Have you ever had an allergic reaction after kissing someone? It’s more common than people realize — and yes, it can be serious.
If your partner has eaten something you’re allergic to, traces of that allergen can remain in their saliva even after brushing or chewing gum. When you kiss, those proteins can transfer to your lips or skin and trigger an allergic reaction. In some cases, the exchange of saliva can even lead to anaphylaxis, which can be life-threatening.
To help take the fear out of Valentine’s Day, here are some food allergy–smart kissing precautions and tips:
❤️ Avoid allergens altogether on dates
❤️ Wait at least 4 hours after eating
❤️ Brush, rinse, repeat — and then brush again
❤️ Share a safe, non-allergenic meal or snack
❤️ Have the food allergy conversation before the kiss
❤️ Skip alcohol (it can increase risk and lower awareness)
❤️ Always carry two epinephrine devices
Because when it comes to food allergies, being safe is always more romantic than being sorry ❤️
