If you do an on-line search you'll find many articles about drugs for fibro. Harvard Health says: "The FDA has approved three drugs specifically for treating fibromyalgia, including pregabalin (Lyrica), duloxetine (Cymbalta), and milnacipran (Savella). However, other medications, such as amitriptyline (Elavil), cyclobenzaprine (Flexeril) or gabapentin (Neurontin) are usually considered first-line treatments. Each of these drugs is prescribed for other conditions, such as depression or nerve pain."
I haven't tried any of these meds as I've read the side effects are often not worth any relief and your body builds up a tolerance to them so doses have to be increased. Your body also develops a dependence on them so there will be withdrawal issues if you want to stop the meds.
