A member asked:

Taking effexor (venlafaxine) xr cause me to test positive on a drug test? i have been on effexor (venlafaxine) xr for 3 years.

A doctor has provided 1 answer

No: Drug tests are usually looking for specific drugs of abuse. They don't check for any and all drugs you are taking. The only way Effexor (venlafaxine) will show up is if they specifically look for effexor, (venlafaxine) and there is no good reason for them to do that.
