 In 2017 there was a proposal for 3,200 over the counter (OTC) drugs to be restricted and 18 procedures to be added to the list.This generated some controversy amongst doctors with some arguing that OTC should be blacklisted instead, and others believing the move didn't take into account individual patient needs.The NHS has produced lists of procedures of limited clinical effectiveness for many years, advising that they should not be carried out except in exceptional cases.
