I took benadryl (diphenhydramine) at 745 for an allergic reaction to antibiotics. when will it kick in?

Dose and frequency : dependent! So you may have taken it too long ago or not enough. If you're still itching with rash you should see your PCP to make sure that it's not anything more serious that you may need something stronger. So call your doctor and be seen in person for the best care. Always good to get a professional opinion.
