In particular, tell your doctor or pharmacist if you are taking:

Cystitis is a distressing condition caused by an infection and/or inflammation of the bladder. It is normally no more than a painful nuisance and only rarely becomes more serious. Cystitis will occur in 4 out of 5 women at least once in their lifetime, so it is a very common complaint and the attacks usually cause no lasting damage.
