Labelling method for identifying drugs to be administered to a patient in a hospital or surgical setting, comprising the steps of: arranging a labelling system (S) comprising at least one data input unit (I 1 ; I 2 ; V), one data processing unit (U) and one printing device (P); identifying a patient (p i ) through the data input unit (I 1 ; I 2 ; I 3 ); associating a drug list (t i ) with said patient, said drug list (t i ) comprising a set of drugs (d i ) to be administered to the patient; generating, through the data processing unit (U), a label content comprising at least one printing field (f d ) for each drug (d i ) of the drug list (t i ), each of said printing fields (f d ) comprising at least one identifier of the respective drug (d i ); printing , through the printing device (P) of said labelling system (S), the generated label content on one or more adhesive labels (1 h ; 1 d ) located on a common support strip , so that the identifiers (w; g) of all the drugs (d i ) of the drug list (t i ) are indicated on said support strip ; each printing field (f h , f d ) being printed on a different adhesive label (1 h , 1 d ), said adhesive labels (1 h , 1 d ) being individually detachable from the common support strip , characterized in that : said support strip is unwound from an endless feeding strip, said method further comprising a step of automatically size-cutting said endless feeding strip which ensures that the strips related to different patients are separated from each other; and the drug printing fields (f d ) comprise at least one colour-painted background (co) identifying the type of drug (f d ). arranging a labelling system (S) comprising at least one data input unit (I 1 ; I 2 ; V), one data processing unit (U) and one printing device (P); identifying a patient (p i ) through the data input unit (I 1 ; I 2 ; I 3 ); associating a drug list (t i ) with said patient, said drug list (t i ) comprising a set of drugs (d i ) to be administered to the patient; generating, through the data processing unit (U), a label content comprising at least one printing field (f d ) for each drug (d i ) of the drug list (t i ), each of said printing fields (f d ) comprising at least one identifier of the respective drug (d i ); printing , through the printing device (P) of said labelling system (S), the generated label content on one or more adhesive labels (1 h ; 1 d ) located on a common support strip , so that the identifiers (w; g) of all the drugs (d i ) of the drug list (t i ) are indicated on said support strip ; each printing field (f h , f d ) being printed on a different adhesive label (1 h , 1 d ), said adhesive labels (1 h , 1 d ) being individually detachable from the common support strip , characterized in that : said support strip is unwound from an endless feeding strip, said method further comprising a step of automatically size-cutting said endless feeding strip which ensures that the strips related to different patients are separated from each other; and the drug printing fields (f d ) comprise at least one colour-painted background (co) identifying the type of drug (f d ). said support strip is unwound from an endless feeding strip, said method further comprising a step of automatically size-cutting said endless feeding strip which ensures that the strips related to different patients are separated from each other; and the drug printing fields (f d ) comprise at least one colour-painted background (co) identifying the type of drug (f d ). <EOS>
