A serotonin-norepinephrine reuptake inhibitor, venlafaxine raises brain levels of both neurotransmitters to help regulate mood and anxiety. It treats major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. Marketed as Effexor, it has the formula C17H27NO2. Because it can raise blood pressure, particularly at higher doses, treatment is accompanied by blood-pressure monitoring, and abrupt discontinuation can produce withdrawal symptoms.

This serotonin-norepinephrine reuptake inhibitor (SNRI) antidepressant is used to treat major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. It works by increasing the levels of serotonin and norepinephrine in the brain, which helps regulate mood and anxiety. Blood pressure should be monitored as it can cause small increases, particularly at higher doses.

                                Venlafaxine + Tramadol
                            
                        

                        
                        
Venlafaxine and tramadol together pose a high risk of serotonin syndrome due to complementary serotonergic mechanisms.
