PY - 2013 T2 - The Color Atlas of Family Medicine, 2e AB - A 26-year-old man was given trimethoprim-sulfamethoxazole for sinusitis and broke out in hives 1 week later. The hives were all over his trunk and arms (Figures 150-1 and 150-2). He had no airway compromise and had only urticaria without angioedema. His sinus symptoms were mostly resolved, so he was told to stop the antibiotic and take an oral antihistamine. The H1-blocker gave him relief of symptoms and the wheals disappeared over the next 2 days.
