Montelukast Cost Without Insurance: Generic and Singulair Prices 

The montelukast cost without insurance can be very low or surprisingly high, depending on what you buy and where you fill it. As of October 21, 2026, a 30-day supply of generic montelukast 10 mg tablets is listed from about $5.81 to $11.50 at discounted cash prices, while brand-name Singulair 10 mg is listed at about $290 for the same 30 tablets. Using a free prescription discount card and comparing pharmacies is usually the fastest way to land near the low end of that range.

Montelukast is a prescription medication sold as a generic and under the brand name Singulair. Your actual price depends on the strength, the form (tablet, chewable tablet, or oral granules), the quantity, the pharmacy, and whether a discount is applied. This guide breaks down each of those factors with verified, date-stamped prices, then covers practical ways to pay less and the safety information every patient should know before starting this drug.

How Much Does Montelukast Cost Without Insurance?

For most adults, the question really means: what does a month of generic montelukast 10 mg cost? With a discount card or coupon price, 30 tablets are listed from about $5.81, and 90 tablets from about $8.25, according to the Drugs.com price guide checked on October 21, 2026. Those are cash prices for people paying without insurance, and they reflect discounted pricing rather than the pharmacy’s full list price.

Without any discount, the numbers climb fast. SingleCare lists an average retail price of about $388.91 for 90 tablets of montelukast 10 mg, and GoodRx has reported an average retail price of about $65.34 for 30 tablets. The gap between the full retail price and a discounted cash price is the main reason two people can pay very different amounts for the exact same bottle.

Brand-name Singulair sits in a different price tier entirely. The Drugs.com price guide lists Singulair 10 mg at about $290.57 for 30 tablets and about $855.92 for 90 tablets. Unless your prescriber has a specific medical reason to require the brand, the generic is the far more affordable choice.

Montelukast Generic vs. Brand-Name Singulair Prices

Generic montelukast contains the same active ingredient as Singulair and is approved by the FDA as a therapeutic equivalent. The price difference comes from market competition, not from a difference in the medicine itself. Many manufacturers make generic montelukast, which keeps prices low, while Singulair is made by one company and priced as a brand product. Our guide to generic vs brand-name drugs explains why that gap exists for so many medications.

Here is how the two compare across common strengths, using discounted cash prices from the Drugs.com price guide checked on October 21, 2026.

One more detail matters at the counter. If your prescription is written as “dispense as written,” the pharmacy may not be allowed to substitute the generic. Our explainer on what DAW means covers how that code affects your cash price, and it is worth checking your prescription before you pay brand pricing by accident.

Montelukast Cost by Dosage and Formulation

Montelukast comes in more than one form because it is prescribed to adults, teens, and young children. The right form is chosen by your prescriber based on age and the condition being treated, so the notes below are about price, not about which one you should use. Each strength is priced separately, and the cheapest form is not always the one you would expect.

10 mg Tablets

The 10 mg film-coated tablet is the usual adult and teen strength, and it is also the least expensive form per dose. Discounted cash prices start near $5.81 for 30 tablets, which works out to roughly 19 cents per tablet. Because so many people take this strength, nearly every pharmacy keeps it in stock, which helps keep prices competitive.

5 mg Chewable Tablets

The 5 mg chewable tablet is typically prescribed for children in a younger age range set by the prescribing information. It is listed from about $13.29 for 30 chewable tablets at discounted cash prices. That is more than twice the cost of the adult tablet, even though the dose is smaller, because fewer people use this form.

4 mg Chewable Tablets

The 4 mg chewable is designed for younger children. It is listed from about $13.49 for 30 tablets and about $24.88 for 90 tablets. Chewables contain aspartame, which matters for people with phenylketonuria (PKU), so tell your pharmacist if that applies to your child.

4 mg Oral Granules

Oral granules are the most expensive generic form, listed from about $45.51 for 30 packets. They are used for very young children who cannot chew a tablet, and each packet is opened right before a dose. If your child’s prescriber thinks a chewable could work instead, it is reasonable to ask, since the cost difference can add up over a full allergy or asthma season.

Montelukast 30-Day vs. 90-Day Supply Cost

Montelukast is usually taken once a day for a long period, which makes it a strong candidate for a 90-day fill. The listed discounted cash price for 90 tablets of the 10 mg strength starts near $8.25, only a few dollars more than many 30-day prices. In other words, a 90-day fill can bring the per-tablet cost down to around 9 cents.

Here is how that plays out over a year for one adult on 10 mg daily, using the low end of the listed prices:

• Twelve 30-day fills of generic: about 12 x $5.81 = $69.72 per year
• Four 90-day fills of generic: about 4 x $8.25 = $33.00 per year
• Four 90-day fills of brand-name Singulair: about 4 x $855.92 = $3,423.68 per year

A longer supply is not always the right move. If you are just starting montelukast, many prescribers prefer a short trial first so you can watch for side effects. Our article on the 90-day supply question walks through when the larger fill saves money and when it does not.

Why Does Montelukast Cost Vary Between Pharmacies?

It surprises many people that the same generic tablet can cost $6 at one pharmacy and over $60 at another down the street. Pharmacies set their own retail cash prices, buy from different wholesalers, and negotiate different rates with discount networks. As a result, the price you see depends on which pharmacy you walk into and which discount, if any, you show.

Several factors drive that variation:

• Retail list price: each pharmacy sets its own “usual and customary” cash price, which is often far higher than any discounted rate.
• Discount network contracts: discount programs negotiate rates pharmacy by pharmacy, so the same card can produce different prices at different stores.
• Location: prices can change by city, state, and even by store within the same chain.
• Quantity and strength: pricing tiers change with the number of tablets and the formulation.
• Manufacturer and stock: a pharmacy may carry a generic from a supplier that costs it more, especially during shortages.

If you want the full picture, our breakdown of why drug prices vary explains the system behind these differences in plain language.

How Much Can Prescription Discount Cards Reduce Montelukast Costs?

For montelukast, a discount card is often the single biggest money saver for people without insurance. The difference between a full retail price and a discounted cash price can be dramatic. SingleCare, for example, lists an average retail price of about $388.91 for 90 tablets of montelukast 10 mg, while discounted programs list the same quantity under $20.

The NuLifeSpan Rx card is free, has no enrollment fees, and is accepted at more than 35,000 pharmacies nationwide, including major chains and independent stores. Savings vary by medication and pharmacy and can be up to 80% off retail prices, so your exact montelukast price will depend on where you fill it. If you sign up for a personalized card, eligible prescription purchases also earn $1.50 cashback each, which adds up for a daily medication filled every month.

A few important limits apply. The NuLifeSpan Rx program is not insurance, and discounted purchases do not count toward your insurance deductible or out-of-pocket maximum. If you are curious about the mechanics behind the price on your screen, our guide on how discount cards work explains where the savings come from.

Where Can You Find Lower Montelukast Prices?

The cheapest place to fill montelukast is not the same for everyone, because prices depend on your zip code and the discount you use. That is why a quick price comparison before each fill makes sense. Start with the pharmacies you can easily reach, then compare them against mail-order options.

Good places to check include:

• Large retail chains: CVS, Walgreens, Walmart, Kroger, and similar chains all accept discount cards, but their prices can differ widely.
• Warehouse club pharmacies: Costco and similar stores often post competitive generic prices, so it is worth calling your local store to ask about its cash price and pharmacy access rules.
• Independent pharmacies: local pharmacies sometimes beat chain prices on common generics, so it is worth a phone call.
• Mail-order and online pharmacies: these can be useful for 90-day supplies of maintenance medications.
• Nonprofit programs: Rx Outreach, a nonprofit mail-order pharmacy, lists Singulair (montelukast) among its medications. You can check current pricing at Rx Outreach.

Our step-by-step guide to finding the cheapest pharmacy shows how to compare prices quickly without calling every store in town.

How to Save Money on Montelukast Without Insurance

The biggest savings usually come from combining two or three simple steps rather than relying on one. Most of these take only a few minutes and can be repeated at every refill. Here is a practical checklist to work through before you pay.

1. Ask for the generic. Make sure your prescription allows generic substitution unless your prescriber says the brand is medically necessary.
2. Compare prices before each fill. Prices change, so the cheapest pharmacy this month may not be the cheapest in three months.
3. Show a discount card every time. Ask the pharmacist to run both the card price and the regular cash price, then pay the lower one.
4. Consider a 90-day supply. Once you and your prescriber know the medication works for you, a larger fill often cuts the per-tablet cost.
5. Ask about the most affordable form. For children, ask whether a chewable tablet is appropriate instead of more expensive granules.
6. Check assistance programs if cost is still a barrier. Nonprofit and income-based options exist, and our guide to patient assistance programs explains how they work.

If montelukast is one of several medications you pay for out of pocket, our broader guide on how to afford prescriptions without coverage covers budgeting and timing strategies that apply to your whole medication list.

What Is Montelukast Used For?

Montelukast belongs to a class of medications called leukotriene receptor antagonists. It works by blocking leukotrienes, natural substances in the body that cause airway swelling, tightening, and mucus in asthma, as well as nasal symptoms in allergies. It is taken by mouth once a day and is meant for ongoing control, not quick relief.

According to MedlinePlus, montelukast is used to:

• Prevent wheezing, chest tightness, coughing, and difficulty breathing caused by asthma in adults and children 12 months and older
• Prevent breathing problems during exercise (exercise-induced bronchospasm) in adults and children 6 years and older
• Treat symptoms of seasonal allergic rhinitis in adults and children 2 years and older, and year-round allergic rhinitis in adults and children 6 months and older

For asthma, montelukast is usually taken in the evening. For exercise-related symptoms, it is taken at least 2 hours before exercise, and people already taking a daily dose should not take an extra one. For allergies, it can be taken at any time of day, as long as it is taken around the same time each day.

Important Montelukast Safety Information

Montelukast carries an FDA boxed warning, which is the agency’s most prominent type of safety warning. In March 2020, the FDA required this warning because of reports of serious neuropsychiatric events, including agitation, depression, sleep problems, and suicidal thoughts or actions. The FDA also requires a Medication Guide to be given with every montelukast prescription, so read it each time you pick up a refill.

The FDA Boxed Warning and Allergic Rhinitis

The boxed warning has a specific message for allergy treatment. The FDA advises that, for allergic rhinitis, montelukast should be reserved for patients who have an inadequate response to, or cannot tolerate, alternative therapies. It also advises prescribers to avoid montelukast for patients with mild symptoms. The details are in the FDA Drug Safety Communication, and the full wording appears in the Singulair prescribing information.

The asthma indication was not restricted in the same way. Based on its benefit-risk review, the FDA kept montelukast’s asthma use in place, while still requiring the warning and advising that all patients be told about the risk and monitored for symptoms.

Mental Health and Behavior Changes to Watch For

MedlinePlus notes that these changes can happen during treatment or after the medication is stopped, and they can occur in people with no history of mental health problems. Call the prescriber right away and stop taking montelukast if you notice symptoms such as:

• Agitation, aggression, anxiety, or irritability
• Depression, or suicidal thoughts or actions
• Trouble sleeping, unusual or vivid dreams, or sleepwalking
• Confusion, memory problems, or trouble paying attention
• Hallucinations, restlessness, or tremor

Parents and caregivers should know these warning signs too, especially when a child is taking montelukast. If anyone has thoughts of self-harm, call or text 988 to reach the Suicide and Crisis Lifeline, or call 911 in an emergency.

Montelukast Is Not a Rescue Medication

Montelukast does not treat a sudden asthma attack. People with asthma need a separate short-acting rescue inhaler prescribed by their healthcare provider for acute symptoms. Montelukast also should not be swapped in for inhaled or oral corticosteroids without the prescriber’s guidance. If you also pay cash for a controller inhaler, our guide to fluticasone inhaler costs covers another common part of an asthma treatment plan.

Common, less serious side effects listed by MedlinePlus include headache, heartburn, stomach pain, tiredness, and diarrhea. Tell your prescriber and pharmacist about all other medications you take, including gemfibrozil, phenobarbital, and rifampin, and let them know if you have liver disease, are pregnant, or are breastfeeding.

Montelukast vs. Other Allergy Medications: Cost and Treatment Differences

Because of the boxed warning, montelukast is generally not the first choice for seasonal allergies alone. Other options, such as nasal corticosteroid sprays and newer oral antihistamines, are widely used and many are available over the counter. These medications work differently from montelukast, so they are not automatically interchangeable, and any switch should be discussed with your prescriber.

The comparison below uses discounted cash or pharmacy listing prices from the Drugs.com price guide, checked October 21, 2026. Package sizes differ, so compare price per dose rather than box price alone.

Price is only one part of the decision. A nasal steroid spray, for example, treats nasal inflammation directly and may take several days of regular use to reach full effect, while montelukast is a pill that also helps some people with asthma. Your prescriber can weigh your symptoms, other conditions, and safety concerns to decide what fits best.

Does Insurance Usually Cover Montelukast?

Yes, in most cases. Generic montelukast is a common, low-cost medication, and GoodRx reports that most health insurance plans cover it without prior authorization or step therapy. Brand-name Singulair is a different story, and some plans may require prior authorization or a higher copay tier before they cover it.

Even with insurance, a discount card price can sometimes be lower than your copay, especially if you have not met your deductible. People on a high-deductible plan often pay the full negotiated price until the deductible is met, so comparing both prices at the counter is worth the extra minute. Just remember that discount card purchases will not count toward your deductible.

If you have coverage but it leaves gaps, NuLifeSpan Rx offers resources for people who are underinsured. Manufacturer copay cards are another tool for some brand-name drugs, and our comparison of copay cards and discount cards explains which one applies to your situation.

Frequently Asked Questions

How much is montelukast 10 mg without insurance?

As of October 21, 2026, generic montelukast 10 mg is listed from about $5.81 to $11.50 for 30 tablets at discounted cash prices, according to the Drugs.com price guide. Without a discount, average retail prices can be much higher, so compare prices with a discount card before you pay.

Is generic montelukast as effective as Singulair?

Generic montelukast contains the same active ingredient as Singulair and is FDA-approved as a therapeutic equivalent. The main difference is price: Singulair 10 mg is listed near $290 for 30 tablets, while the generic is listed under $12 for the same quantity.

Can I buy montelukast over the counter?

No. In the United States, montelukast requires a prescription in every form, including tablets, chewable tablets, and oral granules. If you have allergy symptoms, a healthcare provider can help you decide whether montelukast or another option is appropriate.

Why are montelukast oral granules more expensive than tablets?

Oral granules are a specialized form made for very young children and are used by fewer patients, which keeps prices higher. Generic granules are listed from about $45.51 for 30 packets, compared with about $5.81 for 30 adult tablets. Ask the prescriber whether a chewable tablet is suitable for your child’s age.

Does the NuLifeSpan Rx card work for montelukast?

The NuLifeSpan Rx card applies to eligible prescription medications at participating pharmacies, and savings vary by drug and pharmacy. Use the NuLifeSpan Rx pricing tool to see the price for your exact strength and quantity at pharmacies near you before you fill.

Is it cheaper to get a 90-day supply of montelukast?

Often, yes. The listed discounted cash price for 90 tablets of montelukast 10 mg starts near $8.25, which is only slightly more than many 30-day prices. Talk with your prescriber first if you are new to the medication, since a shorter trial may be safer at the start.

What is the FDA warning on montelukast?

Montelukast has an FDA boxed warning for serious neuropsychiatric events, including mood and behavior changes and suicidal thoughts or actions. For allergic rhinitis, the FDA recommends reserving montelukast for patients who do not respond well to, or cannot tolerate, other treatments.

Conclusion

The montelukast cost without insurance can be manageable for most people. Generic montelukast 10 mg is listed from under $6 for 30 tablets and under $9 for 90 tablets at discounted cash prices, while brand-name Singulair can cost hundreds of dollars per month. Choosing the generic, comparing pharmacy prices, and asking about a 90-day fill are the most reliable ways to keep your cost low.

Safety matters as much as price. Montelukast carries an FDA boxed warning, it is not a rescue treatment for asthma attacks, and for allergies it is generally reserved for people who have not done well on other options. Before starting, stopping, or switching any medication, talk with your prescriber or pharmacist, and use the NuLifeSpan Rx tools to check what your next fill should cost. Every eligible fill on a personalized card also earns cashback, which is a small but steady bonus for a medication you may take every day.
