Do you have indigestion? Do you have diarrhea? Learn what medicines will help you fight these illnesses in Lima, Peru and continue enjoying your trip.

Two of the most common illnesses affecting tourists and visitors to Lima, Peru are Traveler’s Diarrhea, caused by E. coli, Shigella and Salmonella, and bloating caused by the excess gas in the stomach or intestinal track accompanied by constipation and stomach or abdominal pains.

Drinking contaminated water (including ice) and eating new dishes full of new spices can contribute to ruin your vacation. Adults should be able to handle this kind of infection and recover after a few days but that is not sufficient when you only have few days to visit, relax and enjoy Peru.

Familiar medicine found in CVS or Walgreens (both in the US) like Maalox, Gas-X, Imodium, Mylanta, Rolaids to name a few, might be hard to find in Lima, but alternatives under a different name are available.

10 Things to know about Pharmacies in Lima, Peru

Fake and expired medicines are sold every day in Peru mostly to people with lower income looking for a good deal. So please, be careful when purchasing or accepting medicine. Ask for the origin of the medicine andor the name of the pharmacy where the medicine was purchased. Remember that if the price just seems incredible low, you are probably looking into a fake medicine, or expired medicine. Don’t take any risks.

Natural Remedies

Thanks to Dr. Axe for this beautiful infographic. In Peru, you can find many of these foods, like:

  • Bone Broth: Most likely as an ingredient for a soup.
  • Probiotic Foods (check the best supermarkets: 5 Supermarkets to Buy your Groceries in Lima, Peru)
  • Oats (“Aven” in Spanish): You can find in most markets.
  • Bananas (“Platanos” in Spanish): You can find platanos even on some small markets. Very popular.
  • Vegetable Juice: There are many good juice restaurants in Lima, Peru.
  • Sweet Potatoes (“Camotes” in Spanish): Tricky to get those ready-to-eat unless you are in a restaurant or your apartment has a full kitchen.
  • Flaxseed Oil (“Aceite de Linaza” in Spanish): Some stores should carry this type of oil.
  • Ginger (“Jengibre” in Spanish): Very popular. Should find it in any grocery stores or as a popular ingredient in a juice bar.
  • Water (“Agua sin Gas” in Spanish): Don’t be crazy and drink from the kitchen faucet. Just buy some water bottles (lots of them)
  • Peppermint Oil (“Aceite de Menta” in Spanish): Somewhat popular.


Best Advice Ever

If you are carrying a backpack, please ALWAYS carry with you a roll of toilet paper. Many restaurants (and in public restrooms) will let you access their facilities, but many (depending the location) will not have toilet paper in their restrooms. I know, I know… is crazy, but they have to curbed their misuse somehow. Just do yourself a favor and carry toilet paper just for those emergencies.

  1. I was given Buscapina in Uruguay after contracting a nasty stomach bug in Argentina. The stuff tastes AWFUL however it is a Godsend! Saved me! I will definitely stock up when I’m travel again. In Montevideo, you do not need a prescription. Like most LA and SA countries, they don’t sell Pepto or other type of products.

    1. Yes, buscapina has a nasty flavor but it is very effective and quick. Don’t trust you will find the same medicines (like Pepto) everywhere you travel. Good point. Thanks for your comment HLJ.

  2. Hi there, I’m a peruvian living abroad for many years and have found that traveling back to my own country has been a pain in the butt (no pun intended!). I can’t seem to make a trip there without some sort of stomach/intestinal problem. Your article has been a life saver. Muchas gracias!!!

    1. I am so glad this article helped so many. I wrote because I found myself in the same predicament. Peruvian food is one of the best, no doubt, but your stomach needs preparation to handle all the spices. Thanks for your comment Veronica.

  3. This case in so handy thank you! I don’t have a problem using the restroom but every time I ate something my stomach cramped and hurt very badly and I became bloated.
