PY - 2019 T2 - The Color Atlas and Synopsis of Family Medicine, 3e AB - A 26-year-old man was prescribed trimethoprim-sulfamethoxazole for sinusitis and broke out in hives 1 week later. The hives were all over his trunk and arms (Figures 156-1 and 156-2). He denied throat tightening, trouble breathing, and lip or periorbital swelling. 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 urticaria disappeared over the next 2 days.
