How is traveler's diarrhea treated?
Even if you don't treat traveler's diarrhea, it will usually go away in 4 to 5 days. You should drink plenty of clear liquids to replace lost fluids due to the diarrhea. Taking medicine to treat traveler's diarrhea may make you feel better more quickly. It often is treated with antibiotics (medicines that kill bacteria). To get antibiotics, you need a prescription from your doctor.
You also can take a medicine called loperamide (brand name: Imodium). However, if you have bloody diarrhea, you should not take this medicine without also taking an antibiotic.
