Description

Gaviscon Double Action Liquid Sachets are designed to relieve the uncomfortable symptoms of acid reflux, heartburn and indigestion. Gaviscon Double Action Liquid Sachets combine acid neutralising ingredients with an alginate that forms a soothing protective layer on top of the stomach contents. This dual action helps calm burning sensations in the chest and throat while reducing further irritation. The liquid format allows for quick action and easy swallowing without the need for water.

  • Dual action formula: neutralises acid and forms a protective barrier
  • Provides relief from heartburn and acid reflux
  • Soothing liquid suspension
  • Convenient pre-measured single-use sachets

Directions

Shake Gaviscon Double Action Liquid Sachets well before opening to ensure the contents are properly mixed. Adults and children over the recommended age typically take one to two sachets after meals and at bedtime, or as directed by a healthcare professional. Squeeze the contents directly into the mouth and swallow.

Do not exceed the stated maximum daily dose and consult a doctor if symptoms persist for more than seven days.

Ingredients

Gaviscon Double Action Liquid Sachets contain sodium alginate, sodium bicarbonate and calcium carbonate as the active ingredients. Sodium bicarbonate and calcium carbonate help neutralise excess stomach acid, while sodium alginate forms a protective raft over the stomach contents.

Gaviscon Double Action Liquid Sachets also contain flavourings and other excipients to create a smooth liquid suspension. The full list of ingredients and their strengths can be found on the packaging and patient information leaflet.

Warnings

Do not use Gaviscon Double Action Liquid Sachets if you are allergic to any of the ingredients. Consult a healthcare professional before using Gaviscon Double Action Liquid Sachets if you have kidney problems, are on a low-sodium diet or are pregnant or breastfeeding.

Gaviscon Double Action Liquid Sachets contain sodium and calcium, which should be considered if you are monitoring your intake.

If symptoms worsen or do not improve after seven days, seek medical advice. Keep out of sight and reach of children.
