In short
- Pepto-Bismol contains bismuth subsalicylate. In Spanish, that is subsalicilato de bismuto.
- We found no product with this ingredient on CIMA, the Spanish medicines database. Ask a pharmacist what is sold here.
- Gastrodenol contains a different bismuth salt and is used for Helicobacter pylori. It does not replace Pepto-Bismol.
- The NHS says not to take Pepto-Bismol while pregnant or breastfeeding. Ask a doctor first before giving it to a child.
What is Pepto-Bismol called in Spain?
Pepto-Bismol is a brand name used in the US and the UK. The NHS also lists Pepti-Calm as a UK brand. The ingredient in both is bismuth subsalicylate. In Spanish, it is called subsalicilato de bismuto.
We searched CIMA, the database run by the Spanish medicines agency (AEMPS). It listed no product with this ingredient. So we cannot point you to a direct Spanish equivalent. The list can change, so a pharmacist can check what is available now.
CIMA does list a different bismuth salt, bismuth subcitrate (subcitrato de bismuto). One example is Gastrodenol. Its leaflet says it acts on Helicobacter pylori, a germ linked to gastritis and stomach ulcers. It is not a Pepto-Bismol swap. It is not meant for a holiday upset stomach.
Do you need a prescription for bismuth subsalicylate in Spain?
We have no reviewed prescription status for this ingredient in Spain. CIMA lists no authorised product, so there may be nothing to buy, with or without a prescription. Check with a pharmacist. They can tell you what is sold in Spain for your symptoms. For diarrhoea, oral rehydration solution (suero de rehidratación oral) is often the first step. Our guide to medicines in Spain explains how Spanish pharmacies work.
What is bismuth subsalicylate used for?
The NHS says Pepto-Bismol treats the symptoms of indigestion, heartburn and diarrhoea. It usually comes as a liquid or as chewable tablets. You can take it with or without food. In the US, it is also sold for travellers' diarrhoea.
It can turn your tongue or stools black. This is harmless and goes away after you stop taking it. It can also make bleeding from the gut harder to spot. Keep that in mind if you feel unwell.
Who should not take bismuth subsalicylate?
Bismuth subsalicylate is a salicylate, which makes it a relative of aspirin. The NHS says most people aged 16 and over can take it. It also says not to take it if you are pregnant or breastfeeding. Tell a doctor or pharmacist first if you:
- Have ever reacted badly to aspirin or any other medicine.
- Have diabetes or gout.
- Have a blood clotting disorder or a stomach ulcer.
- Have phenylketonuria. The chewable tablets contain aspartame.
The NHS also warns that some medicines do not mix with it. These include aspirin, blood thinners (anticoagulants), some antidepressants, and some gout and diabetes medicines. Do not take it with other bismuth medicines, such as Gastrodenol.
Age rules differ by country. US labels allow it from age 12, but the NHS says 16. In children and teenagers with chickenpox or flu, salicylates carry a risk of Reye's syndrome. This rare illness harms the brain and liver. If your child has diarrhoea, ask a doctor or pharmacist first.
When should you see a doctor about diarrhoea?
Most diarrhoea clears up on its own. Drink plenty of fluids. See a doctor today if:
- There is blood or mucus in your stools.
- You have a high fever or bad belly pain.
- You cannot keep fluids down, or you pass very little urine.
- It lasts more than a few days, or keeps getting worse.
- You are pregnant, older, or have a long-term illness.
- A baby or young child has diarrhoea or vomiting and seems unwell.
Our travellers' diarrhoea page explains how a video visit can help. Call 112 if you vomit blood, faint, or feel very drowsy or confused.
Can a UK or US prescription be used in Spain?
In practice, no. Spanish pharmacies refuse prescriptions from the UK, the US and other countries. For a prescription medicine, a doctor licensed in Spain has to issue a Spanish private electronic prescription. Still, no prescription can make a product available if it is not authorised in Spain.
If you brought Pepto-Bismol from home, read its label and leaflet before using it. Check the warnings above too.
Frequently asked questions
Can I buy Pepto-Bismol in Spain?
Not under that name. We found no bismuth subsalicylate product on CIMA, the Spanish medicines database. Ask a pharmacist what is sold in Spain for your symptoms.
Is Gastrodenol the same as Pepto-Bismol?
No. Gastrodenol contains bismuth subcitrate, a different bismuth salt. Its CIMA leaflet says it acts on Helicobacter pylori, linked to gastritis and ulcers. It is not meant for an upset stomach.
Why did my tongue or stools turn black?
Bismuth can turn the tongue and stools black. This is harmless and goes away after you stop. If you also feel faint or dizzy, get medical help.

The NHS says not to take Pepto-Bismol while pregnant or breastfeeding. Ask a doctor what is safe for diarrhoea or heartburn in pregnancy.
