Treatments and drugs
By Mayo Clinic staff
Because traveler's diarrhea tends to resolve itself, you may get better without any intervention. It's important to try to stay hydrated with safe liquids, such as bottled water or canned juice. If you don't seem to be improving quickly, you can turn to several medications to help relieve symptoms.
Anti-motility agents. These agents — which include loperamide (Imodium A-D), medications containing diphenoxylate (Lomotil), and opiates, such as paregoric and codeine — provide prompt but temporary relief by reducing muscle spasms in your gastrointestinal tract, slowing the transit time through your digestive system and allowing more time for absorption. They aren't recommended for infants or people with fever or bloody diarrhea, as they can delay clearance of the infectious organisms and make the illness worse. Also, stop using anti-motility agents after 48 hours if you have abdominal pain or your signs or symptoms worsen and your diarrhea continues. In such cases, see a doctor.
Bismuth subsalicylate (Pepto-Bismol). This over-the-counter medication can decrease the frequency of your stools and shorten the duration of your illness. However, it isn't recommended for children, pregnant women or people who are allergic to aspirin.
Antibiotics. If you have severe symptoms or three or more loose stools within eight hours, a doctor may prescribe a three- to five-day course of antibiotics.
Before you leave for your trip, talk to your doctor about appropriate medications to take with you so that you don't have to buy diarrhea medications while traveling. Some of the drugs available in other countries may be unsafe. Some may even have been banned in the United States.
