Drug & supplement interaction

Inositol Nicotinate + Indapamide

Indapamide brand names: Lozol, Lozide.

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 Indapamide 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 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 Indapamide

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 Indapamide 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 Indapamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Indapamide is filed under 5 classifications — including thiazide diuretics, diuretic drugs, qt interval-prolonging drugs. 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 Indapamide’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 Indapamide 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.

  • Flushing Additional detail

    “Orally, inositol nicotinate is converted to niacin and is therefore likely to cause similar side effects as niacin. A prostaglandin-mediated flushing reaction is a common adverse effect of oral niacin. A large pooled analysis of clinical studies shows that up to 70% of people may experience flushing with oral niacin.”

Reported for Inositol Nicotinate but not commonly for Indapamide: liver problems, heartburn, bloating or gas and yellowing of the skin or eyes.

Effects for Indapamide come from the ADVERSE REACTIONS section of its FDA label; effects for Inositol Nicotinate come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 17,821 voluntary FDA FAERS reports for Indapamide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Indapamide 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. Indapamide 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.

Indapamide is prescribed for: Indapamide tablets are used to treat high blood pressure (hypertension), either on their own or together with other blood pressure medications. Lowering blood pressure helps reduce the risk of related complications. Indapamide tablets are also used to treat salt and fluid retention (edema) associated with congestive heart failure. In certain cases, indapamide may also be appropriate during pregnancy when swelling is caused by a medical condition rather than normal pregnancy changes — but routine use in otherwise healthy pregnant women is not recommended.

Inositol Nicotinate has been studied for:

  • Hypertension 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 hypertension

    Although there has been interest in using oral inositol nicotinate for hypertension, 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 Indapamide 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.

Everything else you take

See Every Supplement That Interacts With Indapamide

This page covers Inositol Nicotinate only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Indapamide page lists 215 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Arsenic (major) and Cesium (major).

By severity: 13 major · 179 moderate · 23 minor.

From our pharmacist’s overview on the Indapamide page

“A water pill like indapamide (Lozol) lowers blood pressure and pulls potassium down, and most of the 215 supplements and herbs on file press on those same levers. Thirteen entries rate major, so this is a list to read with real care rather than skim.”

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 Indapamide Together: Common Questions

Is it safe to take Inositol Nicotinate with Indapamide?
We do not list a known interaction between Inositol Nicotinate and Indapamide. 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 Indapamide have any of the same side effects?
Yes — our sources link each of them separately to 7 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.
Are Inositol Nicotinate and Indapamide 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 Indapamide is being adjusted to a target.
How was the Inositol Nicotinate and Indapamide combination checked?
Interactions in our licensed database are recorded against drug classes. Indapamide is filed under 5 classifications, and Inositol Nicotinate has documented interactions with 4 drug classes — none of Indapamide'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 — Indapamide 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 Indapamide interact with any supplements?
Yes. Indapamide has documented interactions with 215 supplements in our database — Inositol Nicotinate is not one of them. The Indapamide interaction page linked on this page lists every one, ranked by severity.
