Was on 75mg of effexor (venlafaxine) for last 7 weeks and have been upped to 150mg for the last week or so. feel worse than what i was when i was on zoloft.

Let treating dr know: It is common for some medications to work well and others may not work as well. You need to let your treating Dr. know and medications may need to be adjusted or switched until the right one or combination of them works best for you. Good luck.

Call or see doctor: and talk to them and explain your symptoms and ask them to change your medication.

Intolerance: Discuss this with your physician as you have been taking effexor (venlafaxine) long enough to get accustomed to it by now. He/she may agree to have you resume zoloft or another medication.
