Vonoprazan-associated Microscopic Colitis and Continued Use After Onset: A Study Using a Japanese Pharmacovigilance Database

Using the JADER database, this study identified a safety signal for microscopic colitis associated with vonoprazan which is not listed in its package insert. Patients might continue vonoprazan after the onset of microscopic colitis. Although the database relies on spontaneous reporting, these findings warrant further investigation.
