Nasonex vs Claritin

Listen to the article instead of reading through it.


For patients dealing with allergies and the associated symptoms such as nasal congestion, sneezing, itching or runny nose, certain drugs can help in managing these discomforts. Nasonex and Claritin are two such medications that are commonly prescribed for allergy relief. They each have different mechanisms of action but both aim to alleviate allergic symptoms. Nasonex is a corticosteroid which works by reducing inflammation in the nasal passages thereby relieving congestion and related symptoms. On the other hand, Claritin falls under antihistamines category; it functions by blocking histamine, a natural substance produced during an allergic reaction hence mitigating typical allergy signs like sneezing, itching or runny nose.

What is Nasonex?

Mometasone (the generic name for Nasonex) was a significant advancement in the corticosteroid class of nasal sprays, leading to its FDA approval in 1997. It is primarily used to treat and prevent allergic rhinitis symptoms such as sneezing, itching, and congestion by reducing inflammation. Mometasone works by inhibiting the release of substances in the body that cause inflammation, effectively "trapping" them from causing discomfort.

On the other hand, Loratadine (the generic name for Claritin) belongs to a class of drugs known as antihistamines. It blocks histamine - a natural substance produced during an allergic reaction - thereby relieving allergy symptoms like watery eyes or runny nose.

While both medications are used to alleviate allergy symptoms, they work differently and have differing side effects. For example, Nasonex has minimal systemic absorption so it mainly affects only areas where it's applied with less impact on other parts of the body; this results in fewer overall side effects compared with oral medications like Claritin which circulate throughout your system.

What conditions is Nasonex approved to treat?

Nasonex is approved for the treatment of various allergic conditions:

  • Seasonal and perennial allergic rhinitis in adults and pediatric patients 2 years of age and older
  • Nasal congestion associated with seasonal allergic rhinitis in adult and adolescent patients 12 years of age and older
  • Prophylaxis of seasonal allergic rhinitis in adult and adolescent patients 12 years of age and older
  • Nasal polyps in patients 18 years of age or older.

How does Nasonex help with these illnesses?

Nasonex works to manage allergy symptoms by reducing inflammation in the nasal passages. It does this by mimicking corticosteroids, naturally occurring hormones that suppress immune responses and reduce inflammation. In response to allergens like pollen or dust mites, our immune system triggers an inflammatory response that can result in symptoms such as sneezing, itching, runny nose or congestion. Nasonex targets these symptoms directly at their source - your inflamed nasal tissue - and helps decrease swelling and irritation. Therefore, by reducing inflammation with Nasonex, you can limit the disruptive effects of allergies and help manage your condition more effectively.

On the other hand, Claritin combats allergies differently; it is an antihistamine that blocks histamines from binding to H1 receptors in the body thus preventing allergic reactions from happening in the first place. Histamine is a substance our bodies produce during an allergic reaction causing various symptoms including runny nose or watery eyes. By blocking these histamines with Claritin patients experience relief from allergy symptoms.

What is Claritin?

Claritin, also known by its generic name Loratadine, is an antihistamine that works by blocking the action of histamines, chemicals in your body involved in allergic reactions. It was first approved by the FDA in 1993. Unlike Nasonex which primarily acts as a steroid to reduce inflammation and swelling within nasal passages, Claritin does not exhibit this localized effect. Its lack of anti-inflammatory properties means that it's typically less effective at relieving symptoms like nasal congestion, but can still provide relief for other allergy symptoms such as runny nose, sneezing and itchy or watery eyes without causing drowsiness - a common side effect associated with some other antihistamines. This makes Claritin particularly beneficial for day-to-day management of chronic allergies where maintaining alertness throughout the day is important.

What conditions is Claritin approved to treat?

Claritin, a popular antihistamine medication, is approved for the management of:

  • Seasonal Allergic Rhinitis (SAR), also known as hay fever
  • Chronic Idiopathic Urticaria (CIU), which presents as unexplained and persistent hives.

It can also be used to relieve symptoms associated with perennial allergic rhinitis and other upper respiratory allergies such as sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat.

How does Claritin help with these illnesses?

Claritin, generically known as loratadine, is an antihistamine that works by blocking histamines in the body. Histamines are chemicals responsible for allergy symptoms such as runny nose, sneezing, itchy or watery eyes and itching of the nose or throat. By inhibiting these compounds, Claritin effectively reduces allergic reactions. It's widely used to alleviate symptoms of seasonal allergies like hay fever. Unlike Nasonex which is a nasal spray steroid specifically targeting nasal passages inflammation, Claritin has a broader action range and it can be taken orally making administration easier for some patients. While Nasonex might be prescribed for more severe cases involving nasal congestion caused by inflammation aside from allergies (such as polyps), Claritin often suffices in dealing with common allergenic reactions and may be combined with other medication if necessary.

How effective are both Nasonex and Claritin?

Both mometasone (Nasonex) and loratadine (Claritin) have a proven track record in alleviating symptoms of allergies, with their approval by the FDA coming within a decade of each other. Each drug acts on different pathways to control allergic reactions, hence they may be used under different scenarios or even together for comprehensive allergy management.

Direct comparison studies between mometasone and loratadine are somewhat limited due to their differing modes of action; however, it is generally accepted that both drugs provide effective symptom alleviation from common allergies such as hay fever. A 2004 study indicated that Nasonex was particularly effective at controlling nasal congestion - a symptom which antihistamines like Claritin sometimes struggle with.

A review published in 2001 reported that loratadine is an excellent first-line choice for managing seasonal allergic rhinitis due to its rapid onset of action, lack of drowsiness compared to first-generation antihistamines, and overall good safety profile. It has become one of the most commonly prescribed over-the-counter antihistamines worldwide. The typical dose for adults is 10 mg/day.

On the other hand, Nasonex - being a corticosteroid nasal spray - tends to be considered when symptoms persist despite initial treatment with oral antihistamines or if nasal symptoms predominate. Mometasone has been shown in numerous trials not only to alleviate sneezing, itchiness and runny nose but also effectively reduce inflammation associated with chronic sinusitis or polyps. Its effects might take longer than oral antihistamines but often last longer too making it ideal for long-term management strategies.

At what dose is Nasonex typically prescribed?

Nasonex is typically prescribed as two sprays in each nostril once daily, which amounts to about 100 mcg/day for adults and children age 12 years and older. For children aged between 2-11 years, the recommended dosage is one spray in each nostril per day or 50 mcg/day. The dose can be adjusted based on how well symptoms are controlled. On the other hand, Claritin comes as a tablet to take by mouth usually at a dose of 10 mg once daily for both adults and children above six years old. Children aged between two to five should use Claritin syrup with a typical dose of 5 mg once daily. In either case, it's important not to exceed the maximum recommended doses unless instructed by your healthcare provider.

At what dose is Claritin typically prescribed?

Claritin, also known as Loratadine, is typically started at a dosage of 10 mg per day for adults and children over six years old. This single-dose regimen can be taken once every 24 hours to control symptoms such as sneezing, itchy or watery eyes, and runny nose associated with seasonal allergies. For children between two to five years old, the dosage is usually reduced to 5mg/day. If there's no response or inadequate relief from allergy symptoms after several days of treatment at this dose level, it may be advisable to consult your doctor before making any changes in medication or dosage. The maximum daily dose should not exceed 10 mg unless otherwise directed by a healthcare provider.

What are the most common side effects for Nasonex?

Common side effects of Nasonex may include:

  • Headache
  • Viral infection (such as the common cold or flu)
  • Coughing
  • Nosebleeds
  • Sore throat, pharyngitis
  • Sinusitis and nasal irritation
  • Bronchitis
  • Upper respiratory tract infection

It's important to note that individual reactions can vary significantly when taking medication. If you experience any severe or persistent symptoms while using Nasonex, consult your healthcare provider immediately.

Are there any potential serious side effects for Nasonex?

In rare cases, Nasonex can cause potentially serious side effects. These may include:

  • Difficulty breathing or swallowing
  • Signs of an allergic reaction such as hives, facial puffiness, and swelling in your throat or tongue
  • Vision problems like blurred vision, eye pain or swelling
  • Fast heartbeat, chest tightness
  • Low potassium levels which could lead to unusual tiredness, muscle weakness or cramps
  • Nasal sores or white patches inside or around your nose

On the other hand Claritin is generally considered quite safe but it too has potential side effects including:

  • Allergic reactions characterized by difficulty breathing; swelling of your face, lips, tongue, or throat.
  • Rapid heart rate (tachycardia) -Dizziness -Liver problems - nausea, upper stomach pain that spreads to the back , fatigue and jaundice

If you experience any of these symptoms while using Nasonex or Claritin respectively ensure to consult with a healthcare provider immediately.

What are the most common side effects for Claritin?

While taking Claritin, individuals may experience some common side effects such as:

  • Dry mouth
  • Headache or fatigue
  • Nausea and stomach discomfort
  • Dizziness
  • Sleep problems (insomnia)
  • Sore throat or coughing Furthermore, in rare cases, it can cause a fast heartbeat. Although not usually associated with weight loss, increased urination or muscle/joint pain directly, if you notice any unusual symptoms while on Claritin it's important to discuss them with your healthcare provider.

Are there any potential serious side effects for Claritin?

Claritin, although generally well-tolerated, may present some undesirable side effects in rare cases. These include:

  • An allergic reaction which can be identified by hives, itching or a rash; fever; swollen glands; difficulty breathing or swallowing; and swelling of the face, lips, tongue or throat.
  • Unusual mood changes such as restlessness, nervousness or excitement that might cause insomnia.
  • Rapid heartbeat
  • Severe dizziness causing disorientation and confusion.
  • Problems with vision such as blurred sight and eye pain.

If you experience any of these symptoms after taking Claritin, it's recommended that you seek medical attention immediately.

Contraindications for Nasonex and Claritin?

Both Nasonex and Claritin, along with most other allergy medications, may worsen symptoms in some people. If you notice your allergies worsening or developing a reaction such as difficulty breathing, severe dizziness, or rash after taking either of these medications, please seek immediate medical attention.

Neither Nasonex nor Claritin should be taken if you are allergic to any of their ingredients. Always inform your physician about all the medications and supplements you are currently taking; certain drugs could interact negatively with Nasonex and Claritin. Furthermore, patients suffering from liver disease may require an adjusted dosage or special monitoring during treatment with these medicines.

It's also important to remember that while both drugs help manage allergy symptoms they work differently: Nasonex is a steroid nasal spray which reduces inflammation in the nose whereas Claritin is an oral antihistamine which counteracts the effect of histamine - a substance responsible for producing allergy symptoms. Your doctor can best advise on which medication would be more suitable based on your specific condition.

How much do Nasonex and Claritin cost?

For the brand name versions of these drugs:

  • The price for a 17g bottle of Nasonex (50 mcg) averages around $230, which works out to approximately $7.66 per day if you're using two sprays in each nostril once daily.
  • The price for a pack of 30 tablets of Claritin (10 mg) is about $20, working out to roughly $0.67 per day.

Thus, if you are using Nasonex at the typical dosage rate (i.e., two sprays in each nostril once daily), then brand-name Claritin is less expensive on a per-day treatment basis. However, cost should not be your primary consideration when determining which medication is right for your allergy symptoms and overall health needs.

For the generic versions of these medications, costs are significantly lower:

  • Mometasone furoate nasal spray (the generic version of Nasonex) can typically be found with prices ranging from about $60 to $100 for a 17g bottle depending again on the dose used it can range from an approximate cost between $2 and $3.33/day.
  • Loratadine (the generic form of Claritin) comes in packs as small as 10 up to bottles containing hundreds or even thousands costing anywhere from about $.04/tablet up to $.15/tablet making them considerably cheaper than their branded counterparts running at most around $.45/day if taking one tablet daily as directed by most physicians.

Popularity of Nasonex and Claritin

Mometasone, available under the brand name Nasonex among others, is a corticosteroid medication used to treat allergy symptoms like nasal congestion and sneezing. It was estimated to have been prescribed to about 3.5 million people in the US in 2020. Mometasone represented around 10% of all intranasal corticosteroid prescriptions in the US and has seen an increase in use since it became over-the-counter.

Loratadine, sold under brand names such as Claritin, is an antihistamine that treats similar allergy symptoms including runny nose and red/watery/itchy eyes; it was prescribed to approximately 7 million people in the USA during 2020. Loratadine made up just over 14% of oral antihistamine prescriptions within this period which has remained steady for at least a decade due largely to its effectiveness for most users and being non-drowsy compared with other first-generation antihistamines.


Nasonex (mometasone) and Claritin (loratadine) are both widely used for the management of allergy symptoms, with extensive clinical data supporting their efficacy over placebo treatments. In some cases, they may be used together to manage severe allergic reactions, but this should always be under a physician's guidance as combining drugs could lead to undesirable drug interactions. Nasonex acts primarily by reducing inflammation in the nasal passages, while Claritin operates mainly by blocking histamine receptors.

Nasonex is often considered a first-line treatment option for nasal allergies such as hay fever or perennial allergic rhinitis due to its targeted action. It can also prevent seasonal allergies when started one to two weeks prior to allergy season. On the other hand, Claritin is typically employed when systemic relief from multiple allergy symptoms -- like itching, runny nose and watery eyes -- is needed.

Both medications are available in generic form which translates into considerable cost savings particularly for patients who bear their own medical expenses. Both Nasonex and Claritin may require some time before effects become apparent.

The side effect profile between these two is quite different given their unique modes of action; however both medicines are generally well-tolerated. With Nasonex use there might be instances of nasal irritation or minor bleeding whereas with Claritin occasional drowsiness might occur despite being labeled non-drowsy. For both drugs it's important that patients monitor themselves closely especially during initial stages of usage and immediately seek medical help if any new or worsening conditions appear.
