Drugs not being just a product like any other, prescribers, providers and patients must have access to the information relating the characteristics of such medicinal products. This information must be complete, objective and scientifically rigorous. It must be adapted to the use of the drug and be fully understandable. It should help in prescribing, expedite dispensing, and help the patient adhere to treatment. Thus, according to the recipient, the information will be different. It is the role of the pharmacist and the physician to use it for patient education. The information given must be objective. Medication guidelines published by HAS (Haute Autorité de Santé/National Health Agency) and Inserts given with the drugs should be considered the most reliable. Information can also be found in major scientific publication journals, in independent papers produced by groups of doctors and pharmacists, or in treatment guidelines. One must be very reserved about such information found on certain "Internet" sites.
