What should you know about oral rehydration salts for adults?

For adults, oral rehydration salts can restore water and electrolytes lost through diarrhoea, vomiting, heat, or heavy sweating. The prepared drink works by pairing glucose with salts to help the bowel absorb fluid. It supports hydration; it is not an anti-diarrhoeal medicine or an antibiotic.

Dry mouth, thirst, dizziness when standing, headache, dark urine, or passing urine less often can occur with dehydration. These signs have other possible causes, so consider the whole illness and the person’s medical history. An adult who has diabetes, kidney problems, heart failure, or a prescribed fluid limit should check with a clinician before using large amounts.

A packet is designed to be diluted in a specific amount of water. Changing that balance can increase the salt load or reduce its usefulness.

Read the label, wash your hands, and dissolve the entire sachet in the required amount of safe water. Sip steadily rather than drinking a large volume quickly. After vomiting, wait a short while, then try again with tiny, regular sips. Continue nourishing foods as tolerated and avoid alcohol while recovering.

Never add extra sugar or salt, and do not use fizzy drinks as the mixing liquid. Prepare fresh solution according to the product instructions and discard it as directed.

Get urgent medical help if you cannot keep fluids down, become confused or faint, have severe weakness, pass very little urine, develop blood in vomit or stool, or have severe abdominal pain. Contact a clinician if diarrhoea or vomiting persists, follows recent travel, or is accompanied by fever or a significant medical condition.

Ask whether your symptoms suggest dehydration, which fluid is appropriate with your medicines, and what change would mean that home hydration is no longer enough.
