Doctor's reminder: It is recommended to follow the doctor's advice when taking loratadine for a long time. Some netizens have seen it as a "life-saving tool for all seasons". Dr. Xu Haibo from the Third Hospital of Hangzhou reminds that "loratadine is after all an antihistamine and receptor antagonist drug, and the common side effect is drowsiness. We generally recommend taking it before going to bed at night. Patients with underlying heart disease and those who drive should take it with caution, especially those who take antihistamines during alcohol consumption to worsen cognitive and psychomotor disorders!" Can this medication be taken for a long time? Dr. Xu Haibo said that allergic rhinitis is generally divided into seasonal allergic rhinitis and perennial allergic rhinitis. "For the treatment of perennial allergies, we mainly use local medication and nasal spray. When the attack is severe, such as during seasonal changes, we recommend taking loratadine for a period of 2-4 weeks. After 2 weeks, allergic rhinitis generally improves slowly. If it improves, the medication should be slowly stopped and switched to local medication (nasal spray)." Zhang Yijin, Deputy Chief Physician of the Dermatology Department of the Third People's Hospital of Hangzhou, suggests that allergens should be screened first and contact with pollen and willow catkins should be avoided as much as possible. For example, when going out, you can wear masks and scarves, and try to wear them tightly. If willow catkins or other debris fall onto the skin, try not to rub or scratch them. You can wash them off with clean water. In addition, from 10am to 4pm is a high incidence period for willow catkins, and patients with allergic symptoms should try to avoid going out during this time period. You can choose to travel earlier, later, or after the rain. Zhang Yijin stated that it is safer to consult a doctor when taking it for a longer period of time. (Lai Xin She)
