Medication details


Gaviscon Infant Sachets 1+ Years is a reputable and widely recognized over-the-counter medication formulated to alleviate the discomfort associated with gastroesophageal reflux in infants and children aged 1 year and above. Gastroesophageal reflux occurs when stomach contents flow back into the esophagus, causing symptoms like regurgitation, heartburn, and irritability in infants. This specially formulated medication aims to provide relief from these distressing symptoms, promoting a more comfortable feeding and sleeping experience for both the child and the parents.

The unique aspect of Gaviscon Infant Sachets is its dual-action approach to managing reflux symptoms. It contains two active ingredients: sodium alginate and calcium carbonate. Sodium alginate, derived from seaweed, forms a protective layer on top of the stomach contents. This layer acts as a barrier, reducing the likelihood of stomach acid flowing back into the esophagus. Calcium carbonate, on the other hand, acts as an antacid by neutralizing excess stomach acid. This combination of ingredients offers a comprehensive solution to effectively manage infant reflux symptoms.

Gaviscon Infant Sachets are a trusted choice among parents and caregivers seeking a non-prescription solution to ease the discomfort caused by gastroesophageal reflux. It's important to note that Gaviscon Infant Sachets are not a cure for underlying conditions causing reflux; rather, they provide symptomatic relief to enhance the quality of life for both the child and their caregivers.


Using Gaviscon Infant Sachets is straightforward and should be done following the provided instructions:
Dosage: For children aged 1 year and above, administer one sachet after each feed. It is recommended to use Gaviscon Infant Sachets up to a maximum of six times within a 24-hour period.
Preparation: Open the sachet and empty its contents into a small amount of cool, previously boiled water. Stir gently until a smooth paste is formed.
Administration: Feed the paste to the child using a spoon or an appropriate dispenser. It is crucial to administer the mixture immediately after the regular feed.
Frequency: Gaviscon Infant Sachets can be administered with every feed as required. However, it's essential to adhere to the recommended maximum daily dosage.


The active ingredients in Gaviscon Infant Sachets include:
Sodium Alginate: Derived from natural sources such as seaweed, sodium alginate contributes to the formulation's unique mechanism. It forms a gel-like layer that floats on top of the stomach contents, acting as a physical barrier to prevent reflux.
Calcium Carbonate: This antacid ingredient works alongside sodium alginate to neutralize excess stomach acid, further aiding in reducing reflux symptoms.

Side Effects

Gaviscon Infant Sachets are generally well-tolerated; however, as with any medication, there is a possibility of side effects:
Constipation: The presence of calcium carbonate in Gaviscon Infant Sachets might occasionally lead to mild constipation. Maintaining adequate fluid intake and incorporating dietary fiber can help manage this effect.
Allergic Reactions: Although rare, some individuals may experience allergic reactions to certain components of the product. If you observe any signs of an allergic reaction, such as rash, itching, or swelling, discontinue use and seek medical attention.
It's important to consult a healthcare professional before using Gaviscon Infant Sachets, especially if your child has underlying health conditions or is taking other medications.


While Gaviscon Infant Sachets are considered safe for most children aged 1 year and above, it's essential to keep certain considerations in mind:
Professional Advice: Before introducing any new medication, particularly for infants and young children, seek advice from a healthcare professional. They can provide personalized guidance based on the child's specific health needs.
Dosage Adherence: Adhere to the recommended dosage and avoid exceeding the maximum daily intake to prevent potential adverse effects.
Underlying Conditions: If your child has an existing medical condition or is on other medications, consult a healthcare provider before using Gaviscon Infant Sachets.
Allergies: Thoroughly review the ingredient list to ensure your child is not allergic to any of the components. When in doubt, consult a healthcare professional.
Storage: Store Gaviscon Infant Sachets in a cool, dry place, out of reach of children.
