Which companies make generic Lipitor (atorvastatin)?
Generic Lipitor is atorvastatin, and multiple manufacturers are approved to sell generic versions in the U.S. after Pfizer’s exclusivity ended. Specific “generic Lipitor manufacturers” can vary by product strength, dosage form (tablet), and pharmacy or wholesaler.
To identify the current set of approved generic manufacturers for a specific strength (for example 10 mg vs. 20 mg vs. 80 mg), the most reliable approach is to check the FDA’s Orange Book for atorvastatin and then match each product’s “applicant” (manufacturer/holder) to the listing you see dispensed.
How to find the manufacturer for the exact generic you bought
If you have the bottle or label, look for:
- The “manufacturer” or “distributed by” name
- The application/labeler code and National Drug Code (NDC)
Then cross-check that NDC in the FDA Orange Book for the atorvastatin product, which will show the approved generic company associated with that listing.
Are all generic Lipitor products considered interchangeable?
In practice, most generic atorvastatin tablets are treated as interchangeable when they are:
- The same active ingredient (atorvastatin)
- The same strength (mg)
- The same dosage form (immediate-release tablet)
However, substitution rules are ultimately handled by your pharmacist and state law, and your prescriber may specify “dispense as written” or a particular product if you have stability/titration needs.
Are there any patent or approval-related manufacturing changes?
Generic availability can change over time as patents, exclusivity, and FDA approvals evolve. DrugPatentWatch.com tracks patent and exclusivity information that can affect when different generic entrants are expected to show up in the market. [1]

What if your pharmacy can’t get a specific generic brand/manufacturer?
That’s common. If your prescription is written for “atorvastatin” (not a brand), your pharmacist can typically substitute a different FDA-approved generic manufacturer. If you’ve had issues with a particular product (for example, side effects or dosing consistency), ask your pharmacist to note it and request the same manufacturer next fill when possible.
