• Monoamine oxidase inhibitors (MAOIs) such as phenelzine or tranylcypromine along with the antibiotic linezolid — observe recommended washout intervals (commonly at least 14 days).
• Concurrent use with other SNRIs like duloxetine — increases the chance of unwanted health consequences.
• Nefazodone for depression treatment and some older monoamine agents that affect brain monoamines.

• Periodic blood pressure and heart rate checks are recommended because venlafaxine can raise both in some people.
