59.4% of drugs allowed by current pharmaceutical nomenclature to be sold without prescriptions may cause side effects or have contraindications. Analgetics, spasmolytics, purgatives and non-steroidal anti-inflammatory drugs account for the bulk of side effects. 87% of over-the-counter drugs contain no information about possible adverse effects. Promoting awareness of the population of side effects of the drugs admitted to prescription-less sale should be considered as an urgent problem of pharmacy.
