A cosmetic surgeon, who claimed promethazine did not have a sedative effect, has failed to convince a tribunal to overturn his suspension for giving the drug and fentanyl to procedural patients despite being banned from administering conscious sedation.

The Sydney-based GP was suspended last July following an immediate action hearing, with the Medical Council of NSW finding his continued administration of conscious sedation in contravention of his conditions to be “premeditated and deliberate”.

The council said the suspension also reflected his failure to “meaningfully engage” with the emergency hearing, after he left the online meeting to pick up his children and never returned.

His suspension, which was imposed initially in 2015 and updated in late 2017, stipulated he was “not to administer any conscious sedation or monitor any sedated patients”.
