Skin: adverse drug reactions

Synonym(s): Cutaneous adverse drug reactions; ADR; ADE

Contributor(s): Tim Nuttall, Maarja Uri

Introduction

  • Adverse drug reactions (ADR) or adverse drug effects (ADE) are harmful and unintentional reactions that occur at normal therapeutic doses.
  • Term 'drug hypersensitivity' or 'drug allergy' is saved for immune-mediated idiosyncratic ADRs (Type B ADRs, table 1).
  • ADRs are common in human medicine and occur in 16.8% of hospitalized patients; the prevalence of fatal ADRs in human medicine is 3%.
  • Uniform data about prevalence in veterinary healthcare is not available, but they are likely to be under-reported.
  • The UK Veterinary Medicines Directorate (VMD) received 3755 reports in 2011. Of these, 47% were classified as reaction to a veterinary medication used at manufacturers' recommended dose (31% of the reports lacked sufficient data for further analysis though).
  • The most common drugs associated with veterinary ADRs according to VMD report in 2011 are were:
    • 1. Vaccines (53%).
    • 2. Ectoparaciticides (7.6%).
    • 3. Antimicrobials (7.5%) (mostly beta-lactams and sulphonamides).
    • 4. NSAIDs (6%).
    • 5. Anti-neoplastic agents (0.6%).
  • Human ADRs are most commonly associated with antimicrobials (22%) and NSAIDs (17%).
  • These figures may simply reflect frequency of use rather than specific pathology.
  • It is generally accepted that a veterinary ADR is a significant contributor to patient's morbidity and mortality.
