My dr has taken me off lexapro and told me to go ahead and start taking effexor (venlafaxine) with no tapering off. do i still need to expect with drawl symptoms fr?

Stopping Lexapro (escitalopram): You don't say what dose of Lexapro you've been taking or for how long. Both dosage and duration of Lexapro are factors in determining how to discontinue this med. That said, since Effexor (venlafaxine) has the same serotonin increasing property as Lexapro, withdrawal from abruptly stopping is less likely. However, if you experience any withdrawal symptoms, eg, malaise, nausea, insomnia, tell prescribing doc.
