Pepto Bismol (bismuth subsalicylate)

Walk into a French pharmacy and ask for Pepto Bismol, and the pharmacist will most likely shake their head. The pink American remedy is not part of the French market, and its active ingredient, bismuth subsalicylate, sits in a family of drugs that France has handled with unusual care for about 50 years.

Why France is so careful with bismuth

In the 1970s, French doctors recorded hundreds of cases of bismuth encephalopathy, a rare toxic reaction that caused confusion, tremors and trouble walking. Most patients had taken large doses of older bismuth salts for long periods, and most recovered once they stopped. The episode still shapes French policy: when the ulcer treatment Pylera, which contains bismuth, was approved, France’s medicines agency (ANSM) asked doctors to watch closely for any sign of nerve problems.

What French pharmacies offer instead

In France, almost every medicine is sold in a pharmacy (look for the green cross), and pharmacists are used to giving advice at the counter. Instead of one all-in-one remedy, they match the product to the symptom:

• Diarrhea: Smecta (diosmectite clay) is the classic French choice, and loperamide (Imodium) is also common.
• Heartburn or indigestion: Gaviscon and other antacids are easy to find.
• Dehydration: oral rehydration salts.

Useful phrases at a French pharmacy

• J’ai la diarrhée (I have diarrhea)
• J’ai des brûlures d’estomac (I have heartburn)
• J’ai mal au ventre (I have a stomach ache)
• C’est pour un enfant (It’s for a child), important, since some remedies are not suitable for young children

Can you bring your own Pepto Bismol to France?

Travelers generally bring small amounts for personal use without trouble. Keep it in the original box, pack only what your trip needs, and check current rules before you fly. If you take blood thinners or are allergic to aspirin, talk to a doctor first, because the salicylate in Pepto Bismol can interact with them.

The rules are looser just across the Channel, where the UK put Pepto-Bismol back on shelves in 2025. For the full Europe-wide picture, see how Pepto Bismol’s status differs from France to the UK and beyond, or browse everything else France bans or restricts.
