Hypotonic saline

Hypotonic saline is a type of intravenous (IV) fluid that contains a lower concentration of salt (sodium) than your blood. When delivered into the bloodstream, it helps to rehydrate cells by drawing water into them, which can be useful for treating dehydration or certain medical conditions. Since it has less salt than your blood, it can lower the overall salt level temporarily. Medical professionals carefully monitor its use to ensure it corrects hydration without causing issues like swelling or electrolyte imbalances. Hypotonic saline is one of several IV fluids used to maintain proper fluid and electrolyte balance in the body.
