You can, but: Be cautious, both are antihistamines, and you don't want to overdose, start with lower dose benadryl (diphenhydramine), (diphenhydramine) later stick to either benadryl (diphenhydramine) or fexofenadine (allegra). If you don't improve in a day or two, see your doctor, caution if Benadryl (diphenhydramine) makes you drowsy, don't drive, wish you wellness
