Hi , I'm sorry to hear you are no longer finding relief with your current medication. I do know that the most common anti-diarrheal is the one you're currently taking, loperamide, also known as Imodium. Some other forms of anti-diarrheals, such as diphenoxylate/atropine (Lomotil), are only available with a prescription. If you haven't brought your current treatment concerns up to your doctor yet, I would definitely recommend doing so. Here is some further information regarding anti-diarrheals and treatment in general. https://inflammatoryboweldisease.net/treatment/symptom-management/anti-diarrheals/
I hope you find a new treatment plan that works for you soon! Please keep us updated, if you can. We're here for you! - Pam (team member)
