Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Sumatriptan (Imitrex) and venlafaxine (Effexor) are both prescription medications, but they are used for different conditions and belong to different drug classes. Sumatriptan (Imitrex) is a triptan used to treat migraines in adults, while Venlafaxine (Effexor) is an SNRI used to treat depression, anxiety, social anxiety disorder, and panic disorder. Sumatriptan works by tightening blood vessels in the brain and reducing inflammation, whereas Venlafaxine increases serotonin and norepinephrine activity to help adjust your mood. Sumatriptan is typically taken as needed for migraines, with a maximum of two doses in 24 hours, while Venlafaxine is taken daily, with doses adjusted based on the condition being treated. Sumatriptan can cause side effects like tingling, numbness, and fatigue, and has serious risks like heart problems and serotonin syndrome. Venlafaxine can cause nausea, tiredness, and dry mouth, and has risks like suicidal thoughts and severe withdrawal symptoms if stopped suddenly. Both medications are available in lower-cost generic forms.
