Indications

Glaucoma Edema

Mannitol is mainly given by IV infusion as an osmotic diuretic. Doctors use it to preserve kidney function in acute renal failure and to bring down raised intracranial and intraocular pressure. Mannitol also works as an irrigating solution during transurethral prostatic resection, where it helps prevent hemolysis and hemoglobin buildup. In acute drug poisoning, it helps when the poison leaves the body through the kidney. Besides these uses, mannitol gives symptomatic relief of edema and is used in reperfusion injury, termination of pregnancy and bowel preparation. So mannitol is indicated in renal insufficiency, reperfusion injury, raised intracranial pressure, bladder irrigation, raised intraocular pressure, bowel preparation, edematous status, as a prophylactic in renal failure, in the management of poisoning, and in termination of pregnancy.

⚠️ Always consult a registered physician before taking any medicine.

Pregnancy & Breastfeeding

Safety of intravenous Mannitol during pregnancy has not been established. It is also not known whether mannitol passes into breast milk, so it should be used only after carefully weighing the potential benefits against the possible risks.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Adults: The adult dose of Mannitol ranges from 50 to 100 gm by IV infusion. The rate of administration is usually adjusted to maintain a urine flow of at least 30 to 50 ml/hr. Total dosage, concentration and the rate of administration depends on fluid requirement, urinary output and the severity of the condition being treated. For renal insufficiency, adults are given 50 to 100 g of Mannitol at a rate adjusted to maintain a urine flow of at least 30 to 50 ml/hr, while children are given 2 gm/kg or 60 gm/m2 of body surface area over a period of 2 to 6 hrs. For cerebral edema, elevated intracranial pressure, elevated intraocular pressure and glaucoma, adults are given 1.5 to 2 gm/kg over a period of 30 to 60 minutes, while children are given 1 to 2 gm/kg body wt. or 30 to 60 gm/m2 of body surface area over a period of 30 to 60 mins. As adjunctive therapy for removal of toxic substances, adults are given 50 to 200 g of Mannitol at a rate adjusted to maintain a urine flow of at least 100 to 500 ml/hr, while children are given 2 gm/kg or 60 gm/m2 of body surface area. For termination of pregnancy, 50 gm of Mannitol (250 ml of Mannitol) is instilled into the amniotic cavity, which induces abortion in a high proportion of pregnancies.
