While mannitol is a crucial osmotic diuretic used to reduce intracranial and intraocular pressure, its administration is not without significant risks. It is vital for healthcare providers and patients to understand what are the two conditions in which the use of mannitol is contraindicated to prevent life-threatening complications.

According to the International Food Information Council, excessive consumption of sugar alcohols like mannitol can cause gastrointestinal discomfort, including gas, bloating, and diarrhea. This occurs because mannitol is poorly absorbed by the body, creating an osmotic effect in the intestines that draws in water, a key mechanism behind its laxative property.

As a potent osmotic diuretic, mannitol is used in critical care to reduce swelling in the brain or eyes, but its primary action can cause a major adverse effect: significant shifts in the body's fluid and electrolyte balance. This can lead to serious complications if not carefully monitored and managed by healthcare professionals.

Mannitol was one of the first osmotic diuretics developed and is a versatile medication with a unique mechanism of action. What is the drug mannitol used for? It is primarily administered to address medical conditions involving excess fluid and pressure, particularly within the brain and eyes, by creating an osmotic gradient.
