Study Notes

Patch Testing and Immunosuppressants

Systemic drugs suppressing T-cell responses also suppress patch test reactions.
Ideal patch testing involves patients not taking immunosuppressant medications (e.g., prednisone, cyclosporine).
If stopping immunosuppressants is not possible, reduce the dose to a minimum to prevent false-negative patch test results.
