I've been taking generic Effexor XR 75 mg for about 3 or 4 weeks now for anxiety/depression and I've been noticing that I'm having a sensation of feeling short of breath after taking my medicines in the afternoon. Obviously, it isn't fun to feel like there are issues with your ability to breathe, but I'd like to know if anyone here had issues with this and if it eventually resolved itself over time. Any useful or helpful information is much appreciated.
