After feeling so ill with chest pains and shortness of breath , blurred vision and generally unwell I decided to check this medication out on this site. I had been prescribed Naproxen approx 2years ago for arthritis, I am also taking an antidepressant. I had treatment for blood clots in both lungs (albeit 40years ago. ) I was horrified when I realised that I was experiencing many of the side affects associated with Naproxen and it would appear that with my medical history I probably shouldn't have been prescribed this medication. I have now stopped taking this medication,and would appreciate some advice please.
