How does this medication work? What will it do for me?
Duloxetine belongs to the class of medications called selective serotonin and norepinephrine reuptake inhibitors (SSNRIs). It is used to treat depression and generalized anxiety disorder. It can also be used to treat diabetes-related nerve pain, fibromyalgia, chronic low back pain, and chronic pain from osteoarthritis of the knee.
For depression and anxiety, duloxetine works by affecting the balance of chemicals in the brain and other parts of the body. For certain types of pain, duloxetine works by affecting the balance of chemicals in the brain and spinal cord that are involved in the experience of pain.

How should I use this medication?
The usual recommended dose is 60 mg once daily. Some people may start on a lower dose of 30 mg once daily. Elderly patients with generalized anxiety disorder should be started at a dose of 30 mg once daily. It usually starts to work within 1 to 4 weeks for depression and anxiety and within the first week of treatment for diabetes-related nerve pain, fibromyalgia, chronic back pain, and chronic osteoarthritis knee pain.
Duloxetine should be taken at the same time each day. It can be taken with or without food, but taking it with food may help to reduce nausea that may occur at the start of treatment.
Swallow capsules whole. Do not crush or chew the capsules, and do not sprinkle the contents of the capsule into foods or liquids.
