Duloxetine
Summary
Duloxetine is used to treat depression, anxiety, and certain types of pain, such as nerve pain from diabetes or fibromyalgia, which is a condition causing widespread pain and tenderness.
Duloxetine works by increasing serotonin and norepinephrine levels in the brain, which are chemicals that help improve mood and reduce pain.
Duloxetine is usually taken as a capsule, once or twice daily, with or without food. The starting dose is often 30 mg, which may be increased to 60 mg daily.
Common side effects of Duloxetine include nausea, dry mouth, and dizziness, which are usually mild and may improve as your body adjusts to the medication.
Duloxetine can increase the risk of suicidal thoughts, especially in young adults, and may cause liver damage. It should not be used by individuals with uncontrolled narrow-angle glaucoma, which is a condition where fluid pressure in the eye increases.
