Digestive Relief

Digestive Relief brings together over-the-counter antacids and stomach remedies with digestive enzyme supplements: Pepto Bismol liquids, caplets and chewables, Pepto Kids, Tums Extra Strength, Nature's Answer Bubble-B-Gone, Boiron Nux Vomica and Gasalia, and NOW Super Enzymes and OstroVit Digezyme tablets. Read each label to see which type you are buying.

What is in each type

  • Calcium carbonate antacids: Tums Extra Strength are chewable tablets with more calcium carbonate per tablet than classic Tums. The US label lists heartburn, sour stomach and acid indigestion.
  • Bismuth subsalicylate: Pepto Bismol comes as Original Liquid, Ultra and Max-Strength liquids, Original caplets, Ultra caplets and cherry chews. Liquid strengths differ, so check the dose on each bottle.
  • Pepto Kids: a separate children's chewable. Check its active ingredient and age range on the pack.
  • Digestive enzymes: NOW Super Enzymes and OstroVit Digezyme are food supplements taken with meals, not medicines.
  • Homeopathic and herbal: Boiron Nux Vomica 30C and Gasalia, and Nature's Answer Bubble-B-Gone drops. See our Homeopathy range for more Boiron products.

Using over-the-counter remedies safely

Tums and Pepto Bismol are medicines with US labelling. Use them only as the label and leaflet direct, and never exceed the maximum number of doses in 24 hours. Pepto Bismol contains a salicylate, so read the warnings if you are allergic to aspirin or take blood thinners, and adult Pepto Bismol products are labelled for ages 12 and over.

Ask a pharmacist before use if you are pregnant or breastfeeding, take regular medication or have kidney problems. If you find you need an antacid most days, or symptoms last more than a couple of weeks, see your GP rather than continuing to self-treat.

For probiotics, sodium butyrate and greens powders, browse the wider Gut Health & Digestion range.

Digestive Relief: your questions answered

What is the difference between Tums and Pepto Bismol?

Tums are calcium carbonate antacids, while Pepto Bismol contains bismuth subsalicylate. Their labels list different uses, so read both, or ask a pharmacist which suits you.

Can children take Pepto Bismol?

Adult Pepto Bismol products are labelled for adults and children aged 12 and over. Pepto Kids is a separate product for younger children; follow the age range on its pack and ask a pharmacist if unsure.

Are digestive enzymes the same as antacids?

No. Enzyme supplements such as NOW Super Enzymes are food supplements containing enzymes taken with meals, while antacids are medicines that act on stomach acid.

Can I take antacids while pregnant?

Ask your pharmacist or midwife before taking any antacid or stomach remedy in pregnancy. Some ingredients, including salicylates, are not suitable.

How often can I take Tums?

Only up to the maximum daily number stated on the label. If you need antacids regularly for more than two weeks, speak to your GP.
