Physical therapists' knowledge, advice, and administration of nonprescription medications to their clients

Physical therapists often have limited knowledge and little formal training in pharmacology, yet they frequently advise their clients on the use of over-the-counter (OTC) medications and administer these in the course of treatment. This practice may have a bearing on professional liability if side effects and contraindications are not adequately considered. In addition, some nonprescription medications may have an effect on physical therapy care. The purpose of this study was to assess physical therapists' knowledge about OTC medications, and the extent to which they advise clients about OTC medications and administer them. To examine these issues, a self-administered, anonymous questionnaire was mailed to a random sample of 25% of clinical physical therapists registered in New South Wales, Australia (n = 660). It was found that a substantial proportion of practicing physical therapists advised and administered OTC medications despite their limited training and knowledge in the area.
