Can benadryl capsules be broken

Patient: Can I break a benadryl capsule and just take the powder?? It’s all I have but have trouble with pills.

Symptoms: Sneezing,itchy eyes and throat.

Doctor: Hello,If you don’t have other oral anti histaminics and you cant swallow the pills then you can have the powder but t he efficacy would be reduced as the coating of the capsule prevents from gastric acid digestion and allows absorption in intestine.so it is better to take the capsule and not the powder.wishing you speedy recovery,regards
