Gabapentin is an anti-convulsant drug, similar to pregabalin, which is mainly prescribed for the treatment of seizures. According to a 2007 study, fibromyalgia patients who consumed Gabapentin in regular dosages ranging from 1200 mg to 2400 mg for around 12 weeks were found to experience lesser pain than those who were prescribed placebo. In fact, it has also been reported that these fibromyalgia patients experienced lesser fatigue and better sleep.
Although this new drug has still not been approved by FDA for fibromyalgia patients, scientists and experts in the field believe that gabapentin serve as a good option for treating chronic pain conditions like fibromyalgia.
However, not all have reported to benefit from Gabapentin. In a 2014 review comparing all relevant studies and trials done on Gabapentin, researchers concluded that 35% of fibromyalgia patients received at least 50% reduction in pain and saw improvement in sleep, fatigue, mood, daily function and quality of life. It is better to consult your doctor before you start consuming Gabapentin for treating fibromyalgia.
