How long can swelling from a mild peanut allergy last?

Not long: Swelling from a food allergy reaction typically lasts an hour or two. I'm hoping that you're not asking to determine "whether it's worth it." intentional exposures to a food allergen, even if the reaction is mild, can lead to increasing sensitivity over time. If you're allergic to a food, it's best to completely avoid it.

It depends: Not to be vague in answering your question, but just because a patient has a "mild" allergy does not mean that a severe reaction cannot occur. Several things can affect a reaction. However, most swelling reactions resolve within 24 hours. If not, please see your doctor immediately. Also, if you have experienced tongue or throat swelling, see your doctor immediately as well.
