Are atorvastatin and Lipitor the same medicine?
Yes. Lipitor is the brand name for the drug atorvastatin. They contain the same active ingredient, so the prescription medicine effect comes from atorvastatin itself, not the brand name.
What’s the difference, then—brand vs generic?
The main differences are usually non-medicinal: the brand (Lipitor) may cost more and can come from a single manufacturer, while generic atorvastatin is marketed by multiple manufacturers once it has regulatory approval. The dose strength is the key match point (for example, both may be 10 mg or 20 mg), and the tablet formulation can differ slightly.
Do they have the same side effects?
In general, yes—because they share the same active ingredient (atorvastatin). Side effects and risks relate to atorvastatin’s pharmacology (for example, muscle-related side effects and liver enzyme changes are class concerns).
Can you switch between Lipitor and generic atorvastatin?
Often, yes, but confirm with your clinician or pharmacist, especially if you have had side effects, are on a specific dosing schedule, or are switching because of cost or availability. Even when active ingredients match, it’s still worth checking that the dose (mg) and instructions are the same.
