PIL stands for Patient Information Leaflet - also known as a Package Leaflet (PL). It is the leaflet that is included in the pack with a medicine.

A PIL is written by the pharmaceutical company and is a patient-friendly version of the Summary of Product Characteristics.

All PILs are checked and approved by the UK or European medicines licensing agencies.


If you are unsure about anything or have any questions about the PIL, always speak to a healthcare professional such as a doctor, pharmacist or nurse.


PILs have to contain specific headings, but sometimes the order may be different. These are the usual headings and the information that is included in each section:
