Oh sorry. A lot of research has been conducted about microscopic colitis - both lymphocytic and collagenous. A key learning revealed that many cases were associated with specific medications and over time the research refined these to be NSAIDs (like Ibuprofen ), SSRIs (specific antidepressants such as Sertraline), PPIs (such as Nexium), and less common drugs such as Statins.

I stopped all those when I was diagnosed. I have since reintroduced SSRI because alternative antidepressants just weren’t effective . And luckily it didn’t cause a relapse. I switched to Pepcid for GERD and know I cannot reintroduce ibuprofen without relapse.

Hope that’s helpful.
