I don't think weight gain is listed as a side effect, but I started taking Myrbetriq on a Friday then started an exercise regimen along with a healthy diet (and drinking about 100 oz of water a day) on Saturday and in a week, I'd gained about 5 pouinds. I don't know if the medication reacted to my other medications to cause the weight gain, but it happened.

I just started gaining weight after only 2 weeks of using Myrbetriq. I gained 1.6 lbs in 1 day, but all together it is 4 1/2 lbs.
