It might sound odd, but for those who have a variety of allergies, kissing can be passionately dangerous. Several people have reported to have an allergic attack occurring immediately after a kiss or a peck of the cheek.

Odd or Just Misunderstood?

It is a known fact that allergens are most commonly transmitted via inhalation (allergic rhinitis), ingestion (food allergies), skin contact (dermatitis), or direct blood transmission (intravenous drugs). But transmission through kissing is a bit surprising.

The allergy itself is not due to the lip-locking and lip-smacking; rather, it mainly relies on what the partner has eaten in past few hours—or even days. In 2005, a Canadian teenager died due to hypoxia secondary to an allergic reaction following a kiss from her boyfriend. Later, it was revealed that the teen was allergic to peanuts, and the kiss transpired hours after the boyfriend ate peanut butter. Aside from this, there had been several reports already about asthma and rashes developing on the site of the kiss.

Reactions develop in individuals who are severely allergic to peanuts, tree nuts, medicine, and other substances. These allergens can stay in the saliva of the partner for long periods, and may be transmitted through kissing. In a study published in The New England Journal of Medicine, 5.3% reported allergic responses from kissing. Some reported reactions even after their partner brushed their teeth. This suggests that a higher percentage of the allergic population is at risk.

What you Doctor can do for you?

If you suspect any allergy after exposure to a certain substance, have yourself diagnosed immediately by an allergist. The best thing to do is identify what causes the allergic reaction. The severity is unique per individual. It’s safer to undergo diagnostic tests that assume your condition. If you have severe allergies, the doctor will prescribe life-saving autoinjector containing epinephrine to be carried always with you. Some people may require a Medic Alert bracelet to inform people and health professionals that you require delicate handling because of your condition. Desensitization or immunotherapy is applicable to certain persons. Talk about this with your physician.

What you can do?

“Kissing” allergy is not an allergy itself. It is due to allergens that can be passed on through kissing. You are not required to “totally avoid” kissing. But do make some precautions. It is best to inform your family members or your partner with your condition so that they can adjust with you better—or risk having an asthma attack or worse, anaphylaxis.
