The bottom line No known interaction

We found no known interaction between Teazle and Deferasirox 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 label for Deferasirox states a food rule worth keeping to.

Teazle and Deferasirox

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 Deferasirox 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.
Pregnancy Avoid There is not enough safety information, so it is best to avoid use during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid use to be cautious.

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

How we checked

Why No Interaction Is Listed for Deferasirox

Interactions in our licensed database are recorded against drug classes, not just single drug names. Deferasirox is filed under 5 classifications — including cytochrome p450 3a4 (cyp3a4) inducers, cytochrome p450 1a2 (cyp1a2) inhibitors, glucuronidated drugs. Teazle has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (moderate) and cholinergic drugs (moderate) — and none of Deferasirox’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 Deferasirox’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 Deferasirox’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.

  • Hearing loss Worth acting on
  • Anemia Worth acting on mentioned in 12.2% of FDA reports for Deferasirox
  • Bleeding in the gut Worth acting on
  • Low potassium Worth acting on
  • Pancreatitis Worth acting on
  • A severe skin reaction Worth acting on
  • Kidney problems Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Liver problems Worth acting on

Showing the 10 most notable of 26 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 Deferasirox. Read the label on DailyMed › Where a percentage is shown, it is the share of 26,369 voluntary FDA FAERS reports for Deferasirox 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.

How to take them

Some Deferasirox Products Have a Food Rule — Teazle Should Not Break It

At least one FDA label for a product containing Deferasirox says to take it on an empty stomach. Most supplements — Teazle included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Deferasirox on its own and move Teazle to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Deferasirox products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Take JADENU tablets on an empty stomach or with a light meal (contains less than 7% fat content and approximately 250 calories).

From the Dosage and Administration section of the FDA label we read for Deferasirox — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

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 Deferasirox

What Is Deferasirox Used For?

Brand names: Exjade, Jadenu

Deferasirox — available as tablets (including Exjade and Jadenu) and oral powder granules (including Jadenu) — is used to treat chronic iron overload in patients 2 years and older whose bodies have accumulated too much iron from repeated blood transfusions.

It is also used to treat chronic iron overload in patients 10 years and older who have non-transfusion-dependent thalassemia (NTDT) syndromes — a group of inherited blood disorders — when liver iron levels and blood ferritin levels meet specific thresholds. The safety and effectiveness of deferasirox when combined with other iron-chelation therapies have not been established.

Most-Reported Side Effects for Deferasirox

From FAERS, the FDA’s public side-effect reporting system (26,369 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 2,343 reports
Sickle cell anaemia with crisis 1,813 reports
Fever 1,474 reports

Taking Teazle and Deferasirox Together: Common Questions

Is it safe to take Teazle with Deferasirox?
We do not list a known interaction between Teazle and Deferasirox. 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.
Should I take Teazle and Deferasirox at the same time of day?
At least one FDA label for a product containing Deferasirox says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Deferasirox on its own and move Teazle to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Teazle and Deferasirox combination checked?
Interactions in our licensed database are recorded against drug classes. Deferasirox is filed under 5 classifications, and Teazle has documented interactions with 2 drug classes — none of Deferasirox'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 Teazle interact with any other medications?
Yes. Teazle has 219 documented drug interactions in our database — Deferasirox 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 Deferasirox interact with any supplements?
