Duloxetine is an antidepressant medication that belongs to the class of serotonin-norepinephrine reuptake inhibitors (SNRIs). It is commonly prescribed to treat major depressive disorder, generalized anxiety disorder, and certain chronic pain conditions such as fibromyalgia, diabetic neuropathy, and chronic low back pain. Duloxetine works by increasing the levels of serotonin and norepinephrine, two neurotransmitters in the brain that help improve mood, alleviate anxiety, and manage pain. By balancing these chemicals, duloxetine helps regulate emotions and reduce physical discomfort. The typical dosage of Duloxetine is 20 mg, though it may be adjusted depending on the condition being treated. Common side effects include nausea, dry mouth, dizziness, and fatigue. It is important to follow a doctor’s guidance when taking this medication, as sudden discontinuation may cause withdrawal symptoms.
