Hey I’m traveling in Thailand, I recently had travellers diarrhoea, I took a 5 day course of Ciprofloxacin which cured it for a week then it came back so I took 3 days of ciprofloxacin. Again it cured for a week, but now it’s back again. Symptoms are mild mostly after I eat, I’m often fine in the morning then sick after I eat in the afternoon, I’m also burping more often. Is it okay to take a single 2gram dose of trinidazole to kill any Giardia or ameobiasis? Thanks
