Qvar vs Singulair
Introduction
For patients with asthma, certain medications can help manage inflammation and tighten airways. Qvar and Singulair are two such drugs that are often prescribed for this chronic condition. Both work differently to control symptoms of asthma but have the same goal - to enable patients breathe easier. Qvar is a corticosteroid inhaler that works directly in the lungs to reduce swelling and inflammation, thus making it easier for individuals to breathe. On the other hand, Singulair is classified as a leukotriene receptor antagonist which controls and prevents asthma symptoms brought on by allergies by blocking substances in your body called leukotrienes; these substances contribute to inflammation, constriction of airway muscles, and production of mucus—all leading factors contributing towards an asthmatic reaction.
What is Qvar?
Beclomethasone dipropionate, the generic name for Qvar, is an inhaled corticosteroid (ICS) that was a significant step forward from oral corticosteroids in managing chronic respiratory diseases like asthma. Approved by the FDA in 2000, Qvar works by reducing inflammation and swelling within the airways to improve breathing. It is prescribed as a long-term control medication for individuals with persistent asthma.
On the other hand, Montelukast or Singulair blocks leukotrienes substances in your body which cause allergies and asthma symptoms. This drug was introduced after ICSs but has made its mark due to its unique mechanism of action- it does not suppress immune response like steroids do; rather it prevents allergic reactions from triggering bronchoconstriction. One major advantage of Singulair over Qvar is that it can be taken orally once daily making compliance easier especially among pediatric patients.
While both medications are effective at controlling asthma symptoms, they work differently: whereas Qvar directly reduces inflammation inside the lungs (with minimal systemic side effects), Singulair acts more broadly affecting leukotriene pathways throughout the body leading to potential mood changes and sleep disturbances.
What conditions is Qvar approved to treat?
Qvar is approved for the management of various respiratory conditions:
- Asthma as a maintenance treatment
- Chronic obstructive pulmonary disease (COPD) Singulair, on the other hand, is used not only to prevent asthma attacks but also to relieve symptoms of seasonal allergies.
How does Qvar help with these illnesses?
Qvar works to manage asthma by reducing inflammation in the airways of the lungs. It accomplishes this by delivering beclomethasone, a corticosteroid, directly into the bronchial tubes where it suppresses inflammation. This decrease in swelling and irritation can lead to fewer asthma symptoms such as shortness of breath and wheezing. Corticosteroids are hormones naturally produced in our bodies that have anti-inflammatory effects among their many functions.
Asthma is thought to involve an overactive immune response leading to chronic inflammation of the airways. Therefore, by decreasing inflammation with Qvar, we can limit exacerbations or flare-ups characteristic of poorly controlled asthma and help patients manage their condition more effectively.
What is Singulair?
Singulair, known generically as montelukast, is a leukotriene receptor antagonist. It works to control symptoms of asthma and allergic rhinitis by blocking substances in the body called leukotrienes that cause inflammation and constriction of airways in the lungs. Montelukast was first approved by the FDA in 1998. Its mechanism of action differs from inhaled corticosteroids like Qvar (beclomethasone), which work directly on inflammation within the lung tissues. This difference leads to variations in side effects; Singulair does not typically cause oral thrush or hoarseness - common side effects with Qvar use due to its delivery method as an inhaler. Furthermore, Singulair's effect on leukotrienes makes it particularly beneficial for patients whose symptoms are triggered more by allergies rather than physical activity or respiratory infections — conditions where typical inhaler medications like Qvar might fall short.
What conditions is Singulair approved to treat?
Singulair is a potent medication approved for the management and prevention of:
- Asthma, including exercise-induced asthma
- Seasonal allergic rhinitis (hay fever)
- Perennial allergic rhinitis (year-round allergies)
It works by blocking the action of leukotrienes, substances in the body that cause inflammation and constriction in the lungs and development of symptoms associated with allergies.
How does Singulair help with these illnesses?
Leukotrienes are inflammatory chemicals your body releases when you breathe in an allergen such as pollen. These chemicals cause swelling in your lungs and tightening of the muscles around your airways, resulting in asthma symptoms. Singulair (montelukast) works by blocking leukotrienes' action, thereby preventing or relieving chronic asthma's symptoms. Unlike Qvar, which is a steroid inhaler that reduces inflammation directly in the lungs, Singulair comes as a tablet and can also help control allergic rhinitis symptoms like sneezing and runny nose - it's not only effective against bronchial constriction but also has broader anti-allergic properties. This dual-action effect makes Singulair a preferred choice for some patients suffering from both asthma and allergies.
How effective are both Qvar and Singulair?
Both beclomethasone (Qvar) and montelukast (Singulair) are trusted treatments for asthma and were approved by the FDA only a few years apart. They function differently, hence they may be prescribed under varying conditions. The effectiveness of Qvar and Singulair in alleviating asthma symptoms was directly studied in several clinical trials; both drugs showed similar efficacy in managing symptoms as well as similar safety profiles. In these studies, no significant differences were observed between patients receiving Qvar or Singulair.
A review of meta-analysis reports on Qvar demonstrated that it is effective from the first week of treatment, its side effect profile is favorable over many other corticosteroids, and it is well-tolerated even in pediatric populations. This same study reported that Qvar has become one of the most widely-prescribed inhaler medications globally due to its lower required doses compared to other corticosteroids.
On the other hand, a 2016 review indicated that Singulair seems more effective than placebo at treating asthma symptoms and appears comparable to many common bronchodilators. Nonetheless, Singulair is generally considered after (or as an addition to) first-line treatments like short-acting beta agonists or corticosteroids due to some concerns about mental health side effects associated with its use. Much research has involved using Singulair alongside an inhaler so data confirming its efficacy as a standalone treatment isn't as robust as for Qvar. However, because of unique benefits such aiding exercise-induced bronchoconstriction prevention , singulair might be optimal for asthmatic patients who engage frequently in physical activities which exacerbate their condition.
At what dose is Qvar typically prescribed?
Dosages of Qvar are administered through inhalation and range from 40–320 mcg/day, divided into two doses. However, studies suggest that 80 mcg/day is often enough for managing asthma in many individuals. Children may start on a lower dose of around 40 mcg/day. In both cases, the dosage can be increased after several weeks if there is no improvement in symptoms. Nevertheless, it's important to note that the maximum recommended daily dosage should not exceed 320 mcg for adults and adolescents aged over 12 years old or more than 160 mcg for children aged between 5-11 years old.

At what dose is Singulair typically prescribed?
Singulair treatment typically begins with a dosage of 10 mg/day for adults and adolescents aged 15 years or older. For pediatric patients aged 6 to 14 years, the dose is reduced to 5 mg/day, while children aged from 2-5 years should receive a further reduction in dose to just about 4 mg/day. These doses are usually taken once daily in the evening. The maximum permissible dose generally does not exceed these recommended intake levels per day according to age groups, as it is unnecessary. If there seems to be no positive response after a suitable time period of consistent Singulair use, your healthcare provider may reassess your treatment plan.
What are the most common side effects for Qvar?
Common side effects of Qvar may include:
- Throat irritation or pain
- Changes in voice, including hoarseness
- Cough
- Difficulty swallowing
- Dry mouth
- Headache
- Muscle pain or weakness
- Nervousness
While Singulair might cause:
- Abdominal or stomach pain
- Flu-like symptoms (fever, muscle aches)
- General feeling of discomfort or illness
-Trouble sleeping (insomnia)
-Nausea and vomiting
-Coughing, congestion, sinusitis
-Behavioral changes such as agitation, aggression.
It's important to consult with your healthcare provider for any persistent and uncomfortable side effects.
Are there any potential serious side effects for Qvar?
While comparing Qvar to Singulair, it's important to take note of the potential side effects each medication might have. In rare cases, patients taking Qvar may experience:
- Signs of allergic reaction like hives, difficulty breathing, or swelling in your face or throat
- Vision disturbances such as blurred vision or seeing halos around lights
- Fast or irregular heartbeats which could cause fluttering in your chest and shortness of breath; you may also feel dizzy all of a sudden and as if you're about to faint.
On the other hand, Singulair has its own set of potential side effects including:
- Increased thoughts about suicide or self-harm
- Severe skin reactions characterized by fever, sore throat, burning eyes, skin pain and red or purple skin rash accompanied by blistering and peeling
- Disorientation due to low sodium levels leading to symptoms such as headache confusion slurred speech severe weakness vomiting loss of coordination feeling unsteady.
In both instances remember that these are rare but serious conditions. If you happen to experience any such symptom from either medication immediately contact your healthcare professional for advice.
What are the most common side effects for Singulair?
Common side effects of Singulair may include:
- Upper respiratory infection
- Fever
- Headache
- Sore throat, cough, nasal congestion
- Stomach pain, diarrhea, dyspepsia or indigestion
- Rash or bruising under the skin (purpura)
- Flu-like symptoms such as muscle aches and fatigue
- Dental pain While these side effects are generally mild and manageable, it's important to note that in rare cases there have been reports of severe mood changes and hallucinations associated with Singulair usage. Always consult your healthcare provider if you're concerned about potential side effects.
Are there any potential serious side effects for Singulair?
Like any other medication, Singulair can potentially cause side effects. It's crucial to be aware of these and monitor your health while taking this medication. Here are some serious side effects you should look out for:
- Signs of an allergic reaction such as a rash or hives, itching, difficulty breathing or swallowing, swelling in your face or throat
- Mood changes including agitation, aggression, depression or suicidal thoughts
- A feeling like you might pass out
- Severe tingling or numbness
- Painful sinusitis symptoms like severe pain behind your eyes
- Uncontrolled muscle movements
- Irregular heartbeat
If you observe any of these signs after starting on Singulair, please discontinue the drug immediately and seek medical attention promptly.
Contraindications for Qvar and Singulair?
Both Qvar and Singulair, similar to other medications for asthma control, may cause an increase in asthma symptoms or lead to a severe asthmatic attack in some people. If you notice your asthma worsening or experience difficulty breathing, please seek immediate medical attention.
Neither Qvar nor Singulair should be taken if you are using certain types of medications like steroid tablets/medicine without consulting your doctor first. Always tell your physician which medications you are taking; steroids will require a gradual decrease before they can be completely stopped to prevent withdrawal symptoms and potential adverse reactions with Qvar and Singulair.
It is also important to note that these medicines cannot provide immediate relief from sudden/severe asthma attacks. In such cases, the use of quick-relief inhalers (bronchodilators) is necessary. Make sure not to stop using any prescribed medication suddenly without discussing it with your healthcare professional.
How much do Qvar and Singulair cost?
For the brand name versions of these drugs:
- The price of a 120-dose inhaler of Qvar (40 mcg) averages around $200, which works out to approximately $1.67/day.
- The price of 30 tablets of Singulair (10 mg) is about $170, working out to roughly $5.66/day.
Thus, if you are using one dose per day for your asthma or COPD treatment with Qvar, it turns out cheaper than Singulair on a daily basis. It's important to remember that cost should not be the deciding factor when choosing between these drugs; effectiveness and compatibility with your condition should be primary considerations.
In terms of generic options:
- Beclomethasone dipropionate (the active ingredient in Qvar), currently does not have a direct generic version available in the US market.
- Montelukast sodium (generic for Singulair) costs significantly less at about $0.50 per tablet or around $15/month depending on insurance coverage and pharmacy pricing policies.
Please note: Always consult with your healthcare provider before making any decisions regarding medication usage.
Popularity of Qvar and Singulair
Beclomethasone dipropionate, available under the brand name Qvar among others, is a corticosteroid medication that is used to prevent and control symptoms caused by asthma. In 2020, it was estimated to have been prescribed to about 4 million people in the US. Beclomethasone accounted for just over 20% of inhaled corticosteroid prescriptions in the US and has been generally increasing in prevalence since 2013.
On the other hand, Montelukast (brand name Singulair) was prescribed to around 6 million people in the USA during the same year. This medication accounts for almost half of leukotriene receptor antagonist prescriptions and approximately one-fifth of overall asthma treatment prescriptions. The use of montelukast has remained steady over time despite concerns regarding its side effects on mental health.
Conclusion
Both Qvar (beclomethasone) and Singulair (montelukast) are widely used in the management of asthma, with numerous clinical studies supporting their effectiveness in comparison to placebo treatments. Both medicines can be combined if deemed necessary by a physician, but it should be done under careful consideration as they work differently. Qvar is an inhaled corticosteroid that works by reducing inflammation within the lungs, while Singulair is a leukotriene receptor antagonist that prevents airway edema and bronchoconstriction.
Qvar is often considered as a first-line treatment for persistent asthma control due to its direct anti-inflammatory action on the lungs. On the other hand, Singulair would usually be contemplated as add-on therapy for those who did not respond well to first-line inhaler treatments or have exercise-induced bronchoconstriction or allergies along with asthma.
Both medications are available in generic form which brings significant cost savings especially for patients paying out-of-pocket. The effects of both Qvar and Singulair might not be noticeable immediately since these are preventive medications meant to control long-term symptoms rather than provide immediate relief from acute attacks.
The side-effect profiles between these two drugs differ somewhat; common side-effects with Qvar include oral thrush and hoarseness while those associated with Singulair include headache and stomach upset. For both drugs, patients must monitor their breathing closely when starting treatment and should seek medical help immediately if they notice their symptoms worsening or experience allergic reactions.
