How Much Is Montelukast (Singulair) Without Insurance? 2026 Cash Prices and How to Pay Less

Montelukast (Singulair) without insurance usually costs about $6 to $25 for 30 generic 10 mg tablets in 2026. Pharmacy price guides put the low end near $6 to $11.50, and free discount cards typically land between $8 and $25. Brand-name Singulair runs closer to $290 a month.

TL;DR: Key Takeaways

• The working range for the montelukast cost without insurance is roughly $6 to $25 for a 30-day supply of generic 10 mg tablets.
• The "average retail" figures of $62 to $145 a month you see quoted measure undiscounted list pricing, not what a cash payer actually hands over.
• Filling the generic instead of brand Singulair (about $290 a month) saves more than any coupon strategy will.
• Price is set per pharmacy, per fill. Calling two or three pharmacies is worth more than an hour of online research.
• Since the FDA's 2020 boxed warning, montelukast is not a first-choice drug for hay fever. If that is why you are filling it, ask whether a cheaper drugstore option fits.

How much is montelukast (Singulair) without insurance in 2026? Usually $6 to $25 a month

The montelukast cost without insurance in 2026 runs roughly $6 to $25 for 30 tablets of the generic 10 mg strength, which is the standard adult dose. The Drugs.com price guide lists cash prices of about $6 to $11.50 for that quantity, while GoodRx quotes $8 to $25 for a 30-day supply. Brand Singulair sits far above both figures.

Pediatric forms are a separate question, and parents who assume the child's version costs less than the adult tablet are usually wrong.

Every figure above is a 2026 range rather than a fixed price. It moves with your ZIP code, the specific pharmacy, the quantity dispensed and whichever discount program is applied at the register that day.

The "average retail price" you saw quoted is not your price

Published quotes for the montelukast 10mg price cover the same 30 tablets and still range from about $6 to about $145, depending entirely on whose number you happen to be reading.

The gap is methodological, not mysterious. National averages are built from undiscounted list and usual-and-customary data, which is the sticker price almost nobody pays for a mature generic. The low figures are what a person walking in off the street pays once a free card is applied. Same drug, same quantity, two entirely different measurements. The same spread shows up in other everyday generics, including how much amoxicillin costs without insurance.

Here is what most pages will not tell you: no single national "without insurance" figure applies to you personally. The price is set at the counter, by that pharmacy, on that fill. Your job is comparison-shopping, not number-lookup.

Almost all of the savings come from one thing: filling the generic

The generic montelukast price of roughly $6 to $25 for 30 tablets sits against $289 to $291 a month for brand-name Singulair, which makes generic substitution the single largest lever available to you. Nothing else on this page comes close.

Montelukast has been available generically for well over a decade, and the overwhelming majority of US prescriptions are now dispensed that way. The generic contains the same active ingredient at the same strength. Paying brand pricing for it is almost always an administrative accident rather than a clinical decision.

So check the bottle. If your prescription or your current label says Singulair, ask the pharmacist to substitute the generic and re-price it before you pay. That one question, asked at the counter, is worth more than every coupon in your inbox. In most states the pharmacist can make the swap without calling your prescriber, and the generic montelukast price you get back is the number that should decide the fill.

Manufacturer assistance for Singulair is a dead end for most patients

If you are trying to lower the Singulair price without insurance, a manufacturer program is usually the wrong place to spend your time. Merck's patient assistance program applies to brand-name Singulair, not to generic montelukast, so it does nothing for the majority of people whose prescription is filled as the generic.

That is also why the Drugs.com price guide reports no manufacturer coupon or assistance program found for montelukast while other sites list Merck's program. Both are correct. One is describing the generic and the other the brand. Read the label on your bottle before you fill out any application.

Your regular pharmacy is probably not the cheapest one

The cheapest pharmacy for montelukast changes by ZIP code and by fill date, which means it has to be checked rather than assumed. Warehouse and grocery pharmacies (Costco, Walmart, Kroger and similar regional grocery chains) tend to post low straight cash prices because their pharmacy is a traffic driver, not a profit center. Large drugstore chains like CVS and Walgreens often carry a higher shelf cash price but become competitive once a discount card or their own savings program is applied.

Realistically, you are looking for something in the $6 to $11.50 band at the low end, or $8 to $25 with a card. Anything materially above that should prompt a second call.

Ask exactly this: "What is your cash price for thirty 10 mg montelukast tablets, and what is it with your best discount price?" Get the quote by phone or in the pharmacy's app the same day you plan to fill. If another pharmacy is cheaper, transferring the prescription is free and usually takes one phone call to the new pharmacy.

How to pay the lowest price: five steps, in order

A free montelukast coupon or discount card belongs third in this sequence, not first, because the two steps ahead of it move more money. Discount cards are free to use and require no insurance, and on any single fill you use the card price or your insurance, not both.

Before any of it: montelukast is prescription-only in the United States, so without a current prescription your first cost is the visit, not the drug, and clinic pricing varies widely (see what an urgent care visit costs). August connects you with a US-licensed clinician who reviews your symptoms and decides whether montelukast or a different treatment is appropriate. What that visit cannot do is treat an asthma attack in progress. That is an emergency, not a telehealth appointment.

• Confirm you are filling generic montelukast, not brand Singulair.
• Get cash quotes from two or three pharmacies, including at least one warehouse or grocery pharmacy.
• Apply a free discount card at your best-quoted pharmacy and ask them to re-price the fill.
• Ask what a 90-day supply costs per tablet. Larger fills usually lower the per-tablet price and cut repeat dispensing fees, but ask rather than assume.
• Only if you are specifically prescribed brand Singulair, look into manufacturer assistance.

Before you pay anything, ask whether you should be on montelukast at all

On March 4, 2020, the FDA required a boxed warning, its most serious warning, on montelukast for suicidal thoughts or actions, depression, anxiety, agitation and other serious neuropsychiatric events.

The practical consequence is a pricing consequence too. The FDA advises that for allergic rhinitis, montelukast should be reserved for people who are not treated effectively by, or cannot tolerate, other allergy medicines. If you are paying cash for hay-fever relief, ask your clinician about over-the-counter cetirizine or loratadine, or a steroid nasal spray such as fluticasone, which are frequently cheaper and carry no comparable warning. For asthma, prescribers weigh the risk case by case and there is no blanket restriction.

One clinical point that changes what you buy: MedlinePlus notes montelukast is taken once daily, in the evening when it is prescribed for asthma, and it is not a rescue medication. It will not stop an attack already underway, so it never replaces a rescue inhaler in your budget.

Call 911 or your local emergency line or go to an emergency room now if:

• You have new or worsening suicidal thoughts, self-harm behavior, or you have attempted suicide. You can also call or text 988 to reach the Suicide and Crisis Lifeline.
• Sudden severe agitation, aggression, hallucinations or confusion begins after starting the drug.
• You have swelling of the face, lips, tongue or throat, trouble breathing, or hives.
• You have a sudden asthma attack or severe breathing difficulty. Montelukast is not a rescue medication. Use a fast-acting rescue inhaler and get emergency care if symptoms do not resolve.

Book a visit within the next week if:

• You or your child has had mood, sleep or behavior changes since starting montelukast.
• You are taking montelukast for seasonal allergies only.
• You are rationing doses because of cost.

Talk to a physician before you start if:

• You have a history of depression, anxiety or suicidal thoughts.
• The prescription is for a child.
• You have not yet tried an over-the-counter antihistamine or steroid nasal spray.

The bottom line on montelukast prices without insurance

Work from about $6 to $25 for 30 generic 10 mg tablets, not the $62 to $145 "average retail" figures. The highest-value thing you can do today is call two or three pharmacies, including a warehouse or grocery pharmacy, then re-quote with a free discount card. If you take montelukast for allergies alone, raise the 2020 boxed warning with your clinician and ask whether a cheaper over-the-counter option is the better fit. With 32% of uninsured adults under 65 very worried about affording their prescriptions, that price-shopping habit is the response.
