A member asked:
I've felt nauseous and lightheaded for five days after taking 25 mg of benadryl (diphenhydramine) allergy is this normal?
A doctor has provided 1 answer
Too long : 5 days is too long after a single dose of Benadryl (diphenhydramine). Medication is out of your body by now. Wait for another 5 days and if symptoms persist, see your doctor
