Lasix is a loop diuretic used to treat high blood pressure or water retention (swelling) associated with congestive heart failure, liver disease, or kidney disease. The medicine prevents your body from absorbing too much salt. As a result it allows the salt to be passed in your urine. It is also used to control high blood pressure. Furosemide works by increasing the amount of urine produced and excreted, and by removing excessive water (edema).
It is recommended to take according to your doctor's instructions. The recommended adult starting dose for treating edema is 40 mg to 80 mg. If a satisfactory result occurs within 6 hours, the dose may be decreased or kept the same. If edema continues longer than 6 hours, the dose may be increased by 20 mg to 40 mg. When treating hypertension (high blood pressure), the dose of furosemide starts at 20 mg to 40 mg twice a day.
Before starting your treatment with Lasix please inform your doctor if you have kidney disease, liver disease, gout, lupus, diabetes, or an allergy to sulfa drugs. It is not recommended to take the medicine if you are pregnant or breastfeeding. This drug may make you dizzy or cause blurred vision. Seniors may be more likely to experience increased side effects from furosemide.
The patients with the following conditions can't use Lasix: hypersensitivity, severe liver failure, acute kidney failure with anuria, liver coma and precoma, stenois of urethra, acute glomerulonephritis, urinary tract obstruction, precoma, hyperglycemic coma, gout, arterial hypotension, heart attack, pancreatitis and others.
