Zalastin nasal spray is used to treat the symptoms of allergic rhinitis, such as sneezing, runny nose, itching, and congestion. It works as an antihistamine, blocking the effects of histamine, a substance released by the body when exposed to allergens such as dust, pollen, or animal dander.
Zalastin is characterized by its rapid effect, helping to relieve symptoms within a short time after use. It can also be used in cases of seasonal or perennial rhinitis. It should be used according to the doctor's instructions and not exceed the specified dose to avoid side effects such as nasal irritation or a bitter taste in the mouth. It is recommended to shake the spray bottle well before use and to gently clean the nose to ensure the effectiveness of the medicine.
