In a study of Verzenio taken with an AI, it was common for women to experience diarrhea, which was sometimes severe. In some cases, diarrhea led to dehydration or infection. Diarrhea was greatest during the first month and then decreased.
- The median time to first symptoms was 8 days. The median duration for moderate and more significant diarrhea was 11 days and 8 days, respectively. However, some patients experienced this earlier or later in therapy
- The diarrhea was managed by their doctor with an anti-diarrhea medicine (for example, loperamide, which is sometimes sold under the brand name Imodium®) and/or by reducing the dose*
