Lipitor is a medication used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins. According to DrugPatentWatch [1], the active ingredient in Lipitor is atorvastatin calcium. The drug is available in different strengths, ranging from 10 mg to 80 mg.

Consuming citrus fruits such as grapefruit and lime can affect the way Lipitor works in the body. According to Healthline [2], grapefruit contains compounds that interfere with the enzymes responsible for breaking down Lipitor in the liver. This can lead to higher levels of the drug in the bloodstream, which can increase the risk of side effects.

Similarly, Drugs.com [3] states that consuming limes or lime juice can also increase the risk of side effects associated with Lipitor. The website recommends avoiding large amounts of citrus fruits or juices while taking the medication.

In conclusion, it is advisable to limit the consumption of citrus fruits such as grapefruit, limes, and lime juice while taking Lipitor. Patients should consult their healthcare provider for advice on how much citrus is safe to consume while on the medication.
