... the pharmacy..here is my story; 2 yrs ago I had a hysterectomy 3 months later my GYN prescribed Effexor 37.5 for my mood swings..I've been taking this med with no symptoms, 2.5 wks ago I called my primary doctors office and asked for a refill of the med.. I picked up the med and started to take it as I have for the past 2 yrs, a wk into taking this batch I started to feel sick and once I check the dosage on the bottle I realized that the office had called in the wrong dosage, I was taking 75 mg instead of my regular 37.5..Im having bad symptoms like nauses, vomiting, lack of sleep feeling awful..I called my doctors office and told them what was going on..my concern now is how do I go back to 37.5 without making my symptoms worse..help!
