Allergic rhinitis, also known as allergic rhinitis, is what many people are still used to calling allergic rhinitis. The main symptoms of allergic rhinitis are nasal itching, nasal discharge, nasal congestion, sneezing, and loss of smell, etc. Treatment is mainly in four major areas: allergen avoidance; medication; immunotherapy; and surgical treatment. All people are suitable for the principle of “avoiding allergens”, but there is a big difference in “medication and immunotherapy” for different groups of people, and surgical treatment can be considered if medication is not satisfactory. How to treat allergic rhinitis in women during pregnancy, a special group? The treatment of allergic rhinitis should follow a stepwise approach, that is, according to the classification (intermittent/continuous) and degree (mild/moderate/severe) of allergic rhinitis, the condition is treated with antihistamines and glucocorticoids in a progressive order, from mild to severe. Women with allergic rhinitis during pregnancy should also follow the above principles. First of all, they should avoid allergens, use saline nasal rinses, etc. The use of medication and immunotherapy should take into full consideration the impact on the pregnant woman and the fetus and weigh the pros and cons. Pharmacological treatment of allergic rhinitis is mainly antihistamines and intranasal hormones. Drugs commonly used for allergic rhinitis in pregnancy: chlorpheniramine (class B), loratadine (class B), cetirizine (class B), which are all class B drugs, can be used clinically. Second-generation antihistamines (loratadine, cetirizine, etc.) are preferred because they have no drowsy side effects and are safer. The shortest course of oral antihistamines should be half a month. Nasal hormones such as budesonide (budesonide nasal spray) belong to Class B and fluticasone (fluticasone hydrochloride nasal spray) belongs to Class C. Both instructions do not specify that they are contraindicated in pregnant patients, but the instructions for fluticasone propionate nasal spray state that pregnant and lactating women should consult their physician or pharmacist when applying this product. On balance, both are available, and the most clinically used should be budesonide. Avoid oral hormones unless they are life-saving. The adverse effects of oral hormones are large, and relatively speaking, nasal hormones are safer. The course of nasal hormone therapy should be at least one month. The specific course of treatment needs to be chosen at discretion. As for immunotherapy, the guidelines clearly state that it is prohibited in pregnant women. In addition to pharmacological treatment, nasal saline rinses can improve symptoms, clean the nasal cavity, and restore the function of nasal mucosa, etc. Saline or 1%-2% hypertonic saline is recommended [2], which is safe for pregnant patients and can be used. In conclusion, allergic rhinitis during pregnancy is not that medication cannot be used, but it should be used selectively.
