When to take

Expand All | Collapse All

Although Gaviscon® can be taken anytime you have acid reflux or heartburn, it’s best to avoid taking Gaviscon® before a meal. Since it forms a foam barrier that sits on top of stomach acid, the food passing through the esophagus (throat) into the stomach can disrupt this barrier and compromise its effectiveness.

As soon as you start experiencing acid reflux or heartburn symptoms.

Since Gaviscon® works quickly, you can eat or drink again as soon as your symptoms subside. However, keep in mind that eating or drinking will break the foam barrier, and likely reduce the benefits.

How it works

Expand All | Collapse All

Gaviscon® forms a barrier on top of stomach contents that can be expected to last up to four hours. Traditional antacids generally last approximately thirty to sixty minutes.

Yes. The protective foam barrier is activated and starts to form when the Gaviscon® tablet is chewed. Gaviscon® liquid requires contact with stomach acid to trigger the foaming barrier.

Chewing on the tablet is what activates the foam and starts to create the protective barrier. Sucking on the tablets doesn’t allow the foam barrier to form all at once, which may reduce the product’s effectiveness. The tablets are also large, and not designed to be swallowed whole.
