Where is montelukast made (and by which companies)?
Montelukast (the active ingredient in drugs such as Singulair and generics) is manufactured in multiple locations globally, depending on the specific product, dosage form, and manufacturer. Because the tablet or granule blend is produced by different companies under different supply contracts, the manufacturing site can vary by brand and by generic version.
How can I find the exact manufacturing location for the specific product I have?
The most reliable way is to check the package insert or the label for your specific brand/generic. Look for wording such as “Manufactured by,” “Manufacturing site,” or “Address of manufacturer,” which usually identifies the site or company responsible for that particular product batch.
Why do answers online differ?
Search results often mix:
- the company that developed the drug,
- the company that supplies the active ingredient (API),
- the company that makes the finished tablets, and
- the country where the product is sold.
Those are not always the same, which is why manufacturing locations can appear inconsistent across sources.
What if you tell me your brand and country?
If you share the exact product name (brand or generic), strength (e.g., 10 mg or 4 mg), and what country you’re in, I can help you narrow down the likely manufacturing details to the product’s listed manufacturer and site.
