Montelukast is a leukotriene receptor antagonist that reduces inflammation in the airways, making it a cornerstone treatment for asthma and allergic rhinitis. The drug is sold worldwide under the brand name Singulair, but generic versions are widely available and cost a fraction of the branded price. If you’re looking to cheap generic Singulair online, you need to know the right questions to ask, where to shop, and how to protect yourself from counterfeit medication.
Why Choose Generic Montelukast?
Generic versions contain the same active ingredient, dosage strength, and therapeutic effect as the brand-name product. In the UK, the Medicines and Healthcare products Regulatory Agency (MHRA) requires that generics meet strict bio‑equivalence standards, meaning they deliver the same blood concentration as Singulair within a 10‑percent margin. The main advantages are:
- Price: generic packs can be 60‑80% cheaper than the brand.
- Availability: many online pharmacies keep a steady stock, even when the brand is back‑ordered.
- Flexibility: you can choose tablets, chewable tablets, or granules depending on age and preference.
How Montelukast Works in the Body
When you inhale an allergen, your immune system releases leukotrienes-chemicals that cause the airway muscles to tighten and the lining to swell. Montelukast blocks the leukotriene‑D₄ receptor, preventing these reactions. The result is smoother breathing, fewer night‑time coughs, and reduced reliance on rescue inhalers.
Clinical data from over 20,000 patients show an average 30% reduction in asthma exacerbations for anyone taking a daily 10mg dose. For children with allergic rhinitis, chewable tablets (4mg) improve symptom scores by roughly 25% compared to placebo.
When It Makes Sense to Buy Online
Buying medication online can be a smart move if you meet any of these conditions:
- You have a valid prescription from a UK‑registered GP or a telehealth provider.
- You’ve checked that the pharmacy is licensed by the MHRA and appears on the GPhC Register of Online Pharmacies.
- You’re comfortable receiving medication by post and have a secure delivery address.
If any of these points feel shaky, pause and verify before proceeding. Illicit sites often lure shoppers with “no prescription needed” claims, which is a red flag.
Finding Legitimate Cheap Sources
Here’s a step‑by‑step guide to locate trustworthy, low‑cost options:
- Search for "online pharmacy" + "MHRA licensed" in your preferred search engine.
- Open the pharmacy’s website and look for the MHRA seal or a link to the GPhC register.
- Check the "About Us" page for a physical address and a UK‑registered pharmacy licence number.
- Compare the listed price of generic montelukast (usually shown per 30‑tablet pack) with at least two other sites.
- Read recent customer reviews on independent forums (e.g., Reddit’s r/ukpharmacy) to gauge delivery speed and product quality.
- Use a secure payment method such as a credit card or PayPal, which offers buyer protection.
Many UK residents also benefit from discount codes offered by loyalty programmes or health‑insurance providers. Keep an eye out for seasonal sales-December and July often bring 10‑15% off.

Price Comparison: Generic vs Brand vs Alternatives
Product | Typical Price (30 tablets) | Formulation | FDA/MHRA Approval Year | Common Dose |
---|---|---|---|---|
Generic Montelukast | £4.99 | Tablet 10mg, Chewable 4mg | 1998 (FDA), 1999 (MHRA) | 10mg daily (adults), 4mg daily (children) |
Singulair (brand) | £20.95 | Tablet 10mg, Chewable 4mg | 1998 (FDA), 1999 (MHRA) | Same as generic |
Zafirlukast (alternative) | £12.50 | Tablet 20mg | 2001 (FDA) | 20mg twice daily |
The table shows that the generic version slashes the price by roughly 75% compared with Singulair, while still delivering the exact same therapeutic effect. Zafirlukast is another leukotriene antagonist but requires twice‑daily dosing, which many patients find less convenient.
Safety, Side Effects, and Drug Interactions
Montelukast is generally well‑tolerated. The most commonly reported side effects (affecting less than 5% of users) are:
- Headache
- Stomach pain
- Rare mood changes (especially in adolescents)
Because the drug is metabolised by the liver enzyme CYP3A4, be cautious when you’re also taking:
- Rifampicin
- Ketoconazole
- Some HIV protease inhibitors
If you’re on these medicines, your doctor may adjust the dose or suggest an alternative. Always share your full medication list with the prescribing clinician and with the online pharmacy’s pharmacist (many offer a live chat).

Frequently Asked Questions
Can I buy generic montelukast without a prescription?
In the UK, montelukast is a prescription‑only medicine (POM). Legit online pharmacies will ask for a valid UK prescription or a telehealth consult before dispensing. Sites that claim “no prescription needed” are likely operating illegally and may sell counterfeit products.
Is generic montelukast as safe as the brand?
Yes. The MHRA requires generic medicines to demonstrate bio‑equivalence to the brand, meaning the active ingredient is delivered to the bloodstream in the same amount and at the same rate. Clinical outcomes are indistinguishable when you follow the prescribed dose.
How much does a 30‑tablet pack of generic montelukast cost in the UK?
Prices vary by pharmacy, but most reputable online retailers list it between £4.99 and £7.50 per pack. Seasonal discounts or loyalty codes can push the price closer to £4.00.
What should I do if I receive the wrong medication?
Contact the pharmacy immediately and request a full refund and a replacement. Keep the packaging and any leftover tablets; they may be needed for a formal complaint to the MHRA. Do not consume the product until you receive confirmation that it is correct.
Are there any age restrictions for using generic montelukast?
The tablet 10mg is approved for adults and children aged 12years and older. For younger children (2‑11years), the 4mg chewable tablet is the recommended form. Always follow the pediatric dosing chart provided by your GP.
Can I use montelukast together with an inhaled corticosteroid?
Yes. In fact, many treatment plans combine a leukotriene antagonist with an inhaled corticosteroid to achieve better control of persistent asthma. Your doctor will tailor the regimen based on severity and lifestyle.
