At home

keep a daily checklist of all the medicines you take.
include both prescription and OTC medicines.
note the name of each medicine, the doctor who prescribed it, the amount you take, and the times of day you take it. Keep a copy in your medicine cabinet and one in your wallet or diary.
read and save any written information that comes with the medicine. Check the label on your medicine before taking it to make sure that it is for you or for the person to whom you are giving it.
take medicine in the exact prescribed amount and at the right time. Medicines will be more effective if they are taken exactly as prescribed by the doctor, in the correct dose and monitored regularly for side-effects.
check the expiry dates on the medicines and throw away medicine that has expired.
speak to the doctor or clinic if you have any problems with your medicines or if you are worried that the medicine might not be right for you. It may be necessary to change your medicine to another one.

take medicines prescribed for another person or give yours to someone else.
stop taking medication that has been prescribed for you unless your doctor says it's okay — even if you are feeling better.
mix alcohol and medicine unless your doctor says it's okay. Some medicines may not work well or may make you sick if taken with alcohol.
expect immediate results. Benefits may take several weeks to appear, particularly with anti-depressants.
take the person with dementia to the clinic as well as his or her own doctor and/or psychiatrist. This can result in “polyscripting”, with extensive side effects and even death.
