Dr gave salt and water injection; MISCONDUCT.
A Medical Council inquiry heard Dr Lee Seng Khoo failed to give an elderly woman a prescribed antibiotic, instead giving a saline solution.
It happened while working at Sligo General Hospital last August.
The Malaysian doctor was found guilty of professional misconduct by a Fitness To Practise Committee Of The Irish Medical Council.
The three-person committee recommended the Medical Council issue a EUR2,500 fine and suspend his licence to practise for three months.
