Used primarily in the treatment of major depressive disorder, generalized anxiety disorder, and panic disorder. It functions as a serotonin-norepinephrine reuptake inhibitor (SNRI), helping to restore the balance of certain natural substances in the brain, such as serotonin and norepinephrine. Patients may begin to feel improvement after several weeks of continuous use. Also prescribed off-label for managing chronic pain, neuropathic pain, and migraine prevention. Commonly formulated in immediate-release and extended-release tablets for oral administration. Should be used as prescribed by a healthcare provider; abrupt discontinuation may lead to withdrawal symptoms such as dizziness, insomnia, or mood swings.
