The duration and dosage of Ebastine is usually chosen according to the patient’s condition in the clinic. There is no clear limit to the duration of Ebastine, but it still depends on the patient’s condition. Ebastine tablets are antihistamines with a wide range of clinical applications, mainly for the treatment of allergic diseases, such as atopic dermatitis, acute and chronic urticaria, drug rash, solar dermatitis, allergic rhinitis, allergic conjunctivitis, etc.; they can also be used for skin itching caused by non-allergic diseases, such as psoriasis vulgaris, pityriasis rosea, neurodermatitis, seborrheic dermatitis, etc. If the patient’s symptoms are mild, the condition can be significantly relieved usually after one week of continuous application under the guidance of physicians. If the patient’s symptoms are still not significantly relieved after one week of application of Ebastine tablets, it is recommended that the patient stop using this drug in a timely manner, follow up as soon as possible, and adjust the medication regimen under the guidance of a physician. In addition, if patients experience adverse reactions such as swelling, rash, nausea, vomiting, tachycardia, drowsiness, dizziness, headache, etc. during the application of this drug, they should temporarily discontinue this drug and promptly consult a doctor to assess their condition.
