how long does venlafaxine take to get out of your system once you stop taking it
To determine how long Effexor stays in your system, it is necessary to understand the metabolite of its active ingredient â Venlafaxine. Venlafaxine has an elimination half-life of approximately 5 hours (+/- 2 hours) which is extremely short compared to other popular antidepressants. This means that the Venlafaxine should be fully cleared from your system in about 1.15 days (just over a day). However, when accounting for the +/- 2 hour variability of its half-life, some people may excrete the drug in just 16.5 hours, while others may take nearly 2 days (1.6 days) to completely excrete it.
