Flonase is the brand name for a line of nasal sprays used for airborne allergies such as hay fever and animal and dust allergies. Available products include Flonase Allergy Relief and Flonase Sensimist Allergy Relief. There are also children’s versions of both of these products. Flonase nasal sprays can help manage symptoms such as sneezing, nasal congestion, itchy and watery eyes, runny nose, and an itchy nose and throat.

Doctor’s advice

How does it work?

Flonase nasal sprays contain fluticasone, a type of medication known as a corticosteroid. It works by reducing inflammation in the nasal passages, the root cause of hay fever, and other airborne allergy symptoms. It does this because fluticasone is a manufactured version of a corticosteroid, a hormone that is produced naturally in our bodies. By having the same structure as corticosteroids in our bodies, it causes the same effect, in this case, reducing inflammation.

Flonase Sensimist nasal sprays are slightly better tolerated and are more effective against itchy, watery eyes.

How often should I use my Flonase nasal spray, and how many sprays should I use?

Using your Flonase nasal spray regularly each day will provide you with the maximum benefit, helping to prevent your symptoms before they occur.

How many sprays you should use depends on your age. Generally, to begin with, adults and children aged 12 years and above are recommended to use two sprays into each nostril once a day. Then once their symptoms are under control, they should try to reduce the dosage to one spray into each nostril once a day. Younger children are advised to use just one spray into each nostril once a day.

After seven days, if your symptoms do not improve or are still poorly controlled, you should speak with your doctor or pharmacist.

Also, you should speak with your doctor before using Flonase for longer than three months.

Who should not use Flonase nasal sprays?

As always, do not use the medication if you are allergic to any of the ingredients in it. Make sure you follow the age restrictions for the product.

You should speak with your doctor or pharmacist before using the medication if you are pregnant or breastfeeding or have any problems with your nose, such as an injury, infection, ulcers, or recent surgery.

Flonase nasal sprays can interact with other medications, such as HIV medications and other corticosteroids. If you take any prescription, over-the-counter or herbal medicines, ask your doctor or pharmacist to check if they are safe to take alongside Flonase.

Are there any side effects?

As with all medications, some people may experience side effects. If any side effects become bothersome, you should speak with your doctor or pharmacist. Some common ones can include nose bleeds, headache, sore throat, and nose burning or itching. Seek urgent medical advice if you develop any problems with your eyes, such as blurred vision, cloudy vision, or loss of vision.
