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 comprising at least one data input unit (I 1; I 2; V), one data processing unit and one printing device; 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, 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 of said labelling system, 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 comprising at least one data input unit (I 1; I 2; V), one data processing unit and one printing device; 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, 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 of said labelling system, 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).
