Take Gaviscon Advance Liquid Sachets after meals and before bedtime, as this is when reflux symptoms are most likely to occur. Tear open the sachet along the marked edge and swallow the entire contents directly; there is no need to take it with water, mix it, or dilute it, although a small sip of water afterwards is not harmful.

Do not take this product at the same time as other antacid, alginate, or reflux medicines unless advised by a pharmacist or doctor, as combining products with the same or overlapping active ingredients can lead to excess intake of sodium, potassium, or calcium. If you are taking other oral medicines, leave a gap of at least 2 hours before or after taking Gaviscon Advance (see Drug/Food Interactions).

The typical adult and adolescent (12 years and above) dose is 1 to 2 sachets (10ml to 20ml), taken after meals and again at bedtime. This may be repeated up to four times in 24 hours, depending on symptoms. Each sachet is a single pre-measured dose and can be taken directly without needing to dilute it with water.

If a dose is missed, simply take the next dose when needed for symptoms — Gaviscon Advance is normally used as required rather than on a strict fixed schedule, so there is no need to double up. If heartburn or reflux symptoms do not improve after 7 days of regular use, or if they return frequently, stop self-treating and consult a doctor or pharmacist, as this may indicate a condition that needs further assessment. Use in children under 12 years should only be under medical advice.

Use before the expiry date printed on the packaging. As each sachet is intended for single use, use the entire contents at the time of opening and discard the empty sachet; do not store a partially used sachet for later use.

Store below 25°C in a cool, dry place away from direct sunlight and moisture. Keep the sachets in their original carton until ready to use, and keep out of the sight and reach of children. Do not use if a sachet is damaged, punctured, or leaking.

• Common: Mild bloating or a feeling of fullness after use.
• Common: Occasional flatulence (trapped wind).
• Common: Mild nausea or a change in bowel habit, such as diarrhoea, particularly with frequent use.
• Serious: Rare allergic reactions, including skin rash, itching, swelling of the face, lips, or throat, or difficulty breathing (which may indicate anaphylaxis or bronchospasm) — stop use and seek immediate medical attention if this occurs.

• Known hypersensitivity (allergy) to sodium alginate, potassium bicarbonate, calcium carbonate, or any other ingredient in the formulation, including the preservatives methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216).
• Not recommended without medical advice in patients with severely impaired chronic health condition or those on a potassium-restricted diet, due to the potassium bicarbonate content.
• Use with caution in patients with hypercalcaemia (high blood calcium) or a history of chronic mineral-related conditions, due to the calcium carbonate content.

• Gaviscon Advance can reduce the absorption of other medicines taken by mouth if they are taken too close together, because the alginate raft and its calcium/potassium content can interfere with how other drugs are absorbed in the stomach.
• This effect has been specifically noted with medicines such as tetracycline and quinolone antibiotics, iron supplements, thyroid hormone replacement (e.g. levothyroxine), digoxin, chloroquine, and bisphosphonates.
• As a general precaution, leave a gap of at least 2 hours between taking Gaviscon Advance and any other oral medicine.
• Avoid taking it together with other antacid or alginate-containing products to prevent excessive intake of sodium, potassium, or calcium.
• If you take regular prescription medicine, check with your pharmacist or doctor before starting Gaviscon Advance.

• Take a sachet after meals and again before bed — this is when reflux is most likely to happen.
• No water needed — the liquid can be swallowed straight from the sachet.
• Keep other oral medicines at least 2 hours apart from your Gaviscon Advance dose.
• Don’t double up with other antacids or reflux products at the same time.
• Carry a sachet in your bag when eating out, travelling, or at work for on-the-go relief.
• If you’re reaching for it most days of the week, check in with a pharmacist — frequent reflux may need a closer look.

Precautions: Gaviscon Advance is generally considered suitable for use during pregnancy and breastfeeding when taken as directed, but pregnant or breastfeeding women should still check with a doctor or pharmacist before use. Caution is advised in people with significant a significant chronic health condition, as the potassium content may not be suitable for those who need to restrict their potassium intake. Each sachet also contains sodium, a consideration for individuals on a medically supervised low-sodium diet (such as those with certain serious chronic health conditions), and calcium, which those with hypercalcaemia or a history of chronic mineral-related conditions should be aware of.

When to See a Doctor or Pharmacist: Speak to a doctor or pharmacist if heartburn or reflux symptoms persist for more than about 2 weeks despite regular use, if symptoms are severe or keep coming back, or if you experience difficulty or pain when swallowing, unexplained weight loss, persistent vomiting, or blood in vomit or stools. These can be signs of a condition that needs further medical assessment rather than ongoing self-treatment.
