Which medication can cause potential photosensitivity, rash, bruising?

• A. Antibiotics
• B. Antidepressants
• C. Antifungals
• D. Antihistamines

Answer: (B)

Some medications used for mood disorders can make skin more sensitive to sunlight and also affect how blood clotting works, leading to photosensitivity, rash, and easy bruising. Antidepressants can cause phototoxic reactions when the skin is exposed to UV light, producing redness or a sunburn-like rash after relatively little sun exposure. They can also increase bruising risk because many of them, especially SSRIs and SNRIs, interfere with platelet function by lowering serotonin in platelets, which is important for clumping and clot formation. This dual risk of light sensitivity and bruising is why this class is the best fit for the described side effects. If sun exposure is necessary, use strong sun protection and watch for unusual skin changes or easy bruising, and discuss any symptoms with a clinician.
