Coffee Charcoal and Bempedoic Acid

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ORAL DRUGS

Why this applies to Bempedoic Acid

Bempedoic Acid falls under ORAL DRUGS — the group Coffee Charcoal interacts with.

Coffee charcoal can reduce the absorption of orally administered drugs and should be separated from oral drug administration by at least two hours.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the simple version: coffee charcoal acts like a sponge in your gut. Because it has that porous, charcoal-like surface, it can grab onto medications you swallow and keep some of them from being absorbed. If you take your Nexletol (bempedoic acid) too close to a dose of coffee charcoal, less of the drug may make it into your bloodstream, which could mean it doesn't lower your LDL ('bad') cholesterol as well as it should.

The good news is this is easy to manage. Spacing them apart by at least two hours usually keeps the charcoal from interfering. Keep in mind this concern comes from how charcoal behaves in general, not from a study on this exact pairing, so it's a precaution rather than a known problem. Before combining them, check with your pharmacist or doctor.

From our pharmacist’s overview on the Bempedoic Acid page

“Activated charcoal is the ingredient I would rule out entirely on bempedoic acid (Nexletol), a daily tablet for lowering LDL cholesterol. It carries the only major rating of the 21 ingredients on file because it can trap the drug in the gut and shrink the dose your body absorbs.”

About Coffee Charcoal

What is Coffee Charcoal?

  • Diarrhea
  • Inflammatory bowel conditions
  • Irritable bowel syndrome (IBS)
  • Mild digestive upset
  • Wound and skin care (topical, traditional)

Coffee charcoal is made by roasting green coffee beans until they turn black, creating a charcoal-like material used traditionally for diarrhea and digestive complaints. Scientific evidence supporting its benefits is very limited, and it should not replace proven treatments. Talk with your pharmacist or doctor before using it, especially if you have a chronic gut condition.

About Bempedoic Acid

What Is Bempedoic Acid Used For?

Brand name: Nexletol

Nexletol (bempedoic acid) is used in adults to reduce the risk of major cardiovascular events — including cardiovascular death, heart attack, stroke, and procedures to open blocked arteries — in people at increased cardiovascular risk who are unable to take recommended statin therapy.

Nexletol is also used alongside diet and exercise to lower LDL cholesterol in adults with high cholesterol (hypercholesterolemia), including a genetic form called heterozygous familial hypercholesterolemia (HeFH). It can be used with other cholesterol-lowering medicines or alone when combining with another therapy isn't possible.
