Many Patients Not Given FDA-Advised Starting Dose of Medications, Study Finds
About two-thirds of fibromyalgia patients do not get the starting dose recommended by the FDA in the label it places on an approved medication, a recent study that looked at data collected on thousands of patients over nine years reports. Currently there are three medications approved by the U.S. Food and Drug Administration (FDA) for the treatment of fibromyalgia: Lyrica (pregabalin), Cymbalta (duloxetine) and Savella (milnacipran).  "Only approximately 34% of patients were prescribed FDA-approved drugs for fibromyalgia at the recommended starting dose," the researchers wrote.    Real-world considerations of physicians' prescribing patterns are behind this practice.  "The appropriate dose of fibromyalgia medications can be individualized to optimize the benefits and reduce side effects," the researchers said. The retrospective study, "Analysis of Real-World Dosing Patterns for the 3 FDA-Approved Medications in the Treatment of Fibromyalgia," was published in the American Health & Drug Benefits.  In the study, researchers analyzed real-world prescribing patterns and dosing of these medications based on electronic records stored at the IQVIA's medical database between January 2006 and December 2014. It examined a total of 1,043 patients treated with Lyrica at a starting dose of 176 mg/day, 1,281 treated with Cymbalta at a starting dose of 56 mg/day, and 326 treated with Savella at a starting dose of 95 mg/day. Mean treatment duration with Cymbalta, Lyrica and Savella was 205, 167 and 167 days, respectively. Findings revealed that 35% of patients treated with Lyrica were given a starting dose lower than the recommended dosage in the product label. This also happened in the case of patients treated with Cymbalta and Savella, but to a lesser exte
