What is Gaviscon Double Action Liquid? 

Gaviscon Double Action Liquid is an all in one remedy for both indigestion and heartburn. This medicine works for up to four hours, helping to ease indigestion and symptoms like wind and bloating. If you’re suffering from indigestion or acid reflux and need a way to ease your symptoms after every meal or at bedtime, Gaviscon Double Action Liquid can help. Available in original aniseed, peppermint and mixed berry flavour.

What is the recommended dosage?

Always take Gaviscon Double Action Liquid exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. Shake the bottle before use. Take 10-20ml (the equivalent of 2 to 4 5ml spoonfuls) up to 4 times per day. Do not take more than 80ml of this medication per day.

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 work to neutralise excess stomach acid and turn it into a harmless substance like water to ease the irritation of your stomach lining. The third is sodium alginate, which works by forming a protective layer over your stomach contents, helping to prevent acid reflux and ease irritation all in one.

What causes indigestion? 

There are various reasons why you might be suffering from indigestion and heartburn, like lifestyle choices, or it might be triggered by certain food, drink, and medication. The most common reasons are the result of eating fatty, greasy, or spicy foods; overeating or eating your food too fast; consuming too much caffeine or alcohol; smoking and anxiety, and some antibiotics and pain relievers. If you keep getting indigestion, you might be consuming the wrong things that trigger your indigestion - try altering your diet and see if it improves, if not, speak to your GP for advice.

Is Gaviscon Double Action Liquid suitable for pregnant and breastfeeding women? 

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, you must ask your doctor or Chemist4U pharmacist for advice before taking Gaviscon Double Action Liquid to ensure it’s the right product for you.
