There is no such thing as “which antivirals to take for diarrhea”, because it is not necessary to use antiviral drugs to treat diarrhea symptoms, only viral infections caused by diarrhea are considered to use antiviral drugs. Diarrhea can be caused by inflammatory bowel disease, intestinal flora imbalance and other conditions. Inflammatory bowel disease can be treated with prednisone to control inflammation, as well as mesalazine and infliximab as prescribed by the doctor. Surgery is needed in case of intestinal hemorrhage or perforation. Diarrhea caused by intestinal flora imbalance can be treated with Saccharomyces boulardii, and montelukast can be used to stop diarrhea when the diarrhea is severe. Antiviral drugs are not usually indicated in the above cases, so there is no such thing as “which antiviral drugs to take for diarrhea”. Viral infection of the gastrointestinal tract leading to acute gastroenteritis can be supplemented with antiviral drugs such as ribavirin, but most of them are still symptomatic treatment, such as rehydration. When you have diarrhea symptoms, you can go to the hospital, under the guidance of the doctor’s medication, should not blindly use drugs to treat.
