Tips for staying safe with medication

• Store medicines safely, where children and pets can’t get at them.
• Don’t assume one prescriber knows all the details of how another team is treating you. Tell healthcare professionals about all of the medicines that you are using and how much you take including medication or supplements you buy from a pharmacy or supermarket. This helps them to make the best and safest decisions. 
• Don’t mix prescription medicines with ones you have bought, unless you have checked they are safe together.
• If you have been in hospital, check which medicines and doses have been stopped, started or changed. Make sure your next prescription from your GP matches what you expect. If it doesn’t, ask why.
• Do not stop taking your medications without talking to your doctor, nurse or pharmacist first so it can be done safely.
