Can levocetirizine hydrochloride capsules be taken long-term?

Generally, levocetirizine hydrochloride capsules are not recommended for long-term use, as they may cause physical discomfort. The specific analysis is as follows:

Levocetirizine hydrochloride capsules are a commonly used antihistamine, primarily indicated for the treatment of allergic conditions such as seasonal allergic rhinitis, perennial allergic rhinitis, and chronic idiopathic urticaria. Long-term use of levocetirizine hydrochloride may lead to central nervous system depression, manifesting as drowsiness, fatigue, dizziness, and headache. Persistent occurrence of these symptoms may reduce a patient's alertness and reaction ability, thereby increasing the risk of accidents.

Prolonged medication use may also cause damage to the liver and kidneys. As the primary organs responsible for drug metabolism and excretion, the liver and kidneys may experience increased workload with long-term drug use, potentially leading to organ dysfunction. Additionally, long-term use may lead to drug tolerance. When pathogens are repeatedly exposed to the same medication, they may gradually adapt and become less sensitive, reducing the drug's effectiveness. Moreover, when levocetirizine hydrochloride is taken concurrently with other medications, chemical or physiological interactions may occur, potentially affecting therapeutic efficacy or increasing the risk of adverse reactions.

In daily life, it is important to maintain a balanced diet, consume adequate vitamins and proteins, and eat plenty of vegetables and fruits, which helps enhance immune function and promote overall health.
