Racecadotril: Uses, Side Effects & Safety

What it is and what it's used for

Racecadotril is an anti-diarrhoea medicine that reduces the amount of water secreted into the intestines, so stools become less watery and less frequent. It is used for the short-term management of sudden (acute) diarrhoea in adults and children — for example diarrhoea that starts with a stomach infection or a food upset. Unlike loperamide, it does not slow the movement of the gut; it works only on the secretion of water and salts.

Racecadotril is always used TOGETHER with fluids and oral rehydration salts (ORS) — it is not a substitute for them. It is generally sold over the counter in India, but it should not be used when diarrhoea may be due to a serious infection — for example when there is blood or mucus in the stool, or a high fever — because those situations need a doctor's treatment.

How it works (simple language)

In diarrhoea, the intestines secrete too much water and salt into the stool, making it watery. The body normally produces natural substances called enkephalins that help control this secretion, but they are quickly broken down by an enzyme called enkephalinase. Racecadotril blocks this enzyme, so the enkephalins last longer and the gut secretes less water — the stools become firmer and less frequent.

Importantly, racecadotril does this without slowing down the gut's natural movement, which is why it is considered a gentler option and is commonly used for children. The medicine is thought to act mainly in the intestines, and it does not affect the brain in the way some other anti-diarrhoea medicines do.

Dosage forms available in India (general info only)

Racecadotril is commonly available in India as 100 mg capsules (mostly for adults and older children) and as oral granule sachets (mostly for younger children, to be mixed in water or food). Well-known brands include Enuff and Hidrasec, though many generic brands are available and brands vary between pharmacies.

Never decide the dose yourself from this article. Always follow your doctor's prescription or the directions on the pack, and check with your pharmacist if you are unsure — especially for children, where the dose depends on the child's weight and age.

Side effects

Common: Headache is the most commonly reported side effect. Some people also experience nausea, vomiting, stomach ache or abdominal pain, flatulence (gas), dizziness, or constipation. Skin rashes have also been reported in some users.

Serious — seek medical care: Signs of an allergic reaction such as swelling of the face, lips, tongue or throat, rash or itching, or difficulty breathing. Stop the medicine and get care for severe or worsening abdominal pain, a swollen or hard belly, vomiting that does not stop, signs of severe dehydration such as very little urine, extreme thirst, dry mouth, sunken eyes, unusual drowsiness or weakness — especially in children — and any sign that the illness is worsening, such as blood or mucus in the stool or high fever.

Precautions and warnings

• Not for bloody or feverish diarrhoea: Do not use racecadotril if the stool contains blood or mucus, or if there is a high fever. These can be signs of an infection (such as dysentery) that needs a doctor's diagnosis and treatment.
• ORS and fluids come first: Racecadotril only reduces the symptom. Dehydration — the loss of water and salts — is the real danger in diarrhoea, especially in children and the elderly, so oral rehydration salts and plenty of fluids must be given alongside.
• Very young infants: It is generally not recommended for infants under 3 months of age; any use in very young babies must be on a doctor's advice with an exact dose.
• Stop if it does not help: If diarrhoea does not improve within a few days of using racecadotril, or gets worse, stop and see a doctor — the cause may need proper treatment.
• Kidney or liver problems: The body processes racecadotril through the liver and kidneys, so people with kidney or liver disease should use it only on a doctor's advice.
• Chronic or recurring diarrhoea: Racecadotril is meant for short-term, sudden diarrhoea. Ongoing or repeatedly recurring diarrhoea needs a doctor to find the underlying cause.
• Do not delay care for warning signs: If the sick person — especially a child — is drinking very little, passing very little urine, crying without tears, or becoming unusually sleepy or unresponsive, get medical help urgently rather than relying on the medicine.

Interactions (general)

Racecadotril has few known interactions with other medicines, but you should still tell your doctor about ALL medicines the person is taking, including herbal and ayurvedic products. Other medicines that affect the gut, or medicines for long-term conditions in people with kidney or liver problems, need a doctor's review. Alcohol is best avoided while ill with diarrhoea, as it can worsen dehydration.

Pregnancy and breastfeeding (general guidance)

There is limited safety data for racecadotril in pregnancy, and it should be used only if the doctor considers it necessary. It is not known whether it passes into breast milk in significant amounts; consult your doctor before using while breastfeeding.

Storage

Store at room temperature, away from moisture and direct sunlight, and keep the pack out of reach of children. Granule sachets should be used as directed on the pack once opened or mixed. Do not use past the expiry date.

When to see a doctor

See a doctor if: diarrhoea does not improve within a couple of days despite racecadotril, there is blood or mucus in the stool, there is a high fever, the person cannot keep fluids down, a child or elderly person has diarrhoea, or diarrhoea keeps coming back. Seek emergency care for signs of severe dehydration — very little or no urine, extreme thirst, dry mouth and tongue, sunken eyes, unusual drowsiness or confusion — or severe abdominal pain with a swollen belly.

FAQs

1. How is racecadotril different from loperamide?

Both control diarrhoea, but they work differently. Loperamide slows the movement of the gut, while racecadotril only reduces the amount of water the gut secretes into the stool, without affecting gut movement. This is why racecadotril is often preferred for children, and why it is generally considered gentler on the stomach.

2. Can children take racecadotril?

Yes, it is commonly prescribed for children with acute diarrhoea, and it comes in child-friendly granule sachets. However, it is not generally recommended for infants under 3 months, and the dose for children depends on their weight and age — so always follow the doctor's or pack's directions, and make sure the child keeps getting ORS and fluids.

3. Do I still need ORS if I am taking racecadotril?

Yes — always. Racecadotril only makes the stools less watery; it does not replace the water and salts your body has already lost. ORS and plenty of fluids are the real treatment for diarrhoea, and skipping them while taking racecadotril is the most dangerous mistake.

4. When should I stop racecadotril and see a doctor?

Stop and see a doctor if diarrhoea does not get better within a few days, if there is blood or mucus in the stool, if there is a high fever, if the person cannot keep fluids down, or if there are any signs of severe dehydration — especially in children. Ongoing or recurring diarrhoea always needs a doctor to find the cause.
