Lasix 40 mg Tablet is a diuretic. It removes extra water and certain electrolytes from the body by increasing the amount of urine produced. In doing so, it causes potassium loss.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
An overdose of this medicine can cause severe dehydration, a sharp fall in blood pressure and dangerous salt imbalances. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
