Summary We describe a 34‐year‐old patient with a probable fixed drug eruption caused by trimethoprim‐sulphameth‐oxazole, having developed the eruption after sexual intercourse with his wife, who was taking the drug. The patient was known to be allergic to trimethoprim‐sulphamethoxazole by history, and the lesion then recurred at the same site when the drug was administered orally to his wife. To the best of our knowledge, this is the first report describing postcoital fixed drug eruption. Physicians should thus be aware of unusual and atypical forms of fixed drug eruption.
