Diseases of the skin. Drug therapy of urticaria

Most patients with urticaria can be assessed by taking a relatively simple history with few or no investigations and controlled by a suitable antihistamine given at appropriate times until spontaneous resolution occurs without a complete diagnosis ever being made. Those that do not respond in this way require sometimes quite elaborate investigations, the institution of which would be an imposition in a mild case. Even after full investigation and ringing the changes of all available drugs, too many cases persist to the frustration of all concerned.
