Side Effects





For patients suffering from allergies, certain medications can help manage symptoms such as sneezing, runny nose, itchy eyes and throat. Nasacort AQ and Allegra are two such drugs that are often prescribed for allergy relief. They each impact different aspects of the allergic response but both provide symptomatic relief to patients with allergies. Nasacort AQ is a corticosteroid nasal spray that works by reducing inflammation in the nasal passages, while Allegra is an antihistamine which functions by blocking histamines - substances in the body that cause allergic symptoms.

What is Nasacort Aq?

Triamcinolone acetonide (the generic name for Nasacort AQ) was a significant advancement in the class of intranasal corticosteroids used for treating seasonal and perennial allergic rhinitis. First approved by the FDA in 1996, Nasacort AQ reduces inflammation by inhibiting multiple types of cells and chemicals responsible for allergic reactions. It is applied directly to the nasal passages to provide relief from symptoms such as sneezing, itching, and runny nose. Unlike antihistamines like Fexofenadine (Allegra), which block histamine release to prevent allergy symptoms, Nasacort AQ has a broader range of action that tackles more causes of irritation. This results in it having a more comprehensive effect on allergies with only minor systemic absorption leading to fewer side effects compared to oral medications that have stronger effects throughout your body.

What conditions is Nasacort Aq approved to treat?

Nasacort AQ is approved for the treatment of various symptoms associated with:

  • Seasonal and perennial allergic rhinitis, commonly known as hay fever
  • Allergic reactions that cause inflammation in the nasal passages (in adults and children aged 2 years and older)
  • Congestion, sneezing, runny nose, and itchy or watery eyes caused by allergies

How does Nasacort Aq help with these illnesses?

Nasacort AQ works to manage allergy symptoms by minimizing the inflammatory response in the nasal passages. It achieves this by mimicking corticosteroids, hormones that regulate inflammation within our bodies, leading to decreased swelling and lessened mucus production. This action not only reduces immediate allergy symptoms like sneezing and itching but also provides long-lasting relief from congestion. Nasal corticosteroids such as Nasacort AQ are particularly effective at addressing nasal allergies because they directly target the site of inflammation.

On the other hand, Allegra (generic name fexofenadine) operates somewhat differently – it is an antihistamine medication designed to block histamine, a chemical released during allergic reactions which causes symptoms like runny nose or watery eyes. By blocking histamine's effect on its receptors in cells throughout the body, Allegra curbs these acute responses without causing drowsiness common with some older antihistamines.

What is Allegra?

Allegra, the brand name for fexofenadine, is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes and runny nose. Fexofenadine is used to treat these symptoms caused by seasonal allergies in adults and children. It is also used to treat skin itching and hives caused by a condition called chronic idiopathic urticaria.

Fexofenadine was first approved by the FDA in 2000. Unlike some other antihistamines like diphenhydramine (Benadryl), fexofenadine does not cross into the brain from the blood and therefore causes less drowsiness. This means that its side-effect profile is different from those of older or "typical" antihistamines which often cause sedation as well as dry mouth and vision problems.

The non-drowsy effect on histamine response can be very beneficial for people who need allergy relief but don't want to feel sleepy or sluggish during their day-to-day activities — this makes Allegra particularly suitable for daytime use.

What conditions is Allegra approved to treat?

Allegra, known generically as fexofenadine, is approved for the treatment of:

  • Seasonal allergic rhinitis (hay fever)
  • Chronic idiopathic urticaria (hives with no known cause)

It's an effective antihistamine that provides 24-hour relief from persistent allergy symptoms.

How does Allegra help with these illnesses?

Fexofenadine, the active ingredient in Allegra, is a second-generation antihistamine that works by blocking the action of histamine, a substance involved in allergic reactions. While both Nasacort AQ and Allegra are effective for allergy symptoms such as runny nose, itchy or watery eyes and sneezing, their mechanisms of action differ significantly. Unlike Nasacort AQ which is a corticosteroid nasal spray used to decrease inflammation in the nasal passages, Allegra does not have significant anti-inflammatory effects but targets histamine's actions directly helping to alleviate allergy symptoms without causing drowsiness. It also has less interaction with other medicines compared to some older antihistamines thus making it more preferable when patients are on multiple medications.

How effective are both Nasacort Aq and Allegra?

Both triamcinolone acetonide (Nasacort AQ) and fexofenadine (Allegra) have established histories of success in treating patients with allergies, and they were initially approved by the FDA within a few years of each other. Since they act on different pathways associated with allergic reactions, they may be prescribed under different circumstances. The effectiveness of Nasacort AQ and Allegra in alleviating allergy symptoms was directly studied in several clinical trials; both drugs exhibited similar efficacy in managing symptoms such as sneezing, runny nose, itchy or watery eyes, hives, skin rash as well as promising safety profiles.

A 2003 review demonstrated that Nasacort AQ is effective at relieving nasal allergy symptoms starting from the first day of treatment due to its anti-inflammatory effects; its side effect profile showed minimal systemic absorption compared to many other corticosteroids making it safe for long-term use even among children above two years old. It has become one of the most widely used intranasal corticosteroids worldwide.

On the other hand, a 2012 meta-analysis indicated that Allegra seems to be more effective than placebo in controlling seasonal allergic rhinitis symptoms without causing drowsiness - a common side effect linked to many antihistamines. However significant research on its use involves being co-prescribed alongside an intranasal corticosteroid like Nasacort AQ for best results especially during peak allergy seasons; data confirming its efficacy alone is less robust than that for Nasacort AQ which can address broader range of allergic inflammation including persistent year-round allergies not just those triggered seasonally.

Popularity of Nasacort Aq and Allegra

Triamcinolone acetonide, commonly known by the brand name Nasacort AQ, is a nasal spray used for allergy relief. In 2020, it was estimated that about 1.9 million prescriptions were filled in the US. Triamcinolone accounts for approximately 15% of intranasal steroid prescriptions and offers a non-drowsy solution to manage perennial allergic rhinitis symptoms.

On the other hand, fexofenadine (brand version Allegra) saw an estimate of 4.2 million prescribed users in the USA during the same year. Fexofenadine constitutes around 16% of all second-generation antihistamine prescriptions which are known for lesser sedative effects compared to first-generation ones. The overall usage has seen little fluctuation over recent years due to its effectiveness against seasonal allergies and hives without causing drowsiness.


Both Nasacort AQ (triamcinolone acetonide) and Allegra (fexofenadine) are popular options for dealing with allergies, supported by a plethora of clinical data showing their efficacy over placebo. While they can be used together in some instances, this should always be under the careful guidance of a healthcare professional due to potential drug interactions. Their dissimilar modes of operation mean they’re often chosen for different situations; Nasacort AQ acts as a corticosteroid reducing inflammation within the nose while Allegra works systemically as an antihistamine blocking histamine's effects.

Nasacort AQ is typically utilized when nasal symptoms like congestion or rhinitis are dominant, whereas Allegra would normally be selected when broader allergy symptoms such as itching and watery eyes need addressing. Both medications come in generic forms offering cost savings - particularly beneficial for those bearing costs personally.

An adjustment period may apply to both medications meaning immediate relief might not occur. The side effect profiles between these two drugs bear similarity – generally well-tolerated but with Nasacort potentially causing more localized nasal irritation compared to Allegra which has minimal sedative effects unlike other antihistamines. It’s important that patients keep track of their symptom control upon starting treatment and contact their doctor promptly if conditions worsen or new issues arise.
