[Photodynamic reaction to carprofen].
Summary
Photoreactions to the non-steroidal anti-inflammatory drug Carprofen are becoming more common. A photo patch test confirmed Carprofen as the cause of a patient
Area of Science:
- Dermatology
- Photobiology
- Pharmacology
Background:
- Increasing reports of photoreactions to Carprofen.
- Photoreactions can manifest as adverse skin responses to medications.
- Carprofen is a commonly prescribed non-steroidal anti-inflammatory drug.
Observation:
- A patient presented with suspected Carprofen-induced photosensitivity.
- A photo patch test was conducted 9 months post-Carprofen exposure.
Findings:
- The photo patch test confirmed a positive reaction specifically to Carprofen.
- No reaction was observed to other tested non-steroidal anti-inflammatory drugs.
Implications:
- Highlights the potential for delayed-onset photosensitivity to Carprofen.
- Suggests the need for careful patient history and phototesting in suspected cases.
- Differentiates Carprofen as a specific photosensitizing agent among NSAIDs.
