My son developed hives and I wonder if it was because he ate some green bananas. Can hives be caused by a banana allergy?

Generally not: Hives due to food allergy will typically start between 10 and 60 minutes after eating a food, and last for several hours - typically gone by the next day. They will not come back after that, unless the same food is eaten again. Recurrent hives regardless of any recurring ingestion or exposure should be investigated by an allergist. ...Read more

What do I need to know about banana allergy?

Avoidance: As with any food allergy, the only treatment is avoidance. However, if the allergy is mild (e.g., little more than itching in the mouth when eating it), it may be a cross-reaction from a ragweed allergy. If that's the case, allergy injections will very likely make the itching go away. See an allergist for skin testing, so you can find out what is really going on and what you can do about it. ...Read more

I"ve heard nsaids can "bring out" hives, simply because they r prone to do that. Is that the same as having an allergy to them?

I"ve heard nsaids can "bring out" hives, simply because they r prone to do that. Is that the same as having an allergy to them?

Maybe....: That is a tough question. Yes, some people are allergic to nsaids (aspirin, ibuprofen, naproxen, etc) and can get hives. There are some people who are just prone to hives, and sometimes taking an NSAID can trigger them (but not every time). An NSAID allergy can be dangerous. This is something you should discuss with your doctor, and maybe an allergy specialist. ...Read more

Antihistamines: Both Claritin (loratadine) and Clarinex are good antihistamines that are approved for the treatment of hives. There is no reason they cannot be used together although usually it is not necessary. If a food allergic reaction is more than just hives, such as cough, wheezing, throat tightness, vomiting, cramping, light headedness, etc, this is an emergency and requires Epinephrine and a visit to the er. ...Read more
