How Heart Valve Problems Are Treated

Diuretics

Sometimes known as water pills, diuretics are medications that reduce the heart's workload by eliminating some of the fluid in the body through urination. Common diuretics include chlorthalidone, metolazone, amiloride, furosemide, spironolactone, and triamterene. These medications may cause dehydration, blurred vision, muscle cramps, tingling in the hands and feet, joint pain, ringing in the ears, and sweating. Dry mouth, sensitivity to light, increased thirst, and unusual bleeding or bruising have also been reported. Diuretics can also lower the levels of potassium and magnesium in the blood, and as a result, patients may need to take nutritional supplements for these. Sometimes, patients need to have blood tests to monitor their levels of these nutrients.
