Living with Fibromyalgia, Drugs Approved to Manage Pain

"One of the challenges is that fibromyalgia hasn't always been recognized as a specific illness," says Jeffrey Siegel, M.D., clinical team leader in FDA's Division of Anesthesia, Analgesia, and Rheumatology Products. "In 1990, the American College of Rheumatology developed criteria for diagnosing it, and this marked a major step forward in helping more people understand how to recognize the symptoms and how to treat them." back to top.

Treatment with Lyrica, Cymbalta, and Savella may reduce the level of pain experienced by some people with fibromyalgia. Lyrica, Cymbalta and Savella reduce pain and improve function in some people with fibromyalgia. While those with fibromyalgia have been shown to experience pain differently from other people, the mechanism by which these drugs produce their effects is unknown. There is data suggesting that these drugs affect the release of neurotransmitters in the brain. Neurotransmitters are chemicals that transmit signals from one neuron to another.

But men and children also can have it. It mostly affects women, and tends to develop in early to middle adulthood. Fibromyalgia affects 2 to 4 percent of the population, according to the American College of Rheumatology (ACR).

This chemical helps transmit and amplify pain signals to and from the brain. According to ACR, people with fibromyalgia can have abnormal levels of Substance P in their spinal fluid.

Some people with fibromyalgia also experience depression. Like some other antidepressants, Cymbalta may increase the risk of suicidal thinking and behavior in people who take the drug for depression. Cymbalta's side effects include nausea, dry mouth, sleepiness, constipation, decreased appetite, and increased sweating. Cymbalta, marketed by Eli Lilly and Co., was previously approved to treat depression, anxiety, and diabetic peripheral neuropathy.

Each day seemed like an eternity and so I had to focus on just getting through one day at a time.". The pain and exhaustion were so bad that there were days that the only activity I was able to do was walk from my bed to the mailbox and back to bed. "I had a yoga instructor coming to my house three times a week to help me get out of bed.

Some people with the condition may also experience irritable bowel syndrome, pelvic pain, restless leg syndrome, and depression. People with fibromyalgia can experience pain anywhere, but common sites of pain include the neck, shoulders, back, hips, arms, and legs. In addition to pain and fatigue, other symptoms include difficulty sleeping, morning stiffness, headaches, painful menstrual periods, tingling or numbness of hands or feet, and difficulty thinking and remembering. back to top.

For example, fibromyalgia can be distinguished from arthritis because arthritis causes inflammation of tissues and joints and fibromyalgia does not. There is no diagnostic test for it. Another condition with similar symptoms, hypothyroidism, can be confirmed with a blood test. Doctors make a diagnosis by conducting physical examinations, evaluating symptoms, and ruling out other conditions. Family physicians, general internists, and rheumatologists are the doctors who typically treat fibromyalgia.

People with fibromyalgia may find relief of symptoms with pain relievers, sleep medicines, antidepressants, muscle relaxants, and anti-seizure medications. But medication is just one part of the treatment approach.

Savella is not used to treat depression in the United States, but acts like medicines that are used to treat depression (antidepressants) and other mental disorders. Side effects include nausea, constipation, dizziness, insomnia, excessive sweating, vomiting, palpitations or increased heart rate, dry mouth and high blood pressure. Savella, marketed by Forest Pharmaceuticals, Inc., is the first drug introduced primarily for treating fibromyalgia. Antidepressants may increase suicidal thoughts or actions in some people.

"I finally had to stop working in 1995 and spent most of the next two years in bed," she says.

"My husband always believed me, and when you have that kind of support it makes a difference. It's really about facing chronic pain for the rest of your life. So dealing with the emotional impact and not just the physical side is very important.". Emotional support also is essential, Matallana says.

Those gatherings grew into the National Fibromyalgia Association (NFA), an organization that now provides support, research information, medical education, and messages of hope to millions. "We called ourselves 'the pillow posse' because we would meet and have our pillows to support our aching bodies," Matallana says.

Researchers are looking at the role of Substance P and other neurotransmitters, and studying why people with fibromyalgia have increased sensitivity to pain and whether there is a gene or genes that make a person more likely to have it. back to top.

They both had seen numerous doctors before being diagnosed with fibromyalgia, a chronic condition characterized by fatigue and widespread pain in muscles and joints. They both had trouble finding medical information and support for coping with the illness. After meeting on the Internet in 1997, Lynne Matallana and Karen Lee Richards discovered they had a lot in common. Seven months after meeting, they started gathering with five other people with fibromyalgia who also wanted to bring awareness to the issue.

People with fibromyalgia are typically treated with pain medicines, antidepressants, muscle relaxants, and sleep medicines. In June 2007, Lyrica (pregabalin) became the first FDA-approved drug for specifically treating fibromyalgia; a year later, in June 2008, Cymbalta (duloxetine hydrochloride) became the second; and in January 2009, Savella (milnacipran HCI) became the third.

People with rheumatoid arthritis, lupus, and spinal arthritis may be more likely to have the illness. Scientists believe that the condition may be due to injury, emotional distress, or viruses that change the way the brain perceives pain, but the exact cause is unclear.

Walking, jogging, biking, gently stretching muscles, and other exercises also can be helpful. What helped Matallana was a combination of medicines for pain and sleep, treatment for some of the overlapping conditions like migraines and irritable bowel syndrome, and a combination of water therapy, massage and yoga.

Studies of both drugs showed that a substantial number of people with fibromyalgia received good pain relief, but there were others who didn't benefit.

"Some of them even made references that it was all in my head. I was eventually misdiagnosed as having lupus.". "Many doctors suggested that it was just stress," she says.
