Detection of serum specific IgE Detection of serum specific IgE can only detect allergens of rapid allergy, Allergens that cannot be detected for other types of allergies must be analyzed for clinical correlation. Only when the symptoms are relieved or disappeared after avoiding the allergens, and the allergens that are positive in the excitation test may be related to the disease. What drugs can be used for allergies? 1. Soft hormone if only dermatitis symptoms appear, Usually short-term external hormone cream is enough, Soft hormones are preferred. Soft hormones refer to hormones that are absorbed little by the whole body or can be rapidly decomposed into inactive products after being absorbed in the skin. Its advantage is that the absorption amount is very small, High activity is retained only locally, As a result, adverse reaction are greatly reduced, The treatment index is greatly improved. Soft sex hormones are suitable for the elderly and people who need large-scale use. The existing soft sex hormones in China include mometasone furoate and fluticasone propionate. 2.

However, capsaicin can reduce cough sensitivity at the same time, but can try chronic cough. Can allergy become chronic if it is not treated in time? Yes. Improper treatment, especially scalding and scratching, can worsen and chronic the symptoms. Although scalding and scratching can interfere with the transmission of itching sensation by generating pain and temporarily relieve itching, they can also release the analgesic substance serotonin (5-HT) in the brain, activate pruritus-specific neurons to aggravate itching sensation. The more itching, the more scratching, the more scratching, the more itching, forming a vicious circle. Can allergy kill me? Severe allergic reactions can lead to shock, cardiac arrest and even death. This is due to vasodilation and increased capillary permeability during allergy. The heart cannot adapt to this sudden change, leading to cardiovascular failure (coronary artery spasm, myocardial ischemia or infarction, malignant arrhythmia) and even cardiac arrest. The response is to inject epinephrine and other necessary hormones in time. What should be paid attention to at ordinary times?
