What is Osmitrol?
Osmitrol is a diuretic.
Osmitrol is used to force urine production in people with acute (sudden) kidney failure. Increased urine production helps to keep the kidneys from shutting down, and also speeds up elimination of certain toxic substances in the body.
Osmitrol is also used to reduce swelling and pressure inside the eye or around the brain.
Osmitrol may also be used for purposes not listed in this medication guide.
You should not receive Osmitrol if you have severe kidney disease, lung swelling or congestion, severe dehydration, bleeding in your brain not caused by surgery, or if your kidneys have already shut down and you are unable to urinate.
