I've been off of Effexor XR about two weeks now. I am still experiencing the brain zaps, dizziness, and general irritability. When will these symptoms finally stop? Also, I now have body cramps in my back and stomach--is this related?

I was taking a pretty low dose of effexor a few years ago...I felt hazy in the head for just a couple months as my body streightened itself out but I have not needed antidepressents now for almost 6 years! (And I have to give credit to God because I prayed for joy and he answered) So hang in there.

You didn't slowly cut down? I came off Effexor about a year ago. I cut down 75mg every month. It took 5 months for me to stop altogether. I was still feeling really ill after a year. I was told by a specialist that my doctor had me cut down on them too fast. I still get dizzy and have brain zaps. I have been told that my memory loss is most probably permanent. I did not have any back or stomach cramps.

In clinical studies, the most common side effects with EFFEXOR XR (reported in at least 10% of patients and at least twice as often as with placebo) were constipation, dizziness, dry mouth, insomnia, loss of appetite, nausea, nervousness, sexual side effects, sleepiness, sweating, and weakness.

Antidepressant medications are used to treat a variety of conditions, including depression and other mental/mood disorders. These medications can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take antidepressants for any condition may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. Therefore, it is very important to talk with the doctor about the risks and benefits of antidepressant medication (especially for people younger than 25), even if treatment is not for a mental/mood condition.

Tell the doctor immediately if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed.
