Used primarily in the treatment of major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. It functions as a serotonin-norepinephrine reuptake inhibitor (SNRI), helping to restore the balance of certain natural substances in the brain. It is also prescribed off-label for conditions such as chronic neuropathic pain, migraine prevention, and menopausal hot flashes. The medication is available in immediate-release and extended-release formulations, allowing for flexible dosing regimens. It typically requires several weeks to achieve full therapeutic effect and should be tapered gradually to avoid withdrawal symptoms.
