INTERACTIONS
Effexor can interact with various medications and substances, potentially affecting its efficacy or causing adverse effects. Here are some common drug interactions to be aware of:
Monoamine Oxidase Inhibitors (MAOIs)
Do not take Effexor if you are currently using or have recently used MAOIs, as this combination can lead to dangerous serotonin syndrome.
Other Antidepressants
Combining Effexor with other antidepressants, such as SSRIs (selective serotonin reuptake inhibitors) or tricyclic antidepressants, should be done cautiously and under medical supervision to avoid excessive serotonin levels.
Blood Thinners
Effexor can interact with blood-thinning medications like warfarin, potentially increasing the risk of bleeding. Regular monitoring of clotting times is necessary if these medications are used together.
