The Medical Council has found two public doctors guilty of professional misconduct after they failed to issue a patient with the medicine she required.
The doctors at United Christian Hospital did not give Tang Kwai-sze preventative antiviral drugs for hepatitis B and in 2017 she suffered liver failure.
Tang subsequently had two liver transplants and died later that year.
The council on Thursday revoked the licence of Dr Lam Chi-kwan for five months, suspended for three years, and revoked the licence of Dr Chan Siu-kim for three months, suspended for one and a half years.
