Generic Singulair is a montelukast sodium tablet that treats asthma and allergic rhinitis at a fraction of the brand price. If you’ve typed cheap generic Singulair into a search box, you’re probably looking for a reliable way to get the medication without draining your wallet. This guide walks you through what the drug does, why price gaps exist, and the exact steps to order it safely from a UK‑based online pharmacy.
What Is Montelukast and How Does It Work?
Montelukast Sodium is the active ingredient in both the brand‑name Singulair and its generics. It belongs to the leukotriene‑modifier class, blocking chemicals that cause airway inflammation. Typical doses are 10mg for adults and 4mg for children, taken once daily in the evening. Clinical data show a 20‑30% reduction in nighttime asthma symptoms compared with placebo.
Key Conditions Treated
- Asthma - chronic airway narrowing that triggers wheezing and shortness of breath.
- Allergic Rhinitis - hay‑fever symptoms such as sneezing, runny nose, and itchy eyes.
Both conditions are listed on the FDA label for montelukast, meaning the drug is approved for these uses worldwide, including the UK.
Why Are Generic Versions Cheaper?
The price gap comes from three factors:
- Manufacturers don’t bear the branding and marketing costs that the original company did.
- Regulatory pathways for generics are streamlined; they only need to prove bio‑equivalence.
- Large‑scale production drives down the Cost Savings per tablet, often by 50‑70%.
In the UK, a 30‑day course of generic montelukast can cost under £5, whereas the branded version may exceed £15.
How to Verify a Safe Online Pharmacy
Not every website you stumble upon is legit. Use these three checks:
- Look for a UK‑registered pharmacy number (e.g., “GPhC 12345”). The General Pharmaceutical Council (GPhC) maintains an online register.
- Confirm that a Prescription Requirement is enforced. Even in the UK, montelukast is prescription‑only; any site offering it without a valid prescription is a red flag.
- Check for clear Bioavailability data - generic tablets must match the brand’s 90‑95% bio‑equivalence rate.
Step‑by‑Step: Buying Cheap Generic Singulair Online
- Obtain a valid prescription from your GP or a tele‑health service that complies with NHS standards.
- Search for a GPhC‑registered pharmacy that lists “Montelukast Sodium” among its products.
- Compare prices using the table below; add the cheapest option to your cart.
- Enter your prescription details securely - many UK sites allow you to upload a scanned PDF.
- If the pharmacy offers a “direct dispense” service, they’ll send the medication straight to your address.
- Choose a delivery option (standard 3‑5business days is usually free for orders under £20).
- Confirm the order, keep the receipt, and store the medication as advised (room temperature, dry place).

Price Comparison: Generic vs Brand vs Other Leukotriene Inhibitors
Product | Price per 30‑day supply (UK) | Regulatory status | Dosage forms | Bio‑equivalence |
---|---|---|---|---|
Generic Singulair | £4.80 | GPhC‑approved generic | 10mg tablet | 90‑95% |
Brand Singulair | £15.60 | Original MAH, FDA/EMA approved | 10mg tablet, chewable 4mg | Reference |
Zafirlukast (Accolate) | £9.20 | GPhC‑approved | 20mg tablet | Comparable |
Additional Savings Tips
Beyond picking the cheapest generic, you can stretch your budget further:
- Use NHS prescription pre‑payment certificates if you need multiple repeat prescriptions.
- Look for bulk‑order discounts - buying a 90‑day supply often reduces the per‑tablet cost by another 10‑15%.
- Check if your local pharmacy offers a “clinic‑dispense” service that matches online prices.
- Subscribe to reputable pharmacy newsletters; they occasionally share coupon codes for generic inhalers or leukotriene blockers.
Safety and Side‑Effect Profile
Montelukast is generally well‑tolerated, but be aware of:
- Rare neuropsychiatric effects (mood changes, agitation).
- Possible liver enzyme elevation - monitor if you have pre‑existing liver disease.
- Interaction with ritonavir and certain antifungals; always disclose all medicines to your prescriber.
If any side‑effect persists beyond two weeks, contact your GP or the pharmacy’s clinical team.

Frequently Asked Questions
Is it legal to buy generic Singulair without a prescription in the UK?
No. Montelukast remains a prescription‑only medicine. Any reputable online pharmacy will ask for a valid NHS or private prescription before dispensing.
How can I tell if an online pharmacy is GPhC‑registered?
Visit the General Pharmaceutical Council’s register (search by pharmacy name or registration number). Legit sites display the registration number prominently on their footer.
What’s the typical price difference between brand and generic Singulair?
The generic version costs roughly 30‑35% of the brand price, translating to a £10‑£12 saving per 30‑day supply in the UK.
Are there any hidden fees when ordering from an online pharmacy?
Reputable UK pharmacies disclose all costs upfront, including delivery. Beware of sites that add “processing” or “admin” fees after checkout - they often indicate a non‑compliant operation.
Can I use the same prescription for both brand and generic versions?
Yes. The prescription lists the active ingredient (montelukast) and dosage, not the brand name. Your pharmacist can dispense either version.
How long does delivery usually take?
Standard UK delivery is 3‑5 business days. Many pharmacies offer expedited shipping for an extra charge, but it’s rarely needed for a routine prescription.
What should I do if I receive the wrong medication?
Contact the pharmacy immediately, keep the product unopened, and request a replacement or refund. If the pharmacy is unresponsive, report the incident to the GPhC.
