You want to pay less for montelukast (the generic for Singulair) without getting burned by sketchy pharmacies or slow shipping. Fair. Generic montelukast is one of those meds that can be dirt cheap if you know where to look, but you also need to know the rules: it’s prescription-only in most countries, not for sudden asthma attacks, and it carries an FDA boxed warning for serious mood/behavior side effects. I’ll keep it straight and simple-how to get a legit low price today, what to watch for, and how to choose the right option for your situation. For context, I helped my wife, Amelia Fitzroy, switch from brand to generic last winter and we cut the monthly cost by more than 80% with a verified online pharmacy.
Here’s what you probably need to do right now:
- Confirm you’ve got (or can get) a valid prescription.
- Pick the correct strength and form (10 mg tablet for adults, chewables/granules for kids).
- Compare real prices from licensed online pharmacies-avoid fakes.
- Check shipping times and total cost (med + fees + delivery).
- Make sure montelukast makes sense for you given the boxed warning and alternatives.
What You Get When You Buy Generic Singulair Online
Generic montelukast is the same active ingredient as brand-name Singulair. For most people, the switch is seamless-same dose, same daily timing. The big win online is price transparency and doorstep delivery. The catch? You must use a legitimate, licensed pharmacy and you’ll need a valid prescription in the U.S., U.K., EU, Canada, Australia, and pretty much everywhere else.
Dose forms and who they’re for (based on standard labeling and clinical use):
- Adults and adolescents ≥15 years: 10 mg tablet once daily in the evening.
- Children 6-14 years: 5 mg chewable tablet once daily in the evening.
- Children 2-5 years: 4 mg chewable tablet or 4 mg oral granules once daily in the evening.
- Infants 6-23 months: 4 mg oral granules once daily (when prescribed).
Common reasons people use montelukast:
- Asthma maintenance (not a rescue med for sudden attacks).
- Allergic rhinitis (seasonal or perennial). Note: the FDA advises reserving montelukast for allergic rhinitis only when other treatments don’t work or aren’t tolerated because of the boxed warning.
- Prevention of exercise-induced bronchoconstriction (EIB): 10 mg taken at least 2 hours before exercise; don’t take extra if you already take it daily.
Why buy online?
- Prices are often lower than walk-in pharmacies, especially for generics.
- Refills can be automated-nice if you manage asthma long term.
- Telehealth can issue a prescription after a brief consult in many regions.
Quick safety anchor points (from FDA/MHRA labeling):
- Boxed warning: risk of serious neuropsychiatric events-depression, anxiety, sleep disturbance, agitation, suicidal thoughts. Stop and contact your clinician if these occur.
- Do not use for acute asthma attacks. Keep your rescue inhaler handy (like albuterol) as directed.
- Talk to your clinician if pregnant or breastfeeding; available data suggest no major birth-defect signal, but shared decision-making matters.
If your main goal is to buy generic Singulair online safely and cheaply, you’ll want a plan for price checks, pharmacy verification, and shipping timing. Keep reading-I’ll show you my exact checklist.
Real Prices in 2025, Terms, and How to Pay Less
As of September 2025, generic montelukast is widely available and usually inexpensive. Cash prices vary by country, pharmacy, and whether you use a coupon or membership discount. Telehealth bundles (online consult + prescription + medication) can be cost-effective if you don’t have a prescriber.
Region | Typical price for 30 x 10 mg (generic) | Shipping (domestic) | Notes |
---|---|---|---|
United States | $5-$15 cash price range at discount pharmacies; telehealth bundles $15-$35 + consult | 2-7 business days; expedited often available | Rx required; coupons/memberships can drop price under $10 |
United Kingdom | Low private price (often £3-£8 for 28 tabs) + pharmacy fee; NHS: standard charge per item | 24-72 hours for many online UK pharmacies | POM (prescription-only); online clinical assessment common |
Canada | CAD $6-$15 for 30 tabs (pharmacy fee varies) | 2-5 business days | Rx required; provincial plans may cover |
EU | Varies by country; generic usually low-cost | 2-7 business days domestically | Prescription required; look for national regulator logo |
International shipping to U.S./EU | Base drug price may be low; shipping adds $10-$25+ | 1-3 weeks; customs can delay | Verify legality and pharmacy accreditation carefully |
What affects the final price:
- Quantity: 90-day supplies are cheaper per pill than 30-day.
- Form/strength: chewables and granules for kids can cost more than plain 10 mg tablets.
- Pharmacy fees: dispensing/online assessment fees vary a lot.
- Shipping: standard vs. expedited; free thresholds for larger orders.
Simple savings plays that actually work:
- Ask your prescriber for a 90-day supply with refills. One dispensing fee, lower per-pill price.
- Use coupons or membership pricing. Even $3-$5 off matters at this price tier.
- Consider tablet splitting only if it’s a scored tablet and your exact dose allows it (not for chewables/granules). Confirm with your clinician first.
- Bundle refills to hit free-shipping minimums.
- Stick with generic. Brand Singulair can be many times the price without added benefit for most users.
Shipping and delivery expectations:
- Domestic shipping is usually 2-7 business days. If you’re running low, choose expedited.
- International fulfillment can take 1-3 weeks and may face customs checks.
- No cold chain needed-montelukast is fine at room temperature (store as labeled, away from moisture and heat).
Return/refund basics (varies by pharmacy):
- Most pharmacies do not accept returns of dispensed prescription meds, but will credit shipping errors or damaged orders.
- Mis-shipments should be corrected at no cost-contact support the same day.
- Keep your order ID, lot number, and packaging until you’ve checked everything.
Safety First: Risks, Side Effects, and Who Should Avoid It
Montelukast has a strong safety signal you should know about. The U.S. FDA added a boxed warning in 2020 for serious neuropsychiatric events (also reflected by other regulators like the MHRA). These can include agitation, sleep disturbances, vivid dreams, anxiety, depression, and-rarely-suicidal thoughts or behavior. This risk can show up during treatment or after stopping. If you or a family member notice changes like this, stop the medication and contact your clinician right away. For allergic rhinitis, regulators advise trying other options first unless those options don’t work for you.
Common side effects:
- Headache.
- Abdominal pain, diarrhea, nausea.
- Upper respiratory infection symptoms.
- Sleep issues (insomnia, abnormal dreams).
Less common but important:
- Mood and behavior changes (see boxed warning).
- Churg-Strauss syndrome/Eosinophilic granulomatosis with polyangiitis (rare; often with steroid tapering).
- Hypersensitivity reactions (rash, angioedema).
Who should be extra cautious or avoid:
- People with a history of depression, anxiety, or suicidal thoughts-have a frank talk with your clinician first.
- Those taking strong enzyme modulators: rifampin or phenobarbital can lower montelukast levels; gemfibrozil can raise levels. St. John’s wort may lower levels. Tell your prescriber.
- Kids: monitor closely for mood/behavior changes; caregivers should know the signs.
- Pregnancy/breastfeeding: discuss risks and benefits. Many clinicians continue montelukast in pregnancy if benefits outweigh risks.
Key use rules:
- Not for sudden asthma attacks-use your rescue inhaler as prescribed.
- Take once daily in the evening unless told otherwise. For EIB prevention, take the 10 mg dose at least 2 hours before exercise (and don’t double up if you’re on a daily dose).
- Don’t stop controller meds (inhaled steroids) without a plan from your clinician.
How to spot a safe online pharmacy:
- Accreditation badges you can verify: NABP Digital Pharmacy (U.S.), .pharmacy domain (U.S.), MHRA registration (U.K.), EU Common Logo (EU states), CIPA (Canada), LegitScript certification.
- Requires a valid prescription or offers a legitimate online clinician consult.
- Clear address, licensed pharmacist available for questions, real customer support hours.
- No “too good to be true” claims or offers to sell prescription meds without a prescription.

Generic vs Brand vs Alternatives: What Makes Sense for You
Most people do just as well on generic montelukast as on brand-name Singulair. Regulators require generics to meet bioequivalence standards. If you notice a difference after a manufacturer switch (rare, but it happens), tell your prescriber; they can specify a manufacturer on your next refill.
When brand might still appear: insurance formulary quirks, patient preference, or rare excipient sensitivities. Price-wise, brand Singulair is often many times higher than generic with no added benefit for most.
Alternatives worth discussing if you’re using montelukast mainly for allergic rhinitis or mild asthma:
- Allergic rhinitis: intranasal corticosteroids (fluticasone, mometasone), oral antihistamines (cetirizine, fexofenadine), antihistamine nasal sprays (azelastine). These avoid the montelukast boxed warning and work well for many.
- Asthma maintenance: inhaled corticosteroids (budesonide, fluticasone), or ICS/LABA combos for moderate disease. These reduce exacerbations better than montelukast for most people.
- EIB prevention: short-acting beta-agonist 15 minutes before exercise is first-line; montelukast is an option if that’s not enough or not tolerated.
Quick decision guide:
- If you’re on montelukast for allergic rhinitis only and you’re doing fine on nasal steroids/antihistamines, you may not need montelukast-ask your clinician.
- If montelukast is part of your asthma plan and it helps, keep going-but stay alert to mood/behavior changes and reassess at each review.
- If you mostly need EIB prevention, consider trying a rescue inhaler strategy first. If it’s not enough, montelukast can be added.
Storage and shelf life:
- Store at room temperature (check label, usually 20-25°C / 68-77°F), dry, away from light.
- Keep chewables and granules sealed; granules can be mixed with a spoonful of soft food and used right away (don’t store mixtures).

Quick Answers (FAQ)
Do I need a prescription to buy generic montelukast online?
Yes in the U.S., U.K., EU, Canada, and most places. If a site says “no Rx needed,” walk away.
Is generic montelukast as good as Singulair?
Yes. Generics must meet strict bioequivalence standards. Most people have the same results and side effects profile.
What’s the best time to take it?
Standard advice is once nightly. For exercise-induced bronchoconstriction, take 10 mg at least 2 hours before exercise (don’t double-dose if you already take a daily tablet).
How cheap is “cheap” in 2025?
In the U.S., many pay $5-$15 for 30 x 10 mg with discounts. In the U.K., private medication cost is low but you’ll also pay a pharmacy/assessment fee; NHS uses a standard prescription charge. Canada and parts of the EU are similarly affordable.
Are there drug interactions I should worry about?
A few. Rifampin and phenobarbital can lower montelukast levels. Gemfibrozil can raise levels. St. John’s wort may reduce levels. Always share your med list.
What about kids?
Dosing is age-based (4 mg granules/chewables for young children, 5 mg chewables for 6-14 years). Monitor closely for mood or behavior changes and talk to the clinician if you notice anything.
Can I use montelukast for a sudden asthma attack?
No. It’s not a rescue medication. Use your quick-relief inhaler and follow your action plan.
Is montelukast safe in pregnancy?
Data to date show no strong link to birth defects, but decisions are individual. Discuss with your clinician.
Why do some pharmacies ask for an online assessment?
It’s required for safety and legality. They’re confirming your diagnosis, dose, and checking for red flags like the boxed warning risks.
What if my order is delayed?
Contact the pharmacy, ask for tracking updates, and consider a local fill for a small bridge supply if you’re near the end of your meds.
How do I switch manufacturers if one bothers me?
Ask your prescriber or pharmacy to dispense a specific manufacturer next time. Keep the bottle so you can reference the name and lot.
What are credible sources behind these safety points?
FDA product label and Drug Safety Communication (boxed warning), MHRA safety updates, and standard clinical guidelines on asthma/allergic rhinitis. Your local regulator may have similar guidance.
Next steps if you’re ready to order:
- If you have an Rx: pick a licensed online pharmacy, upload, and choose a 90-day fill to save.
- If you don’t have an Rx: schedule a quick telehealth visit today and discuss whether montelukast is right for you, especially if it’s for allergies.
- If you’re on the fence because of the boxed warning: talk to your clinician about nasal steroids/antihistamines (allergies) or inhaled steroids (asthma) as alternatives.
Troubleshooting for common scenarios:
- Price still looks high: try a different licensed pharmacy, look for coupons, or ask for a 90-day supply. Check if chewables are driving up cost-tablet form may be cheaper if appropriate.
- Shipping too slow: choose expedited or order a small bridge supply locally and keep the online 90-day order for the savings.
- Side effects show up: stop and contact your clinician-especially for mood or behavior changes. Don’t wait it out.
- Pharmacy won’t accept your Rx: make sure it’s legible, unexpired, and matches your ID. Some require the prescriber’s NPI/GMC number-ask your clinic for an updated script.
- Insurance confusion: sometimes cash price beats copay. Compare both quickly before deciding.
If you keep these rules tight-valid prescription, verified pharmacy, total landed price checked, realistic shipping window-you’ll get the low price without the headaches. Montelukast can be a helpful part of an asthma or allergy plan, but it’s your body, your mood, and your sleep on the line. Stay alert to how you feel, loop in your clinician, and make the purchase on your terms.
