Diphenhydramine can alleviate itching from poison ivy by blocking histamine receptors, but it’s less effective than topical corticosteroids which reduce inflammation directly.
Diphenhydramine offers temporary relief for poison ivy itching by acting as an antihistamine. However, corticosteroids are generally more effective as they also address inflammation.
