Journal of the American Medical Association, 1947
Any medicament, no matter how valuable, may do great harm if it is employed indiscriminately. The fame of the new antihistaminic drugs has become so widespread, indeed, that they are often prescribed merely to satisfy the patient's curiosity. A critical inventory of their value is therefore indicated.

The Lancet, 1983
With careful use of antihistamines central effects may be minimised or even largely avoided while adequate peripheral antihistaminic activity is preserved. Tolerance to central effects may develop quickly with some drugs, so that sedation is no longer troublesome after a few days.

Hypersensitivity to antihistamines
Allergy and Asthma Proceedings, 2013Antihistamines are the cornerstone of allergy therapy and are not expected to cause hypersensitivity reactions. We describe two cases, one had urticaria to multiple anti-H1-preparations and the other had anaphylaxis to hydroxyzine. We also provide a review of the English literature on reported reactions regarding causative preparations and ...

Clinical & Experimental Allergy, 1999
Urticaria is one of the most common and, in its chronic course, excruciating dermato‐allergic diseases. Apart from the dermatological diagnosis, the identification and evaluation of causal triggering factors is of utmost importance. Here a ‘three‐step guideline’ (according to Ring and Przybilla) has gained acceptance, ranging from a general basic ...

Acta Physiologica Scandinavica, 1949
Summary.Cats were treated with doses of legation intravenously that suppressed the blood pressure action of moderate histamine doses. The responses of respiration to inhalation of gas mixtures poor in oxygen or rich in carom dioxide were undiminished.

Annals of Otology, Rhinology & Laryngology, 1976
Antihistamines may be used to maximum benefit for the allergic patient if the physician adheres to four guidelines. These guidelines are based upon 1) an appreciation of certain structural and pharmacologic differences among antihistamines, and 2) an understanding of their mechanism of action.

Journal of Clinical Pharmacy and Therapeutics, 2001
Histamine activates pain-transmitting nerve fibres, releases pain-related neuropeptides, and is painful when injected into the skin. Histamine agonists mimic these effects, suggesting that histamine plays a role in mediating the signal transduction of tissue damage or other painful stimulus.

Tuberculosis and Antihistaminics
Diseases of the Chest, 19491) The present knowledge of antihistaminics, particularly the pharmacologic considerations are presented. 2) Tuberculous allergy and tuberculous anaphylaxis are presented as widely different mechanisms and carefully differentiated. 3) Neo-Antergan and phenergan (RP3277) were given for several months in a series of thirty patients with ...

Dermatologic Clinics, 1991
Antihistamines are a diverse group of drugs, each possessing the ability to inhibit various actions of histamine. Because they act principally through competitive inhibition of the histamine receptor, they are helpful as a means of preventing rather than reversing these actions.

Antihistamines and decongestants
Otolaryngology–Head and Neck Surgery, 1992Drug therapy for allergic rhinitis is used either to prevent symptoms from occurring by short‐circuiting the reaction and thus inhibiting the production of chemical mediators or to control symptoms after the target organs have been stimulated by these mediators.
