FLONASE, an over-the-counter nasal corticosteroid spray, is a highly effective treatment for seasonal and year-round allergies. Its active ingredient, fluticasone, works by reducing inflammation in the nasal passages to relieve symptoms like sneezing, itchy eyes, and nasal congestion. While many people use it daily without issues, some individuals may experience side effects. Understanding these potential reactions and how to manage them is key to a positive treatment experience.
Common Side Effects of FLONASE
For many users, side effects are mild and manageable. The most frequently reported issues are related to the local application of the nasal spray. These include:
- Headache: This is one of the most common side effects reported by FLONASE users, though it is more prevalent at higher dosages.
- Nasal Irritation or Burning: The sensation of dryness, burning, or stinging in the nose is a common local effect, potentially caused by the propellant or direct contact with nasal tissue.
- Nosebleeds (Epistaxis): Nosebleeds can occur, especially with long-term use, as the medication can thin the delicate blood vessels in the nasal passages.
- Sore Throat and Cough: If the medication drips down the back of the throat, it can cause a sore throat, dry throat, or coughing.
- Nausea and Vomiting: Some users may experience an upset stomach, often caused by the medication draining into the throat and being swallowed.
- Unpleasant Taste or Smell: A change or loss in the sense of taste and/or smell is also possible.
How to Minimize Common FLONASE Side Effects
Proper administration can significantly reduce the risk and severity of these common side effects. Following these steps can help:
- Use the correct spraying technique: When spraying, aim the nozzle toward the outer wall of the nostril, away from the nasal septum (the cartilage dividing the nose). This helps prevent damage and reduce the risk of nosebleeds.
- Rinse your mouth: To prevent sore throat and an unpleasant taste, rinse your mouth with water or gargle after using the spray.
- Use a saline spray: Using a saline nasal spray or rinse a few minutes before FLONASE can help moisten the nasal passages and reduce irritation and nosebleeds.
- Stay hydrated: Drinking plenty of fluids can help with headaches and general discomfort.
- Use a humidifier: In dry climates or during winter, a humidifier can help prevent nasal dryness.
Less Common and Serious Side Effects
While rare, it is important to be aware of potentially more serious side effects. If you experience any of the following, contact your healthcare provider immediately:
- Oral or Nasal Thrush: A fungal infection (Candida) can develop in the nose or mouth, appearing as white patches.
- Nasal Ulcers or Perforation: Open sores or damage to the nasal septum can occur. A persistent whistling sound when breathing can be a sign of a perforated septum.
- Eye Problems: Long-term corticosteroid use may rarely lead to cataracts or glaucoma. Regular eye exams are recommended for long-term users, especially those with existing risk factors.
- Slowed Growth in Children: Intranasal corticosteroids may cause a reduction in growth velocity in children. Pediatricians should monitor the growth of children using these medications long-term.
- Allergic Reactions: Severe allergic reactions (anaphylaxis) are extremely rare but possible. Symptoms include rash, swelling of the face or tongue, and trouble breathing.
FLONASE vs. Other Nasal Sprays: Side Effect Comparison
Choosing between different nasal corticosteroids can be difficult, as many share similar side effect profiles. Here is a comparison of FLONASE (fluticasone) with another popular option, Nasacort (triamcinolone).
| Side Effect | FLONASE (Fluticasone Propionate/Furoate) | Nasacort (Triamcinolone) | Key Takeaway |
|---|---|---|---|
| Headache | Common | Common | Both can cause headaches, but higher doses of Flonase may increase risk. |
| Nasal Irritation | Common, though Flonase Sensimist may be less irritating than original Flonase. | Common, but is alcohol-free which may be less drying for some. | Formulation differences may impact irritation levels for individuals. |
| Nosebleeds | Common, especially with long-term use. | Common. | Both carry a risk of nosebleeds, with proper technique being essential for both. |
| Sore Throat | Common. | Common. | Caused by post-nasal drip for both; rinsing is a good preventative measure. |
| Oral/Nasal Thrush | Rare, but possible with long-term use. | Rare. | Fungal infection risk is present for both; practice good hygiene. |
Special Considerations for Long-Term FLONASE Use
Many individuals can use FLONASE on a daily basis for extended periods safely. However, prolonged use, especially at higher doses, can increase the risk of certain side effects. Concerns include nasal ulcers, a higher risk of infections due to immunosuppression, and hormonal changes (adrenal suppression), though the latter is primarily associated with high-dose or systemic steroid use. It is recommended for adults using FLONASE for more than six months, and children using it for more than two months per year, to consult a healthcare provider for monitoring.

Conclusion
FLONASE is an effective and generally well-tolerated treatment for allergy symptoms. The most common side effects—including headaches, nasal irritation, and nosebleeds—are often mild and can be managed with proper spray technique and hydration. While serious side effects are rare, it is important to be aware of them, especially with long-term use. By understanding the potential side effects and practicing careful usage, individuals can safely use FLONASE to manage their allergy symptoms and achieve relief. Always consult a healthcare provider with any persistent or concerning side effects.
