Nine guides to the medicines people use every day: how to take them, how to combine them safely and when to ask a professional. Each guide links to in-depth articles that answer one specific question, with doses, tables and named products.

How to use these guides: start with the guide that matches your question, then open the article that fits it most closely. Every article names its sources, usually official product information and national health services (NHS, Healthdirect, FDA, TGA), and gives the date it was last updated. The information is general: your doctor or pharmacist can take your own health and other medicines into account. How we write and check the guides.
