How and where you store your medication safely at home depends on several things. Essentially, in accordance with the Care Quality Commission guidelines, medicines should be stored in a way that means they are safe and effective when administered.
Each medication will come with its own storage requirements specified by the manufacturer. Some, for instance, must be stored at certain temperatures and others may be for emergency usage only and therefore stored separately to other medications to save confusion.
Each person needing healthcare at home support will have their own set of medical concerns as well as prescribed and non-prescribed medications. If the visiting personal carer is responsible for overseeing or administering medication, they will make sure that the medication is safely returned to its safe storage before they leave.
If you have any questions about how to store your medication safely at home, you should always contact your GP or pharmacist in the first instance. If your healthcare at home carer has the relevant permissions to liaise with your GP on your behalf, they may be able to do this for you.
