How to read CMIs

3-minute read

You need to understand the medicines you are taking. The Consumer Medicine Information (CMI) leaflet has information about your medicine. This will help you get the best out of your medicine and know what to do if you miss a dose. It will also help you know what to do if you have any side effects.

What is consumer medicine information?

A CMI leaflet gives you information on how to use your medicine safely and properly. For example, it tells you:

  • how to take the medicine
  • why it may have been prescribed for you
  • who should not take it
  • potential side effects
  • other medicines it may interact with

CMIs are available for:

Where to find your CMI

You can get your medicine’s CMI by:

  • checking the medicine packaging (it is usually inside)
  • asking your pharmacist or doctor to print it for you
  • phoning the Medicines Line on 1300 633 424 (9am to 5pm, Monday to Friday, Eastern Standard Time)
  • searching in healthdirect's medicines section
  • searching NPS MedicineWise Medicines finder
  • contacting the maker of your medicine – the contact details are on the company’s Australian website

Using your CMI

Always make sure you have the right CMI. Check that the brand name on the CMI matches the brand name of your medicine.

Read the CMI of your new medicine before taking any.

Keep all your CMIs in the one place so you can easily find them. You may also need to re-check some details while using the medicine.

Speak to your doctor or pharmacist if there’s anything in the CMI that worries you.

Understanding interactions

Sometimes one medicine can affect how another medicine works. One medicine can change the side effects of another. This is called an ‘interaction’.

Interactions can also happen between medicines and certain foods or drink, including alcohol.

Known interactions are usually listed in your medicine’s CMI.

Before you start any new medicine, you should ask your doctor or pharmacist whether there are any likely interactions you need to know about.

Tell them about any other medicines (including any over-the-counter and complementary medicines) you are currently taking.

Is this medicine right for me?

If you have read the CMI and you aren’t sure whether the medicine is right for you, talk to your doctor or pharmacist immediately. You have a right to ask questions.

Where to get help

The best place to get help is from your doctor, hospital or pharmacist. If you have a life-threatening emergency, call triple zero (000).
