Gaviscon Advance Aniseed Liquid is a specialized oral suspension designed to provide relief from heartburn and indigestion. This 300ml bottle contains sodium alginate, sodium bicarbonate, and calcium carbonate with an aniseed flavor, offering up to 4 hours of protection against acid reflux symptoms. The formula works by creating a protective barrier on top of stomach contents to prevent acid reflux. The liquid suspension contains sodium alginate which forms a raft on the stomach contents, while sodium bicarbonate and calcium carbonate help neutralize excess stomach acid. The aniseed flavor makes the medication more palatable. The 300ml bottle comes with a measuring cap for accurate dosing. As with all medications, follow the recommended dosage instructions and consult a healthcare professional if symptoms persist.
