Additional information: Clinical course: Any reported event had not required an emergency room visit or Physician Office. Concomitant Products patient reported that she began taking the Myrbetriq about a month and a half ago normally takes it in the morning with food.  The patient reported that she received samples from her doctor before having the prescription filled ad also reported that she was diagnosed with an overactive bladder year ago, probably at least 20 years ago. I would think, but was taking a different medication that was erratic, oxybutynin. Patient-reported that she weighs herself every morning before showering.  Patient-reported that her weight ranges between 110 pounds, 111 pounds, 112 pounds, and sometimes 113 pounds, always with a point something. The reporter thinks that intermittent diarrhea may have begun when she had the first dose of the Covid-19 vaccine and that diarrhea started probably after the first dose of the Covid-19 vaccine on 23Feb2021. The patient is unsure about how long she experienced the intermittent chills and also feeling very tired made her nervous because she is active for her age. The caller reported that the soreness was not a big deal and was nothing to be concerned about after 2nd dose. No Investigation Assessment was reported. The patient was unable to provide details regarding the flu shot that resulted in the sore injection site.  No follow-up attempts are possible. No further information is expected.
