Woman has anaphylactic reaction after oral sex

Penicillin taken by her partner might have been the cause, says BMJ Case Reports

A woman started vomiting, had dyspnoea and full-body urticaria shortly after a sexual encounter, in what doctors believe was an anaphylactic reaction triggered by amoxycillin in her partner’s semen.

The 31-year-old woman is thought to have had the reaction after engaging in oral sex with her partner, 32, who had taken amoxicillin four hours before to treat his otitis media.
