Patient information leaflets (PILs) contain specific information about medical conditions, doses, side effects that are packaged with medicines to inform users. PILs are the European equivalent of package inserts. Manufacturers are required to include a PIL but sometimes avoid the cost. The document then outlines the key sections that should be included in a PIL, such as identification of the medicine, therapeutic indications, dosage instructions, description of side effects, and additional information. It emphasizes using plain language, short sentences, and grouping side effects by seriousness to improve patient understanding of risks.
