How to read Consumer Medicine Information (CMI)
What is a consumer medicine information leaflet?
Consumer medicine information (CMI) gives you information about your medicines. The CMI gives you facts you need to know before, during and after taking your medicine.
A CMI leaflet gives you information on how to use your medicine safely. For example, it tells you about:
- who should take the medicine
- who should not take it
- how to take the medicine
- any known side effects
- other medicines it may interact with
Your pharmacist will give you a CMI when you start a new medicine. You can also ask them for the CMI.
Pharmaceutical companies write the CMIs. They must follow government guidelines on what to include. The information must be correct, unbiased, and easy to understand.
All prescription medicines and some non-prescription medicines have a CMI leaflet.
What other information is in a CMI?
The CMI will also include:
- the brand name of the medicine
- the active ingredients
- other ingredients
- information on the safe storage of medicine
- instructions on what to do if you miss a dose
- instructions on what to do if you have left over medicine
- information on possible interactions with other medicines
- contact details for the pharmaceutical company

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 before taking any new medicine.
Keep all your CMIs in the one place so you can easily find them. You may need to check some details while using the medicine. For example, you may want to check what to do if you miss a dose.
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. You have a right to ask questions.

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 listed in your medicine’s CMI.
Before you start any new medicine, ask your doctor or pharmacist if there are any interactions you should know about.
Tell them about any other medicines (including any over-the-counter and complementary medicines) you are taking.
