Cooper was also charged with taking money from the till but tribunal chairman David Carden
said it was a matter to be resolved between Cooper and his employer, rather than the tribunal to consider.
However, the fact the pharmacist left the premises at various times for 10 minutes or longer, and asked colleagues to "cover" for him to his employers, was contrary to the Pharmacy Council's code of ethics, Carden said.
The incident involving Cooper dispensing the wrong medication, also amounted to malpractice and negligence.
At the time of the hearing counsel for the PCC, Anita Miller, said the pharmacist's conduct "fell seriously short of acceptable", breached the code of conduct for pharmacists, and amounted to professional misconduct.
His actions justified a penalty to protect the public and maintain professional standards, she said.
