Which antibiotic class commonly requires sun protection due to photosensitivity?

• A. Tetracyclines
• B. Sulfonamides
• C. Macrolides
• D. Fluoroquinolones

Answer: (D)

Photosensitivity is a notable side effect to watch for with some antibiotics, where sunlight can trigger an exaggerated skin reaction. The fluoroquinolones are especially linked to this issue. When someone takes these drugs and spends time in the sun, they can develop sunburn-like redness, itching, or even blistering in sun-exposed areas, sometimes with only modest sun exposure. The reason is that the drug can absorb UV energy in the skin and promote phototoxic reactions, damaging skin cells. Because of this risk, you’ll often be advised to protect the skin: use sunscreen, wear protective clothing and hats, and avoid tanning beds or intense sun when on a fluoroquinolone. While tetracyclines can cause photosensitivity as well, the need for strict sun protection is most consistently emphasized with fluoroquinolones in clinical guidance.
