Qnasl vs Qvar
Introduction
For individuals dealing with respiratory conditions such as asthma or allergic rhinitis, certain medications that assist in reducing inflammation and managing symptoms can be immensely helpful. Qnasl and Qvar are two such drugs often prescribed for these conditions. Although they both have a role in treating respiratory disorders, their mechanisms of action differ slightly which affects their specific uses.
Qnasl is a corticosteroid nasal spray primarily used to alleviate symptoms associated with seasonal and year-round allergies. It works by controlling the rate of protein synthesis, depressing the migration of polymorphonuclear leukocytes and fibroblasts, reversing capillary permeability, and stabilising lysosomal membranes at the cellular level to prevent or control inflammation.
On the other hand, Qvar is an inhaled corticosteroid designed mainly for regular long-term management of asthma symptoms. It acts directly on bronchial smooth muscle to decrease inflammatory response within the lungs thereby reducing frequency and severity of asthma attacks.
What is Qnasl?
Beclomethasone, also known under the brand name Qnasl, was one of the first corticosteroid nasal sprays introduced to treat allergies. This marked a significant development from oral allergy medications that could have systemic side effects. The U.S. Food and Drug Administration (FDA) approved beclomethasone in 1976 for prescription use. It works by reducing inflammation in the nose, thus alleviating symptoms such as sneezing and stuffy or runny nose.
On the other hand, Qvar is another formulation of Beclomethasone designed to manage asthma symptoms by decreasing inflammation in the lungs, preventing breathing difficulties, wheezing and coughing caused by this chronic disease. Unlike Qnasl that primarily affects nasal passages, Qvar has a direct influence on lung tissue with only minor influence elsewhere which results in it having fewer systemic side effects than other steroids taken orally or through injection.
What conditions is Qnasl approved to treat?
Qnasl and Qvar are both approved for the management of different respiratory conditions:
- Qnasl is used to treat nasal symptoms such as congestion, sneezing, and runny nose caused by seasonal or year-round allergies.
- Qvar is a maintenance treatment for asthma as prophylactic therapy in patients 5 years of age and older. It's not recommended for relief during an acute asthma attack.
How does Qnasl help with these illnesses?
Qnasl aids in managing allergic rhinitis symptoms by reducing nasal inflammation. It achieves this by utilizing the anti-inflammatory properties of its active ingredient, Beclomethasone dipropionate, a corticosteroid. Qnasl works directly on the nasal passageways when administered through intranasal delivery, thereby minimizing systemic exposure and side effects.
On the other hand, Qvar is designed to manage asthma symptoms. Like Qnasl, it also contains a corticosteroid as its active ingredient - Beclomethasone dipropionate – which reduces inflammation within the bronchial tubes of the lungs when inhaled. By decreasing such inflammation in these airways, patients can experience relief from common asthma symptoms such as shortness of breath and wheezing.
Though both medications contain similar ingredients and have anti-inflammatory properties aimed at different parts of respiratory system - one targets your nose (Qnasl), while another targets your lungs (Qvar). Both are integral for effective symptom management but their usage depends upon whether you're dealing with allergies or asthma respectively.
What is Qvar?
Qvar, also known as beclomethasone dipropionate, is primarily used for the long-term management of asthma. Like Qnasl, it belongs to a class of medications called corticosteroids which work by reducing inflammation in the airways. When compared to Qnasl (a nasal spray), Qvar is an inhaler and directly targets the lungs rather than just the nasal passages. The delivery method allows it to effectively manage ongoing symptoms of asthma such as wheezing and shortness of breath.
Qvar was approved by the FDA in 2000 and has been widely prescribed since then due its efficacy in controlling asthma when used over time. Unlike some other respiratory drugs, it does not cause sedation or other central nervous system side effects because its action is mostly localised within lung tissues.
The side-effect profile of Qvar differs from that of many oral corticosteroid medications; common side effects may include hoarseness or throat irritation but systemic side effects are less likely due to low absorption into blood circulation. Therefore, patients who do not respond well or have contraindications for oral steroids might find better treatment outcomes with a drug like Qvar.
What conditions is Qvar approved to treat?
Qvar is a corticosteroid inhaler that's approved for the management and prevention of asthma symptoms in patients aged five and older. Some conditions it is used to treat include:
- Chronic asthma
- Exercise-induced bronchospasm (EIB)
It works by reducing inflammation in the airways, making breathing easier.
How does Qvar help with these illnesses?
Corticosteroids are a type of medication that reduces inflammation in the body, making it an effective treatment for conditions such as asthma and allergies. Qvar, a corticosteroid inhaler, works by reducing swelling and irritation in the airways to improve breathing. It performs its action directly in the lungs which is beneficial as it results in fewer side effects compared to systemic corticosteroids. Unlike Qnasl, which is primarily used for allergic rhinitis symptoms like sneezing or runny nose due to its antihistamine properties, Qvar focuses on long-term control and prevention of asthma symptoms. Its localized action may also play roles in reducing potential systemic side effects associated with oral steroids. Consequently, it might be prescribed when patients do not respond well to “typical” short-acting bronchodilators or may be combined with other controllers (like long-acting beta agonists) for better control over severe cases of asthma.
How effective are both Qnasl and Qvar?
Both beclomethasone (Qnasl) and beclomethasone dipropionate (Qvar) are corticosteroid drugs that have established histories of success in treating patients with allergic rhinitis and asthma, respectively. They were initially approved by the FDA within a few years apart. Since they act on different respiratory conditions, they may be prescribed under different circumstances.
The effectiveness of Qnasl and Qvar was directly studied in several clinical trials; the two drugs exhibited similar efficacy in managing symptoms of allergies or asthma as well as promising safety profiles. In most studies, none of the metrics used to measure efficacy differed significantly between patients receiving Qnasl for seasonal or perennial allergic rhinitis and those receiving Qvar for control of asthma symptoms.
A review demonstrated that both drugs offer significant symptom relief starting from the first week of treatment, their side effect profile is favorable over many other corticosteroids, and they are well-tolerated even in children and elderly populations. The usual dose showing optimal efficacy varies depending upon the severity of symptoms but usually ranges from one to four inhalations per day.
While both medications seem more effective than placebo at controlling respective allergy or asthma symptoms, there's still ongoing research regarding their comparative efficacies against other steroid treatments. Nonetheless due to its unique delivery system and low systemic bioavailability which reduces potential side effects like oral thrush or hoarseness associated with inhalational steroids use , these can be an optimal treatment choice for those who require long term control medicine .
At what dose is Qnasl typically prescribed?
Inhaled dosages of Qnasl for adults and adolescents aged 12 years and older range from 1-2 sprays in each nostril once daily, but studies have shown that one spray per nostril daily is usually adequate for controlling symptoms of seasonal and perennial allergic rhinitis. Children aged 4 to 11 years may be started on a dose of one spray in each nostril once daily. For either population, the dosage can be increased after a few weeks if there are insufficient symptom control. The maximum dosage that should not be exceeded is two sprays in each nostril per day.
On the other hand, Qvar RediHaler is used for the maintenance treatment of asthma as prophylactic therapy in patients aged four years or older. In adults and adolescents who are at least twelve years old, recommended doses vary widely ranging from 40 mcg to a maximum dose of 640 mcg per day divided into two doses. Pediatric patients aged between four to eleven years should start at lower doses with subsequent adjustments according to their response but not exceeding more than twice spacing out throughout the day.

At what dose is Qvar typically prescribed?
Qvar treatment typically begins with one to two inhalations at a dosage of 40-80 mcg/day for adults and children older than 5 years. Dosage can then be increased to a maximum daily dose of 320 mcg, divided into two doses, spaced about 12 hours apart. It may take as long as three weeks before the full benefits of Qvar are felt due to its design for long-term control rather than immediate relief. If there is no response or if symptoms worsen after this period, your healthcare provider may decide to adjust the dosage or consider other treatment options.

- Unusual tiredness, nervousness, or tremors.
In some rare instances, Qvar may cause significant weight loss. Like any medication, it's essential to discuss potential side effects with your healthcare provider before starting treatment.
Are there any potential serious side effects for Qvar?
While Qvar is generally safe and effective in managing asthma symptoms, some individuals may experience severe side effects. If you notice any of these following symptoms while using Qvar, seek immediate medical attention:
- Signs of an allergic reaction such as hives; difficulty breathing; swelling of your face, lips, tongue, or throat
- Worsening asthma symptoms or shortness of breath
- Chest pain and fast/irregular heartbeats
- White patches in the mouth or on the tongue (a sign of a fungal infection known as thrush)
- Blurred vision or other changes in sight
- Unusual mood swing or behavior changes
- Severe fatigue and lack of energy which could be signs of adrenal insufficiency.
Remember that it's always important to discuss potential side effects with your healthcare provider before starting new medications.
Contraindications for Qnasl and Qvar?
Both Qnasl and Qvar, like most asthma medications, may cause symptoms to worsen in some individuals. If you notice your asthma or allergies worsening, or an increase in wheezing, shortness of breath or other breathing difficulties after using these inhalers, please seek immediate medical attention.
Neither Qnasl nor Qvar should be taken if you are currently taking certain types of antifungal or anti-HIV medicines due to potential harmful interactions. Always inform your healthcare provider about all the medications you are taking; such drugs may require a period of time to clear from the system before starting treatment with either Qnasl or Qvar.
Additionally, it's important not to suddenly stop using these inhalers without consulting your doctor as this can lead to withdrawal symptoms. For patients transferring from steroid therapy to inhaler use, careful monitoring is necessary during transition as adrenal insufficiency could occur.
How much do Qnasl and Qvar cost?
For the brand name versions of these drugs:
- The price of 120 doses of Qnasl (80 mcg nasal spray) averages around $220, which works out to roughly $1.83/day.
- The price for 100 doses of Qvar Redihaler (40 mcg inhalation aerosol) is about $200, equating to approximately $2/day.
Thus, if you are in the regular dosage range for both medications (i.e., one dose per day), then brand-name Qnasl appears to be slightly less expensive on a daily basis. However, please note that cost should not be your primary consideration when deciding which drug is right for you.
As with many other medications, there currently aren't generic alternatives available for either Qnasl or Qvar. This means that patients will have to rely on insurance coverage or discount programs to help reduce costs where possible.
Popularity of Qnasl and Qvar
Beclomethasone dipropionate, marketed under the brand name Qnasl among others, is a steroid medication that is inhaled to manage symptoms of allergic rhinitis. In 2019, approximately 1 million prescriptions were written for this medication in the United States.
On the other hand, Beclomethasone dipropionate also comes as an inhaler under the brand name Qvar. It's used primarily for long-term management of asthma symptoms. This version was prescribed to about 3 million people in the USA during 2020.
Even though both medications contain beclomethasone dipropionate and are administered via inhalation, they serve different purposes with one aimed at alleviating allergy symptoms and the other dedicated towards controlling asthma symptoms. Over time, their usage has remained relatively steady despite new treatment options becoming available.
Conclusion
Both Qnasl (beclomethasone nasal) and Qvar (beclomethasone oral inhalation) are types of corticosteroid medications which help to reduce inflammation. They have a long-standing record of usage in the management of allergies and asthma, with numerous clinical studies supporting their efficacy over placebo treatments. Both drugs work by reducing inflammation in the airways but are administered differently: Qnasl is used nasally for allergic rhinitis symptoms such as sneezing, itching, and runny or stuffy nose; while Qvar is an inhaled medication intended for long-term control of asthma symptoms.
While both drugs contain beclomethasone as an active ingredient, they should not be used interchangeably due to their differing mechanisms and routes of administration. The decision on whether to use one over the other should come down to the patient's specific needs - if nasal allergy symptoms are more problematic, Qnasal may be chosen, whereas if control of chronic asthma is needed then Qvar would typically be prescribed.
Side effect profiles between these two drugs vary based on administration route - common side effects for each include headaches and unpleasant taste or smell for Qnasl users, versus throat irritation or cough for those using Qvar. As with any medication regimen involving corticosteroids like these two products do require close monitoring by a healthcare professional due to potential systemic side effects.
