Gaviscon is a brand of medication that provides relief from heartburn and indigestion. Gaviscon tablets typically contain a combination of two main ingredients: an antacid and an alginate.

Antacid: The antacid component helps to neutralize stomach acid. Common antacid ingredients include aluminum hydroxide, magnesium carbonate, and/or sodium bicarbonate.
Alginate: The alginate forms a protective layer on the surface of the stomach contents, helping to prevent stomach acid from flowing back into the esophagus. This can be particularly helpful in cases of acid reflux.

Dosage: Take the recommended dosage as directed. This is usually based on factors such as age and the severity of symptoms. Do not exceed the maximum dosage specified on the packaging.
