1. What is Nasometin and what is it used for

What is Nasometin?

Nasometin nasal spray contains mometasone furoate, which belongs to a group of medicines called corticosteroids. Mometasone furoate sprayed into the nose can help relieve inflammation (swelling and irritation of the nasal mucosa), sneezing, itching, and a feeling of nasal congestion or runny nose.

What is Nasometin used for?

Hay fever and perennial allergic rhinitis
Nasometin is used to treat the symptoms of hay fever (also known as seasonal allergic rhinitis) and perennial allergic rhinitis in adults and children aged 3 years and older.
Hay fever, which occurs several times a year, is an allergic reaction caused by inhaled pollen from trees, grasses, weeds, as well as molds and fungal spores. Perennial allergic rhinitis occurs throughout the year, and symptoms can be caused by hypersensitivity to various factors, including house dust mites, animal dander or skin, feathers, and some foods.
Nasometin reduces swelling and irritation of the nasal mucosa, thereby relieving sneezing, itching, and nasal congestion or runny nose caused by hay fever or perennial allergic rhinitis.
Nasal polyps
Nasometin is used to treat nasal polyps in adults aged 18 years and older.
Nasal polyps are small growths inside the nose, usually in both nostrils. Nasometin reduces inflammation, which causes the polyps to shrink gradually and relieve the feeling of nasal congestion, making it easier to breathe through the nose.
