What medication should be taken for constant runny nose and tearing eyes?

Continuous runny nose and tearing may be treated with medications such as loratadine tablets, azelastine hydrochloride tablets, Fengre Ganmao Granules (wind-heat cold granules), compound pseudoephedrine hydrochloride sustained-release capsules, and sodium cromoglicate eye drops. If any adverse reactions occur after using these medications, it is recommended to seek medical attention promptly. Specific analysis is as follows:

1. Loratadine Tablets: Persistent runny nose and tearing may result from exposure to allergens causing an allergic reaction. Therefore, patients can take loratadine tablets under medical guidance. This medication works by blocking histamine receptors, thereby reducing allergic responses and alleviating associated symptoms.

2. Azelastine Hydrochloride Tablets: This is an H1 receptor antagonist commonly used to treat conditions such as allergic rhinitis and urticaria. The aforementioned symptoms may also be caused by allergic rhinitis; thus, patients may follow medical advice to use this drug to relieve discomfort.

3. Fengre Ganmao Granules: Composed primarily of ingredients like Isatis root, forsythia, and chrysanthemum, this formulation has effects of dispelling wind, clearing heat, relieving sore throat, and detoxifying. It is commonly used to alleviate symptoms of wind-heat type colds, including fever, nasal congestion, tearing, and runny nose. Patients may use this medication as directed by a physician to relieve symptoms.

4. Compound Pseudoephedrine Hydrochloride Sustained-Release Capsules: Containing active ingredients such as pseudoephedrine and chlorpheniramine maleate, this medication helps reduce fever and relieve pain. When taken according to medical instructions, it can improve cold-related symptoms such as runny nose, sneezing, tearing, and nasal congestion.

5. Sodium Cromoglicate Eye Drops: An anti-allergic medication primarily used to prevent seasonal allergic conjunctivitis. When the eyes and nose are simultaneously exposed to allergens, patients may develop allergic conjunctivitis, leading to the above symptoms, possibly accompanied by sneezing and nasal congestion. Therefore, patients may use this medication under medical supervision to alleviate discomfort caused by allergic conjunctivitis.

In daily life, patients are advised to maintain a light diet, avoid staying up late, and practice good hygiene for the eyes and nose, which may help improve symptoms.
