Occupational allergy to pharmaceutical products

Area of Science:

• Occupational Health
• Allergology
• Pharmacology

Background:

• Occupational allergy in healthcare workers presents significant costs due to lost productivity and treatment expenses.
• Traditional allergens like penicillin continue to be problematic, but sensitization patterns are shifting.

Purpose of the Study:

• To provide an updated overview of drugs implicated in causing occupational allergy.
• To highlight emerging drug classes and changing sensitization patterns in occupational allergy.

Main Methods:

• Review of recent literature on occupational drug allergy.
• Analysis of reported cases and sensitization patterns in healthcare and pharmaceutical workers.

Main Results:

• Cephalosporins are increasingly implicated, with up to 17% of healthcare workers showing sensitization in some studies.
• Proton pump inhibitors and benzodiazepines are also reported drug classes.
• Certain drugs, like omeprazole and tetrazepam, are highly sensitizing via topical or inhalation routes, even if rarely causing allergy in patients.
• Occupational allergy is no longer confined to healthcare settings, affecting pharmaceutical employees as well.

Conclusions:

• Diagnosing occupational drug allergy can be lengthy, often taking up to 5 years.
• Workplace avoidance is the primary management strategy.
• Up-to-date awareness of implicated drugs and allergy patterns is essential for timely symptom resolution.
