Hello,
Fatigue and dry mouth and dyspepsia are frequent
side effects of Vesicare but it is unlikely to cause any
sore throat. Your sore throat can be due to some viral infection. Drink plenty of fluids throughout the day and use over-the-counter throat lozenges. Salt water gargle is also a good way to relieve a sore throat. In addition, you can take anti inflammatory drugs like ibuprofen and paracetamol (acetaminophen) after consulting your general physician.
