What's consumer medicine information?

Consumer medicine information (CMI) is designed to inform you about prescription and pharmacist-only medicines. CMI leaflets are written by pharmaceutical companies, who have to follow government guidelines about what to include and ensure their information is accurate, unbiased and easy to understand.

What must the CMI contain? 

Providing standard key information in a non-biased, plain English style, the CMI will include:

  • who the medicine is approved for
  • who should not take it
  • how to take it
  • important potential side effects and interactions to be aware of.

A CMI leaflet must be produced by the manufacturer for all prescription and some non-prescription medicines. Sometimes it is included in the pack. You can search for and download the CMI leaflet for any medicine in our Medicine Finder, or you can ask your pharmacist.

Read the CMI to ensure you get the best and safest use of the medicine, or to learn more about a medicine you’re already taking. For example, you can find out about its side effects and interactions. Take it with you to your doctor or pharmacist to discuss any questions about the medicine.

Where can you get your CMI?

  • Find it using our Medicine Finder
  • Ask your pharmacist or doctor to print it for you.
  • Sometimes you can find it inside the packet or box.
  • Phone Medicines Line on 1300 633 424. You can ring 9 am to 5 pm, Monday to Friday, Eastern Standard Time.
  • Contact the medical information department of the pharmaceutical company that made your medicine. You can find their number in the phone book.

To ensure you have the right CMI, check that the brand name on the CMI (usually the largest text) exactly matches the brand of your medicine.

Always read the CMI before starting a new medicine. You may also want to refer to it while using the medicine — for example, to check if another medicine interacts with it, or what to do if you miss a dose.

All CMIs follow the same format, so it’s easy to find the information you need.

Keep it handy so you can refer to it later. Don’t use it to try and diagnose, treat, cure or prevent illness yourself.

Finding trustworthy medicines information

Information about the benefits and side effects of medicines can come from many sources, including the internet, the media, even family and friends. It can often be hard to judge which information is useful and what is exaggerated hype — or even nonsense. For example, news stories might describe 'new research', or 'scientific evidence' in a way that sounds conclusive, but may not be reliable, so it pays to be careful.
