Prescribing of a medicinal product is a decision taken within the relationship between a patient and his\/her treating health care provider (HCP). The purpose of this article is to discuss the medicolegal aspects of off-label drug use, to provide recommendations for obtaining informed patient consent for off-label treatment and to propose the place and role of scientific societies and specialist boards in shaping good practices in this area. The final aim is to present recommendations concerning off-label usage and propose special clauses in informed patients consent.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>The literature was reviewed regarding off-label applications in laryngology.

Off-label prescribing is not prohibited by EU law. Informed consent to treatment with an off-label drug exists in all EU countries. The risk that a court will accept liability of a HCP in case of off-label prescribing is higher than in case of on-label prescribing. If a HCP is held liable for the outcome of a medical treatment, the approval by the competent authorities and professional guideline is a strong defense.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>A patient\u2019s precise, explicit consent for the procedures including off-label drugs administration is mandatory.
