I have been taking pseudoephedrine for many years for relief of nasal stuffiness. In the past 5-6 months I have been experiencing urinary retention, going to the emergency room once. I read the warnings of possible side effects, one being urninary retention--in men. I am a woman, no prostate gland involved here. In looking back at any of the symptoms and when they occurred, they occurred during the time I was taking pseudoephedrine. I have found no possible side effects listed referring to women having urinary retention. Has any other woman out there had this occur?
