Get Astelin Online

Astelin is a prescription nasal spray containing azelastine, a second-generation antihistamine. It blocks H1 histamine receptors in the nasal lining, reducing sneezing, itching, runny nose, and congestion caused by allergic rhinitis.

The typical adult dose is two sprays in each nostril twice daily. You should prime the pump before first use and after extended periods of non-use. Avoid spraying into the eyes. Blow your nose gently before each dose for best results.

Many patients notice symptom improvement within 15 to 30 minutes of the first dose. Full therapeutic benefit is generally seen with consistent use over several days.

The most common side effects include a bitter taste after administration, drowsiness, headache, nasal burning or stinging, and nosebleeds. Bitter taste can often be reduced by keeping your head upright after spraying and breathing through your mouth briefly.

Yes. Azelastine can cause sedation in some patients, particularly when combined with alcohol or other central nervous system depressants. Use caution when driving or operating machinery until you know how it affects you.

Yes. Astelin is FDA approved for both seasonal allergic rhinitis and perennial (year-round) allergic rhinitis in adults. Your physician will confirm which indication applies to your symptoms during the evaluation.

Astelin can be used alone or in combination with an intranasal corticosteroid such as fluticasone. Combining the two may provide greater symptom relief than either agent alone. Always inform your physician of all current medications to avoid interactions.
