About Lasix

Why should Lasix not be prescribed?

If you are sensitive to or have ever had an allergic reaction to Lasix or diuretics, or if you are unable to urinate, you should not take this medication.

Special warnings about Lasix

Lasix can cause your body to lose too much potassium. Signs of an excessively low potassium level include muscle weakness and rapid or irregular heartbeat. To improve your potassium level, your doctor may prescribe a potassium supplement or recommend potassium-rich foods, such as bananas, raisins, and orange juice.

Make sure the doctor knows if you have kidney disease, liver disease, diabetes, gout, or the connective tissue disease, lupus erythematosus. Lasix should be used with caution.

If you are allergic to sulfa drugs, you may also be allergic to Lasix.

If you have high blood pressure, avoid over-the-counter medications that may increase blood pressure, including cold remedies and appetite suppressants.

Your skin may be more sensitive to the effects of sunlight.
