Astelin: Uses, Dosage, Demographic, Side Effects, Interactions, and Generic Options Introduction Astelin is a highly effective nasal allergy medication that has been used for many years to relieve nasal congestion and other allergy symptoms. It is a prescription medication that is available in two forms: nasal spray and eye drops. The active ingredient in Astelin is azelastine hydrochloride, an antihistamine that reduces the effects of histamine in the body. Uses Astelin is primarily used to treat nasal symptoms of seasonal allergic rhinitis, such as runny nose, congestion, itchy nose, and sneezing. It can also be used to treat nasal symptoms of non-allergic rhinitis, such as congestion, runny nose, and post-nasal drip. In addition, it is sometimes prescribed for the treatment of ocular symptoms of allergic conjunctivitis, such as itching and redness. Dosage Astelin nasal spray is available in 137-microgram and 205-microgram strengths. The recommended dose for adults and children six years of age and older is two sprays per nostril twice daily, or one spray per nostril twice daily. For some patients, a lower dose may be sufficient. The recommended dose for children between two and six years of age is one spray per nostril twice daily. The recommended dose for children under two years of age has not been established. Demographic Astelin is safe and effective for use in adults and children over the age of six. It is not recommended for use in children under two years of age due to the lack of safety data. It is generally well-tolerated in both men and women, and has not been found to have any significant differences in efficacy or safety between genders. Side Effects The most common side effects of Astelin include bitter taste, headache, drowsiness, and nasal irritation or dryness. These side effects are typically mild and resolve on their own within a few days of starting treatment. However, some patients may experience more severe side effects, such as nosebleeds, eye pain, blurred vision, or severe allergic reactions such as anaphylaxis. Interactions Astelin may interact with other medications, such as beta-blockers, antihistamines, and antidepressants. Patients should inform their healthcare provider of all medications they are taking to avoid potential drug interactions. Generic Options Astelin is available as a brand name medication and as several generic options, including azelastine, Astepro, and Optivar. Generic medications are approved by the U.S. Food and Drug Administration (FDA) and have the same active ingredients, dosage form, and strength as the brand-name medication.
