Summary
Azelastine is used to treat allergy symptoms, which include sneezing, runny nose, and itchy eyes. It is effective for allergic rhinitis, which is inflammation of the nasal passages due to allergies. Azelastine can be used alone or with other allergy medications for comprehensive relief.
Azelastine works by blocking histamines, which are chemicals in your body that cause allergy symptoms. It acts like a shield, preventing histamines from attaching to receptors, which reduces symptoms like sneezing and runny nose. This makes azelastine effective for treating allergic rhinitis.
Azelastine is usually taken as a nasal spray. For adults and children over 12, the typical dose is one or two sprays in each nostril twice daily. For children aged 6 to 11, it's one spray in each nostril twice daily. Always follow your doctor's specific dosing instructions.
Common side effects of azelastine include drowsiness, which means feeling sleepy, a bitter taste, and nasal irritation, which refers to discomfort in the nose. These effects are usually mild and temporary. If you notice new symptoms, talk with your doctor to determine if they are related to azelastine.
Azelastine may cause drowsiness, so avoid driving or operating heavy machinery until you know how it affects you. Alcohol can increase drowsiness. Avoid spraying into your eyes or mouth. If you experience severe allergic reactions, such as rash or difficulty breathing, seek medical help immediately.
