However, drugs often contain many different substances, including dyes, which could cause allergic reactions. This can cause an allergic reaction on the first administration of a drug.

It is a type of hypersensitivity, specifically immune complex hypersensitivity . The term serum sickness–like reaction (SSLR) is occasionally used to refer to similar illnesses that arise from the introduction of certain non-protein substances, such as penicillin .
The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug.

A patch test (contact delayed hypersensitivity allergy test) [17] is a commonly used examination to determine the exact cause of an allergic contact dermatitis. According to the American Academy of Allergy, Asthma, and Immunology, "patch testing is the gold standard for contact allergen identification".
Like other drug-induced SCARs disorders, AGEP is a type IV hypersensitivity reaction in which a drug or its metabolite stimulates cytotoxic T cells (i.e. CD8 + T cells) or T helper cells (i.e. CD4 + T cells) to initiate autoimmune reactions that attack self tissues. SCARs are type IV, subtype IVb (DRESS syndrome), type IV, subtype IVc (SJS, SJS ...
