Counter (6) for dispensing drugs in form of tablets in personal blisters provided with a plurality of container cells (4) for removably accommodating personal blisters each uniquely associable to one patient. The counter (1) has a scanner for reading the barcode borne on the packages of the drugs to identify the type of drug in question. A computer is provided with a data base containing information regarding the drugs and respective recorded prescriptions for single patients in such a manner to display - for each drug identified by the scanner - the overall number of tablets prescribed for the patient. An operator, positioned at a preset operating station, separately inserts the required tablets of the drug identified by the scanner, into an opening of an introduction element, in such a manner that an intermediate storage element moveable longitudinally along the counter may then transfer them into the personal blisters of the patients for whom the drug in question was prescribed.
