The Story
Are Rennie Peppermint Tablets Right for Your Heartburn?
If you've ever felt that familiar burning sensation creeping up your chest after a meal, you'll know how uncomfortable heartburn can be. Rennie peppermint tablets are a well-established, over-the-counter antacid that works quickly to neutralise excess stomach acid and bring relief from heartburn, acid indigestion, and an upset stomach. Each pack contains 12 tablets in a refreshing peppermint flavour, making them easy to carry and use whenever symptoms strike. You can browse our full range of indigestion treatments if you'd like to compare your options.
Heartburn is extremely common in the UK. It occurs when stomach acid travels back up into the oesophagus, causing that characteristic burning discomfort. Rennie has been trusted by millions of people for decades, and the peppermint variant offers the same reliable antacid action with a pleasant taste.
How Do Rennie Peppermint Tablets Work to Relieve Symptoms?
Rennie peppermint tablets work through a straightforward chemical process. The active ingredients — calcium carbonate and heavy magnesium carbonate — are alkalis that react directly with hydrochloric acid in the stomach. This neutralisation reaction raises the stomach's pH, reducing acidity and relieving the burning sensation quickly.
- Calcium carbonate (680 mg) reacts with stomach acid to form calcium chloride, water, and carbon dioxide
- Heavy magnesium carbonate (80 mg) provides a complementary buffering effect, helping to sustain relief
- The combined action neutralises excess acid on contact, typically within minutes
- The peppermint flavouring makes the tablet pleasant to chew or suck
Who Should Use Rennie Peppermint Tablets for Indigestion Relief?
These tablets are suitable for most adults and young people who experience occasional heartburn or indigestion. They're particularly handy after large meals, spicy food, or when you've eaten too quickly. That said, they're not a long-term solution for persistent or severe symptoms — if you're reaching for antacids more than three times a week, it's worth speaking to your GP.
- Adults aged 18 and over experiencing occasional heartburn or acid indigestion
- Young people aged 12–17 (under adult supervision)
- Pregnant women experiencing heartburn (always check with your midwife or GP first)
- People who prefer a chewable, flavoured antacid tablet over liquid formulations

How Should You Store Rennie Peppermint Tablets and Who Should Avoid Them?
Store your Rennie peppermint tablets below 25°C in a dry place, away from direct sunlight. Keep them out of reach and sight of children. Do not use them after the expiry date printed on the packaging. If you're also taking other medicines — particularly tetracycline antibiotics or iron supplements — leave at least two hours between doses, as antacids can reduce their absorption. People with kidney disease, hypercalcaemia, or those on a low-calcium diet should seek medical advice before use. If you're managing a digestive condition alongside other health concerns, you might also find our IBS and cramps range useful.
This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Rennie Peppermint Tablets 12 Pack
What Are Rennie Peppermint Tablets and What Are They Used For?
Rennie Peppermint Tablets are an over-the-counter antacid medicine used to relieve the symptoms of heartburn, acid indigestion, and an upset or sour stomach. They contain two active ingredients — calcium carbonate and heavy magnesium carbonate — which work by neutralising excess acid in the stomach. The tablets are chewable and peppermint-flavoured, making them convenient to take without water. They are classified as a General Sale List (GSL) medicine in the UK, meaning you can buy them without a prescription.
Heartburn happens when stomach acid flows back into the oesophagus, causing a burning feeling in the chest or throat. Indigestion (also called dyspepsia) can cause bloating, discomfort, or a feeling of fullness. Rennie peppermint tablets are designed to address these symptoms quickly and effectively for short-term, occasional use.
What Do You Need to Know Before Using Rennie Peppermint Tablets?
Before taking these tablets, read the following carefully. Some people should not use this product, or should only use it under medical supervision.
Do not take Rennie Peppermint Tablets if you:
- Are allergic to calcium carbonate, magnesium carbonate, or any other ingredient in the tablet
- Have hypercalcaemia (high calcium levels in the blood)
- Have severe kidney disease or kidney failure
- Are on a medically supervised low-calcium diet
Speak to your GP or pharmacist before use if you:
- Are pregnant or breastfeeding
- Have kidney problems (even mild)
- Have been told you have low phosphate levels
- Are taking other medicines regularly
Known drug interactions — leave at least 2 hours between Rennie and:
- Tetracycline antibiotics (e.g. doxycycline) — antacids reduce their absorption
- Iron supplements — calcium can inhibit iron uptake
- Some heart medicines, thyroid medicines, and bisphosphonates — timing matters
- Quinolone antibiotics (e.g. ciprofloxacin)
How Should You Use Rennie Peppermint Tablets Correctly?
Always use this medicine exactly as described in the patient information leaflet or as directed by your pharmacist. Do not exceed the stated dose.
- Chew or suck 2 tablets when symptoms occur — do not swallow them whole
- Allow the tablet to dissolve fully in your mouth before swallowing
- You may repeat the dose after a few hours if symptoms return
- Do not take more than 6 tablets in any 24-hour period
- If symptoms persist for more than 7 days, stop use and consult your GP
| Age Group | Dose | Frequency | Maximum Daily Dose |
|---|---|---|---|
| Adults and children 12+ | 2 tablets | When symptoms occur | 6 tablets (3 doses) |
| Children under 12 | Not recommended | — | — |
What Are the Possible Side Effects of Rennie Peppermint Tablets?
Like all medicines, Rennie Peppermint Tablets can cause side effects, although not everyone gets them. Most people tolerate them well when taken as directed.
Common side effects:
- Constipation (more likely with calcium carbonate)
- Diarrhoea (more likely with magnesium carbonate)
- Flatulence or belching due to carbon dioxide produced during neutralisation
Less common side effects:
- Nausea or stomach discomfort
- Hypercalcaemia (raised blood calcium) with prolonged, excessive use
- Milk-alkali syndrome — a rare condition caused by very high calcium intake alongside antacids; symptoms include nausea, vomiting, and confusion
If you experience any serious or unexpected symptoms, stop taking the tablets and seek medical advice promptly. You can also find related digestive health support in our IBS and cramps section or explore our vitamins and supplements range for general gut health support.
How Should You Store Rennie Peppermint Tablets Safely?
- Store below 25°C in a dry place
- Keep away from direct sunlight and moisture
- Keep out of the sight and reach of children
- Do not use after the expiry date printed on the pack

How do Rennie Peppermint Tablets work in the body?
Rennie peppermint tablets contain calcium carbonate and magnesium carbonate, both of which are alkalis that neutralise excess hydrochloric acid in the stomach. This chemical reaction raises the stomach's pH and relieves the burning discomfort of heartburn and indigestion. The effect is typically felt within a few minutes of chewing the tablets.
How do I use Rennie Peppermint Tablets step by step?
Chew or suck 2 tablets when your symptoms occur — do not swallow them whole. Allow the tablet to dissolve fully in your mouth before swallowing. You can repeat the dose if symptoms return, but do not take more than 6 tablets in any 24-hour period.
What is the correct dose of Rennie Peppermint Tablets for adults?
The recommended dose for adults and children aged 12 and over is 2 tablets, chewed or sucked when symptoms arise. This can be repeated up to 3 times daily, giving a maximum of 6 tablets in 24 hours. Do not exceed this dose without speaking to a pharmacist or GP.
When is the best time to take Rennie Peppermint Tablets?
Take Rennie peppermint tablets as soon as heartburn or indigestion symptoms begin — there's no need to wait. Many people find them most useful after meals, particularly after eating spicy, fatty, or rich foods. They can also be taken before bed if you experience night-time heartburn.
Can I take Rennie Peppermint Tablets during pregnancy?
Rennie tablets are generally considered suitable for occasional use during pregnancy, as heartburn is very common in the second and third trimesters. However, you should always speak to your midwife, GP, or pharmacist before taking any medicine while pregnant. They can advise on the safest option for your individual circumstances.
Are Rennie Peppermint Tablets suitable for children?
Rennie Peppermint Tablets are suitable for adults and young people aged 12 and over. They are not recommended for children under 12 without specific medical advice from a GP. If your child is experiencing persistent indigestion or stomach pain, always consult a healthcare professional.
What are the side effects of Rennie Peppermint Tablets?
Side effects are uncommon when Rennie is taken as directed, but some people may experience constipation, diarrhoea, or flatulence. Prolonged or excessive use can, in rare cases, lead to raised blood calcium levels (hypercalcaemia). If you notice any unusual or persistent symptoms, stop use and speak to your pharmacist or GP.
How do I manage side effects of Rennie Peppermint Tablets?
Most side effects, such as mild constipation or wind, resolve on their own once you stop taking the tablets or reduce your dose. Staying well hydrated can help with constipation. If side effects are persistent or severe, contact your pharmacist — they can suggest an alternative from our indigestion range.
Can Rennie Peppermint Tablets interact with other medicines?
Yes — antacids like Rennie can reduce the absorption of certain medicines if taken at the same time. These include tetracycline antibiotics, iron supplements, quinolone antibiotics, and some thyroid and heart medicines. Leave at least 2 hours between taking Rennie and any other medication to avoid this interaction.
Who should not take Rennie Peppermint Tablets?
You should not take Rennie Peppermint Tablets if you have hypercalcaemia (high blood calcium), severe kidney disease, or are on a medically supervised low-calcium diet. People with known allergies to any of the ingredients should also avoid them. Always check with your pharmacist if you are unsure whether this product is right for you.
What are alternatives to Rennie Peppermint Tablets for heartburn?
Alternatives include other antacids such as Gaviscon (which forms a protective raft over stomach contents) or Tums. For more frequent heartburn, a GP may recommend an H2 blocker or a proton pump inhibitor such as omeprazole. You can explore our full indigestion treatments collection for more options.
How long can you use Rennie Peppermint Tablets for?
Rennie Peppermint Tablets are intended for short-term, occasional use only. If you find yourself needing them more than three times a week, or if symptoms persist for more than 7 days, you should stop use and consult your GP. Persistent heartburn or indigestion may indicate an underlying condition that needs proper investigation.
What happens if I take too many Rennie Peppermint Tablets?
Taking more than the recommended dose can increase the risk of side effects, including raised blood calcium levels, nausea, and in rare cases milk-alkali syndrome. If you think you or someone else has taken too many tablets, contact NHS 111 or go to your nearest A&E. Always keep medicines out of reach of children.
What are the latest findings on antacid use for heartburn relief?
Current NHS guidance confirms that antacids containing calcium carbonate and magnesium carbonate remain a first-line option for occasional heartburn and indigestion. Lifestyle changes — such as eating smaller meals, avoiding trigger foods, and not lying down after eating — are also recommended alongside antacid use. For chronic or severe symptoms, a GP assessment is always advisable.
