Important information about Gaviscon Liquid
The active ingredient in Gaviscon Liquid is a combination of sodium alginate, aluminum hydroxide, and magnesium carbonate, which work together to relieve acid reflux symptoms. Aluminum hydroxide and magnesium carbonate act as antacids, helping to neutralize excess stomach acid. This reduces the burning sensation linked to heartburn.
Sodium alginate creates a foam-like layer that floats on top of stomach contents. This barrier helps prevent acid from moving back up into the esophagus, offering additional relief.
Some formulations also include simethicone, which can help reduce gas. Inactive ingredients such as xanthan gum, glycerin, sorbitol solution, benzyl alcohol, edetate disodium, and saccharin sodium help improve the taste, texture, and stability of the liquid. This dual-action approach makes it a fast-acting option for managing symptoms.
Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Gaviscon. However, the following is a synopsis of the general guidelines for the use of Gaviscon:
- Always shake well before each use to ensure the ingredients are evenly mixed.
- Measure the dose using a proper measuring device, not a household spoon. Doses are usually taken in teaspoonfuls after meals and at bedtime, depending on the product and whether it is extra strength.
Some mild or common side effects of Gaviscon include:
- Mild constipation from aluminum hydroxide
- Possible laxative effect from magnesium carbonate
- Bloating or gas
- Chalky or unusual taste
Some individuals may experience serious side effects while using Gaviscon. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:
- Signs of an allergic reaction, such as rash, swelling, or trouble breathing
- Severe stomach pain
- Persistent vomiting
- Symptoms of electrolyte imbalance
These are not all of the possible side effects of Gaviscon. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.
Before starting Gaviscon, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including if you have:
- Kidney disease
- A sodium-restricted diet
- A magnesium-restricted diet
- Frequent or severe acid reflux
- Ongoing digestive issues
Some liquid antacid products contain sodium and magnesium, which may not be suitable for certain individuals. Long-term use without medical advice is not recommended. If symptoms such as acid reflux or upset stomach persist, further evaluation may be needed.
Gaviscon Liquid should not be used in individuals who:
- Have a known allergy to any of its ingredients
- Have severe kidney disease without medical supervision
- Require strict avoidance of sodium or magnesium
Always consult your healthcare provider if you are unsure whether this product is appropriate for you.

When Gaviscon is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:
- Other antacid products
- Certain antibiotics
- Thyroid medications
- Iron supplements
Spacing doses may be necessary to prevent reduced absorption of other medications.
Gaviscon Liquid is available in different strengths, including standard and extra strength formulations.
