Where is bupropion manufactured?
Bupropion is manufactured by multiple companies across different countries, depending on the specific product (brand vs. generic), dosage form, and the supplier that fills that manufacturer’s label.
Why you might see different answers by brand or generic
Even though “bupropion” is the same active ingredient, individual manufacturers produce different versions (for example, immediate-release vs. extended-release). Each manufacturer’s facility location can differ, so the country of manufacture is not one universal place for all bupropion products.
How to find the exact manufacturing location for your specific pill
The most reliable way is to check the package labeling for:
- “Manufactured for” (or “Manufactured by”) and the company name
- The company’s address listed on the label
- Any “Distributed by” vs. “Manufactured by” wording (these are often different)
If you share the exact product name (brand/generic), strength (e.g., 150 mg), and whether it’s SR/XL/IR, I can help you narrow down which manufacturer is most likely associated with that version.
Can manufacturers change over time?
Yes. Companies can switch contract manufacturers or move production between plants as supply, costs, or regulatory approvals change, so the “manufactured in” location can vary across batches.
