Gaviscon Double Action Tablet 16s (Box)

Gaviscon Double Action Tablet is a trusted over-the-counter antacid and alginate-based medicine that many Malaysians reach for when they need fast relief from uncomfortable stomach symptoms. It contains two active ingredients — sodium alginate and sodium bicarbonate, along with calcium carbonate — working together to form a protective raft over stomach contents. Like most medicines, it can occasionally cause mild side effects such as nausea, bloating, constipation, or an upset stomach in some people. If you are pregnant, breastfeeding, on a low-sodium diet, or managing kidney problems, there are a few things you should check with your pharmacist or doctor before taking it. It is widely available without a prescription, making it a convenient option to keep on hand for those moments when you need it most.

Drug & Food Interactions of Gaviscon Double Action Tablet

Drug Interactions:

• Antibiotics (e.g., tetracyclines, fluoroquinolones): Antacids can bind to these antibiotics and reduce their absorption. Maintain a gap of at least 2 hours between taking Gaviscon and these antibiotics.
• Iron supplements: Calcium carbonate in Gaviscon can reduce the absorption of oral iron. Take iron supplements at least 2 hours apart from this product.
• Thyroid medications (e.g., levothyroxine): Antacids may impair the absorption of thyroid hormones. Separate dosing by at least 4 hours.
• Bisphosphonates (e.g., alendronate): Calcium-containing antacids can interfere with bisphosphonate absorption; these should not be taken together.
• Certain antifungals (e.g., ketoconazole, itraconazole): Antacids may reduce the effectiveness of these medicines by altering stomach pH.
• Enteric-coated tablets: Taking antacids alongside enteric-coated medicines may cause premature dissolution of the coating in the stomach.

Food Interactions:

• High-sodium foods: Since Gaviscon Double Action contains sodium, combining it with a high-sodium diet may be a concern for individuals managing blood pressure or heart conditions.
• Dairy products and calcium-rich foods: Consuming large amounts of calcium-rich foods alongside this product may contribute to excessive calcium intake over time.
• Alcohol: While not a direct chemical interaction, alcohol can worsen acid reflux and stomach irritation, potentially reducing the overall comfort and effectiveness of the treatment.

Always inform your pharmacist or doctor about all medications, supplements, and health conditions before starting any new medicine.
