Black Pepper and Ezetimibe, Atorvastatin

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Black Pepper interacts with whole categories of medication. Ezetimibe, Atorvastatin falls into 2 of those categories, so it can interact with Black Pepper in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Ezetimibe, Atorvastatin

Ezetimibe, Atorvastatin falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Black Pepper interacts with.

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Liptruzet combines two cholesterol medicines, and the atorvastatin part is processed by a liver enzyme called CYP3A4. In test-tube studies, piperine (the active compound in black pepper) appears to slow that enzyme down. If that happened in people, more atorvastatin could linger in your body, which in theory could raise the chance of statin side effects like muscle aches, soreness, or, rarely, liver irritation.

The important part: this has only been seen in lab and simulation work, not in actual patients. Black pepper sprinkled on your food is very unlikely to cause a problem. Concentrated piperine supplements (often paired with turmeric) are where I'd be a little more cautious. If you take one regularly, just mention it to your pharmacist or doctor.

ATORVASTATIN (Lipitor)

2 of 2
Theoretically, black pepper might increase blood levels of atorvastatin.
Animal research shows that taking piperine, a constituent of black pepper, 35 mg/kg can increase the maximum serum concentration of atorvastatin three-fold. This has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Your Liptruzet combines two cholesterol medicines, and the part we're focused on here is the atorvastatin. Piperine, the active compound in black pepper, can slow down some of the gut and liver enzymes that normally clear atorvastatin out of your body. In theory, that could let more of the statin build up in your blood.

Here's the honest part: this is based only on animal research, where a concentrated dose of piperine raised atorvastatin levels about threefold. It has not been seen in people, so I wouldn't lose sleep over the pepper on your dinner. If you take a strong piperine supplement (often paired with turmeric), just watch for more statin-type side effects like muscle aches or weakness, and check in with your pharmacist first.

About Black Pepper

What is Black Pepper?

Black Pepper
  • Flavoring and culinary use
  • Digestive complaints like bloating and indigestion
  • Boosting absorption of other supplements
  • Antioxidant and anti-inflammatory support
  • Cold and congestion remedies

Black pepper is a common kitchen spice that is generally safe in the amounts used in food. Its extract, piperine, is mostly added to supplements to help the body absorb other ingredients (like curcumin from turmeric). Strong human evidence for black pepper treating specific health conditions is limited, so use supplement-strength products with care and check with your pharmacist.
