I’m on Tamsolusin too with no real side effects. Here’s a strange one though. I had pneumonia about 5 years ago and after Iwas given a nose spray (Beconase type thing to use occasionally if I get a cold). I never noticed at the time but I was gettingintermittent ‘water works symptoms – aching lower stomach, a feeling like Ineed a pee all the time – especially at night – up and down all the time. These symptoms lasted for a couple of weeks –even went to the GP and had a PSA test – negative results. Symptoms disappeared for a few months and then would come back.
These symptoms came back last autumn (2014) so I went to my GP. Cut a long story short, another PSA, ultrasound, cystoscopy and a barium Xray to rule out a bowel problem. Specialist diagnosed an enlarged prostate and put me on Tamsolusin last January. However I noticed after a couple of months that my symptoms were getting much worse and didn’t make the connection at first – I had been using the nosespray for a heavy cold for a few weeks. I Googled it and it says on the internet that decongestants can indeed cause prostate symptoms if you are borderline for a prostate problem. Stopped the nose spray 3 months ago – no morewaterworks symptoms.
