Have you considered asking your physician about prescribing another form instead of a pill? For example, the active ingredient in Pentasa is mesalamine. I take mesalamine in suppository form. Its name is Canasa. I wrote an article about my experience with it in 2022. Here's the link if you'd like to read it:https://inflammatoryboweldisease.net/living/canasa-ulcerative-colitis
Or, if you prefer the enema form of mesalamine, then you could check with your doctor about prescribing you Rowasa. Personally, I'm not a fan of enemas. They don't travel well. The suppository form of Canasa is discreet and easy to use. When I'm in a flare, I take a suppository right before going to bed. During the night, it works its magic on my colon.
I started with Pentasa, but like you, I struggled to swallow it. Plus, if I remember correctly, I had to take the medicine four times a day. That, too, became cumbersome to remember. Did I take dose #3? Or did I forget? So, I prefer the suppository form that only needs to be taken once at night. I hope this information helps. If you read my article, you'll see what I like and dislike about Canasa. Let me know how it goes for you. Sincerely--Traci, UC-IBD Team Member
