A member asked:

I am on suboxone, 4mg sublingual films. will starting 150mg effexor (venlafaxine) interfere with my suboxone use? or will they counteract each other at all?

A doctor has provided 1 answer

Serious interaction: There is a serious drug interaction between suboxone and effexor (venlafaxine) causing something called long QT syndrome. This is a heart conduction problem. It is not a good idea to combine those two medications.
