How many days can Loratadine tablets be taken at most?

The duration of Loratadine tablet treatment generally depends on the patient's specific condition. Clinically, Loratadine tablets are primarily used to treat allergic diseases such as allergic rhinitis, allergic conjunctivitis, and acute or chronic urticaria. The details are as follows: 1. **Allergic Rhinitis**: If a patient is taking Loratadine tablets to treat allergic rhinitis, the usual course of treatment is about 7 days. If symptoms are mild, the patient may stop taking the medication after about 3 days. 2. **Allergic Conjunctivitis**: For treatment of allergic conjunctivitis, patients are generally advised to take the medication for about one week. However, patients should avoid taking the medication for more than 2 weeks to prevent potential adverse reactions. 3. **Acute or Chronic Urticaria**: For patients with acute urticaria, it is recommended to discontinue the medication after 2–3 days of use. However, if the patient suffers from chronic urticaria, it is recommended to continue the medication for a duration of 1 month.
