So far, you are the only respondent - maybe because others read about the risks and decided against starting it.

Mirabegron is also called myrbetriq, harder for me to pronounce and remember.

I have avoided similar meds in the past due to their link with cognitive issues, but was told by my urogynecologist that there were no reports of Mirabegron causing cognitive issues.

I recently Googled this, however: "There have been post-marketing reports of confusion, hallucinations, insomnia and anxiety in patients taking mirabegron. The majority of these patients had pre-existing medical conditions or concomitant medications that may cause confusion, hallucinations, insomnia and anxiety." This causes me some anxiety.

I also have issues about my continuing need for acetaminophen (possible liver issues), increasing bp & many reports of hair loss with Mirabegron.
