Which companies make generic bupropion?
Multiple manufacturers produce generic versions of bupropion, but the exact list depends on the specific product type (most commonly bupropion hydrochloride immediate-release tablets, extended-release tablets, and sustained/extended-release versions). Generic products are commonly sold under multiple brand names and strengths, which means manufacturers can vary by dosage form and market.
How to check who makes a specific bupropion generic (IR vs XL/SR)
If you’re trying to identify the manufacturer for the exact tablet you’ll receive, check:
- The label’s “Manufacturer” or “Distributed by” line on the bottle/box
- The National Drug Code (NDC) printed on the product packaging. NDC-specific listings will map to the correct manufacturer for that exact strength and release type.
This matters because “bupropion generic” is a broad category, and different generics (immediate-release vs extended-release) often come from different companies.
Are there manufacturing “shortages” or switches between generic makers?
Generic products can switch suppliers over time due to capacity, regulatory actions, or supply disruptions. As a result, pharmacies may dispense a different manufacturer’s version of the same generic strength/release type even if the active ingredient and dosage match.

Quick clarification that affects the manufacturer list
Tell me which one you mean and I can narrow it down:
- bupropion immediate-release (IR) or extended-release (XL) or sustained-release (SR)?
- the strength (e.g., 75 mg, 100 mg, 150 mg, 200 mg)?
- if you have it, the NDC number from your bottle.
