Rupturewort and Fentanyl

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 Fentanyl and Rupturewort 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.

Rupturewort safety at a glance

Rupturewort overall Use caution Limited safety data exist, so use carefully and under professional guidance.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Fentanyl’s Own FDA Label Lists

This is not an interaction — none of it involves Rupturewort. These are the most notable effects listed in the ADVERSE REACTIONS section of Fentanyl’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 mentioned in 5.6% of FDA reports for Fentanyl
  • Low magnesium Worth acting on
  • Serotonin syndrome Worth acting on
  • Hearing loss Worth acting on
  • A bowel blockage Worth acting on
  • Bone thinning Worth acting on
  • Pain or burning when passing urine Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • Dehydration Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Fentanyl. Read the label on DailyMed › Where a percentage is shown, it is the share of 114,883 voluntary FDA FAERS reports for Fentanyl that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Rupturewort’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Rupturewort side to compare — that is a limit of the record, not a statement that Rupturewort has no side effects.

From our pharmacist’s overview on the Fentanyl page

“There is very little room for error with fentanyl (Duragesic, Sublimaze, Actiq, and other forms), a powerful opioid where a modest rise in blood level or an extra layer of sedation can become dangerous, so this interaction list deserves real respect. Most of the risk falls into two patterns.”

About Rupturewort

What is Rupturewort?

  • Urinary tract complaints
  • Mild fluid retention (as a diuretic)
  • Kidney and bladder support
  • Wound healing and inflammation (topical, traditional)
  • Spasms or cramping (traditional)

Rupturewort is a traditional European herb mainly used as a mild diuretic and for urinary complaints. Solid human research is very limited, so its true benefits and long-term safety are not well established. Talk to a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Herniaria glabra · Caryophyllaceae · Aerial parts (the above-ground flowering herb) · Tea, dried herb, tincture, capsules

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

Rupturewort: dosing

There is no well-established or standardized dose for rupturewort. Traditional use involves brewing the dried herb as a tea, but reliable dosing guidance from clinical research does not exist.If you choose to use a product, follow the directions on the label and do not exceed them.

About Fentanyl

What Is Fentanyl Used For?

Brand names: Sublimaze, Duragesic, Fentora, Lazanda, Abstral, Subsys

Fentanyl transdermal system is prescribed for severe, persistent pain that cannot be controlled with other pain medicines, including shorter-acting opioids. It is only for people who are already opioid-tolerant — meaning they've been taking a significant daily opioid dose for at least a week.

It is not for short-term pain, post-surgical pain, mild pain, or use on an as-needed basis. Because of serious risks including addiction, overdose, and death, it is reserved for situations where other treatment options have failed or are not appropriate.

Most-Reported Side Effects for Fentanyl

From FAERS, the FDA’s public side-effect reporting system (114,883 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Drug abuse 12,447 reports
Overdose 8,162 reports
Toxicity to various agents 7,374 reports
