I take medication for my bladder inoctence (vesicare). what are the possible side effects?

Here are some...: It is a good habit to ask your prescribing doc for this sort of questions since s/he knows more about your individual clinical profile. However, Vesicare as one of antimuscarinic agent may over-express its intended effects for ease urinary urgency but resulting in unbearable dry mouth, constipation, urinary retention, blurred vision, change in mentation, etc.
