GMC Guidance • keeping up to date and prescribing safely • need and objectivity - prescribing for yourself and those close to you • consent to prescribe - explaining benefits, risks and side effects of medicines; improving adherence • sharing information with and prescribing at the recommendation of colleagues • repeat prescribing, prescribing with repeats and reviewing medicines • prescribing online, by telephone and video-link • prescribing off-label and unlicensed medicines, including for reasons of cost-effectiveness • conflicts of interest - prescribing incentives and financial interests in pharmacies, pharmaceutical companies and dispensing practices • sports medicine - prescribing performance enhancing drugs

Is the prescription…… • • Ethical ? Evidence Based ? Safe? In line with practice, local and national guidance ? Cost effective ? Given with Informed consent ? Practical ? Do I understand the implications?

Risks associated with medication errors are particularly high in the following groups of patients: • the old, particularly when frail • those with multiple serious morbidities • those taking several potentially hazardous medications • those with acute medical problems • those who are ambivalent about medication taking or have difficulty understanding or remembering to take medication

Drugs commonly associated with preventable harm in general practice Drugs with narrow therapeutic index eg, • digoxin • methotrexate • warfarin

Drugs commonly associated with preventable harm in general practice Other commonly used drugs • anti-thrombotics such as aspirin • cardiovascular drugs including diuretics, betablockers and ACE inhibitors • CNS drugs including anti-epileptics, opioid analgesics, and psychotropics • drugs used for the treatment of diabetes • NSAIDs • systemic corticosteroids

Top 10 tips for safe prescribing 1. Keep yourself up-to-date in your knowledge of therapeutics, especially for the conditions you see commonly 2. Before prescribing, make sure you have all the information you need about the patient, including co-morbidities and allergies 3. Before prescribing, make sure you have all the information you need about the drug(s) you are considering prescribing, including side effects and interactions 4. Sometimes the risks of prescribing outweigh the benefits and so before prescribing think: ‘Do I need to prescribe this drug at all? ’ 5. Check computerised alerts in case you have missed an important interaction or drug allergy

Top 10 tips for safe prescribing 6. Always actively check prescriptions for errors before signing them 7. Involve patients in prescribing decisions and give them the information they need in order to take the medicine as prescribed, to recognise important side-effects and to know when to return for monitoring and/or review 8. Have systems in place for ensuring that patients receive essential laboratory test monitoring for the drugs they are taking, and that they are reviewed at appropriate intervals 9. Make sure that high levels of safety are built into your repeat prescribing system 10. Make sure you have safe and effective ways of communicating medicines information between primary and secondary care, and acting on medication changes suggested/initiated by secondary care
