Paraben allergy.

J E Nagel, J T Fuscaldo, P Fireman

    JAMA
    |April 11, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Parabens in hydrocortisone preparations can cause severe allergic reactions like bronchospasm in asthmatic patients. Preservative-free formulations are a safer alternative for individuals with hypersensitivity.

    Area of Science:

    • Allergy and Immunology
    • Pharmacology
    • Respiratory Medicine

    Background:

    • Hydrocortisone is a common corticosteroid medication.
    • Parabens are frequently used as preservatives in pharmaceutical preparations.
    • Asthma patients may have unique sensitivities to drug formulations.

    Observation:

    • An asthmatic patient experienced bronchospasm and pruritus after intravenous administration of a hydrocortisone preparation containing methylparaben and propylparaben.
    • The patient did not exhibit adverse reactions to an identical hydrocortisone preparation that lacked paraben preservatives.

    Findings:

    • Direct and passive transfer (Prausnitz-Küstner) skin tests confirmed immediate hypersensitivity to parabens in the patient.
    • The findings indicate that parabens can elicit immunologically mediated, immediate systemic hypersensitivity reactions.

    Implications:

    • This case highlights the potential for paraben preservatives to cause severe allergic reactions in susceptible individuals.
    • Healthcare providers should consider preservative-free formulations for patients with known or suspected hypersensitivity.
    • Further investigation into paraben hypersensitivity is warranted to ensure patient safety in மருத்துவ contexts.
