What impact does lipitor have on dairy intake?

How does Lipitor interact with dairy foods?

Lipitor, known generically as atorvastatin, belongs to the class of drugs called statins. These medications work by blocking an enzyme in the liver that produces cholesterol. They take effect after being absorbed through the gastrointestinal tract.

Does dairy affect how well Lipitor works?

Dairy foods themselves do not interfere with the absorption or effectiveness of Lipitor.

Patients can take their dose with or without food, according to the official prescribing information.

What happens if a patient takes Lipitor with dairy?

Are there any side effects tied to dairy consumption while on Lipitor?
