What is mannitol?
Mannitol is a diuretic that is used to reduce swelling and pressure inside the eye or around the brain.
Mannitol is also used to help your body produce more urine. This medicine is used in people with kidney failure, to remove excess water and toxins from the body.
Mannitol is sometimes given so that your body will produce enough urine to be collected and tested. This helps your doctor determine if your kidneys are working properly.
Mannitol may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before receiving mannitol?
You should not receive mannitol if you are allergic to it, or if you have:
- severe or long-term kidney disease;
- swelling or congestion in your lungs;
- severe heart failure;

How is mannitol given?
Mannitol is given as an infusion into a vein. A healthcare provider will give you this injection.
Mannitol must be given slowly, and you may receive the medication around the clock.
Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when mannitol is injected.
You will need frequent medical tests to be sure this medicine is not causing harmful effects. This will also help your doctor determine how long to treat you with mannitol.
This medicine may affect certain medical tests and you may have false results. Tell any doctor who treats you that you are using mannitol.
What happens if I miss a dose?
Because you will receive mannitol in a clinical setting, you are not likely to miss a dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid after receiving mannitol?
Follow your doctor's instructions about any restrictions on food, beverages, or activity.

Tell your doctor about all your other medicines, especially a diuretic or "water pill."
