Abstract
Fibromyalgia is a chronic disease that it needs of a complex and multiple drug therapy. With the aim to study the degree of adherence to therapy in this disease to the pharmacological treatment prescribed and, to know how they influence a series of variables as they are the age, the perceived health, the number of drugs and the difficulty in taking medication, a descriptive study was realized in 50 patients diagnosed of fibromyalgia. The results show us as the most patients are multiple medication and a large percentage present bad adherence to treatment, being in these patients the mean perceived health score significantly higher in chronic problems, compared to those with they have a good adherence. The multivariate logistic regression analysis indicates a high risk of non-adherence in patients who they are multiple medication, they are 60 or older and they have chronic mental problems, although the association only is significant for chronic problems. Therefore, factors as such the number of drugs, the age and the perception that they have about their health, are variables to take into consideration in the degree of adherence to therapy in these patients.
