In addition, the following should be noted and detailed:

  • Interval between introduction of a drug and onset of the eruption

  • Route, dose, duration, and frequency of drug administration

  • Use of parenterally administered drugs (more likely to cause anaphylaxis)

  • Use of topically applied drugs (more likely to induce delayed-type hypersensitivity)

  • Use of multiple courses of therapy and prolonged administration (risk of allergic sensitization)

  • Any improvement after drug withdrawal and any reaction with readministration
