It doesn’t always work for some of us.
I can be on predisone and 50 mg of Benadryl for days and I still swell, and still get breathing problems 3-4 days after the sting. The shortness of breath reaction is a delayed reaction that Benadryl doesn’t seem to help.
Most doctors say that for insect stings that that kind of dose of Benadryl is the only thing to use. Other anti-histamines just don’t cut it; they’re not strong enough.
I will remember that, Benedryl dosage, if I have the misfortune of a bee or wasp sting in the future.
Of course I will be a zoned out puppy taking 50mg -— but at least I won’t itch or hurt because I won’t be feeling a thing :)
