Pregnancy can affect the excretion of drugs due to the change in the body quality of pregnant women, and improper use of drugs may lead to fetal malformation or even miscarriage in serious cases. Most of the drugs used to treat rhinitis are anti-allergic and hormonal, which are harmful to the fetus and therefore are not recommended for pregnant women. When a pregnant woman has a rhinitis attack, she can use saline to wash her nose to effectively relieve and treat the rhinitis with less harm to her body. Through the bactericidal effect of saline and the impact of the water, the pathogenic bacteria and dirt that have gathered in the nasal cavity can be discharged to restore the normal physiological environment of the nasal cavity, and it is recommended to use special nasal rinsing tools. In addition, pregnant women with rhinitis should drink more hot water, eat lightly, take rest and avoid excessive fatigue. Strengthen physical exercise, improve the immunity of the body, and pay attention to the development of good hygiene habits. If you are allergic, you should avoid contact with allergens and try to wear a mask when you go out. If a pregnant woman suffers from severe rhinitis and has systemic discomfort, it is recommended that she seek medical attention and take reasonable medication under the guidance of a doctor, not without permission.
