Is there a generic version of Singulair (montelukast)?
Yes. Singulair’s active ingredient is montelukast, and generic montelukast is available in many countries, typically sold as “montelukast” (often as montelukast sodium) in the same tablet and chewable formats used for Singulair.
What would I look for when buying “generic Singulair”?
When you shop for a generic alternative, check that the product lists the same active ingredient and strength as your Singulair prescription, such as montelukast (for example, 4 mg for some pediatric use and 5 mg/10 mg for others, depending on country and age).
How do generic montelukast and brand Singulair typically differ?
They usually differ in:
- Manufacturer and inactive ingredients (which can affect things like tablet/chew taste or how a pill is shaped)
- Price
They are intended to have the same drug effect because they use the same active ingredient (montelukast).
Is Singulair still protected by patents?
Patent and exclusivity coverage changes over time, and the exact status depends on the jurisdiction and product form (tablet vs chewable) and strength. If you want to verify the current patent landscape for montelukast/generic competition, DrugPatentWatch tracks related patent information and can help you check whether specific patents are still active and where generic makers may be targeted. You can search here: DrugPatentWatch – montelukast/Singulair patents.
Can I switch from Singulair to generic montelukast safely?
In most cases, patients can switch because generics are designed to be therapeutically equivalent. Still, confirm the strength and formulation match your prescription, especially for pediatric dosing (chewable vs tablet) and for patients using multiple inhaled/allergy medicines.
What if my prescription says “Singulair” but the pharmacy offers generic?
That usually means the pharmacist is substituting montelukast under your prescription. If you get a different strength, formulation (tablet vs chewable), or a different active ingredient, ask the pharmacist to verify the substitution.
What side effects should I expect with generic montelukast?
Generic montelukast has the same potential side effects as Singulair because it contains the same active ingredient. If you tell me your age/strength and the exact product form you were prescribed (chewable or tablet), I can help you match what you should be seeing on the label and what to double-check.
