Sudafed vs Nasonex

Listen to the article instead of reading through it.


For individuals with allergic rhinitis, sinus congestion or other types of nasal discomforts, certain drugs that reduce inflammation and alleviate symptoms can help in managing these conditions. Sudafed and Nasonex are two such medications commonly prescribed for these issues. They each work differently but both have proven effective in providing relief from the uncomfortable symptoms associated with nasal allergies or colds. Sudafed is a decongestant that works by narrowing the blood vessels to decrease swelling and congestion. On the other hand, Nasonex is classified as a corticosteroid which functions by reducing inflammation within the nasal passages.

What is Sudafed?

Pseudoephedrine (the generic name for Sudafed) was a notable advancement in the class of decongestants intended to provide relief from nasal congestion due to colds, allergies or sinus infections. Pseudoephedrine operates by constricting blood vessels in the nasal passages, which results in reduced inflammation and congestion. It's an over-the-counter medication available in both tablet form and liquid.

On the other hand, Mometasone Furoate (Nasonex) is a corticosteroid utilized mainly for its powerful anti-inflammatory effects. Approved by the FDA in 1997, Nasonex works differently than Sudafed; it reduces swelling and inflammation within nasal passages over time rather than providing immediate relief. This makes it an excellent choice for managing seasonal or perennial allergic rhinitis symptoms but less useful for sudden onset of symptoms.

While both medications work towards alleviating similar symptoms, they do so through different mechanisms and with different side effect profiles. Nasonex may cause mild nosebleeds or headaches whereas Sudafed could potentially lead to restlessness or trouble sleeping due to its stimulant properties.

What conditions is Sudafed approved to treat?

Sudafed and Nasonex are both approved for the treatment of various nasal conditions:

  • Sudafed is used to relieve congestion due to common cold, flu, hay fever or other respiratory allergies.
  • Nasonex, on the other hand, is a prescription medication that treats symptoms of seasonal or year-round allergies including nasal congestion. It's also approved for preventing nasal polyps from returning after surgery to remove them.

How does Sudafed help with these illnesses?

Sudafed works to relieve nasal congestion by constricting the blood vessels in the nasal passages. It does this through its active ingredient, pseudoephedrine, which is a decongestant that reduces swelling and inflammation by narrowing these blood vessels, making it easier for air to flow through your nose. This action can provide relief from symptoms such as stuffy nose or sinus pressure.

On the other hand, Nasonex acts differently as it's a corticosteroid. It operates by reducing inflammation within the nasal passages over time, thus providing sustained relief from allergy symptoms like runny and stuffy noses. Mometasone furoate monohydrate is its active substance aiding in decreasing allergic reactions and related inflammation.

While both Sudafed and Nasonex can be used for similar issues, their mechanism differs significantly with Sudafed offering quick respite while Nasonex provides longer-term alleviation of symptoms.

What is Nasonex?

Nasonex is a brand name for mometasone furoate, which is a corticosteroid. It works by reducing inflammation in the nasal passages. This action helps to alleviate symptoms such as congestion, sneezing, and runny nose associated with seasonal or perennial allergies. Nasonex was first approved by the FDA in 1997.

Unlike Sudafed (pseudoephedrine), Nasonex does not act on adrenergic receptors to constrict blood vessels; instead it reduces the immune response causing the allergic reaction. Due to its localized activity within the nasal passages, systemic side effects are less common than those seen with oral decongestants like Sudafed. Side effects may include headache, viral infection, sore throat and coughing; however these are generally mild compared to potential cardiovascular issues linked with pseudoephedrine.

Mometasone furoate can be beneficial for patients suffering from hay fever or other allergy symptoms who do not respond well to typical over-the-counter decongestant drugs such as Sudafed.

What conditions is Nasonex approved to treat?

Nasonex, a prescription nasal spray, is approved for use in managing symptoms associated with:

  • Seasonal and perennial allergic rhinitis
  • Nasal polyps This corticosteroid medication helps reduce inflammation and swelling inside the nose, providing relief from congestion, sneezing, itching or a runny nose.

How does Nasonex help with these illnesses?

Corticosteroid is a hormone which also acts as an anti-inflammatory agent, and plays roles in many processes in the body, affecting immune response, metabolism control and stress reactions. Similar to how norepinephrine prepares the body for action under stress, corticosteroids prepare the body to fight inflammation induced by allergies or other conditions. Nasonex works by delivering mometasone furoate, a synthetic corticosteroid that reduces swelling and inflammation in the nasal passages thereby alleviating symptoms of allergic rhinitis such as runny nose, sneezing and itchy nose. Its localised action on glucocorticoid receptors within nasal tissues may also contribute to its effectiveness as an allergy treatment. Since it does not significantly affect systemic circulation after application compared to oral decongestants like Sudafed (pseudoephedrine), it is often prescribed when a patient needs long-term management of their allergy symptoms or has contraindications with pseudoephedrine such as hypertension.

How effective are both Sudafed and Nasonex?

Both pseudoephedrine (Sudafed) and mometasone furoate (Nasonex) are commonly used to alleviate symptoms of nasal congestion related to allergies or common cold, and they were approved by the FDA in 1976 and 1997 respectively. While they both address similar symptoms, their mechanisms of action differ significantly; Sudafed is a systemic decongestant that reduces swelling in the nasal passages by constricting blood vessels, while Nasonex is a topical corticosteroid that helps reduce inflammation within the nasal passages.

A double-blind clinical trial conducted in 2005 compared these two medications directly, finding them equally effective at relieving symptoms of seasonal allergic rhinitis. However, when considering side effects, there can be noticeable differences between the two. Sudafed may cause nervousness or insomnia due to its stimulant properties while Nasonex can potentially lead to nosebleeds or headaches.

In terms of overall use, Sudafed has been widely used for many years as an over-the-counter medication for temporary relief from sinus pressure and congestion whereas Nasonex requires a prescription but provides more focused treatment for ongoing conditions like chronic sinusitis or year-round allergies. Furthermore, because it's administered locally instead of systemically like Sudafed, Nasonex has less risk of causing systemic side effects such as increased heart rate or blood pressure.

While both drugs have proven effective at alleviating symptoms associated with nasal congestion whether acute or chronic in nature, your healthcare provider will likely consider factors such as duration and severity of your symptoms along with any potential risks before recommending one over the other.

At what dose is Sudafed typically prescribed?

Oral dosages of Sudafed range from 60-120 mg every 4 to 6 hours, but studies have indicated that 60 mg is generally sufficient for relieving nasal and sinus congestion in most people. Children aged between six and twelve may be started on a dose of 30-60 mg every four to six hours. In either population, the dosage can be increased after a few days if there is no response. The maximum dosage that should not be exceeded in any case is 240 mg/day for adults and adolescents over the age of twelve, while children under twelve should not exceed a maximum daily dose of 120mg. Nasonex, being a nasal spray rather than an oral medication, has different usage instructions - usually two sprays into each nostril once per day for adults and children aged twelve or over.

At what dose is Nasonex typically prescribed?

Nasonex treatment is typically initiated at two sprays in each nostril once daily. This dosage can then be adjusted to one spray in each nostril per day, depending on the individual's response and tolerance. For those with more severe symptoms initially, a higher dose of two sprays in each nostril twice daily may be recommended. However, after achieving adequate control of symptoms, it is advisable to reduce the dosage to one spray per nostril daily for maintenance therapy. Always remember that Nasonex should not exceed four sprays in each nostril per day and its usage must always follow your healthcare provider's instructions.

What are the most common side effects for Sudafed?

Common side effects of Sudafed include:

  • Nervousness
  • Restlessness or excitability (especially in children)
  • Dizziness, headache
  • Insomnia (trouble sleeping)
  • Fear or anxiety
  • Increased blood pressure

On the other hand, common side effects of Nasonex may include:

  • Headache
  • Viral infection (such as cold and flu)
  • Coughing
  • Nosebleeds
  • Sore throat -Signs of nasal irritation such as burning or stinging sensation.

It's important to mention that while both medications can provide relief from nasal congestion and related symptoms, their potential side effects differ due to their different active ingredients and mechanisms of action. Make sure to consult with your healthcare provider for which medication is best suited for you.

It's important to note these symptoms are rare but if you experience any of them after using Nasonex, seek medical help right away.

Contraindications for Sudafed and Nasonex?

Both Sudafed and Nasonex, along with most other nasal decongestants and corticosteroids, may worsen symptoms of certain conditions in some individuals. If you notice an increase in heart rate or blood pressure, experience sleeplessness or restlessness, please seek immediate medical attention.

Neither Sudafed nor Nasonex should be taken if you are taking monoamine oxidase (MAO) inhibitors used for treating depression. Always inform your healthcare provider about all the medications you are currently using; MAOIs will require a period of around 2 weeks to clear from the system to prevent hazardous interactions with Sudafed and Nasonex.

Sudafed can cause issues for people suffering from heart disease, high blood pressure, diabetes or thyroid disorders. It's also not recommended for men who have difficulty urinating due to an enlarged prostate gland.

Nasonex might result in nosebleeds if overused and it can occasionally slow growth rate in children so pediatric use must be monitored closely by a doctor. Always remember that drug choice depends on individual health status and response.

How much do Sudafed and Nasonex cost?

For the brand name versions of these drugs:

  • The price of 24 tablets of Sudafed (30 mg) averages around $10, which works out to approximately $0.40/day for a typical dosage.
  • The price of one Nasonex nasal spray canister (50 mcg/spray; 120 sprays per canister) is about $200, working out to approximately $1.67/day if you use two sprays in each nostril once daily.

Thus, if your recommended dose is higher for Sudafed or requires more than twice-daily usage, then brand-name Nasonex could be less expensive on a per-day treatment basis. Remember that cost should not be the primary consideration when determining which drug is right for you.

As far as generic versions are concerned:

  • Pseudoephedrine (active ingredient in Sudafed) costs vary by form and strength but it's generally quite affordable at around $0.20 to $0.60 per day depending on your dosage.
  • Mometasone furoate—the active ingredient in Nasonex—also has a generic version available with prices varying widely based on location and insurance coverage but expect it to be significantly cheaper than its branded counterpart.

Popularity of Sudafed and Nasonex

Pseudoephedrine, commonly known by the brand name Sudafed, was estimated to have been purchased over-the-counter by about 5 million people in the US in 2020. Pseudoephedrine accounted for approximately 30% of decongestant sales in the US. However, it appears to be one of the most-common "systemic" decongestants (not applied directly into the nose). The use of pseudoephedrine has been generally consistent since being placed behind pharmacy counters due to federal regulation in 2006.

Mometasone furoate nasal spray, including brand versions such as Nasonex, was prescribed to about 3 million people in the USA in 2020. In the US, mometasone accounts for just under 15% of intranasal corticosteroid prescriptions and around 7% overall among all types of medications used specifically for treating allergic rhinitis symptoms. The prevalence of mometasone has increased slightly over time as more patients switch from older intranasal corticosteroids like fluticasone propionate (Flonase) or triamcinolone acetonide (Nasacort) due to its potential benefits regarding fewer side effects.


Sudafed (pseudoephedrine) and Nasonex (mometasone) are two common medications used in the management of nasal congestion, often due to allergies or colds. They have established records of effectiveness, backed by numerous clinical studies demonstrating their greater efficacy compared to placebo treatments. These drugs work differently; Sudafed is a decongestant that shrinks blood vessels in the nasal passages, while Nasonex is a corticosteroid that reduces inflammation.

There may be instances where these medications are combined for more effective relief from symptoms but this should be done under careful consideration by a physician as there can also be contraindications between them.

Both Sudafed and Nasonex are available over-the-counter, though Sudafed's sales may be regulated due to it being an ingredient in illegal methamphetamine production. This accessibility represents significant cost savings especially for patients who must pay out of pocket.

The side effect profile is somewhat different between the two drugs with Sudafed potentially causing restlessness or sleep issues due to its stimulant nature whereas Nasonex might cause irritation at the application site or headaches. As with any medication treatment plan, patients should closely monitor their response when starting these treatments and seek medical help immediately if they notice any severe reactions or worsening symptoms.
