Introducing Cymbalta Cap 30mg, a medication containing the active substance duloxetine. Cymbalta works by increasing serotonin and noradrenaline levels in the nervous system. It is prescribed for adults to treat depression, generalized anxiety disorder, and diabetic neuropathic pain. Typically, Cymbalta begins to ease symptoms of depression or anxiety within two weeks, though it may take 2 to 4 weeks for full relief. Inform your doctor if you do not notice improvement. Cymbalta's mechanisms in managing depression, pain, and anxiety are linked to its enhancement of serotonergic and noradrenergic activity in the central nervous system.
