Q: Effexor Withdrawal effects

How long do the Effexor withdrawal effects last? I recently was prescribed effexor and took it for exactly 13 days before I decided to call it quits (I stopped taking it a few days ago). I have recently felt a little nauseous and have been having dizzy spells. How long will this last?

Hello and welcome to the site

One should never stop this medication on there own accord



Were announced to the stop of the treatment: aggressiveness, agitation, anorexia, anxiety, asthenia, confusion, convulsions, incoordination, diarrhoea, dizzy spells, dryness of the mouth, dysphorie, fasciculation, tiredness, grippaux symptoms, cephalgias, hypomanie, disorders of balance and coordination, insomnia, nauseas, nightmares, nervousness, paraesthesias, feelings of electric shock, disorders sensory (including feelings resembling electric shocks), sleep disorders, somnolence, perspiration, acouphene, tremors, giddinesses and vomiting. If necessary, these symptoms were usually spontaneously resolvent, but they persisted during several weeks in certain cases. During studies of pre-marketing, the symptoms were, for the majority, from light intensity and disappeared without treatment. L' appearance of symptoms with l' stop of the antidepressants treatments being a well-known phenomenon, it is recommended, when it is possible, to reduce posology gradually and to supervise the patient. L' interval between l' appearance of symptoms and the reduction of the amount or l' stop of the treatment varies between the patients; the symptoms can occur the same day or several weeks later. (See also Undesirable effects, Symptoms related to l' stop of the treatment and Posology and d' mode; administration, Stop of the treatment with the venlafaxine.)
