A nurse is before a Nursing and Midwifery Board inquiry for allegedly having the drug crystal methamphetamine in his possession and for ordering another drug from the hospital pharmacy using the names of other staff.
John Benedict Butalid de Lara was employed as a staff nurse at the Royal Hospital Donnybrook in Dublin from December 2003 to November 2014.
The inquiry heard allegations that Mr de Lara ordered the nasal decongestant, Sudafed, from the hospital pharmacy in May 2013, claiming it was for colleagues, when he knew or ought to have known it was not appropriate.
The inquiry also heard that on 31 March 2014, he was found by gardaí to have in his possession crystal methamphetamine and was arrested.
It followed a search warrant on a premises on Marlborough Road in Donnybrook.
The hospital learned of the matter in media reports of court proceedings in July 2014 and Mr de Lara was suspended from work on pay, pending disciplinary proceedings.
Mr de Lara, 45, and from the Philippines, is facing allegations of professional misconduct and disability.
