What are the side effects of long term use of Flonase?

4 min read

While Flonase (fluticasone propionate) is generally considered safe and effective for allergy symptom management, with a 6-month study finding no systemic side effects with standard doses, it is important to be aware of the potential side effects of long term use of Flonase. These risks range from common nasal irritation to rarer but more serious systemic concerns like vision problems or adrenal suppression.

Quick Summary

Long-term use of Flonase carries potential side effects, from common local issues such as nosebleeds and irritation to less frequent systemic problems like cataracts, glaucoma, adrenal suppression, and slowed growth in children.

Key Points

  • Local Side Effects: Common local effects of long-term Flonase use include nosebleeds, nasal irritation, dryness, and in rare cases, ulcers or septal perforation.

  • Rare Systemic Risks: Although uncommon, prolonged and high-dose use of Flonase can lead to systemic side effects like adrenal suppression, weakened immune function, cataracts, and glaucoma.

  • Pediatric Growth Concerns: A significant concern for long-term use in children is a potential reduction in growth velocity, requiring regular medical monitoring.

  • Proper Use is Key: Minimizing risks involves using the lowest effective dose for the shortest duration necessary, especially for over-the-counter use.

  • Regular Monitoring: Regular eye exams are recommended for long-term users, and any significant vision changes should be reported to a doctor immediately.

  • Manage Nasal Irritation: Using a saline spray before Flonase application or a humidifier can help manage nasal dryness and prevent nosebleeds.

Understanding Flonase and Long-Term Use

Flonase, the brand name for the corticosteroid fluticasone propionate, is a popular over-the-counter and prescription nasal spray used to treat symptoms of seasonal and year-round allergies. It works by reducing inflammation in the nasal passages caused by allergens, alleviating congestion, sneezing, and runny nose. For many individuals, Flonase is a safe and effective treatment when used as directed for short periods. However, when used for extended durations, particularly at higher-than-recommended doses, the potential for long-term side effects increases. Medical experts emphasize using the lowest effective dose for the shortest amount of time, especially for children. This awareness is crucial for ensuring the benefits of the medication continue to outweigh any potential risks.

Common and Rare Side Effects of Prolonged Flonase Use

Common Local Nasal Effects

Over time, consistent use of Flonase can lead to several localized side effects within the nasal passages. These are generally considered less severe than systemic issues and are often manageable with proper use.

  • Nosebleeds and irritation: Long-term use can thin the nasal lining, making it more susceptible to irritation and causing nosebleeds (epistaxis). Using a saline spray before Flonase or applying a nasal moisturizer can help mitigate this.
  • Nasal septal perforation: In very rare cases, the delicate tissue separating the nostrils can develop a hole (perforated septum). This is often linked to improper spraying technique or prior nasal injury.
  • Thrush (candidiasis): An overgrowth of yeast can occur in the nose or throat, appearing as white patches. This is a fungal infection that can happen with prolonged steroid use, which can suppress the localized immune response.
  • Sores and slow wound healing: The anti-inflammatory nature of the medication can slow the healing of any wounds or sores inside the nose.

Rare Systemic Side Effects

Because only a small amount of fluticasone is absorbed systemically, serious side effects are rare when the medication is used at standard doses. However, in sensitive individuals or with excessive use, systemic absorption can increase the risk of more serious issues.

  • Adrenal suppression: The adrenal glands produce the steroid hormone cortisol. Exogenous steroids like fluticasone can suppress the body's natural production, potentially leading to adrenal insufficiency if stopped suddenly. This is primarily a risk with excessive or prolonged use.
  • Cataracts and glaucoma: Long-term steroid use has been linked to eye conditions like cataracts (cloudy vision) and glaucoma (increased eye pressure). Regular eye exams are recommended for individuals on prolonged Flonase therapy.
  • Decreased bone mineral density: Glucocorticoids can decrease bone density over many years, increasing the risk of osteoporosis. This is more commonly associated with oral steroids, but prolonged use of nasal steroids may also carry a minimal risk.
  • Weakened immune system: Corticosteroids can suppress the immune system, making individuals more susceptible to infections. This is a rare risk with nasal sprays compared to oral steroids.

Comparison of Flonase Side Effects: Local vs. Systemic

To better understand the nature of the risks, here is a comparison of the more common local effects and the less frequent systemic effects associated with long-term Flonase use.

Aspect Local Long-Term Side Effects Systemic Long-Term Side Effects (Rare)
Examples Nosebleeds, nasal irritation, sores, candidiasis Adrenal suppression, cataracts, glaucoma, decreased bone density, growth effects in children
Frequency More common, often manageable Infrequent, especially at recommended doses
Causes Direct effect on nasal mucosa Minor systemic absorption of corticosteroid
Risk Factors Improper usage, pre-existing nasal conditions, high doses High doses, prolonged use, other corticosteroid use
Management Saline rinses, proper technique, temporary discontinuation Regular medical monitoring (eye exams, growth checks), dose adjustments, using lowest effective dose

Considerations for Children and Best Practices

Pediatric Concerns

A notable concern with prolonged intranasal corticosteroid use in children is potential slowed growth velocity. Some studies indicate this might be a temporary delay, with children eventually catching up on growth, but the long-term impact on final adult height is not yet fully understood. The FDA recommends that children between 4 and 11 years old not use over-the-counter Flonase for more than two months a year without consulting a pediatrician. Any child using Flonase for an extended period should have their growth monitored by a doctor.

Best Practices for Minimizing Risks

If long-term Flonase use is necessary, following these best practices can help mitigate potential side effects:

  • Use the lowest effective dose to control symptoms.
  • Consider taking occasional "drug holidays" if symptoms allow, under a doctor's supervision.
  • Use proper administration technique to ensure the spray is delivered correctly.
  • Use a saline nasal spray or rinse a few minutes before applying Flonase to help moisturize the nasal passages and reduce irritation.
  • If experiencing dry nose or irritation, consider using a humidifier.
  • Undergo regular eye exams if on prolonged therapy, especially with existing eye conditions like cataracts or glaucoma.
  • Discuss any changes in vision, unexplained fatigue, or persistent nasal issues with a healthcare provider immediately.

Conclusion

While Flonase is a highly effective treatment for allergy symptoms, understanding what are the side effects of long term use of Flonase is essential for making informed healthcare decisions. The majority of long-term users, particularly those following recommended dosages, do not experience serious issues. However, awareness of potential local effects, such as nosebleeds and irritation, as well as rarer systemic effects like adrenal suppression or vision changes, is important. Close medical supervision, especially for children, is crucial to manage and monitor for potential adverse effects. By using the lowest effective dose and following best practices, patients can maximize the therapeutic benefits while minimizing risks. Always consult with a healthcare provider regarding long-term use and any concerns that may arise.

Frequently Asked Questions

While many adults can safely use Flonase for long periods, it is best to use it for the shortest amount of time needed to control your symptoms. Over-the-counter labels recommend talking to a doctor if daily use extends beyond six months. A healthcare provider can help determine if continued use is appropriate.

Serious systemic side effects from long-term use of Flonase are rare, particularly when used at the recommended doses. The localized effects in the nose are more common and generally mild.

Prolonged use of Flonase, especially at higher-than-recommended doses, can rarely cause adrenal gland disorders and affect hormone production. This is not typically a concern with standard, recommended dosages, but a doctor should be consulted if signs of a hormonal disorder appear.

Long-term use of corticosteroid nasal sprays may increase the rare risk of developing cataracts or glaucoma. If you have pre-existing eye conditions or develop vision changes, you should consult an ophthalmologist.

To prevent nasal side effects like nosebleeds or irritation, use proper nasal spray technique, consider using a saline nasal rinse before Flonase, or use a humidifier. Consult a doctor if you experience persistent or severe symptoms.

Nasal corticosteroids like Flonase can slow a child's growth rate when used for extended periods. It is recommended that children between 4 and 11 not use OTC Flonase for more than two months a year without a doctor's approval, and a pediatrician should monitor their growth.

If you find you need to use Flonase daily for longer than 6 months, you should consult with a healthcare professional. They can assess your symptoms, monitor for side effects, and discuss the appropriate course of action.
