Frequently asked questions
Can I stop medicines I think I do not need?
Do not stop prescribed medicines on your own — some can be harmful to stop suddenly. Instead, ask your doctor or pharmacist for a review, and they can safely reduce or stop what is no longer needed.
How often should medicines be reviewed?
Older adults on several medicines should have a review at least once a year, or sooner after any hospital stay or medicine change, to keep treatment safe and necessary.
