This medicine helps stop reflux, which is when your baby's stomach contents flow back up into their foodpipe, causing them to be sick after feeds.

What is Gaviscon infant used for?

  • Treating gastro-oesophageal reflux in babies, including reflux associated with a hiatus hernia.
  • Preventing regurgitation of the stomach contents in babies.

Regurgitation of the stomach contents is common in babies and infants because the muscular ring at the lower end of the food pipe (oesophagus) isn't yet fully developed. It can allow the contents of the stomach to flow back into the food pipe when the stomach is full. This is called reflux and may result in small amounts of milk and stomach acid being brought back up into the mouth after a feed (sometimes called posseting).

Some infants are particularly susceptible to reflux, especially if they are very hungry prior to a feed or swallow more air than normal as they feed. In some babies it's merely the appropriate response to overfeeding. It's no cause for concern if the baby is happy, feeds well and gains weight. In this case the reflux normally resolves itself as the infant starts to eat more solids and spends more time in an upright position.

Gaviscon infant may be recommended by a doctor or pharmacist if your baby is not gaining weight properly or has complications of the reflux, such as discomfort or distress. It may also be recommended if the child has a hiatus hernia that is causing the reflux. It should only be given on the advice of a medical professional.

How does Gaviscon infant work?

Gaviscon infant sachets contain two active ingredients, sodium alginate and magnesium alginate. These are naturally occurring substances found in a particular type of seaweed.

The active ingredients are not absorbed into the baby's bloodstream. Instead they work by reacting with the stomach contents to form a gel. This gel thickens the stomach contents, making it more difficult for a feed to reflux back into the food pipe and be brought back up.

How do I give Gaviscon infant?

  • The amount of medicine to give and how to give it depends on how much the baby weighs and how they are being fed.
  • The contents of the sachets should only be mixed up as needed; the medicine should not be mixed up and saved for later.
  • Babies weighing less than 4.5kg (10lb) should be given the contents of one sachet with each feed.
  • Babies weighing more than 4.5kg (10lb) should be given the contents of two sachets with each feed.
  • Breastfed babies: Mix the contents of each sachet with 5ml (1 teaspoon) of cooled, boiled water until you have a smooth paste. Then add another 10ml (2 teaspoons) of cooled, boiled water and mix. Give this part way through each feed or meal using a spoon or feeding bottle.
  • Bottlefed babies: Mix each sachet into 115ml (4 fl oz) of feed in the bottle. Shake well. Feed your baby as normal.
  • Babies that have been weaned: Mix the contents of each sachet with 5ml (1 teaspoon) of cooled, boiled water until you have a smooth paste. Then add another 10ml (2 teaspoons) of cooled, boiled water and mix. Give this at the end of each meal using a spoon or feeding bottle.
  • Do not give Gaviscon infant more than six times in 24 hours. The medicine contains sodium and excessive use could raise the amount of sodium in the child's blood.

If you forget to give a dose you should just leave out that dose. Do not give a double dose with the next feed.

  • If your baby's symptoms don't improve or get worse after giving them Gaviscon infant you should consult your doctor for advice.
  • Do not use this medicine for more than seven days without having your baby reviewed by your doctor.

  • Babies with known or suspected kidney problems.
