Be Aware

This drug can increase the risk of bleeding and bruising, especially if taken with aspirin or other blood thinners or NSAIDs.

Combining this or other SNRI drugs with alcohol or other depressants (including antihistamines, narcotics and some dental anesthetics) can make side effects more severe. Also, many of the medicines used to treat fibromyalgia work by boosting the amount of serotonin in your body. Taking two or more of these drugs together could lead to a potentially life-threatening condition called serotonin syndrome. Symptoms usually begin within hours of combining the drugs and include confusion, agitation, irregular heartbeat, unstable blood pressure, tremors, muscle rigidity, nausea and vomiting. If you have these symptoms, stop taking your medication and seek immediate medical help.
