TL;DR: Look for FDA‑registered online pharmacies, compare generic Montelukast prices, use coupons or insurance, and double‑check dosage and side‑effects before you buy online cheap generic Singulair.
What Is Generic Singulair?
Generic Singulair is a leukotriene receptor antagonist (LTRA) that reduces inflammation in the airways, used to treat asthma and allergic rhinitis. The active ingredient is Montelukast, the same molecule found in the brand‑name drug Singulair.
Understanding Montelukast and Its Therapeutic Class
Montelukast is the generic name for the compound originally patented by Merck in 1994 and approved by the FDA in 1998. It belongs to the Leukotriene receptor antagonist class, which works by blocking leukotrienes-chemicals that trigger bronchoconstriction and mucus production.
Why People Look for Cheap Options
Brand‑name Singulair can cost $150-$200 for a 30‑day supply, while a generic version often drops below $30. High out‑of‑pocket costs push patients to search for online deals, especially those without robust insurance coverage.
Spotting a Legitimate Online Pharmacy
Online pharmacy is any website that dispenses prescription medication to consumers via the Internet. To ensure safety:
- Check for a valid FDA or National Association of Boards of Pharmacy (NABP) accreditation (look for the .Pharmacy or VIPPS seal).
- Verify that the pharmacy requires a prescription-any site offering medication without one is a red flag.
- Read the privacy policy; reputable pharmacies protect patient data and use encrypted checkout.
Price Comparison: Generic vs. Brand vs. Other LTRAs
Medication | Form | Typical Retail Price (USD) | Insurance Coverage |
---|---|---|---|
Brand Singulair | 10mg tablet | $150-$200 | Usually covered, higher co‑pay |
Generic Singulair (Montelukast) | 10mg tablet | $20-$35 | Often covered, low co‑pay |
Zafirlukast (Accolate) | 20mg tablet | $80-$120 | Limited formularies |
The table shows why generic Montelukast is the go‑to choice for most patients looking to save money while keeping the same clinical effect.

How to Get the Best Deal
- Use price‑comparison tools (e.g., GoodRx, Blink Health) to see real‑time discounts.
- Check if your Insurance coverage offers a preferred generic tier.
- Look for manufacturer coupons or patient assistance programs; sometimes the brand offers a free‑month coupon that beats generic pricing.
- Consider buying a 90‑day supply; many online pharmacies reduce the per‑day cost by 15‑25%.
- Verify the pharmacy’s return policy-legitimate sites will accept returns for unopened medication.
Safety First: Side Effects and Dosage
Montelukast is generally well‑tolerated, but you should be aware of common and rare reactions.
- Common: headache, stomach pain, cough, fatigue.
- Rare but serious: mood changes, depression, suicidal thoughts. If you notice any sudden mood shift, contact your doctor immediately.
The usual adult dose is 10mg once daily, taken with or without food. Pediatric dosing varies by weight; a pediatrician will prescribe the exact amount.
Legal and Regulatory Landscape
The FDA monitors generic drug approvals to ensure they meet bioequivalence standards. Since 2007, generic Montelukast has been on the market, and multiple manufacturers-including Teva, Mylan, and Sandoz-produce it. This competition drives the low prices you see online.
Common Pitfalls and How to Avoid Them
- Counterfeit meds: Avoid sites that offer “ultra‑cheap” prices far below market average. If a deal looks too good to be true, it probably is.
- Expired inventory: Reputable pharmacies list expiration dates; always check before confirming your order.
- Missing prescription verification: Some sites claim to “handle the prescription” for you. Only use a pharmacy that asks for a valid, uploaded prescription from a licensed provider.
Next Steps for Readers
After you’ve identified a trustworthy online pharmacy, follow these three steps:
- Upload your prescription: Use a secure portal; most sites accept a photo or PDF.
- Confirm dosage and quantity: Double‑check that the order matches your doctor’s instructions.
- Track shipping: Choose a shipping method with tracking; many pharmacies offer discreet packaging.
Once your medication arrives, store it at room temperature, out of direct sunlight, and keep it out of reach of children.
