Drug & supplement interaction

Cabbage + Niacin (prescription drug)

Niacin (prescription drug) brand names: Niaspan, Niacor.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Cabbage and Niacin (prescription drug) in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Niacin (prescription drug) states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Cabbage and Niacin (prescription drug)

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Niacin (prescription drug) and Cabbage in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Niacin (prescription drug)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Niacin (prescription drug) is filed under 3 classifications — including hepatotoxic drugs, oral drugs. Cabbage has documented interactions with 6 drug classes — the most serious being acetaminophen (tylenol, others) (moderate), antidiabetes drugs (moderate) and cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Niacin (prescription drug)’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Cabbage and Niacin (prescription drug) May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Itching Additional detail

    Cabbage

    “Some preliminary clinical research shows that application of cabbage leaf wraps to knee joints for at least 2 hours daily for 4 weeks is generally well-tolerated. Of the 27 patients using cabbage leaf wraps in this study, one patient reported an itching and burning sensation during the application. This patient was later found to have shingles, which may explain the adverse event.”

    Cabbage

    “Topically, cabbage may cause contact dermatitis. Allergic reactions to cabbage-related vegetables are rare. However, anaphylactic reactions to broccoli and cauliflower have been reported. Because the surface proteins believed to cause allergic reactions to brocolli are also found in cabbage, some patients allergic to brocolli or other vegetables in the Brassicaceae family may also be allergic to cabbage.”

How to take them

Some Niacin (prescription drug) Products Have a Food Rule — Cabbage Should Not Break It

At least one FDA label for a product containing Niacin (prescription drug) says to take it on an empty stomach. Most supplements — Cabbage included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Niacin (prescription drug) on its own and move Cabbage to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Niacin (prescription drug) products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Flushing, pruritus, and gastrointestinal distress are also greatly reduced by slowly increasing the dose of niacin and avoiding administration on an empty stomach.

From the Dosage and Administration section of the FDA label we read for Niacin (prescription drug) — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Overlapping uses

What Niacin (prescription drug) Is Prescribed For, and What Cabbage Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Niacin (prescription drug) is a prescription medicine with approved uses on its FDA label. Cabbage is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Niacin (prescription drug) is prescribed for: Niacin is used alongside diet changes to lower high LDL (bad) cholesterol and triglycerides, and to raise HDL (good) cholesterol in adults with primary hyperlipidemia (high cholesterol) or mixed dyslipidemia (abnormal levels of several blood fats). It is also used to treat adults with very high triglyceride levels who are at risk of pancreatitis (dangerous inflammation of the pancreas) when diet alone hasn't worked. Niacin extended-release tablets are additionally indicated to reduce the risk of a repeat nonfatal heart attack in patients who have already had a heart attack and also have high cholesterol. When used together with a bile acid binding resin, niacin extended-release tablets can slow or even reverse the buildup of plaque in the arteries (atherosclerosis) in patients with coronary artery disease and high cholesterol.

  • Hyperlipidemia studied, not established Cabbage has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Cabbage for hyperlipidemia

    It is unclear if oral cabbage is beneficial in patients with hyperlipidemia.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Niacin (prescription drug) on your own; if you are taking Cabbage for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Niacin (prescription drug) page

“Prescription niacin (Niaspan, Niacor) is dosed high enough for cholesterol treatment that it can strain the liver all by itself, so this is a list to treat seriously rather than skim. Thirty-eight of the 60 interacting supplements and herbs can add their own liver stress, and alcohol leads that group, with beer and wine accounting for…”

About Cabbage

What is Cabbage?

Cabbage
  • Breast engorgement during breastfeeding
  • Joint pain and swelling (topical)
  • Digestive and stomach upset
  • General nutrition and antioxidant support
  • Skin and minor inflammation (topical)

Cabbage is a nutritious, low-calorie vegetable that is safe to eat as food and is sometimes applied to the skin as a leaf wrap for breast engorgement or sore joints. Most medicinal claims are based on tradition or limited research, with the strongest (though still modest) evidence being for cooling cabbage leaves on engorged breasts. Talk to your pharmacist or doctor before using cabbage in large amounts or as a treatment.

Brassica oleracea · Brassicaceae (Cruciferae) · Leaves (head); also juice and extracts · Fresh vegetable, raw leaves, juice, fermented (sauerkraut), capsules, and topical leaf wraps

An interaction check asks whether these two react with each other — it does not ask whether Cabbage is a good idea for someone in your situation. Here is what our Cabbage record says about it on its own.

Cabbage: dosing

There is no standardized medicinal dose for cabbage. As a food, it can be eaten freely as part of a balanced diet.For breast engorgement, a common traditional approach is to apply clean, chilled cabbage leaves to the breasts for a limited time and remove them once they wilt or symptoms ease. For supplements or juice, follow the product label.

Taking Cabbage and Niacin (prescription drug) Together: Common Questions

Is it safe to take Cabbage with Niacin (prescription drug)?
We do not list a known interaction between Cabbage and Niacin (prescription drug). That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Cabbage and Niacin (prescription drug) have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Cabbage and Niacin (prescription drug) at the same time of day?
At least one FDA label for a product containing Niacin (prescription drug) says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Niacin (prescription drug) on its own and move Cabbage to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Are Cabbage and Niacin (prescription drug) used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Cabbage in each. That is a conversation for your prescriber, especially if Niacin (prescription drug) is being adjusted to a target.
How was the Cabbage and Niacin (prescription drug) combination checked?
Interactions in our licensed database are recorded against drug classes. Niacin (prescription drug) is filed under 3 classifications, and Cabbage has documented interactions with 6 drug classes — none of Niacin (prescription drug)'s classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Cabbage interact with any other medications?
Yes. Cabbage has 325 documented drug interactions in our database — Niacin (prescription drug) is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Niacin (prescription drug) interact with any supplements?
Yes. Niacin (prescription drug) has documented interactions with 60 supplements in our database — Cabbage is not one of them. The Niacin (prescription drug) interaction page linked on this page lists every one, ranked by severity.
