Flonase: What It Is and How To Use It

Last update: 18 October, 2021

Flonase is a medicine that contains fluticasone propionate as the active ingredient. It’s a corticosteroid that has anti-inflammatory power.

This medicine is marketed in the form of a nasal spray. Flonase produces relief from the main allergy symptoms. Generally, they’re usually respiratory symptoms, especially from seasonal allergies.

How does it work?

Allergies happen when allergens enter through the nose. This process triggers a response from the immune system. When the release of different inflammatory substances is triggered, it causes different allergy symptoms.

The main characteristic of Flonase is that it can block the substances that cause inflammation. It can work on up to 6 of these inflammatory substances, including histamine.

In addition to histamine, Flonase works by blocking the following substances: prostaglandins, cytokines, tryptases, chemokines, and leukotrienes.

What is Flonase used for?

This medicine is for adults to relieve the symptoms of allergic rhinitis from pollen and other allergens that may be in the air. Some of these allergens are animal hair, dust mites, and fungal spores.

It helps with the symptoms that appear with allergic rhinitis and works to help sneezing, runny nose, congestion, and itchy and watery eyes. Its effect can last up to 24 hours, and it’s very easy to use.

You may see improvement in symptoms as early as the first application. However, you won’t reach maximum protection until after 3 or 4 days. Therefore, it’s important that you use Flonase regularly so that you can get the best possible relief from symptoms.

Flonase dosage and how to use it

In general, for adults, the recommended dose is two sprays per nostril, once a day, preferably in the morning.

In case you have more intense symptoms, you can use a second dose. However, only do this until you see improvement and for the shortest amount of time possible. Once you notice relief, use the regular dose again, just once a day. Always try to use the lowest dose possible.

Before using Flonase, the first thing you have to do is blow your nosethen shake the bottle and remove the cap. Then, place the tip in one of the nostrils and plug the other.

Tilt your head forward with the bottle straight, and breathe in slowly through your nose. As you breathe in, press the spray so that the product goes up your nose.

Then, breathe out through your mouth and repeat the steps for the second spray in the other nostril. When you finish, clean the top and put the protective cap on.
