The bottom line No known interaction

We found no known interaction between Cassia Auriculata and Penicillamine 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 Penicillamine states a food rule worth keeping to.

Cassia Auriculata and Penicillamine

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 Penicillamine and Cassia Auriculata 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.

Cassia Auriculata safety at a glance

Cassia Auriculata overall Use caution Generally used in traditional diets, but human safety data is limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.

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

How we checked

Why No Interaction Is Listed for Penicillamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Penicillamine is filed under 3 classifications — including nephrotoxic drugs, oral drugs. Cassia Auriculata has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and carbamazepine (tegretol) (moderate) — and none of Penicillamine’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 Penicillamine’s Own FDA Label Lists

This is not an interaction — none of it involves Cassia Auriculata. These are the most notable effects listed in the ADVERSE REACTIONS section of Penicillamine’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.

  • Muscle weakness Worth acting on
  • Bleeding in the gut Worth acting on
  • Low blood sugar Worth acting on
  • Blood clots Worth acting on
  • Pancreatitis Worth acting on
  • Wheezing Worth acting on
  • A severe skin reaction Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia 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 Penicillamine. Read the label on DailyMed › Where a percentage is shown, it is the share of 917 voluntary FDA FAERS reports for Penicillamine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Cassia Auriculata’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cassia Auriculata side to compare — that is a limit of the record, not a statement that Cassia Auriculata has no side effects.

How to take them

Some Penicillamine Products Have a Food Rule — Cassia Auriculata Should Not Break It

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

DOSAGE AND ADMINISTRATION In all patients receiving penicillamine, it is important that CUPRIMINE be given on an empty stomach, at least one hour before meals or two hours after meals, and at least one hour apart from any other drug, food, or milk.

From the Dosage and Administration section of the FDA label we read for Penicillamine — 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 Cassia Auriculata

What is Cassia Auriculata?

  • Blood sugar support
  • Skin health
  • Urinary complaints
  • Digestive upset
  • General tonic and antioxidant

Cassia auriculata (often called Tanner's cassia or Avaram) is a flowering shrub used in traditional Indian medicine, especially for blood sugar and skin concerns. Most evidence comes from laboratory and animal studies, so its benefits in people are not well proven. Talk to your pharmacist or doctor before using it, particularly if you take diabetes medicine or are pregnant.

Senna auriculata · Fabaceae · Flowers, leaves, bark, seeds, and roots · Tea, powder (churna), capsules, and traditional decoctions

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

Cassia Auriculata: dosing

There is no well-established, standardized dose for Cassia auriculata. Traditional use has varied widely depending on the part of the plant and the preparation, such as a tea made from dried flowers or a powder.Because supplements differ in strength, the best advice is to follow the directions on the product label and not exceed the recommended amount.

About Penicillamine

What Is Penicillamine Used For?

Brand names: Cuprimine, Depen Titratable

Penicillamine is used for three distinct conditions. It treats Wilson's disease — a rare genetic disorder in which the body accumulates dangerous levels of copper — by binding to the excess copper and helping the body remove it. It also treats cystinuria, a condition where the amino acid cystine builds up and forms painful kidney stones, by converting cystine into a more soluble form that the body can excrete more easily.

For patients with severe, active rheumatoid arthritis who have not responded adequately to conventional therapies, penicillamine (available as Aagylur, Cuprimine, Depen, and other products) may be used to help suppress disease activity and reduce joint pain, tenderness, and swelling.

Taking Cassia Auriculata and Penicillamine Together: Common Questions

Is it safe to take Cassia Auriculata with Penicillamine?
We do not list a known interaction between Cassia Auriculata and Penicillamine. 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 Cassia Auriculata and Penicillamine at the same time of day?
At least one FDA label for a product containing Penicillamine 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 Penicillamine on its own and move Cassia Auriculata 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 Cassia Auriculata and Penicillamine combination checked?
Interactions in our licensed database are recorded against drug classes. Penicillamine is filed under 3 classifications, and Cassia Auriculata has documented interactions with 2 drug classes — none of Penicillamine'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 Cassia Auriculata interact with any other medications?
Yes. Cassia Auriculata has 87 documented drug interactions in our database — Penicillamine 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 Penicillamine interact with any supplements?
Yes. Penicillamine has documented interactions with 26 supplements in our database — Cassia Auriculata is not one of them. The Penicillamine interaction page linked on this page lists every one, ranked by severity.
