What causes tiredness, anxiety and chest pain after taking venlafaxine?
human
I wanted to know if there was a difference in taking (3) venlafaxine er 75 mg capsule, extended versus a 150 mg tablet ? What I had done without consultation is take a 150 tablet of venlafaximine and a 75 mg er, but started feeling extremely tired and anxious on top of chest pain which was checked out to be normal at the er.

HIThanks for using healthcare magicIt is the side effect of venlafaxine at higher dose. You have taken three tablets of venlafaxine  and at higher dose, it causes hypertension, anxiety symptoms and chest pain. Nothing to worry about that. Just take two tablets and try to stay at same dose for next few days. After that, try to escalate the dose. Rest, you can discuss with your doctor. In case, you need further help, you can ask.Thanks
