What is FLONASE and How Does it Work?

FLONASE is a medication that offers allergy relief for uncomfortable symptoms such as sneezing and an itchy nose. You apply it directly into your nose to block an allergic reaction.  FLONASE contains an anti-allergy ingredient called fluticasone propionate and is used as a nasal spray to relieve nose and eye-related allergy symptoms. FLONASE incorporates several inflammatory substances, including cytokines, histamine, tryptases, prostaglandins, chemokines, and leukotrienes to fight against allergy symptoms.

Read on to learn more about FLONASE and how to get it online.

When Do You Use FLONASE?

FLONASE helps to alleviate the discomfort of day-time and night-time symptoms and provides 24-hour relief of the following allergy symptoms:

FLONASE works best for allergy-related symptoms. If you have symptoms such as thick nasal discharge, pain in your face or in your ears, or you think that you may have a sinus infection, stop taking FLONASE and see your doctor to discuss your options for other appropriate medications.

How Long Does it Take FLONASE to Start Working?

FLONASE may provide relief after the first day of starting the medication. It should take full effect within three to four days with regular use once a day. During allergy season, it is recommended to use FLONASE once a day, every day to help relieve your allergy symptoms.

Are There Any Side Effects of FLONASE?

Most side effects of FLONASE are mild. The most common side effects of FLONASE include:

  • Sore throat
  • Sneezing
  • Sinus pain
  • Nosebleeds
  • Coughing
  • Headache
  • Nausea or vomiting
  • Back pain
  • White patches or sores inside your mouth or nose

You may have an adverse drug interaction with FLONASE if you are currently on Norvir or Nizoral. You can also experience increased side effects when taking either of these drugs with FLONASE.

In addition, in some cases FLONASE has been associated with allergic reaction symptoms such as a skin rash, facial swelling, itching, and anaphylaxis. If you experience any of these more serious symptoms, stop taking FLONASE and call you doctor immediately.


For adults, the recommended starting dosage of FLONASE is two sprays in each nostril once a day, for a total daily dose of 200 mcg. Consult your doctor to discuss a pediatric dosage of FLONASE.

How Do You Get FLONASE Online?

Getting FLONASE online starts with making an appointment with an online healthcare professional at a telehealth site like  

After you make an appointment, you will meet with your doctor via a video chat or phone call. You’ll discuss with your doctor your medical history and current allergy symptoms. Your doctor will carefully consider your situation and offer you treatment which may include a prescription to alleviate your allergy symptoms such as FLONASE. You can pick up your prescription at a pharmacy located near you.
