Fixed drug reactions, also known as fixed drug eruptions, are common and so named because they recur at the same site with each exposure to a particular medication.[1] Medications inducing fixed drug eruptions are usually those taken intermittently.[1]

Signs and symptoms[edit]

A painful purple patch of skin that occurs in the same location with repeated exposures to the culprit drug is the classic presentation of a fixed drug reaction. The lips, genitals, and hands are often involved.

Cause[edit]

Medications that are commonly implicated as a cause of fixed drug eruptions include the following:

  1. Fluconazole
  2. Ciprofloxacin
  3. Doxycycline
  4. Clarithromycin
  5. NSAIDs (e.g., ibuprofen)
  6. Trimethoprim
  7. Cotrimoxazole
  8. Phenytoin
  9. Cetirizine
  10. Pseudoephedrine[2]
