How does Gaviscon Double Action Liquid relieve acid reflux and indigestion?


Gaviscon Double Action Liquid contains three active ingredients that work together to relieve acid reflux and indigestion. The first two are antacids, calcium carbonate and sodium bicarbonate, which neutralise excess stomach acid, turning it into a harmless substance like water to ease stomach lining irritation. The third is sodium alginate, which forms a protective layer over stomach contents, preventing acid reflux and soothing irritation.


What causes indigestion?


Various factors can lead to indigestion and heartburn, including lifestyle choices or triggers such as certain foods, drinks, and medications. Common causes include consuming fatty, greasy, or spicy foods; overeating or eating too quickly; excessive caffeine or alcohol consumption; smoking and anxiety; and some antibiotics and pain relievers. If indigestion persists, consider dietary adjustments or consult your GP for advice.

Pregnant or breastfeeding women, those who think they might be pregnant, or planning to conceive should consult their doctor or Health Pharmacy pharmacist before using Gaviscon Double Action Liquid to ensure suitability.
