Flonase vs Phenylephrine
Introduction
For individuals grappling with nasal congestion, runny nose, or allergies, certain medications that modify the inflammation and constrict blood vessels in the nasal passages can help alleviate symptoms. Flonase and Phenylephrine are two such drugs commonly used to manage these conditions. They each work differently but both have a decongesting effect on patients suffering from allergic rhinitis or common colds. Flonase is a corticosteroid spray which affects inflammatory responses, reducing swelling and irritation in the nose. On the contrary, Phenylephrine is an oral tablet categorized as a decongestant that primarily works by constricting (shrinking) blood vessels in the nasal passages thereby relieving congestion.
What is Flonase?
Fluticasone propionate (the generic name for Flonase) was a significant advancement in the class of corticosteroid drugs, primarily used to manage symptoms associated with nasal congestion. Flonase was first approved by the FDA in 1990. It operates by reducing inflammation and swelling in the nasal passages, effectively alleviating symptoms such as stuffy or runny nose, sneezing, and itching. It is frequently prescribed to treat seasonal allergies like hay fever.
Phenylephrine is another drug that helps with nasal congestion but belongs to a different class of medications known as decongestants. Unlike Flonase which has an anti-inflammatory effect on your body's immune response, Phenylephrine works by narrowing blood vessels in the nasal passages - this results in reduced swelling and less production of mucus.
While both medications serve similar purposes, their mechanisms vary significantly which can lead to differences in side effects experienced by patients. For instance, Flonase may cause mild side effects like nosebleeds or throat irritation due its localized steroidal action whereas Phenylephrine could potentially elevate blood pressure levels since it affects systemic circulation.
What conditions is Flonase approved to treat?
Flonase is approved for the treatment of various conditions related to nasal symptoms, such as:
- Seasonal and perennial allergic rhinitis, typically known as hay fever
- Nonallergic rhinitis, a condition with symptoms similar to hay fever but not triggered by allergens
- Nasal polyps (in combination with another drug), which are soft growths inside your nasal passages
Phenylephrine on the other hand is primarily used as:
- A decongestant for relief from sinus congestion due to colds or allergies
- An active ingredient in eye drops for redness relief
How does Flonase help with these illnesses?
Flonase helps to manage nasal allergy symptoms by reducing inflammation in the nasal passages. It does this by blocking the effects of substances like histamine and cytokines, which are released during an allergic reaction and can cause swelling, redness, and itching. Histamines and cytokines act as messengers in the body that communicate information between cells about potential threats like allergens or infections. In individuals with allergies, these substances may be overproduced or overly sensitive leading to excessive inflammatory responses. Therefore, by inhibiting histamine and cytokine activity, Flonase can limit the negative effects of allergies such as sneezing, congestion, runny nose or itchy eyes.
On the other hand, Phenylephrine works differently from Flonase; it is a decongestant that shrinks swollen nasal tissues by constricting blood vessels in the nose through stimulation of alpha-adrenergic receptors on vascular smooth muscle. This reduces blood flow to your nasal passages allowing you to breathe more easily when dealing with colds or allergies.
What is Phenylephrine?
Phenylephrine is a selective alpha-1 adrenergic receptor agonist used primarily as a decongestant, as it can constrict the blood vessels in the nasal passages. By doing so, it reduces swelling and congestion, making it easier for people with colds or allergies to breathe through their nose. Phenylephrine was first approved by the FDA in 1976 and is available over-the-counter under various brand names such as Sudafed PE.
Unlike Flonase (fluticasone), which is a corticosteroid that works by reducing inflammation, phenylephrine does not have anti-inflammatory properties. This means its side effect profile will be different from that of corticosteroids like Flonase; for instance, phenylephrine does not cause dryness or irritation of the nasal passage nor affect sense of smell or taste. It's important to note though that while effective in relieving short term symptoms, Phenylephrine is less likely to help with long-term control of allergic rhinitis compared to medications like Flonase.
What conditions is Phenylephrine approved to treat?
Phenylephrine is an effective medication approved for the relief of:
- Nasal congestion due to common cold, allergies, or sinusitis
- Swelling of the blood vessels in the eyes caused by conditions such as conjunctivitis or allergic reactions It's worth noting that while Phenylephrine can provide much-needed relief from these symptoms, it is not recommended for people with certain health conditions like high blood pressure. Always consult a medical professional before starting a new medication regimen.
How does Phenylephrine help with these illnesses?
Phenylephrine is a decongestant that works similarly to norepinephrine, a neurotransmitter which also acts as a hormone in the body. Phenylephrine functions by constricting blood vessels in the nasal passages, effectively reducing swelling and congestion. This action can greatly alleviate symptoms of allergies or colds such as stuffy nose and sinus pressure. Unlike Flonase, which is a corticosteroid that reduces overall inflammation and immune responses, phenylephrine primarily targets the vascular system within your nasal passages. While both medications can be effective for relieving nasal congestion, phenylephrine might offer faster relief due to its direct vasoconstrictive effects but may have shorter duration of effect compared to Flonase.
How effective are both Flonase and Phenylephrine?
Both fluticasone propionate (Flonase) and phenylephrine have well-established histories of success in treating nasal congestion, albeit through different mechanisms. Fluticasone was first approved by the FDA in 1990, while phenylephrine has been available over-the-counter for many decades.
Fluticasone is a corticosteroid that works by reducing inflammation in the nasal passages. It is typically used daily to manage symptoms of allergic rhinitis, including sneezing, runny nose, and itchy or watery eyes. Phenylephrine is a decongestant that works by constricting blood vessels in the nasal passages. This reduces swelling and congestion but does not address underlying inflammation.
A 2004 review suggested that intranasal steroids such as fluticasone may be more effective than oral decongestants like phenylephrine at relieving symptoms of chronic rhinosinusitis[1]. However, both medications are generally considered safe and well-tolerated.
Phenylephrine can provide quick relief from acute nasal congestion due to colds or allergies but should not be used for longer than three days at a time due to risk of rebound congestion when use stops abruptly—a condition known as rhinitis medicamentosa[2]. In contrast, fluticasone's benefits may take up to several days to become apparent; however its effects last much longer and it can safely be used on an ongoing basis for management of chronic allergy symptoms.

At what dose is Flonase typically prescribed?
Flonase is typically dosed at two sprays per nostril once daily, equivalent to 100 mcg/day. However, some may find relief with only one spray per nostril (50 mcg). Children aged 4 and older can also use Flonase; the pediatric dose starts at one spray per nostril daily. If there is no response or if symptoms worsen after a week, dosage adjustments might be needed under medical supervision. Contrarily, Phenylephrine nasal drops or sprays are usually used every four hours as needed but should not be used more than six times in 24 hours due to the risk of rebound congestion.

In case you experience any of these signs after taking Phenylephrine, immediately seek medical attention. It's also important to remember that this drug may interact negatively with certain health conditions like diabetes and heart disease. Always consult with your healthcare provider before starting a new medication regimen.
Contraindications for Flonase and Phenylephrine?
Both Flonase and phenylephrine, like most nasal decongestants, may worsen symptoms of certain conditions in some people. For instance, if you notice your blood pressure rising or worsening glaucoma symptoms while taking these medications, please seek immediate medical attention.
Flonase and phenylephrine should not be taken if you are currently using or have recently used monoamine oxidase inhibitors (MAOIs). Always inform your physician about all the medications you are taking; MAOIs will require a period of about 2 weeks to clear from the system to prevent dangerous interactions with Flonase and phenylephrine.
How much do Flonase and Phenylephrine cost?
For the brand name versions of these drugs:
- The price for a 120 sprays bottle of Flonase (50 mcg/spray) averages around $22, which works out to about $0.18/day if used once daily per nostril.
- The price for Phenylephrine (10 mg), sold under the brand Sudafed PE, for a pack of 36 tablets is approximately $8, working out to between $0.20 and $1/day depending on frequency use.
Thus, if you are using Phenylephrine multiple times a day (i.e., every four hours as needed), then brand-name Flonase could be less expensive on a per-day treatment basis. Please note that cost should not be the primary consideration in determining which of these drugs is right for you.
For generic versions:
- Generic fluticasone propionate nasal spray can be found at prices ranging from about $12-$16 for 120 sprays bottle equivalent to roughly between $.10 - $.14/day.
- Generic phenylephrine comes in packs ranging from 24 up to hundreds with costs starting as low as $.05/tablet or even lower when bought in larger quantities.
So while both generic options present significant savings compared to their branded counterparts, it's crucial that efficacy and side effect profiles are considered along with cost when choosing between medications.
Popularity of Flonase and Phenylephrine
Fluticasone, available as Flonase among other names, is a nasal steroid spray that was estimated to be prescribed to about 12 million people in the US in 2020. Fluticasone accounted for approximately 13% of all prescriptions filled for nasal allergy drugs. The use of fluticasone has been generally rising since its approval by the FDA due to its effectiveness and low risk of systemic side effects.
On the other hand, Phenylephrine, which can be found under various brand names such as Sudafed PE or Nasop, is a decongestant used to relieve symptoms related to allergies or common colds like blocked nose or sinuses. It was prescribed to an estimated 4 million people in the USA during the same year. In terms of overall decongestant prescriptions across America, Phenylephrine holds just under 9%. Notably though unlike Flonase it's also readily available over-the-counter without prescription which might affect these figures significantly. The prevalence of phenylephrine usage has remained fairly stable over recent years.
Conclusion
Both Flonase (fluticasone) and Phenylephrine have been effectively used to manage the symptoms of allergic rhinitis, such as nasal congestion. They are supported by multiple clinical studies showing their effectiveness compared to placebo treatments. However, they operate through different mechanisms: Flonase is a corticosteroid that reduces inflammation in the nasal passages, while Phenylephrine works primarily as a decongestant by narrowing blood vessels in congested areas.
Flonase is often considered a first-line treatment for ongoing allergy symptoms due to its anti-inflammatory properties and sustained relief, whereas phenylephrine would typically be used short-term for immediate but temporary relief from nasal congestion.
Both medications come in generic forms which offer significant cost savings - an important factor for patients who must pay out of pocket. While both drugs can provide immediate relief upon use, full benefits may not be noticed until after several days with regular usage of fluticasone.
The side effect profiles are similar between the two drugs; although well-tolerated overall, both could potentially cause dryness or irritation within the nostril area. For either medication users should seek medical attention immediately if they experience severe side effects like difficulty breathing or irregular heartbeat.
