The contents printed or pasted on drug packaging are collectively called labels, which are divided into built-in and external. The general contents of the inner label and the outer label are the same, but there are also differences. The internal label shall include the generic name, indications or functional indications, specifications, usage and dosage, production date, product batch number, expiration date, production enterprise, etc. The external label shall indicate the general name, ingredients, properties, indications or functional indications, specifications, usage and dosage, adverse reactions, contraindications, precautions, storage, production date, product batch number, expiration date, approval number, manufacturer, etc. Don't worry about the repetition and verbosity of drug packaging labels. Each item is very important and plays an important role in drug packaging design. 1. Generic name of drug: the same drug is used internationally, which is convenient for doctors and consumers to know what drug is being used and prevent the same drug from being used repeatedly. Among them, trademarks, trade names and generic names of drugs are obviously different in the printing of labels, which is easy to identify. 2. Ingredients: it is convenient for doctors and consumers to know the ingredients in drugs, to prevent repeated use of drugs, and to prevent the ingredients in different drugs from causing side effects and adverse reactions when patients take other drugs. 3. Characteristics: It is convenient for manufacturers, business enterprises, medical institutions and consumers to know what the characteristics of normal drugs are, and it is convenient for the above-mentioned institutions or personnel to find out the problems of drugs in time when drugs are contaminated or otherwise. 4.
