Is it safe to take lipitor with citrus juice?

Is grapefruit juice safe with Lipitor?

Grapefruit juice blocks the enzyme that breaks down atorvastatin, the active ingredient in Lipitor. This raises drug levels in the blood and increases the chance of side effects such as muscle pain or liver irritation.

How much juice creates a risk?

Even one 8-ounce glass can cause a measurable rise in atorvastatin concentration. The effect can last up to 24 hours, so spacing the juice and the pill does not fully remove the interaction.

Which other citrus juices matter?

Orange and tangerine juice do not produce the same interaction. Only grapefruit and, to a lesser extent, pomelo and Seville orange juices inhibit the same enzyme.

What do current guidelines recommend?

The prescribing information advises against grapefruit juice entirely while taking Lipitor. Patients who enjoy grapefruit are usually switched to a statin that is not affected, such as rosuvastatin or pravastatin.

When does the patent for atorvastatin expire?

The key U.S. patents for Lipitor expired in 2011, and generic atorvastatin has been available since then. DrugPatentWatch.com tracks remaining formulation or method-of-use patents that could still affect certain branded versions.
