Oral Rehydration Salts Sachet: Uses, Dosage, Side Effects, Precautions and Alternates

Quick overview

Oral Rehydration Salts (ORS) Sachet is a mixture of electrolytes, such as sodium and potassium, and glucose, dissolved in water. It is used to replace fluids and salts lost during dehydration caused by diarrhoea, vomiting, fever, or heavy sweating. ORS works by using glucose to help the body absorb sodium and water more quickly through the intestine. It is available as sachets, drinks, ice blocks, and effervescent tablets.

What is Oral Rehydration Salts Sachet

Oral Rehydration Salts (ORS) is a mixture of electrolytes (such as sodium and potassium) and glucose (sugar) that is dissolved in water. It is used to replace fluids and salts that the body loses during dehydration caused by conditions like diarrhoea, vomiting, fever, or heavy sweating.

Oral Rehydration Salts Sachet uses

• Treating dehydration caused by diarrhoea, vomiting, fever or heavy sweating
• Treating moderate dehydration in children and adults
• Helping maintain fluid and electrolyte balance during prolonged physical activity in heat or mild diarrhoea

Benefits of Oral Rehydration Salts Sachet

• Prevents and treats dehydration caused by diarrhea
• Replaces lost fluids and electrolytes
• Helps restore sodium and potassium balance
• Supports rehydration during vomiting and other fluid loss
• Suitable for children and adults when correctly prepared

How Oral Rehydration Salts Sachet works

ORS works because sodium and glucose are absorbed together by special transporter proteins in the small intestine, and water follows along with them. This is why ORS contains both sugar and salt together — glucose helps the body take in sodium, and this pulls water into the body faster than water alone.

Oral Rehydration Salts Sachet dosage

Wash your hands, then wash the container and utensil you will use with soap and clean water before preparing the solution. Mix the ORS powder only with clean drinking water; for infants, use boiled and cooled water. Do not add extra powder, sugar, or salt to the mixture, and do not mix it with milk or juice.

If you cannot drink the full amount at once, take small sips over a longer period; using a straw or chilling the solution may help. Other medicines can generally be taken at the same time as ORS if needed.

Avoid fizzy drinks, undiluted juices, tea, coffee and sports drinks while treating dehydration, as their high sugar content can worsen dehydration. Do not use ORS to treat diarrhoea for more than 2 to 3 days unless a healthcare provider tells you to.

If sick (vomiting) within 30 minutes of taking a dose, take another dose; if sick after more than 30 minutes, wait until the next loose bowel motion before taking more. If unsure how much fluid a vomiting child has kept down, it is better to give more rather than less of the solution.

Warnings and precautions

• People with kidney disease should talk to a pharmacist or healthcare provider before using ORS, because the sodium and potassium in it may not be suitable for them.
• Use ORS with caution if you have a kidney disorder, diabetes, heart failure, or are taking heart disease or blood pressure medications. A doctor can determine if it's safe for you.
• If ORS isn't prepared or used correctly, it can cause salt toxicity, also known as hypernatremia.
• ORS should generally only be used when prescribed or recommended by a doctor, since using it when you don't actually need it makes salt toxicity more likely.
• If you have diabetes, ORS can affect your blood glucose, so check with a pharmacist or healthcare provider and monitor your blood glucose more closely while unwell.
• Homemade ORS mixtures can be risky because too much salt can be harmful, especially for infants and young children; it's not recommended to treat dehydration with homemade ORS.

When to see a doctor

• Always see a healthcare provider urgently if a baby under 6 months old has vomiting or diarrhoea, since babies can quickly become dehydrated and unwell.
• Get urgent medical help if a child or someone you're caring for is drowsy and hard to wake, has a lot of watery diarrhoea, is vomiting and can't keep fluids down, has blood in their stool, starts vomiting green fluid, has severe stomach pain, shows signs of dehydration, or has diarrhoea or vomiting lasting more than 10 days.
• Severe dehydration is a medical emergency — get emergency help right away if there is no sweat or tear production, ongoing dizziness, fast heart rate, rapid breathing, or dark urine.
• See a doctor if you experience nausea, vomiting, weakness, poor appetite, confusion, or excessive thirst after taking ORS, as these may be signs of salt toxicity.
• If symptoms worsen or a severe reaction occurs while using ORS, stop using it and seek medical help immediately.
