Hercules Club and Methadone

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 Methadone and Hercules Club 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 Methadone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Methadone is filed under 11 classifications — including narcotic drugs, cytochrome p450 2d6 (cyp2d6) inhibitors, serotonergic drugs. Hercules Club has documented interactions with 3 drug classes — the most serious being antacids (minor), h2-blockers (minor) and proton pump inhibitors (ppis) (minor) — and none of Methadone’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 Methadone’s Own FDA Label Lists

This is not an interaction — none of it involves Hercules Club. These are the most notable effects listed in the ADVERSE REACTIONS section of Methadone’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.

  • Low magnesium Worth acting on
  • Dependence or withdrawal symptoms Worth acting on
  • Serotonin syndrome Worth acting on
  • Trouble passing urine Worth acting on
  • Low blood sugar Worth acting on
  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • Hallucinations Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Methadone. Read the label on DailyMed › Hercules Club’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Hercules Club side to compare — that is a limit of the record, not a statement that Hercules Club has no side effects.

About Hercules Club

What is Hercules Club?

Hercules Club
  • Toothache and mouth pain
  • Indigestion and sluggish digestion
  • Rheumatism and joint pain
  • Circulation (as a stimulant or tonic)
  • Sore throat

Hercules Club (southern prickly ash) is a traditional folk remedy used mainly for toothache, digestion, and joint pain, often by chewing the bark, which causes a tingling, numbing feeling in the mouth. Modern scientific evidence supporting these uses is very limited, and safety has not been well studied, so it is best to talk with a pharmacist or doctor before using it.

Zanthoxylum clava-herculis · Rutaceae · Bark, roots, and berries · Dried bark, tinctures, teas, and topical preparations

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

Hercules Club: dosing

There is no established standardized dose for Hercules Club. Traditional use varied widely, and product strengths differ from one brand to another.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Methadone

What Is Methadone Used For?

Brand name: Dolophine

Methadone treats severe and persistent pain that requires daily, around-the-clock, long-term opioid treatment and cannot be managed adequately with other options. It is available in several forms for this use, including oral solution, oral tablets, oral concentrate, and injectable forms (intravenous, intramuscular, and subcutaneous). Injectable methadone is not approved for outpatient pain treatment — it is reserved for hospitalized patients unable to take oral medication.

Methadone is also used for the detoxification and maintenance treatment of opioid addiction (dependence on heroin or other morphine-like drugs). Oral forms — including tablets, dispersible tablets (such as Methadose Dispersible and DISKETS), and oral concentrates (such as Methadone Hydrochloride Intensol™, Methadose, and others) — are approved for this use. By law, methadone for opioid addiction treatment must be dispensed only by certified opioid treatment programs. Injectable methadone is not approved for outpatient addiction treatment.
