Lasix Tablets (Furosemide) treats fluid retention in people with congestive heart
failure, liver disease, or a kidney disorder such as nephrotic
syndrome. This medication is also used to treat high blood pressure.
To be sure this medication is not causing harmful effects, your blood
will need to be tested on a regular basis. Your kidney or liver
function may also need to be tested. Do not miss any scheduled
appointments.
Lasix Tablets (Furosemide) will make
you urinate more often and you may get dehydrated easily. Follow your
doctor's instructions about using potassium supplements or getting
enough salt and potassium in your diet.
Avoid becoming dehydrated. Follow your doctor's instructions about the
type and amount of liquids you should drink while you are taking
furosemide.
If you are being treated for high blood pressure, keep using
Lasix Tablets (Furosemide) even if you feel fine. High blood pressure often has no symptoms.
Lasix Tablets
(Furosemide) is a loop diuretic. Loop diuretics make the kidneys
eliminate larger amounts of electrolytes (especially sodium and
potassium salts) and water than normal (diuretic effect). Loop
diuretics are useful for treating many conditions in which salt and
water retention (eg, edema, swelling) is a problem.
