Who should not take Effexor?
You should not take Effexor if you are taking another drug used to treat depression called a Monoamine Oxidase Inhibitor (MAOI), or if you have stopped taking an MAOI in the last 14 days. Taking Effexor and an MAOI within a close period of time can result in serious (and sometimes fatal) reactions including high body temperature, coma, and seizures (convulsions).
