Oral Rehydration Salts

Oral Rehydration Salts (ORS) is a WHO-formulated dry mixture of electrolytes and carbohydrates (dextrose). When dissolved in water, it creates an isotonic solution that facilitates rapid absorption of water and key electrolytes in the small intestine, reversing dehydration and maintaining physiological fluid balance.

Dosage by Body Weight

Always dissolve the powder in the exact volume of clean drinking water specified on the package (usually 200ml or 1 Liter). Do not boil the solution after reconstitution. Consume in small, frequent sips. Discard any unused solution after 24 hours if refrigerated, or after 1 hour if kept at room temperature.
