Take Gaviscon tablets with water, usually two tablets at a time, either chewed or swallowed whole

Gaviscon tablets work by forming a protective layer over stomach acid rather than neutralizing it, so the way you take them matters. The standard dose is two tablets, taken after meals and before bed, or whenever heartburn or indigestion starts. You can chew them or swallow them whole — both work equally well. Always take them with a glass of water to help them reach your stomach and form that protective barrier.

Do not take more than eight tablets in 24 hours unless a doctor tells you to. If you are taking other medicines, space Gaviscon at least two hours away from them, because the tablet can interfere with how your body absorbs certain drugs. If your symptoms do not improve after two weeks of regular use, or if you have severe pain, see a doctor rather than taking more tablets.

Key Takeaways

  • The standard dose is two tablets chewed or swallowed with water, taken after meals or when heartburn starts.
  • Do not exceed eight tablets in 24 hours without medical information.
  • Space Gaviscon at least two hours away from other medicines to avoid interference with absorption.
  • If symptoms persist beyond two weeks, contact a doctor rather than increasing your dose.
  • Gaviscon works by coating stomach acid, not neutralizing it, so taking it with water helps it work properly.

When to take Gaviscon tablets during the day

The best time to take Gaviscon is right after you eat, because that is when food and acid move into your stomach and trigger heartburn. If you know certain foods cause problems — spicy meals, fatty foods, chocolate, caffeine — take a dose within 30 minutes of finishing eating. You can also take it before bed if you get heartburn when lying down, which is common at night.

If heartburn strikes between meals, you can take Gaviscon then too. The tablets start working within a few minutes and the effect lasts roughly three hours. If you need relief more than four times a day, that is a sign to see a doctor, because frequent heartburn may point to a condition that needs different treatment.

How to take Gaviscon if you have difficulty swallowing

Gaviscon tablets are designed to be chewed, and chewing them actually helps them work better because it breaks them down and mixes them with saliva before they reach your stomach. If you find swallowing whole tablets difficult, chewing is the easier route — the taste is mild and slightly minty. Chew them thoroughly until they are mostly dissolved, then swallow with water.

If you cannot chew tablets at all, ask your pharmacist whether a liquid Gaviscon suspension would work better for you. The liquid form works the same way but does not require chewing. Do not crush or grind Gaviscon tablets to mix with food or drink, because that changes how the medicine forms its protective layer.

Spacing Gaviscon with other medicines

Gaviscon can reduce how well your body absorbs certain medicines, so timing matters if you take other drugs. Leave at least two hours between taking Gaviscon and taking any other medicine — either take Gaviscon first and wait two hours, or take your other medicine first and wait two hours before Gaviscon. This applies to prescription medicines, over-the-counter drugs, and supplements.

Some medicines that are commonly affected include iron supplements, certain antibiotics, bisphosphonates (used for bone health), and some heart medicines. If you take any regular medication, mention Gaviscon to your pharmacist or doctor so they can tell you the safest spacing. If you are unsure, ask your pharmacist before you start taking Gaviscon regularly.

Signs that Gaviscon is not working or you need to see a doctor

Gaviscon works well for occasional heartburn, but if you are taking it more than twice a week or it is not relieving your symptoms after two weeks, something else may be going on. Persistent heartburn can signal acid reflux disease, a hiatal hernia, or other conditions that need a doctor's diagnosis. Do not keep increasing your dose — that is a sign to get medical information instead.

See a doctor right away if you have chest pain, difficulty swallowing that is getting worse, vomiting blood, or black stools. These are not straightforward heartburn and need urgent attention. Also contact a doctor if you have heartburn along with unexplained weight loss, because that combination can point to something that needs investigation.

What to do if you forget a dose or take too much

Gaviscon is taken as needed rather than on a fixed schedule, so if you forget a dose, straightforward take it when you next have heartburn. Do not double up on tablets to make up for a missed dose. If you accidentally take more than eight tablets in 24 hours, it is unlikely to cause serious harm, but contact your pharmacist or poison control if you are worried.

Taking too much Gaviscon may cause constipation or other digestive upset, but the main risk is that it will interfere with other medicines you are taking. If you regularly find yourself needing more than the recommended dose, that is a reason to see a doctor rather than keep increasing how much you take.

Storing and checking your Gaviscon tablets

Keep Gaviscon tablets in a cool, dry place — not in a bathroom cabinet where moisture can damage them. Check the expiry date on the box before you take them; expired tablets may not work as well. Store them in their original container so you can always see the instructions and the expiry date.

If your tablets look discoloured, smell unusual, or have changed texture, do not take them. Bring old or damaged tablets to a pharmacy for safe disposal rather than throwing them in the bin or flushing them down the toilet.

Frequently Asked Questions

Can I take Gaviscon with food?

Yes, and in fact taking Gaviscon after eating is the most common time to use it. Food in your stomach triggers heartburn, so taking Gaviscon within 30 minutes of finishing a meal is often the most effective approach. You do not need to wait for your stomach to be empty.

Is it safe to take Gaviscon every day?

Gaviscon is safe for occasional use, but if you need it every day, see a doctor. Daily heartburn suggests a condition like acid reflux disease that may need different treatment or investigation. A doctor can work out whether daily Gaviscon is right for you or whether something else would help more.

Can I take Gaviscon with paracetamol or ibuprofen?

Yes, but space them two hours apart. Take your painkiller first, wait two hours, then take Gaviscon — or take Gaviscon first and wait two hours before the painkiller. This prevents Gaviscon from interfering with how your body absorbs the pain relief.

What should I do if Gaviscon makes me constipated?

Gaviscon can cause constipation in some people because of its ingredients. If this happens, drink more water and eat more fibre-rich foods like fruit and vegetables. If constipation is severe or does not improve, stop taking Gaviscon and see a doctor, who may suggest a different heartburn remedy.

Can I take Gaviscon if I am pregnant?

Gaviscon is often considered safe in pregnancy because it works locally in the stomach rather than entering the bloodstream in large amounts. However, always check with your midwife or doctor before taking any medicine during pregnancy, as they know your full medical history and can advise what is safest for you.
