Used as a non-opioid analgesic for the management of moderate to severe pain. It is commonly prescribed postoperatively or for acute pain conditions where opioid use is not preferred. Works primarily by inhibiting the reuptake of serotonin, norepinephrine, and dopamine, contributing to its pain-relieving effects. Also used in some cases for the treatment of shivering during anesthesia or surgery due to its thermoregulatory effects. Not associated with significant respiratory depression, making it a favorable option in certain clinical settings.
