Avoid taking MAO inhibitors (e.g., furazolidone, isocarboxazid, linezolid, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) with venlafaxine for 2 weeks before treatment, during treatment, and at least 7 days after your last dose of venlafaxine. Consult your doctor or pharmacist for more information.
