Astelin (Azelastine)
Astelin is a brand name for a nasal spray containing the active ingredient azelastine hydrochloride. It is an antihistamine that is used to relieve allergy symptoms, particularly those affecting the nose, such as sneezing, runny or stuffy nose, itching, and nasal congestion.
The mechanism of Astelin involves blocking the action of histamine, which is a chemical released by the body during an allergic reaction. By inhibiting histamine, medicine helps to alleviate the symptoms of allergic rhinitis, also known as hay fever.
Medicine is typically prescribed for seasonal allergies caused by outdoor allergens like pollen or for perennial allergies triggered by indoor allergens such as dust mites, pet dander, and mold spores.
Uses
As mentioned earlier, Astelin is primarily used to treat symptoms associated with allergic rhinitis. Here are some specific uses:
- Seasonal Allergic Rhinitis: Nasal spray is commonly prescribed to manage symptoms caused by seasonal allergies, such as hay fever, which is triggered by outdoor allergens like pollen from trees, grasses, and weeds. It helps alleviate symptoms like sneezing, runny or stuffy nose, itching, and nasal congestion.
- Perennial Allergic Rhinitis: Medicine can also be used for year-round allergies caused by indoor allergens, including dust mites, pet dander, mold spores, and other allergens commonly found in indoor environments.
- Allergic Conjunctivitis: In some cases, Astelin may also help relieve symptoms of allergic conjunctivitis, which affects the eyes and causes redness, itching, and watery eyes.
It's important to note that Astelin is a nasal spray and is designed for intranasal use only. It is not intended for use in the eyes or for treating other types of allergies or medical conditions.
