Which photosensitivity agent is NOT listed as an offender in the material?

• A. Sulfonamides
• B. Tetracyclines
• C. Amiodarone
• D. Acetaminophen

Answer: (D)

Photosensitivity reactions occur when certain drugs absorb UV light and transfer energy to skin tissues, producing damage that looks like an exaggerated sunburn or dermatitis. Classic offenders include sulfonamides, which readily cause phototoxic eruptions; tetracyclines, known for intense sun sensitivity and bright erythema on sun-exposed areas; and amiodarone, which can cause a distinctive photodermatitis with a slate-grayish tint due to its iodine-containing structure and long tissue half-life. Acetaminophen, on the other hand, does not have significant photosensitizing properties and is not typically listed among the agents known to cause phototoxic or photoallergic reactions.
