Can Diphenhydramine reduce redness and swelling caused by allergic skin reactions, and how effective is it compared to other antihistamines or topical treatments?
Diphenhydramine can reduce redness and swelling from allergic reactions by blocking histamine. It’s effective but may cause drowsiness, unlike non-sedative antihistamines.
Compared to other antihistamines like loratadine, diphenhydramine is faster acting but more sedating. Topical forms target symptoms directly without systemic effects.
