg or 1000 mg (10 mL to 20 mL) a day as a single or divided dose. Pediatric dose is determined by the child's weight. Diuril may interact with other medicines that cause light-headedness (i.e., cold or allergy medicine, narcotics, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety), lithium, digoxin, cholestyramine, colestipol, steroids, other blood pressure medications, aspirin, NSAIDs (non-steroidal anti-inflammatory drugs), insulin or oral diabetes medicines. Diuril should be used only when prescribed during pregnancy. This drug passes into breast milk. While there have been no reports of harm to nursing infants, consult your doctor before breast-feeding.
