Depending on the individual’s constitution and the characteristics of the drug, drug dermatitis may occur after medication and is a type of adverse drug reaction.
The clinical diagnosis needs to be based on a comprehensive analysis of the patient’s medication history and drug rash history.
For mild drug rashes, discontinuation of the allergenic drug will most often provide relief.
For severe drug rashes, early and adequate administration of glucocorticoids and gammaglobulin is required.
Prevention is important, for example, by informing the doctor of previous allergies and by conducting skin tests before applying penicillin, streptomycin, etc.
