Allergies are triggered when your immunity system erects needful defense against a foreign body. Such foreign substances are generally referred as allergens. Among the various types of allergies, a few widely triggered conditions are allergies experienced in nasal pathways; these are categorised as nasal allergies. The typical signs of such an allergy are sneezing, runny rose, stuffed nasal pathways, secretion of tears, itchiness, etc. Most nasal allergies are seasonal in nature while some are perennial. Seasonal ones are often triggered by pollen grains. On the other hand, perennial nasal allergies are outcomes of sensitivity to insects, mites or pets. Flonase is a drug commonly used for the treatment of nasal allergies. It is a good practice to know the side effects this drug may trigger.

When an allergen or an allergy-causing substance attacks your system, the immunity function gets ready to fight it. So, if an allergen is breathed-in, your immunity system will soon make needful amounts of antibodies and stimulants to defend you. In essence, these are protein-based compounds which make histamines; the function of histamines is to produce a few chemicals to trigger defensive reactions. Commonly experienced reactions include widening of blood vessels, internal swelling, stuffing your respiratory pathways, skin-based reactions like itchiness, hives, sores, etc. In general, your doctor may prescribe antihistamines to manage allergic reactions as well as to treat associated medical conditions.

Nasal allergies are mostly caused by allergic agents like tobacco smoke, dander of pets or saliva of cats, a few types of aromatic foods, strongly scented perfumes, dust as well as exhaust from cars or other vehicles. Intensive presence of pollen in the atmosphere is another cause for seasonal allergic reactions. Pollen grains from weeds and grasses are present during fall (autumn) and summertime. On the other hand, pollen of flowering plants is more pronounced during springtime. The common signs of nasal allergy are persistent spell of sneezing, runny nose or watery discharge from nose, itchy eyes, dryness of nasal skin, etc. You may also experience stuffed nose, soreness of throat, headache, tiredness, coughing and inflammation of facial as well as nasal region.

Use of flonase

Flonase is an anti-inflammatory drug. It belongs to a family of medications known as corticosteroids. Such drugs are used for treating allergies as well as a few skin conditions. Flonase is available as an over the counter (OTC) drug and also as a prescription medication. It is widely sold as a nasal spray; it can be applied or sprayed onto your nasal region. Its use can bring relief to allergic rhinitis and help manage symptoms such as runny nose, nasal itchiness and excessive episodes of sneezing.

It is not a good practice to blow the nose within 40 minutes after using flonase; such blowing can remove the active ingredients from the nasal region. In short, it can reduce the efficacy of your nasal spray. It is equally important to never share the pack with others. The odds of spreading infections are high when flonase is shared.

A few serious side effects of flonase

In some rare cases, flonase may also cause some serious or acute side effects.

A few other acute side effects are soreness of throat, formation of white-colored spots inside the nasal airways, discoloration of oral passage – especially, near your throat, etc.
