Do antihistamines like benadryl (diphenhydramine) help prevent oral allergy syndrome?

Probably not: Oral allergy syndrome is usually caused by pollens and sometimes nuts. Claritin, zyrtec and Allegra (fexofenadine) can help with pollen allergies. But like any other allergy, it is best to stay away from the problem. Have an allergist test you and see what treatment would be best.

while avoiding the food helps, there is some evidence that allergy shots for the pollens can help reduce the symptoms from the fruits/vegs that cause OAS.
