A Woman Just Had A Near-Fatal Allergic Reaction To Penicillin In Semen

Doctors urge people to 'be aware' of the risk.

  • A woman in Spain went into anaphylactic shock after performing oral sex and had to go to the hospital.
  • Doctors discovered her partner had taken a form of penicillin, a drug which the woman is allergic to.
  • The case, believed to be the first of its kind ever recorded, was published in the British Medical Journal Case Reports.

Talk about a mood-killer.

A woman from Alicante, Spain recently suffered a life-threatening allergic reaction to penicillin after having sex with her partner, who was taking a form of the medication.

According to The Daily Mail, the unidentified 31-year-old woman had performed oral sex on her partner, and soon after started to vomit. She struggled to breathe and broke out in hives.

When she went to the hospital, doctors realized she was having a life-threatening allergic reaction known as anaphylactic shock. According to The American Academy of Allergy Asthma & Immunology, anaphylaxis can be fatal if not treated.

The Spanish woman told the doctors she was allergic to penicillin but that she hadn’t taken the medication. But, it turns out her 32-year-old partner had recently taken amoxicillin, a form of penicillin, to treat an ear infection. As a result, the doctors believe her anaphylaxis was caused by ‘seminal transfer of amoxicillin.’ The woman had never had this kind of reaction in previous sexual encounters, so her doctors ruled out a semen allergy. But a semen allergy can happen. Really.

According to the International Society for Sexual Medicine, a semen allergy (also known as seminal plasma hypersensitivity), is a rare allergic reaction to proteins found in semen.

Women who have this rare allergy, often experience redness, swelling, pain, itching, and a burning sensation in the vagina (or mouth, if you’re performing oral). The symptoms typically start 10 to 30 minutes after coming into contact with semen. In some women, anaphylaxis can happen.

And it can crop up at any time: Sometimes the allergy is to one partner’s sperm, but not another’s, or it may happen suddenly with a longtime partner. Crazy is an understatement!

Doctors who treated the 31-year-old have now urged anyone with drug allergies to ‘be aware’ of the potential risk from oral sex. Duly noted, doc.
