Gaviscon Double Action Mint Suspension is a 300ml oral medication that provides fast and effective relief from heartburn and indigestion. The mint-flavored liquid formula contains sodium alginate, sodium bicarbonate, and calcium carbonate that work together to create a protective barrier and neutralize excess stomach acid. This double action formula works in two ways - it forms a protective layer that prevents stomach acid from flowing back into the esophagus while also neutralizing excess acid. The mint flavor makes it pleasant to take. The 300ml bottle comes with a measuring cup for accurate dosing. For best results, shake well before use and take after meals and before bedtime as needed. Always follow the recommended dosage instructions on the label.
