Hi,I have allergies and ate something that might have been contaminated with one of my allergens.(shellfish). I took 2-4 bottle caps of benadryll about 8 pm ( half an hour after consuming the food ) since i had taken 20mg of certizine that morning (10 am). When i had bath i found that i had a flat red rash on my leg. So i drank some green tea and took a 25mg diphenhydramine capsule about 11:30pm. The rash is slower disappearing but i still little itchy spots here and there. Should i take another 25 mg diphenhydramine?
