Serious side effects of Effexor XR include clinical worsening of symptoms and suicide risk, especially in younger patients.

Effexor XR may interact with different drugs such as monoamine oxidase inhibitors, and many other types of drugs; the list is extensive. Hyponatremia, hypertension, and exacerbation of bipolar symptoms may also occur.
