Interaction report

Niacin and Pitavastatin

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

Why Are There 2 Interactions?

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

Moderate

HEPATOTOXIC DRUGS

1 of 2

Why this applies to Pitavastatin

Pitavastatin falls under HEPATOTOXIC DRUGS — the group Niacin interacts with.

Theoretically, concomitant use of niacin and hepatotoxic drugs might increase the risk of hepatotoxicity.
Niacin has been associated with cases of liver toxicity, especially when used in pharmacologic doses. Sustained-release niacin preparations appear to be associated with a higher risk of hepatotoxicity than immediate-release niacin.
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

Here's the simple version: both high-dose niacin and pitavastatin can, on their own, put a little stress on your liver. Put them together and the concern is that the strain might add up, slightly raising the chance of liver irritation. This isn't about niacin changing how pitavastatin works in your blood. It's that two liver-affecting things are being used at once.

Honestly, this is a theoretical worry based on how each one behaves, not proven harm in most people. Everyday food amounts and a standard B3 multivitamin aren't the issue. The risk is tied to high, drug-like niacin doses, especially sustained-release forms. Signs to watch for include unusual tiredness, belly pain, yellowing of the eyes, or dark urine. If you're considering high-dose niacin with your statin, please run it by your pharmacist or doctor first.

HMG-CoA REDUCTASE INHIBITORS ("Statins")

2 of 2

Pitavastatin also falls under HMG-CoA REDUCTASE INHIBITORS ("Statins").

Theoretically, concomitant use of niacin and statins might increase the risk of myopathy and rhabdomyolysis in some patients.
Some case reports have raised concerns that niacin might increase the risk of myopathy and rhabdomyolysis when combined with statins. However, a significantly increased risk of myopathy has not been demonstrated in clinical trials, including those using an FDA-approved combination of lovastatin and niacin (Advicor).
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

Here's the short version: when you pair high-dose niacin with pitavastatin (Zypitamag, Nikita), there's a theoretical concern about muscle problems. Statins on their own can occasionally cause muscle aches, and in rare cases a more serious breakdown of muscle tissue called rhabdomyolysis. A few old case reports suggested adding niacin might nudge that risk up a bit.

The reassuring part is that this hasn't really panned out in actual studies, even ones combining a statin with niacin in one pill. So I'd call this a low-probability, theoretical worry rather than a firm one. The everyday niacin in a multivitamin or your food won't matter at all. If you're taking high-dose niacin, just loop in your pharmacist or doctor, and tell them right away if you get unexplained muscle pain, weakness, or dark urine.

From our pharmacist’s overview on the Pitavastatin page

“Liver strain runs through the serious end of pitavastatin's (Zypitamag, Nikita) supplement interactions, and this list deserves real care rather than a quick skim. The biggest cluster of worrisome entries is herbs and ingredients with their own record of liver injury, and alcohol belongs to that group too, with beer and wine both carry…”

About Niacin

What is Niacin?

Niacin
  • High cholesterol
  • Vitamin B3 deficiency (pellagra)
  • Heart health support
  • General energy and metabolism

Niacin (vitamin B3) is an essential nutrient your body needs for energy and metabolism, and deficiency is uncommon in most developed countries. Prescription-strength niacin has been used to adjust cholesterol levels, but high doses can cause flushing and other side effects and should only be taken under medical supervision. Always talk with a pharmacist or doctor before using high-dose niacin supplements.

About Pitavastatin

What Is Pitavastatin Used For?

Brand names: Zypitamag, Nikita

Pitavastatin tablets are used alongside a cholesterol-lowering diet to reduce LDL-C (low-density lipoprotein, or "bad" cholesterol) in adults with primary hyperlipidemia (high cholesterol not caused by another disease).

Livalo, Pitavastatin Calcium (tablet), and some other pitavastatin tablet products are also approved for adults and children aged 8 years and older with heterozygous familial hypercholesterolemia (HeFH) — an inherited condition that causes very high LDL-C from birth. Zypitamag is labeled only for adults with primary hyperlipidemia; its labeling does not include the pediatric HeFH indication.
