Is it true that I must have the authorisation of the Technical Scientific Committee of the EPS in order to undergo a procedure or be given the medicines ordered by my treating doctor?

The treating physician's opinion is sufficient for access to medicines, as he/she is the one who, in addition to possessing qualified medical knowledge, knows the patient's state of health and is able to determine the medicine or procedure that is most appropriate for recovery (Judgment of the European Court of Human Rights). T-053/04, T-190/07).
