Teazle and Naltrexone Hydrochloride

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 Naltrexone Hydrochloride and Teazle 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.

Teazle safety at a glance

Teazle overall Not established Human safety data are very limited, so its safety profile is not well established.

How we checked

Why No Interaction Is Listed for Naltrexone Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Naltrexone Hydrochloride is filed under 3 classifications — including hepatotoxic drugs, oral drugs. Teazle has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (moderate) and cholinergic drugs (moderate) — and none of Naltrexone Hydrochloride’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 Naltrexone Hydrochloride’s Own FDA Label Lists

This is not an interaction — none of it involves Teazle. These are the most notable effects listed in the ADVERSE REACTIONS section of Naltrexone Hydrochloride’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.

  • Dependence or withdrawal symptoms Worth acting on
  • A stroke or mini-stroke Worth acting on
  • A bowel blockage Worth acting on
  • Dehydration Worth acting on
  • A heart attack Worth acting on
  • Blood clots Worth acting on
  • Pancreatitis Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on

Showing the 10 most notable of 62 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 Naltrexone Hydrochloride. Read the label on DailyMed › Where a percentage is shown, it is the share of 9,867 voluntary FDA FAERS reports for Naltrexone Hydrochloride that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Teazle’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Teazle side to compare — that is a limit of the record, not a statement that Teazle has no side effects.

About Teazle

What is Teazle?

Teazle
  • Lyme disease (folk use)
  • Joint and muscle pain
  • Osteoarthritis and rheumatoid arthritis
  • Skin conditions such as psoriasis
  • Wound healing

Teazle (Dipsacus fullonum) is a spiky plant used in traditional and folk medicine, most notably as a tincture marketed for Lyme disease and for joint pain and skin problems. There is very little high-quality human research to support any of these uses, so its benefits remain unproven. Talk with a pharmacist or doctor before trying it, and never use it to replace standard treatment for serious infections like Lyme disease.

Dipsacus fullonum · Caprifoliaceae · Root, leaves, and aerial parts · Tincture, tea, capsules, dried root, topical preparations

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

Teazle: dosing

There is no established or standardized dose for teazle. Dosing in folk traditions varies widely, and products such as tinctures and capsules differ in strength.If you choose to try a teazle product, follow the directions on the label and do not exceed them.

About Naltrexone

What Is Naltrexone Used For?

Brand name: Revia

Naltrexone Hydrochloride tablets are used to treat alcohol dependence and to block the effects of opioids in people being treated for opioid dependence. It works best as part of a full treatment program that includes counseling and support.

The extended-release injectable suspension (brand name Vivitrol) is used to treat alcohol dependence in patients who are already not drinking before starting treatment, and to prevent relapse to opioid dependence after a patient has completed opioid detoxification. Vivitrol must always be part of a comprehensive treatment program that includes psychosocial support.
