Dosage instructions vary by product and are provided on the packaging. It is essential to follow the recommended dose and not exceed the maximum daily amount.

Usage

Gaviscon is a non-prescription medication used for the relief of symptoms associated with acid reflux and indigestion, including:
• Acid Indigestion: An uncomfortable feeling in the stomach or chest, often after eating.
• Heartburn: A burning sensation in the chest or throat.
• Sour Stomach: A sour or bitter taste in the mouth.

Mechanism of Action
Unlike traditional antacids that neutralize stomach acid, Gaviscon works in a unique way to prevent heartburn. The primary active ingredient in Gaviscon is sodium alginate, which is derived from brown seaweed. Upon ingestion, it reacts with stomach acid to form a viscous gel, often referred to as a "raft," that floats on top of the stomach contents. Other ingredients, such as sodium bicarbonate, react with stomach acid to produce carbon dioxide gas. This gas gets trapped in the gel, helping the raft to float to the surface. This floating barrier acts as a physical shield, stopping stomach acid from splashing up into your esophagus and causing heartburn. Ingredients like calcium carbonate and magnesium carbonate also work as traditional antacids by neutralizing stomach acid to relieve existing symptoms. Because it both neutralizes acid and creates a protective barrier, Gaviscon provides fast, long-lasting relief from heartburn.

Take Gaviscon exactly as directed on the product label. Consult a pharmacist or doctor for personalized guidance and safe use. For more information, visit the Details for: Gaviscon Heartburn Relief Tablets | Drug and Health Products Portal at https://dhpp.hpfb-dgpsa.ca/dhpp/resource/20007.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before taking Gaviscon, it is essential to discuss all possible side effects, risks, and interactions with a healthcare professional, such as a doctor or pharmacist.

Side Effects

The information below is a partial list of side effects; individual reactions can vary. Most people who take Gaviscon do not experience side effects.

Common Side Effects - The following are some common side effects of Gaviscon; other side effects may also occur. Contact a doctor or pharmacist if any side effects persist, worsen, or are concerning.
• A foaming sensation in the mouth or throat is a regular part of the mechanism of action.
• Diarrhea (more likely with products containing magnesium).
• Nausea.
• White-colored stool (due to the presence of aluminum or calcium).

Serious Side Effects - These are rare but potentially severe side effects. Seek immediate medical attention or call emergency services if you experience any of the following:
• Allergic reactions: Severe rash, hives, swelling of the face, lips, tongue, or throat, and difficulty breathing.

Contraindications

The following is not an exhaustive list of contraindications. Before taking Gaviscon, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

Gaviscon may not be suitable for some people. Check with a doctor or pharmacist before starting it if you have:
• A history of allergic reaction to any of the ingredients in Gaviscon.
• A rare, inherited illness called phenylketonuria (some products may contain aspartame).
• Age-related Concerns: Elderly individuals may be more susceptible to the risks associated with kidney dysfunction, high sodium intake, and chronic constipation.
• Cardiovascular Conditions: Heart disease or high blood pressure, as some formulations contain high levels of sodium, which can be a concern for individuals on a low-sodium diet.
• Hypercalcemia (high blood calcium levels) or a history of calcium-containing kidney stones, as some products contain calcium carbonate.
• Kidney Disease or Dialysis: Products containing aluminum can accumulate in individuals with kidney impairment and should be avoided. Chronic use of aluminum-containing products can also lead to low blood phosphate levels.

Drug Interactions

Before taking Gaviscon, it is essential to discuss all potential risks and interactions with your doctor or pharmacist to ensure a safe and effective use. For complete and up-to-date information, please visit the official Gaviscon website at https://www.gaviscon.com/products/tablets.html.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, and herbal supplements. Gaviscon may interact with other medicines by affecting their absorption. As a general rule, it's recommended to avoid taking Gaviscon within 2 hours before or after taking other medications. Gaviscon may interact with, but is not limited to:
• Antibiotics: Especially fluoroquinolones (e.g., ciprofloxacin) and tetracyclines (e.g., doxycycline).
• Bisphosphonates: (for osteoporosis, e.g., alendronic acid).
• Certain heart medications: (e.g., beta-blockers, digoxin).
• Iron supplements.
• Thyroid hormones: (e.g., levothyroxine).

Pregnancy and Breastfeeding

You can take most types of Gaviscon during pregnancy and while breastfeeding. The active ingredients are minimally absorbed into the bloodstream, making it a generally safe option. However, some ingredients (e.g., sodium, calcium) are absorbed, so it is essential to follow the instructions and not exceed the recommended amount, especially for individuals on a low-sodium diet. Always consult your doctor or pharmacist before taking any medication during pregnancy or while breastfeeding.

Use in the Elderly

There are no specific age-related warnings for Gaviscon. However, due to the increased likelihood of underlying health conditions in elderly patients, it is essential to consult a doctor or pharmacist before use, especially if they have:
• A history of high blood pressure.
• A medically prescribed low-sodium diet.
• Kidney, liver, or heart disease.

Use in Children

Gaviscon is typically not recommended for children under 12 unless it has been prescribed or recommended by a doctor. The dosage for children aged 6 to 12 is lower than that for adults.

Always consult a doctor or pharmacist for advice before giving Gaviscon to a child.
