What is Mometasone furoate Alter Generics?
Mometasone furoate Alter Generics nasal spray contains mometasone furoate, a medicine that belongs to a group of medicines called corticosteroids. When mometasone furoate is sprayed into the nose, it can help to relieve inflammation (swelling and irritation of the nose), sneezing, itching, and nasal stuffiness or runny nose.
What is Mometasone furoate Alter Generics used for?
Hay fever and perennial rhinitis
Mometasone furoate Alter Generics is used to treat the symptoms of hay fever (also known as seasonal allergic rhinitis) and perennial rhinitis in adults and children aged 3 years and older.
Hay fever, which occurs at certain times of the year, is an allergic reaction caused by breathing in pollen from trees, grasses, weeds, and also mold and fungus spores. Perennial rhinitis occurs throughout the year and the symptoms can be caused by sensitivity to a variety of things including house dust mites, animal hair (or dander), feathers, and certain foods. Mometasone furoate Alter Generics reduces the inflammation and irritation of your nose and thereby relieves sneezing, itching, and nasal stuffiness or runny nose caused by hay fever or perennial rhinitis.
Nasal polyps
Mometasone furoate Alter Generics is used to treat nasal polyps in adults aged 18 years and older.
Nasal polyps are small growths in the lining of the nose and usually affect both nostrils. Mometasone furoate Alter Generics reduces the inflammation in the nose, causing the polyps to shrink gradually, thereby relieving nasal stuffiness that can affect your breathing through your nose.
Do not use Mometasone furoate Alter Generics
