Kissing allergies found in people suffering from food allergies can be treated by adopting simple methods, say researchers.
Even brushing your teeth or waiting hours after eating may not prevent some partners of people with food and medicine allergies from triggering an allergic reaction through a kiss, according to allergists.
AdvertisementSymptoms include swelling of the lips or throat, rash, hives, itching and wheezing.
"If you have food allergies, having an allergic reaction immediately after kissing someone who has eaten the food or taken oral medication that you are allergic to isn't highly unusual," said allergist Sami Bahna, MD, ACAAI past president.
"But some patients react after their partner has brushed his or her teeth or several hours after eating. It turns out that their partners' saliva is excreting the allergen hours after the food or medicine has been absorbed by their body."
Allergists have recommended that the non-allergic partner brush his or her teeth, rinse his or her mouth and avoid the offending food for 16 to 24 hours before smooching with a person who is highly allergic to that food.
But even these steps may not help in some cases.
Dr. Bahna referred to a case of a 30-year-old male with a peanut allergy who has had recurrent anaphylaxis, a life-threatening allergic reaction.
This patient developed lip swelling and itching in his mouth when his girlfriend kissed him. She had eaten peanuts two hours earlier, brushed her teeth, rinsed her mouth and chewed gum prior to seeing him.
When things turn more intimate, allergies can be disruptive as well.
Allergists have seen cases of people experiencing allergies to chemicals in spermicides, lubricants, latex or even a partner's semen.
Some people develop hives or wheezing from the natural chemicals released by their body by the emotional excitement or physical exertion during sexual interaction.
For people allergic to their partner's semen, Dr. Bahna suggests the use of condoms or desensitization (immunotherapy, allergy shots) by an allergist. Preventative antihistamines may be helpful in mild cases.
"There may be more who are suffering from this than we know because people may be embarrassed to bring it up," said Dr. Bahna.
"But allergists can help determine what's causing the allergy and find the right treatment. No one has to suffer," Dr. Bahna added.
