Heartburn

Gaviscon works by forming a foam-like layer on top of the stomach’s contents, preventing acid from rising into the oesophagus. This is made possible by its key ingredient, sodium alginate, which reacts with stomach acid to create a protective barrier. At the same time, antacids such as calcium carbonate and sodium bicarbonate neutralise excess acid, providing further relief from burning sensations and discomfort. Unlike some traditional antacids, Gaviscon doesn’t just neutralise stomach acid - it actively prevents reflux, offering longer-lasting protection.

Medication details

Description

Gaviscon chewable tablets offer fast and effective relief from heartburn and indigestion. These convenient tablets are designed to neutralise excess stomach acid and form a protective barrier, preventing acid from rising into the oesophagus and causing discomfort. Whether you've indulged in a hearty meal or are experiencing symptoms during pregnancy, Gaviscon chewable tablets can help soothe the burning sensation and provide long-lasting comfort.

Directions

For optimal results, chew 2 to 4 tablets thoroughly after meals and at bedtime, up to four times a day, or as directed by your doctor. After chewing, it's beneficial to follow with half a glass of water or another liquid. Avoid swallowing the tablets whole, as chewing ensures the active ingredients are properly released to act effectively. Do not exceed 16 tablets in a 24-hour period.

Ingredients

Each Gaviscon chewable tablet contains 250 mg of sodium alginate, 106.5 mg of sodium bicarbonate, and 187.5 mg of calcium carbonate as active ingredients. Inactive components include xylitol, carmellose sodium, magnesium stearate, macrogol 20,000, mannitol (E421), copovidone, acesulfame-K, aspartame (E951), mint flavour, and carmoisine lake (E122). These tablets are free from sugar and gluten, making them suitable for individuals with dietary restrictions.

Side Effects

While Gaviscon chewable tablets are generally well-tolerated, some users may experience side effects. Common side effects include digestive disturbances such as bloating or flatulence. These symptoms are typically mild and temporary. If you experience any severe or persistent side effects, it's important to consult your healthcare provider promptly.

Warnings

Before using Gaviscon chewable tablets, consult your doctor if you are on a sodium-restricted diet, as each four-tablet dose contains 9.72 mmol of sodium. Additionally, if you have been advised to limit calcium intake, be aware that each four-tablet dose provides 7.5 mmol of calcium. If you are taking other medications, especially those for heart conditions or blood pressure, seek medical advice before starting Gaviscon, as antacids can interact with certain prescription drugs. Do not use this product for peptic ulcers without medical supervision. If symptoms persist after seven days of treatment, consult your doctor. Gaviscon chewable tablets are suitable for use during pregnancy and breastfeeding when taken as directed.
