Flonase is a seasonal and year-round allergy over the counter (OTC) medication that is sold as a nasal spray. It contains fluticasone propionate. This is a corticosteroid that can relieve allergic and non-allergic nasals symptoms by blocking the effects of substances that can cause allergies, like pollen, dust mites, mold and pet dander. It can also reduce swelling.

It can provide relief from the most common nasal symptoms such as:

  • Stuffy nose
  • Runny nose
  • Itching
  • Sneezing

In addition, it can help to alleviate allergy eye symptoms like itchy, watery eyes.

Flonase Helps to Block 6 Allergic Substances

The makers of Flonase claim that this product can provide “more complete allergy symptom relief” because it can supposedly block six allergic substances compared to the only one allergic substance that is blocked by most allergy pills.

According to the official website, Flonase products act on more than one inflammatory substance and not just on histamine, which is typically the only allergic substance blocked by the most common OTC allergy pills. Other substances it blocks include: prostaglandins, cytokines, chemokines, leukotrienes and tryptases.

That being said, it should be noted that Flonase does not typically work immediately. It usually takes several days for it to reach its maximum effectiveness. Since this is the case, it is important to take this nasal spray as directed, which is typically once a day, every day, during allergy season or as directed by your healthcare provider.

Common Side Effects

While most people can take Flonase safely without experiencing adverse effects, the following are the most common side effects associated with Flonase:

  • Burning
  • Dryness
  • Crusting
  • Irritation inside the nose
  • Occasional nose bleeds
  • Headaches

Although serious side effects are not common when taking this allergy medication, you should discontinue use and seek medical attention if you experience more serious side effects, such as difficulty breathing, unusual tiredness or weakness, blurred vision or changes in vision, severe allergic reaction.

It should also be noted that Flonase may not be an ideal allergy reliever if you suffer from certain medical conditions, such as ocular hypertension or glaucoma, as intranasal steroids may increase intraocular pressure (IOP) in individuals with these conditions.

This is especially important if you have an existing medical condition, are currently taking other medications, are pregnant or nursing, or plan to use this product long term.
