Drug & supplement interaction

Inositol Nicotinate + Lurasidone

Lurasidone brand name: Latuda.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Inositol Nicotinate and Lurasidone 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 Lurasidone 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

Inositol Nicotinate and Lurasidone

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 Lurasidone and Inositol Nicotinate 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 Lurasidone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lurasidone is filed under 4 classifications — including antipsychotic drugs, seizure threshold lowering drugs, cytochrome p450 3a4 (cyp3a4) substrates. Inositol Nicotinate has documented interactions with 4 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and hmg-coa reductase inhibitors ("statins") (moderate) — and none of Lurasidone’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 Inositol Nicotinate and Lurasidone 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.

  • Diarrhea / Vomiting / Nausea Additional detail

    Inositol Nicotinate

    “Orally, inositol nicotinate is converted to niacin and is therefore likely to cause similar side effects as niacin, including gastrointestinal complaints such as nausea, vomiting, bloating, heartburn, diarrhea, and constipation. These adverse effects from niacin may be reduced by taking it with meals or antacids, and usually disappear within two weeks of continued therapy.”

    Lurasidone

    Listed in the ADVERSE REACTIONS section of the FDA label for Lurasidone. Read the label on DailyMed ›

Reported for Inositol Nicotinate but not commonly for Lurasidone: stomach pain, liver problems, constipation and heartburn.

Effects for Lurasidone come from the ADVERSE REACTIONS section of its FDA label; effects for Inositol Nicotinate come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Lurasidone Products Have a Food Rule — Inositol Nicotinate Should Not Break It

At least one FDA label for a product containing Lurasidone says to take it with food. If you take Inositol Nicotinate on an empty stomach out of habit, keep them separate — and take Lurasidone with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Lurasidone 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.

2 DOSAGE AND ADMINISTRATION LATUDA should be taken with food (at least 350 calories).

From the Dosage and Administration section of the FDA label we read for Lurasidone — 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 Lurasidone Is Prescribed For, and What Inositol Nicotinate Has Been Studied For

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

Lurasidone is prescribed for: Lurasidone hydrochloride tablets are approved to treat schizophrenia in adults and adolescents aged 13 to 17, and to treat depressive episodes associated with bipolar I disorder (bipolar depression) in adults and children aged 10 to 17. Latuda is one of the brand names under which lurasidone is available as a tablet. For bipolar depression, lurasidone can be used on its own (monotherapy) in adults and pediatric patients aged 10 to 17, or used alongside lithium or valproate (adjunctive therapy) in adults.

Inositol Nicotinate has been studied for:

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

    Inositol Nicotinate for schizophrenia

    Although there has been interest in using oral inositol nicotinate for schizophrenia, there is insufficient reliable information about the clinical effects of inositol nicotinate for this purpose.

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 Lurasidone on your own; if you are taking Inositol Nicotinate 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 Lurasidone page

“Supplements deserve real scrutiny alongside lurasidone (Latuda), a medication for schizophrenia and bipolar depression that relies almost entirely on one liver enzyme, CYP3A4, to clear it. Grapefruit blocks that enzyme and can push lurasidone levels high enough to worsen side effects, while St.”

About Inositol Nicotinate

What is Inositol Nicotinate?

Inositol Nicotinate
  • Cholesterol support
  • Improving circulation
  • Raynaud's phenomenon
  • Intermittent claudication (leg pain with walking)
  • A 'no-flush' niacin alternative

Inositol nicotinate is a 'no-flush' form of niacin marketed for cholesterol and circulation. Evidence that it works as well as regular niacin is weak and inconsistent, and it is not a proven replacement for prescription cholesterol treatment. Talk to your pharmacist or doctor before using it, especially if you have liver problems or take other medicines.

Synthetic compound (inositol bound to niacin/nicotinic acid) · Tablets, capsules

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

Inositol Nicotinate: dosing

There is no well-established standard dose for inositol nicotinate, and products vary widely. Do not assume a higher dose is safer or more effective.

Taking Inositol Nicotinate and Lurasidone Together: Common Questions

Is it safe to take Inositol Nicotinate with Lurasidone?
We do not list a known interaction between Inositol Nicotinate and Lurasidone. 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 Inositol Nicotinate and Lurasidone have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Inositol Nicotinate and Lurasidone at the same time of day?
At least one FDA label for a product containing Lurasidone says to take it with food. If you take Inositol Nicotinate on an empty stomach out of habit, keep them separate and take Lurasidone with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Lurasidone products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Inositol Nicotinate and Lurasidone 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 Inositol Nicotinate in each. That is a conversation for your prescriber, especially if Lurasidone is being adjusted to a target.
How was the Inositol Nicotinate and Lurasidone combination checked?
Interactions in our licensed database are recorded against drug classes. Lurasidone is filed under 4 classifications, and Inositol Nicotinate has documented interactions with 4 drug classes — none of Lurasidone'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 Inositol Nicotinate interact with any other medications?
Yes. Inositol Nicotinate has 223 documented drug interactions in our database — Lurasidone 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 Lurasidone interact with any supplements?
Yes. Lurasidone has documented interactions with 149 supplements in our database — Inositol Nicotinate is not one of them. The Lurasidone interaction page linked on this page lists every one, ranked by severity.
