The bottom line No known interaction

We found no known interaction between Puravive and Isoniazid 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.

Puravive and Isoniazid

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 Isoniazid and Puravive 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 Isoniazid

Interactions in our licensed database are recorded against drug classes, not just single drug names. Isoniazid is filed under 8 classifications — including cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors, cytochrome p450 1a2 (cyp1a2) inhibitors. Puravive has documented interactions with 10 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cytochrome p450 2c9 (cyp2c9) substrates (moderate) and qt interval-prolonging drugs (moderate) — and none of Isoniazid’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 Isoniazid’s Own FDA Label Lists

This is not an interaction — none of it involves Puravive. These are the most notable effects listed in the ADVERSE REACTIONS section of Isoniazid’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Memory problems Worth acting on
  • Unsteadiness Worth acting on
  • A severe skin reaction Worth acting on mentioned in 4.6% of FDA reports for Isoniazid
  • Hallucinations Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • High blood sugar Worth acting on
  • Seizures Worth acting on
  • Liver problems Worth acting on mentioned in 5.4% of FDA reports for Isoniazid
  • A low platelet count Worth acting on

Showing the 10 most notable of 21 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Isoniazid. Read the label on DailyMed › Where a percentage is shown, it is the share of 16,103 voluntary FDA FAERS reports for Isoniazid that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Puravive’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Puravive side to compare — that is a limit of the record, not a statement that Puravive has no side effects.

See Every Supplement That Interacts With Isoniazid

This page covers Puravive only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Isoniazid page lists 84 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Siberian Cocklebur (major), Wine (major) and Adrafinil (moderate).

By severity: 4 major · 67 moderate · 13 minor.

From our pharmacist’s overview on the Isoniazid page

“The liver does most of the worrying here. Isoniazid, a backbone of tuberculosis treatment, is already hard on the liver by itself, and 38 of the supplements on this list can add strain, from Siberian cocklebur, a major-rated entry, to everyday herbs like ashwagandha and black cohosh.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Puravive is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Puravive reference on this page ↓

  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Puravive

What is Puravive?

Puravive
  • Weight management
  • Metabolism support
  • Energy levels
  • General wellness
  • Stress and brain health

Puravive is a branded, multi-ingredient capsule marketed mainly for weight loss by claiming to boost brown fat activity, but there is no published, independent clinical research showing the product itself works for this purpose. Some individual ingredients have been studied in laboratory or small human studies, but those results do not prove the finished blend is safe or effective. Talk to a pharmacist or doctor before trying it, especially if you have health conditions or take medications.

Not applicable (multi-ingredient blend) · Capsules

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

Puravive: dosing

There is no established, science-based dose for Puravive, because it is a proprietary blend that has not been tested in published clinical trials. The exact amount of each ingredient may not be fully disclosed.If you choose to try it, follow the directions on the product label and do not take more than the recommended amount. They can help you decide whether it is appropriate for you.

About Isoniazid

What Is Isoniazid Used For?

Brand names: Laniazid, INH, Nydrazid

Isoniazid is used to treat all forms of tuberculosis (TB) caused by susceptible bacteria. Because TB bacteria can quickly become resistant to a single drug, isoniazid must always be combined with other anti-TB medications when treating active TB — it is never used alone for active disease.

Isoniazid is also used as preventive therapy (sometimes called latent TB treatment) for people who have a positive TB skin test but do not yet have active disease. This includes people with HIV infection, close contacts of someone with active TB, recent TB skin test converters, and people with certain medical conditions — such as silicosis, diabetes mellitus, end-stage renal disease, leukemia, or Hodgkin's disease — that raise their TB risk.

Most-Reported Side Effects for Isoniazid

From FAERS, the FDA’s public side-effect reporting system (16,103 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fever 1,102 reports
Nausea 903 reports
Drug-induced liver injury 862 reports
Drug reaction with eosinophilia and systemic symptoms 744 reports
Vomiting 637 reports
