overactive bladde
"I've been taking 8mg Toviaz for several years now. Dry mouth, constipation, dizziness and initially nausea have been side effects. I've had weight gain but being on other meds, I'm not sure if Toviaz has been a contributing factor for the weight gain.  Toviaz has worked very well for my overactive bladder until recently, when I began taking Primidone for tremors. I will discuss this with my doctors to see if Primidone may be causing the Toviaz to be less effective. Also, even with my health insurance, Toviaz is very expensive. Talk with your doctor; weigh the pros/cons for yourself to decide if it's worth taking. I have to say it's been worth it for me. Instead of getting up 4-6 times during night to urinate, I may get up 1 time while on it"
