No. You can take these together but I would not exceed more than 1 or 2 a day of benadryl (diphenhydramine). Benadry is ver sedating.
Drug interactions. According to epocrates there is no interaction between the two drugs.
I took Claritin 24 hours, 12 hours ago but my allergies are out of control again. Can I take half a Benadryl (diphenhydramine) to help with my itchiness?
Yes. Adding Benadryl (diphenhydramine) is fine. If your allergies are out of control you might want to consider adding medicated nasal sprays to your treatment regimen. Consider seeing an Allergist so that you can get better relief. Skin testing to determine sensitivities to indoor and outdoor allergens is useful. If you fail both medications and avoidance measures you might want to consider allergy shots.
I took Claritin 10 hours ago but my allergies are horrible still can I take a Benadryl (diphenhydramine)?
No not good idea. You should not mix antihistamines. It has cumulative effect. Instead why don't you treat the cause of your allergies. Please visit us at www. Ehacstl. Com and you will learn that when you treat the cause you don't need antihistamines, nasal sprays etc.
