Changing prescribing in the light of tolerability concerns: how is this best achieved?

Despite our knowledge regarding the efficacy, tolerability and optimal use of drugs, suboptimal prescribing still occurs. In view of all the factors that influence prescribing, this is not surprising. The focus of drug tolerability has changed from 'choosing the best alternative' when a drug is prescribed, to a balanced decision incorporating various different treatments from separate healthcare providers. This article reviews strategies that may influence prescribing behaviour and discusses practical considerations for achieving optimal prescribing in view of tolerability concerns. The patient has a major influence on prescribing and, with the current diversification of healthcare, the patient now controls prescribing behaviour more than ever before. Communication between healthcare providers consequently assumes a vital role. If messages are to be coherent and transferable, it is increasingly important that healthcare workers communicate effectively with one another regarding patients, prescribing patterns, and drug tolerability issues.
