How Prescription Duloxetine Helps Relieve Fibromyalgia Pain

In 2008, the FDA approved Cymbalta for the treatment of fibromyalgia in adults.

Duloxetine is an SNRI, which increases the levels of serotonin and norepinephrine. Scientists believe this helps suppress the sensations of pain in the body.  The result is more relief from pain and improved moods.

How is prescription duloxetine taken?

Duloxetine comes in a tablet form and is taken once a day.  Your doctor will recommend the proper dose and regime for you as needed.  Generally, duloxetine is taken in gradually increased doses over time, starting with 30 milligrams the first day for a week and then increasing gradually to a full dose of 60 milligrams per day.   Currently there is no evidence that taking more than 60 milligrams per day is of any added benefit to the patient.
