Gaviscon Double Action Mint is a 300ml oral suspension that provides fast and effective relief from heartburn and indigestion. The formula contains sodium alginate, sodium bicarbonate, and calcium carbonate, offering dual-action relief that can last up to 4 hours. This mint-flavored liquid medication works through a unique double action mechanism. When the liquid comes in contact with stomach acid, it forms a protective barrier (raft) that helps prevent acid reflux while also neutralizing excess stomach acid. The product comes in a convenient 300ml bottle with a measuring cap for accurate dosing. As this is a medicine, please consult the package insert for proper dosage instructions and consult your healthcare provider if symptoms persist.
