Zyrtec D vs Nasacort Aq
Introduction
For patients dealing with allergies, certain drugs that block or limit the action of a compound in the body known as histamine can help mitigate allergic symptoms. Zyrtec D and Nasacort Aq are two such drugs commonly used for those purposes. They each act on different aspects of allergic reactions but both can provide relief from allergy-induced discomfort. Zyrtec D is an antihistamine combined with a decongestant, acting to reduce the effects of natural chemical histamine in the body while also shrinking blood vessels in the nasal passages. On the other hand, Nasacort Aq is classified as a corticosteroid and works by reducing swelling caused by allergy-triggered inflammation inside your nose.

What is Zyrtec D?
Cetirizine hydrochloride/pseudoephedrine hydrochloride (the generic name for Zyrtec D) is a combination of an antihistamine and a decongestant used to relieve allergy symptoms such as runny nose, sneezing, itchy or watery eyes, itching of the nose or throat, and nasal congestion. It was first approved by the FDA in 2001. Zyrtec D works by blocking histamines that cause allergies while also shrinking blood vessels in nasal passages to reduce swelling and congestion.
On the other hand, Triamcinolone acetonide (the generic name for Nasacort AQ) is a corticosteroid that prevents the release of substances in the body that cause inflammation. It's approved by FDA for over-the-counter use since 2013 primarily for treating nasal symptoms of seasonal and perennial allergic rhinitis.
While both medications are effective at relieving allergy symptoms, they work differently: Zyrtec D targets histamines directly while Nasacort Aq reduces general inflammation caused by an allergic response. This results in different side effect profiles; with sleepiness being more common with antihistamines like Zyrtec D whereas corticosteroids like Nasacort Aq may cause dryness or irritation inside your nose.
What conditions is Zyrtec D approved to treat?
Zyrtec D is approved for the treatment of various allergies and related symptoms:
- Seasonal allergic rhinitis, commonly known as hay fever
- Perennial allergic rhinitis, year-round allergies caused by dust mites, pet dander etc.
- Chronic urticaria (hives) It also provides relief from nasal congestion due to common cold or other respiratory allergies.
On the other hand, Nasacort AQ is specifically approved for:
- The treatment of nasal symptoms of seasonal and perennial allergic rhinitis in adults and children 2 years of age and older.
How does Zyrtec D help with these illnesses?
Zyrtec D helps to manage allergies by blocking the effects of histamine, a chemical that is released in response to an allergen. It combines an antihistamine (cetirizine) with a decongestant (pseudoephedrine). The cetirizine component works by binding to histamine receptors in the body, thus preventing them from causing symptoms such as sneezing, itching, and watery eyes. Pseudoephedrine reduces congestion by narrowing blood vessels in the nasal passages.
On the other hand, Nasacort Aq manages allergy symptoms through its active ingredient triamcinolone acetonide - a corticosteroid. This substance works primarily by reducing inflammation and suppressing immune responses that lead to allergic reactions. Triamcinolone acetonide can decrease swelling and mucus production within nasal passages which often results in relief from stuffiness or congestion.
Both Zyrtec D and Nasacort Aq are effective for allergy management but work via different mechanisms and may have different side-effect profiles.
What is Nasacort Aq?
Nasacort AQ is a brand name for triamcinolone acetonide, which is a corticosteroid. It works by reducing inflammation in the nasal passageways and has been shown to treat symptoms such as sneezing, itching, and congestion associated with seasonal and perennial allergic rhinitis. Triamcinolone acetonide was approved by the FDA in 1975. Unlike decongestant antihistamines like Zyrtec-D (Cetirizine/Pseudoephedrine), Nasacort AQ does not have an immediate action on histamine but instead reduces overall inflammation over time. This means that its side-effect profile differs from that of decongestants; it's less likely to cause insomnia or jitteriness (common side effects of decongestants), but may take longer to provide relief. The anti-inflammatory effect can be beneficial especially for individuals who do not respond well to "typical" over-the-counter allergy drugs such as Zyrtec-D.
What conditions is Nasacort Aq approved to treat?
Nasacort AQ is FDA-approved for the management of:
- Seasonal Allergic Rhinitis (SAR), also known as hay fever
- Perennial Allergic Rhinitis (PAR), year-round allergies caused by indoor allergens like dust mites, pet dander, and mold spores.
It's a corticosteroid nasal spray that helps to reduce inflammation in the nasal passages, providing relief from symptoms such as sneezing, runny or stuffy nose, and itchy eyes.
How does Nasacort Aq help with these illnesses?
Nasacort Aq is a corticosteroid which acts to reduce inflammation in the body. It works by suppressing the immune system, thereby reducing swelling and inflammation in the nasal passages, offering relief from allergy symptoms such as sneezing, itching or a runny nose. Its action can be likened to that of cortisol, an important hormone produced naturally in our bodies that plays critical roles in many processes including managing stress responses and reducing inflammation. Unlike Zyrtec D which combines an antihistamine with a decongestant for relieving allergic symptoms along with nasal congestion respectively, Nasacort Aq's primary function is targeting and minimizing inflammation specifically within the nasal passages. Therefore, it may be prescribed when patients primarily suffer from persistent nasal allergies or when over-the-counter antihistamines like Zyrtec D are not sufficiently effective.
How effective are both Zyrtec D and Nasacort Aq?
Both Zyrtec D (cetirizine and pseudoephedrine) and Nasacort AQ (triamcinolone acetonide) have been proven effective in treating symptoms related to seasonal allergies, and they were approved by the FDA within a short period of each other. Since they act on different aspects of the allergic response, they may be prescribed under varying circumstances. A double-blind clinical trial conducted in 2003 found that both drugs showed similar efficacy in managing allergy symptoms such as sneezing, runny nose, itchy eyes and throat.
A 2007 study reported that Zyrtec D was effective from the first day of treatment thanks to its combination therapy: antihistamine cetirizine reduces itching while decongestant pseudoephedrine relieves nasal congestion. This dual action makes it particularly useful for patients with severe blocked or stuffy noses due to allergies.
On the other hand, Nasacort AQ is a corticosteroid which works by reducing inflammation caused by allergens. It also helps prevent future reactions when used regularly over a longer period. In fact, according to research findings presented at an American Academy of Allergy Asthma & Immunology meeting in 2016, triamcinolone acetonide can significantly improve all major symptoms associated with hay fever including eye discomfort.
However, unlike Zyrtec D which offers immediate relief upon administration but could cause drowsiness as a side effect due its antihistamine component; Nasacort AQ takes up to one week before significant symptom relief occurs but has an excellent safety profile with minimal systemic absorption resulting into fewer side effects like insomnia or palpitations commonly seen with oral decongestants.

At what dose is Zyrtec D typically prescribed?
Oral dosages of Zyrtec D range from 5-10 mg/day for adults and children over 12 years old, with studies indicating that a daily dose of 5 mg is typically sufficient to alleviate allergy symptoms. Children aged 6 to under 12 years may start at the lower dosage of one tablet (2.5mg) every twelve hours. The maximum dosage that should not be exceeded is two tablets in a twenty-four hour period.
In contrast, Nasacort AQ nasal spray can be used by adults and adolescents over the age of 12 at a dosage rate of two sprays per nostril once daily, totaling 110 mcg per day. Children aged between two and eleven are recommended to use one spray in each nostril daily - equivalent to a total amount of 55 mcg per day. If there's no response after several weeks, you might want to consult your doctor before increasing the usage or changing medications.
At what dose is Nasacort Aq typically prescribed?
Nasacort Aq treatment is generally initiated at a dosage of 2 sprays in each nostril once per day for adults and children aged 12 years and older. Each spray delivers approximately 55 mcg of triamcinolone acetonide. The dose can then be increased to a maximum daily dose of 4 sprays in each nostril (220 mcg/day) if symptoms are not well controlled. After symptom control has been achieved, the dose should be reduced to the lowest amount that effectively maintains relief of symptoms, which may include reverting back to the initial dosage. Children aged between 2-11 years should typically start with one spray in each nostril once daily (110 mcg/day). It's important to note that Nasacort Aq does not provide immediate relief and can take up to one week for full therapeutic effect.

Always consult with your healthcare provider for any concerns regarding medications you are taking.
Contraindications for Zyrtec D and Nasacort Aq?
Both Zyrtec D and Nasacort AQ, along with most other allergy medications, may worsen symptoms in some people. If you notice your allergic reactions intensifying or an increase in side effects such as difficulty breathing, swelling of the face or throat, fainting spells or severe skin rashes after taking these drugs, please seek immediate medical attention.
Neither Zyrtec D nor Nasacort AQ should be taken if you are currently using monoamine oxidase (MAO) inhibitors. Always inform your physician about any medication you are taking; MAOIs will require a period of about 2 weeks to clear from the system to prevent potentially harmful interactions with both Zyrtec D and Nasacort AQ. It's also important to note that prolonged use of nasal corticosteroids like Nasacort can lead to nosebleeds, changes in vision or damage to the septum so regular check-ups with your doctor is advised.
How much do Zyrtec D and Nasacort Aq cost?
For the brand name versions of these drugs:
- The price for 24 tablets of Zyrtec D (Cetirizine/Pseudoephedrine) averages around $20, which works out to about $0.80 per day if you are taking one tablet daily.
- The price for a 16.5g bottle of Nasacort Aq (Triamcinolone acetonide), providing around 120 sprays, is approximately $18; this equates to an average cost of about $0.15 per day based on two sprays in each nostril once daily.
Thus, if you follow the recommended dosage instructions for these medications, Nasacort AQ will be less expensive on a per-day treatment basis than Zyrtec D. However, please note that cost should not be your only consideration when determining which drug is right for you.
As with most medication brands and their generic counterparts:
- Generic cetirizine/pseudoephedrine costs approximately similar or slightly lower compared to branded Zyrtec D.
- Triamcinolone nasal spray can also be purchased as a generic version at comparable prices to Nasacort AQ.
Both are typically cheaper options but deliver equivalent effectiveness; however, individual pricing may vary depending upon location and available discounts or insurance coverage.
Popularity of Zyrtec D and Nasacort Aq
Cetirizine, commonly known by the brand name Zyrtec D, is a popular antihistamine used to treat symptoms of both indoor and outdoor allergies. In 2020, it was estimated that about 3.5 million people in the US were prescribed cetirizine (Zyrtec D). The drug accounted for approximately 14% of all antihistamine prescriptions in the US. Cetirizine has been steadily growing in popularity since its introduction due to its effectiveness at relieving allergy symptoms with lesser sedative effects compared to first-generation antihistamines.
On the other hand, triamcinolone acetonide nasal spray or Nasacort AQ was prescribed to nearly 2 million people in the USA during the same year. It represents roughly around 8% of overall steroid nasal spray prescriptions. Nasacort AQ’s usage has remained relatively stable over recent years despite being an effective treatment option for hay fever and perennial rhinitis because some patients may prefer oral medications like Zyrtec D over a nasal spray application method.
Conclusion
Both Zyrtec-D (cetirizine and pseudoephedrine) and Nasacort AQ (triamcinolone acetonide) are commonly used in the treatment of allergic rhinitis, backed by numerous clinical studies indicating they are more effective than placebo treatments. While both medications can be used to manage symptoms such as sneezing, itching, running nose or congestion, they have different mechanisms of action. Zyrtec-D is an antihistamine combined with a decongestant that works by blocking histamine activity and reducing swelling in the nasal passages respectively; whereas Nasacort AQ is a corticosteroid that reduces inflammation.
In terms of usage scenarios, while Zyrtec-D provides quick relief from allergy symptoms including nasal congestion due to its dual-action formula, it needs to be taken on a regular basis for continued effect. On the other hand, Nasacort AQ may take longer time before full effects are felt but once on-going use begins it can provide 24-hour symptom relief.
Both drugs come in over-the-counter forms which represents significant cost savings especially for patients who must pay out-of-pocket. Side-effects between these two drugs vary: Zyrtec-D has potential side effects like restlessness or insomnia due to pseudoephedrine's stimulant properties whereas Nasacort AQ might lead to nosebleeds or headaches but usually do not cause systemic side effects unless used excessively.
Patients should monitor their body’s reaction when starting treatment with either drug and seek medical help immediately if severe reactions occur.
