You can usually take 2 to 4 Gaviscon tablets up to 4 times a day , after meals and at bedtime, depending on the exact product and your age.

Quick Scoop

For most standard Gaviscon chewable tablets in adults and children 12+:

  • Typical single dose: 2–4 tablets after meals and at bedtime.
  • Usual maximum frequency: Up to 4 times a day.
  • That means a common maximum is around 16 tablets a day for many UK-style Gaviscon tablet products (4 tablets × 4 doses).
  • Some branded Canadian “Regular Strength Tablets” say 2–5 tablets up to 20 per day for adults and children 12+, with at least 2 hours between doses.

Because there are different Gaviscon versions (Regular, Double Action, Advance, different countries), the exact maximum number of tablets per day depends on the specific product and label where you live.

Things You Must Check

  • The exact product name (e.g., Gaviscon Double Action tablets, Regular Strength, Extra Strength, country-specific versions).
  • The age group (adult / child) and any conditions like kidney disease, pregnancy, or low-salt diet, which can change what’s safe.
  • The warning section : some packs advise not to exceed 5 tablets a day if you are pregnant or on a low-salt diet.

If you’ve already taken close to or above the maximum on the packet, or you’re unsure which version you have, it’s safest to:

  1. Stop taking more for now.
  2. Call a pharmacist, doctor, or local poison/medical helpline and tell them:
    • Your age and weight
    • Exact product (country, “Regular / Double Action / Advance”)
    • How many tablets you took and when

When It Can Be Risky

Taking much more than the recommended dose or using it heavily for a long time can cause problems such as:

  • Too much sodium (salt) intake, which can be an issue for high blood pressure or heart problems.
  • Issues in people with kidney disease , especially with products that contain magnesium or aluminum salts.
  • Masking more serious conditions like ulcers or heart problems if you’re using it constantly instead of getting checked.

If you have severe chest pain, pain spreading to arm/jaw, breathlessness, or sweating, call emergency services rather than taking more Gaviscon.

Bottom line

  • If you’re an adult using a typical Gaviscon chewable tablet, a reasonable rule from many labels is 2–4 tablets after meals and at bedtime, up to 4 times per day , and never more than what your own packet states.
  • If the label on your pack says something different (for example, “up to 20 tablets per day”), always follow your own package instructions first.

If you tell me:

  • The country you’re in, and
  • The exact name written on your Gaviscon box or bottle,

I can help you interpret the likely max number more specifically (still not replacing medical advice).
