Gaviscon (active ingredient: sodium alginate) is an over-the-counter medication commonly used to relieve symptoms of acid reflux, heartburn, and indigestion. Sodium alginate is derived from seaweed and works by forming a protective barrier that floats on top of the stomach’s contents. This helps to prevent acidic stomach content from rising into the esophagus, which causes the burning sensation associated with heartburn and reflux. In combination with other ingredients, such as calcium carbonate and sodium bicarbonate, Gaviscon can provide fast relief from discomfort.

Unlike many traditional antacids that simply neutralize stomach acid, Gaviscon offers a dual-action formula by both neutralizing acid and creating a physical barrier that blocks acid reflux. This makes it a preferred choice for those who suffer from frequent or severe heartburn, particularly after meals or when lying down.

Gaviscon is available in both liquid and tablet forms, providing options depending on individual preferences. Unlike other OTC antacids, Gaviscon is unique in its use of sodium alginate to form a physical barrier against reflux, which may offer more effective relief for individuals prone to acid regurgitation.

Dosage

The usually recommended dose of Gaviscon is 10-20 mL of liquid or 2-4 tablets taken after meals and at bedtime. The dosage may be varied based on the severity of symptoms, but it is essential to follow the instructions on the packaging. If the symptoms persist despite use of the product, consult a healthcare provider for personalized recommendations.

Storage

Store Gaviscon at room temperature (20-25°C / 68-77°F). Keep it tightly sealed and out of the reach of children. Avoid exposing the box to excessive heat or freezing conditions. Read more in our blog on safe medicine management.
