I have diverticulitus, and have had diareaha for the last
Imodium 4mg thrice daily. Low doses won't help.
Thanks for choosing 'Ask a doctor' service for your query.
As you are concerned about the treatment:
Continue taking the tablet Imodium 4mg thrice daily to stop loose watery stools.
As diverticulitis is caused by bacteria as well as protozoa take any broad-spectrum antibiotic like Ciprofloxacin 500 mg three times a day to cover bacteria and Metronidazole 400mg three times a day to cover protozoal infection. These are prescription based medications.
However, in case you can't get a prescription just take Imodium 4mg thrice daily to stop loose motions(it's over the counter).
Along with it take a probiotic like Econorn twice daily and add fiber supplements to the diet.
Let me know if I can assist you further.
