Parenteral antihistamines and glucocorticoids are medications used to relieve or prevents allergic symptoms and anaphylaxis, which are administered intravenously (IV) or intramuscular (IM). An acute allergic condition is due to the immune system hypersensitivity to environmental substances. Anaphylaxis is a hypersensitivity response to an offending agent. It has a rapid onset of action, and the signs and symptoms are mild and sometimes life-threatening.


The main objective of this paper is to outline the use and the effectiveness of parenteral antihistamines and glucocorticoids in the management of acute allergic conditions and anaphylaxis.


Several methods were applied to obtain information on the use and effectiveness of parenteral antihistamines and glucocorticoids in managing allergic conditions and anaphylaxis. Online details used for systematic reviews, randomized controlled trials (RCTs), quasi-randomized controlled trials (RCTs), controlled clinical trials (CCTs). Controlled before-after designs (CBA), interrupted time series (ITS) studies, and case series. Systematic reviews were performed using standard methods, and appropriate assessment tools were used. Anaphylaxis management plans and allergen-specific immunotherapy are the primary long-term management.


During the study, the use and valid measures of the glucocorticoids and the antihistamines shall be analyzed. This shall be with the amount of evidence manifested through randomization tests regarding previous studies carried out in the same field. Findings shall be investigated and recommendations concerning warrant award of using a particular treatment method for treatment regarding the phases of the progression in acute allergies and anaphylaxis. Emergence adrenaline administration shall also be affirmed on its practical use as a lifesaver.


Recommendations shall be made concerning the availability and sufficiency of evidence shown. Previous works done shall also be useful in the judgment of treatment methods.


An acute allergic response is an ordinary condition that is evident in the emergency department. The tendency of allergic disease is due to both genetic and environmental substances. These non-toxic environmental substances comprise of various airborne elements, poison from insect and drugs. Allergens are the antigens that are involved in producing the phenomenal immune response in which it is fought off an anticipated threat that otherwise would cause no harm to the body. The medication of allergic reaction is effected through immune mechanisms, which mainly belong to type I and IV hypersensitivity of Gell and Coombs reaction. The involvement of type II and III is hardly noticed. Symptoms associated with allergies do range from the localized rash to fatal condition-anaphylaxis. To date, no particular definition of anaphylaxis is established. However, it is mainly considered to describe a swift growth, threatening of lives, acute allergic response. Anaphylaxis results from loss of cytoplasmic granules and basophils with successive liberation/discharge of inflammatory mediators; histamine, tryptase, prostaglandins, cytokines - interleukins among other TNF/ILs into the bloodstream. Activation of mast cells and basophils triggers the anaphylactic reaction virtually. However, it implicates mainly on allergens; Foods, Drugs, Stings, Latex, and Allergen immunotherapy injections. The presence of these inflammatory mediators leads to contraction of smooth muscles, excellent vascular permeability and vasodilation, angioedema, low blood pressure, and bronchoconstriction.

To determine the particular allergen causing the skin, allergic reaction patch testing is done. The substances causing the allergy that are in common within the adhesive patches are employed behind the person. Examining the potential local allergies takes approximately 48 hours from patch application. Avoiding known allergens is the first treatment mode for allergies. While managing long term conditions of anaphylaxis, triggers should be strictly avoided. This is confirmed by undertaking allergology research. Besides, there is the use of medications like steroids and antihistamines in allergies treatment. Researchers recommend that acute allergies be prevented from advancing to anaphylaxis by administering injectable adrenaline (epinephrine). Recognizing anaphylaxis remains a challenge regarding the quality of the criteria of diagnosis used. In turn, the requirements lead to a slow administration of suitable medication prompting high chances of death. Validated clinical measures can be applied to aid the diagnosis of anaphylaxis. It is important to sensitize people regarding the significance of allergic reactions-hay fever since the substantial buildup of allergens is inhibited. Currently, research states that anaphylaxis fatality medical condition cases have risen in a range of specialties, thus enough evidence that the condition perception is not uncommon as previously considered. A different approach has been applied by researchers to investigate the prevalence of anaphylaxis; Emergency department (ED) information, or the count of EAI's prescribed cases-according to the report the visiting rate of anaphylaxis cases approximated to 0.5%. The mortality cases data report are sparse, and publications indicate noticeable variations approximating to 2.7 million cases yearly. American hospital statistics analysis state that one in three thousand inpatients encounter an anaphylactic reaction at death risk approximating to 1%. Thus, 500-1000 death cases are reported in the US due to anaphylaxis. The Brazilian report state that the mortality rate due to anaphylaxis approximates 1.1 million yearly. Findings made that drugs mainly catalyze responses. Besides, these death cases commonly included deaths that occurred in health facilities, the ED, and patients who were dead on arrival.

Administration of adrenaline should not delay the administration of glucocorticoids and the H1-antihistamines management of the anaphylactic patient, thus avoid an end acute episode. Nevertheless, it is unpopularly more of treatment. Simple allergies are primarily medicated through the symptomatic method with the help of steroids and antihistamines.

Primarily, low blood pressure is the main feature in anaphylaxis, while on the other hand, low blood pressure is not a remarkable feature. Anaphylaxis condition is the onset and rapidly progresses, and the chances of mortality are very high within a short time. Typical allergic response causative agents are not extreme with low chances of death. In the treatment of anaphylaxis, adrenaline is compulsorily recommended and must be inclusive of regime medication. For normal allergic reactions, adrenaline is rarely used for the procedure. Irrespective of their distinguishing traits, both anaphylaxis, and allergic reactions tend to manifest similar characteristics.

Anaphylaxis is the advanced state of life-threatening form of allergies distinguished by circulatory problems. Anaphylaxis presentation involves various a combination of symptoms with mild signs, which progresses to fatal anaphylactic shock an anticipated. Common signs and symptoms include itching skin, generalized hives, swelling of impaired tissues, wheezing, and hypotension. The anaphylactic condition can be manifested in the form of response to any type of foreign substance to the body. Generally, allergens include: insect foods-which are commonly displayed in children, bites, and drugs-are mainly in adults. Food allergies can prompt severe consequences. Adrenaline is the primary medication for anaphylactic patients since it boosts the blood pressure, thus life-saving drugs in anaphylaxis. Typically, anaphylaxis existence is due to an IgE-dependent immunological mechanism that is mainly triggered by the allergens mentioned above. However, there are other pathophysiological occurrences like IgE-independent immunologic processes and direct mast cell activities that are involved.

In diagnosing the rapid developing anaphylactic condition, many clinical systems are employed concerning the manifestation of signs and symptoms observed within 2 hours of allergen exposure. The prompt diagnosis of the disease assures maximal management.

Most frequent signs and symptoms displayed by anaphylactic conditions mentioned earlier affect the skin, itching, and flushing; thus, approximately 90% of patients are affected. Besides, the respiratory symptoms are other features that mostly change 70% of patients. Gastrointestinal symptoms (GI) - abdominal pain and v...
