Answer

Antihistamines

Antihistamines prevent the histamine response in sensory nerve endings and blood vessels. They are more effective in preventing a histamine response than in reversing it.

Cimetidine (Tagamet)

Cimetidine is an H2 antagonist that, when combined with an H1 type, may be useful in treating itching and flushing in anaphylaxis, pruritus, urticaria, and contact dermatitis that do not respond to H1-receptor antagonists alone. Use this in addition to H1 antihistamines. Other H2 antagonists are also available.

Diphenhydramine (Benadryl, Benylin, Bydramine)

Diphenhydramine is used for the symptomatic relief of allergic symptoms caused by histamine released in response to allergens.
