Olanzapine for the treatment of fibromyalgia symptoms.
Fibromyalgia is a chronic condition that is diagnosed primarily by the presence of generalized pain along with tenderness on palpation of certain body regions. Unfortunately, the pharmacological treatment of fibromyalgia remains problematic. Two patients are described who highlight the use of the atypical neuroleptic olanzapine for the control of symptoms related to fibromyalgia. Prior to the use of olanzapine, both patients had received a multitude of treatments, none of which greatly improved their ability to function in daily activities. With olanzapine, both patients reported a significant decrease in pain and marked improvement in daily functioning. In one case, the pain returned during a period of time when olanzapine was discontinued, an effect that was reversed when olanzapine was reintroduced. The paucity of serious side effects (i.e., extrapyramidal signs) with the atypical neuroleptic olanzapine strongly favors further exploration and use of this drug for the treatment of fibromyalgia symptoms.
