Children's allergy medicine

We all know that when it comes to medication for children, doctors pay extra attention when treating children. Because the probability of children getting sick is relatively small, it is unknown whether many drugs will cause allergic reactions in children. Moreover, for some young children, the dosage of drugs is also particularly particular. So if children are allergic to medicines, what anti-allergic drugs are there? Let me introduce to you

Allergic reaction is an allergic disease, which is an abnormal reaction that occurs when the human body comes into contact with certain specific allergens. It occurs rapidly, usually appearing after 1 to 10 minutes, but can also appear after a few days. It can be caused by a variety of substances, including foreign serum, certain animal proteins (eggs, lamb, chicken, fish, shrimp, crab, etc.), bacteria, viruses, parasites, animal fur, plant pollen in the air, dust mites, paints, dyes, chemicals, plastics, chemical fibers and drugs, etc. All of the above substances are called allergens.

Allergies mainly affect the skin, digestive system and respiratory system. If the skin is affected, rash, urticaria, neurotic edema, and eczema may occur; if the gastrointestinal digestive system is affected, nausea, vomiting, diarrhea, constipation, gastrointestinal spasm, and growth retardation may occur; if the respiratory system is affected, common symptoms include sneezing, runny nose, coughing, and wheezing, allergic rhinitis, bronchial asthma, and laryngeal edema. In addition, systemic symptoms may include decreased blood pressure, increased heart rate, pale skin, edema, and weak pulse. In severe cases, shock or even death may occur.

1. Antihistamines

Antihistamines are divided into first-generation antihistamines and second-generation antihistamines. Histamine is an allergen released during an allergic reaction. This type of drug can block histamine type I receptors and reduce allergic reactions. It is mainly used for urticaria, allergic dermatitis, and allergic cough.

Representative drugs:

First-generation antihistamines: chlorpheniramine, phenergan, diphenhydramine, etc. Doctors and parents should not give phenergan or other allergy medicines containing promethazine hydrochloride to children under 2 years old.

Second-generation antihistamines: astemizole (Cetirizine), terfenadine (Mindy), loratadine (Claritin), zoltec (Cetirizine), etc. It is much more expensive than the first generation of anti-allergic drugs, but has little effect on the central nervous system and has no or only mild drowsiness effect.
