The 5 Moments for Medication Safety are the key moments where action by the patient or caregiver can greatly reduce the risk of harm associated with the use of their medication/s. Each moment includes 5 critical questions. Some are self-reflective for the patient and some require support from a health professional to be answered and reflected upon correctly. This tool for patient engagement has been developed as part of the third WHO Global Patient Safety Challenge: Medication Without Harm. It is intended to engage patients in their own care in a more active way, to encourage their curiosity about the medications they are taking, and to empower them to communicate openly with their health professionals. This tool is intended for use by patients, their families and caregivers, with the help of health professionals, at all levels of care and across all settings. For patients, families and caregivers Pay attention to these 5 MOMENTS when using medication/s. ASK these QUESTIONS and FIND the ANSWERS with the help of a health care professional whenever you: visit a doctor, nurse, pharmacist or dentist visit a primary health care facility or pharmacy are admitted to and discharged from a health care facility are referred to another health care facility are transferred to another health care facility receive treatment and care at home. For health professionals Promote patient engagement by introducing this tool to your patients, their families and caregivers and supporting them in answering the questions. 1. STARTING A MEDICATION What is the name of this medication and what is it for? What are the risks and possible side-effects? Is there another way of treating my condition? Have I told my health professional about my allergies and other health conditions? How should I store this medication? 2. TAKING MY MEDICATION When should I take this medication and how much should I take each time? How should I take the medication? Is there anything related to food and drink that I should know while taking this medication? What should I do if I miss a dose of this medication? What should I do if I have side-effects? 3. ADDING A MEDICATION Do I really need any other medication? Have I told my health professional about the medications I am already taking? Can this medication interact with my other medications? What should I do if I suspect an interaction? Will I be able to manage multiple medications correctly? 4. REVIEWING MY MEDICATION Do I keep a list of all my medications? How long should I take each medication? Am I taking any medications I no longer need? Does a health professional check my medications regularly? How often should my medications be reviewed? 5. STOPPING MY MEDICATION When should I stop each medication? Should any of my medications not be stopped suddenly? What should I do if I run out of medication? If I have to stop my medication due to an unwanted effect, where should I report this? What should I do with leftover or expired medications?
