Where is Trelegy manufactured (and which parts)?
Trelegy (a combination inhaler containing fluticasone furoate, umeclidinium, and vilanterol) is manufactured by GlaxoSmithKline (GSK). The specific manufacturing sites can vary by product strength and packaging, and they can change over time as production is adjusted.
What locations are listed on packaging or regulatory filings?
The most reliable way to confirm the exact factory for the particular Trelegy product you have is the label/box for your specific lot. Manufacturing site information is typically shown as a “manufactured by” or “distributed by” entry on the carton, along with address details tied to that product.
How can you find the exact plant for your Trelegy lot?
Look for:
- The “Manufactured by”/“Manufactured for” line on the carton or blister/label
- The address associated with that manufacturer
- The lot number, which you can match to the regulatory/listing information for that specific product presentation
Who makes it in the supply chain?
GSK markets and supplies Trelegy, but the product’s contracted manufacturing and packaging steps may involve different facilities.

If you tell me your exact product, I can narrow it down
If you share the strength (Trelegy Ellipta 100/62.5/25 mcg or 200/62.5/25 mcg) and what’s written on your box under “manufactured by/for” (or the lot number), I can help identify the manufacturing location listed for that specific version.
