You must know about horrible facts about use of medicine I’ve found from WHO in fact sheet no. 338
- The overuse, underuse or misuse of medicines harms people and wastes resources.
- More than 50% of all medicines are prescribed, dispensed or sold inappropriately, and half of all patients fail to take medicines correctly.
- In developing countries, less than 40% of patients in the public sector and 30% in the private sector are treated according to clinical guidelines.
- More than 50% of all countries do not implement basic policies to promote rational use of medicines.
- A combination of health-care provider education and supervision, consumer education, and an adequate medicines supply is effective in improving the use of medicines, while any of these interventions alone has limited impact.
From now on, people must getting more knowledge about medicines they bought before they drink it.
