Quick Facts

• Both Flonase and Nasonex are used to treat nasal allergy symptoms.
• Flonase contains fluticasone propionate, while Nasonex contains mometasone furoate.
• Both are corticosteroid medications that reduce inflammation in the nasal passages.
• The onset of relief varies among individuals, typically starting within a few hours but may take several days to achieve full effectiveness.
• Common side effects include nasal irritation and headaches.
• Important interaction risks include concurrent use with strong inhibitors of the CYP3A4 enzyme.
• Flonase is available over-the-counter (OTC) in some countries, while Nasonex typically requires a prescription.
• Special caution is advised for pregnant or nursing women and children under 12, unless directed by a doctor.
• Immediate medical attention may be required for symptoms of a serious allergic reaction.

What They Are and How They Work

Both Flonase and Nasonex are part of a class of medications known as corticosteroids. These medications work by reducing inflammation in the nasal passages, thereby alleviating symptoms like congestion, runny nose, sneezing, and itching associated with allergic rhinitis.

Flonase contains the corticosteroid fluticasone propionate, while Nasonex contains mometasone furoate. These active ingredients help decrease inflammation and swelling in the nasal passages, improving airflow and symptom relief. They are both considered effective at controlling allergic symptoms when used regularly.

Indications / Uses

Both medications are primarily used to treat symptoms of allergic rhinitis, which can be seasonal or perennial (year-round). They help manage symptoms like:

• Nasal congestion
• Sneezing
• Runny nose
• Nasal itching

While both Flonase and Nasonex are approved for these uses, Nasonex is sometimes prescribed for the treatment of nasal polyps in adults, an off-label use for Flonase in some cases.

Dosage Forms and Typical Dosing Considerations

Both Flonase and Nasonex are available as nasal sprays. The specific dose may depend on the individual’s age and the severity of the symptoms. Typically, for adults, the dosing is one to two sprays in each nostril once daily according to the instructions on the packaging or the prescriber\’s directions.

Factors affecting dosing can include:
– Age: Pediatric use often requires adjusted dosing under medical supervision.
– Liver or Kidney Function: No major adjustments typically needed, but full disclosure of medical conditions to your healthcare provider is important.
– Pregnancy/Breastfeeding: Use only if the potential benefit justifies the potential risk to the fetus or infant.

How to Take It Correctly Step-by-Step

1. Shake the bottle gently before use.
2. Clear your nose by gently blowing to remove mucus.
3. Insert the applicator tip into one nostril, closing the other with a finger.
4. Breathe in slowly through your nose while pressing down on the applicator to release the spray.
5. Breathe out through your mouth, repeat in the other nostril if needed.
6. Wipe the applicator tip with a clean tissue and replace the cap.
7. Store as directed and avoid humidity or high temperatures.

If a dose is missed, use it as soon as you remember on the same day. Do not double doses.
