Lupex-GR 20 Tablet contains Duloxetine 20mg, a selective serotonin and norepinephrine reuptake inhibitor (SNRI) used primarily in the management of major depressive disorder, generalized anxiety disorder, diabetic peripheral neuropathic pain, fibromyalgia, and chronic musculoskeletal pain. Duloxetine acts by increasing the levels of serotonin and norepinephrine in the central nervous system, which helps regulate mood and pain perception. This medication is indicated for patients requiring symptomatic relief from depression and anxiety, as well as those suffering from neuropathic pain conditions. Lupex-GR 20 Tablet should be administered as prescribed by a healthcare professional, typically once or twice daily, with or without food. It is essential to adhere to the prescribed dosage and not discontinue therapy abruptly to avoid withdrawal symptoms. Common side effects may include nausea, dry mouth, dizziness, fatigue, and constipation, while more serious adverse effects such as hepatotoxicity or serotonin syndrome are rare but require immediate medical attention. Caution is advised in patients with a history of liver disease, glaucoma, or bipolar disorder. Lupex-GR 20 Tablet should not be used concomitantly with monoamine oxidase inhibitors (MAOIs) or other serotonergic drugs. Regular monitoring by a healthcare provider is recommended to assess therapeutic response and tolerability.
