I've been on Effexor XR 75 mg for about 2 months now with no side effects. My doctor upped my prescription to 150 last week and now side effects. Has anyone ever had these side effects and how long do they last:
-heart/chest pains
-headaches
-waking up many times at night
-unable to reach orgasm (worst one)

Ive had many side effects due to effexor, they lasted the whole time I was on the med, the brain shocks and visual disturbances were the worst.....\

I have been on effexor xr 75mg for 1 month. My doctor up my dose to 150 3 weeks ago and I have had no side effects.

I have had no side effects either! i was on wellbutrin xl and lost weight from it so i was worried that i would gain back the weight once i started effexor and got off wellbutrin but i havent gained any.
