Some people: get a paradoxical reaction to benadryl (diphenhydramine). Whereas it makes most people tired, it can make some jittery. The effects should fade in 4-6 hours. Make sure to tell any health care providers about this reaction in the future. It is not an allergy, but they will want to know to anticipate it before giving you the medicine if you need it. Hope this helps!
