The bottom line No known interaction

We found no known interaction between Goldthread and Levetiracetam 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.

Goldthread and Levetiracetam

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 Levetiracetam and Goldthread 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 Levetiracetam

Interactions in our licensed database are recorded against drug classes, not just single drug names. Levetiracetam is filed under 3 classifications — anticonvulsants, cns depressants, oral drugs. Goldthread has documented interactions with 2 drug classes — the most serious being cyclosporine (neoral, sandimmune) (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Levetiracetam’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.

Keep it in perspective

This is not an interaction — none of it involves Goldthread. These are the most notable effects listed in the ADVERSE REACTIONS section of Levetiracetam’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. 8 of them are worth acting on rather than waiting out — marked below.

  • Memory problems Worth acting on
  • Unsteadiness Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • Low mood Worth acting on
  • A severe allergic reaction Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Mood changes or irritability

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

Special populations

Goldthread in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

When used orally. Berberine is thought to cross the placenta and may cause harm to the fetus. Kernicterus has developed in newborn infants exposed to berberine. Preliminary evidence suggests that maternal intake of goldthread during the first trimester increases the risk of congenital malformations of the central nervous system.

Lactation Likely Unsafe

When used orally. Berberine and other harmful constituents can be transferred to the infant through breast milk.

About Goldthread

What is Goldthread?

Goldthread
  • Digestive upset and diarrhea
  • Mouth sores and sore throat
  • Inflammation
  • Antimicrobial (fighting germs)
  • Blood sugar support
  • Skin and eye complaints

Goldthread is a traditional Chinese and East Asian herb whose root is rich in berberine, a compound being studied for blood sugar, cholesterol, and antimicrobial effects. Strong human evidence for goldthread itself is limited, and it should be avoided in pregnancy and breastfeeding. Talk with your pharmacist or doctor before using it, especially if you take other medicines.

Coptis chinensis · Ranunculaceae · Root and rhizome (the underground stem) · Dried root, powder, capsules, tinctures, teas, and topical preparations

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

Goldthread: dosing

There is no well-established standard dose for goldthread. Products differ widely in how they are made and how much active compound they contain, so it is hard to recommend a single safe amount.The best approach is to follow the directions on the product label and not exceed them.

About Levetiracetam

What Is Levetiracetam Used For?

Brand names: Keppra, Elepsia XR, Spritam

Levetiracetam is used to treat several types of seizures. It treats partial-onset seizures (seizures that start in one area of the brain) and is used as add-on therapy for myoclonic seizures (sudden, brief muscle jerks) in people with juvenile myoclonic epilepsy aged 12 and older, and for primary generalized tonic-clonic seizures (grand mal seizures) in people with idiopathic generalized epilepsy aged 6 and older.

Age eligibility varies by product. Keppra oral and Roweepra tablets treat partial-onset seizures in patients as young as 1 month. Spritam and levetiracetam tablets for oral suspension treat partial-onset seizures in patients 4 years and older weighing more than 20 kg. Extended-release products — including Elepsia XR, Keppra XR, and Levetiracetam ER — are approved only for partial-onset seizures in patients 12 years and older. Injectable forms are used intravenously when a patient temporarily cannot take oral medication.
