Which medication is appropriate for mild localized urticaria without airway compromise?

Mild localized urticaria is driven by histamine release in the skin, which causes itch and welts. The best way to manage this is by blocking histamine’s effects with an H1 antihistamine, which reduces both itching and swelling. Diphenhydramine fits this role, providing effective relief in mild cases without airway involvement. Epinephrine is reserved for serious reactions with airway compromise, not for simple, localized hives. Antibiotics aren’t indicated unless there's a bacterial trigger, which isn’t the scenario here. An ice pack can help with comfort but doesn’t treat the underlying histamine-driven process, so it’s not the primary medication choice.
