What medication should I take if I'm allergic to locust blossoms?

Generally, allergic reactions to locust flowers can be treated with medications such as Loratadine Tablets, Cetirizine Hydrochloride Tablets, Ebastine Tablets, Montelukast Sodium Tablets, and Ketotifen Fumarate Tablets under a doctor's guidance. If discomfort occurs, prompt medical attention should be sought. The details are as follows:

1. Loratadine Tablets

A second-generation long-acting antihistamine that works by selectively antagonizing peripheral H1 receptors to inhibit histamine release. It is suitable for treating mild to moderate allergic reactions caused by locust flowers, such as rashes, itching, and nasal symptoms. It has no significant central sedative effects and is suitable for daytime use.

2. Cetirizine Hydrochloride Tablets

A second-generation antihistamine with a mechanism of action similar to loratadine. It effectively relieves itching and urticaria and can also inhibit eosinophil chemotaxis. It is suitable for acute allergic reactions. Some patients may experience mild drowsiness; therefore, it is recommended to take it before bedtime.

3. Ebastine Tablets

Relieves allergy symptoms by blocking histamine H1 receptors. Its effects can be maintained with once-daily dosing and are suitable for severe allergic reactions. It has minimal inhibitory effects on the central nervous system and is appropriate for patients needing to remain alert.

4. Montelukast Sodium Tablets

A leukotriene receptor antagonist that alleviates nasal congestion, asthma, and skin swelling caused by locust flower allergies by inhibiting leukotriene-mediated inflammatory responses. It is especially suitable for patients with concurrent respiratory symptoms.

5. Ketotifen Fumarate Tablets

Exerts dual effects of histamine H1 receptor antagonism and inhibition of allergic mediator release. It is effective for allergic rhinitis and urticaria but may cause side effects such as drowsiness and dry mouth. It is suitable for patients with mild to moderate allergies experiencing prominent nighttime symptoms.

Pregnant women, nursing mothers, and individuals with impaired liver or kidney function should adjust the dosage or choose alternative medications under medical supervision.
