Could Cymbalta Help Reduce Your Fibromyalgia Pain?
Cymbalta has been approved by the FDA for the management of fibromyalgia and has been demonstrated to help reduce pain and improve function. Cymbalta is available only by prescription.
Although the exact way that Cymbalta works in people is unknown, it is believed to be related to an increase in the activity of serotonin and norepinephrine, which are two naturally occurring substances in the brain and spinal cord.
When Cymbalta was studied in patients with fibromyalgia, some people felt significant pain reduction, compared with patients taking placebo. Your individual results may vary.
Cymbalta Is Simple to Take
Cymbalta comes in a capsule and can be taken once a day to help lessen pain associated with fibromyalgia. Cymbalta can be taken with or without food. You should not break, open, or chew the capsule. It should be swallowed whole. Make sure you take only the dose your doctor prescribes.
Cymbalta is not for everyone. As with all medications, certain side effects may be experienced.
In clinical studies, the most commonly reported side effect of Cymbalta was mild to moderate nausea. Read more about the most common side effects and potential risks associated with treatment.

What should I talk about with my healthcare provider?
