Drug & supplement interaction

Danshen + Pregabalin

Pregabalin brand names: Lyrica, Lyrica CR.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Danshen and Pregabalin 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Danshen and Pregabalin

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 Pregabalin and Danshen 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.

Danshen safety at a glance

Danshen overall Use caution May be used short-term by some adults, but it can affect blood clotting and quality varies between products.

Pregnancy Avoid Not enough safety information; best avoided during pregnancy.

Breastfeeding Avoid Not enough safety information; best avoided while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Pregabalin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pregabalin is filed under 3 classifications — including cns depressants, oral drugs. Danshen has documented interactions with 16 drug classes — the most serious being anticoagulant/antiplatelet drugs (major), digoxin (lanoxin) (major) and amlodipine (norvasc) (moderate) — and none of Pregabalin’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

Danshen Does Interact With Other Medications

What to actually watch for

No Interaction Found — But Data Suggests Danshen and Pregabalin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

Overlapping uses

What Pregabalin Is Prescribed For, and What Danshen Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Pregabalin is a prescription medicine with approved uses on its FDA label. Danshen is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Pregabalin is prescribed for: Pregabalin is used to manage several types of nerve pain, including neuropathic pain from diabetic peripheral neuropathy (nerve damage caused by diabetes) and postherpetic neuralgia (lingering nerve pain after shingles). It is also used to treat fibromyalgia and neuropathic pain associated with spinal cord injury. Lyrica (capsule and oral solution), pregabalin capsules, and pregabalin oral solution are also approved as add-on therapy for partial-onset seizures — Lyrica for patients 1 month and older, and pregabalin capsules for patients 17 years and older. Lyrica CR and pregabalin extended-release tablets are approved only for diabetic peripheral neuropathy pain and postherpetic neuralgia — their effectiveness for fibromyalgia or as seizure add-on therapy has not been established.

Danshen has been studied for:

Diabetes studied, not established Danshen has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Danshen for diabetes

Although there is interest in using oral danshen for diabetes, there is insufficient reliable information about the clinical effects of danshen for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Pregabalin on your own; if you are taking Danshen for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Pregabalin page

“Pregabalin (Lyrica) calms overactive nerves, which is how it eases nerve pain, seizures, and anxiety, and that calming action stacks with almost everything on this list. Of the 95 supplements and herbs, the large majority add their own sedation on top of pregabalin's, and a few can tip that into genuine danger, with deep sedation and s…”

About Danshen

What is Danshen?

Heart and circulation support
Angina (chest pain)
High blood pressure
Anxiety and stress
Liver health

Danshen is a root used in traditional Chinese medicine, mainly for heart and circulation problems. Some early research is promising, but the evidence is not strong enough to confirm it works for any condition, and it may affect blood clotting. Talk to a pharmacist or doctor before using it, especially if you take other medicines or have a health condition.

Salvia miltiorrhiza · Lamiaceae · Root · Capsules, tablets, dried root, teas, tinctures, and injectable forms used in some Asian countries

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

Danshen: dosing

There is no well-established standard dose of Danshen for any condition. Studies have used different forms, strengths, and preparations, which makes it hard to recommend a single dose.If you choose to use a Danshen product, follow the directions on the product label and do not take more than recommended.

Taking Danshen and Pregabalin Together: Common Questions

Is it safe to take Danshen with Pregabalin?

We do not list a known interaction between Danshen and Pregabalin. 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.

Do Danshen and Pregabalin have any of the same side effects?

Yes — our sources link each of them separately to 6 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.

Are Danshen and Pregabalin used for the same thing?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Danshen in each. That is a conversation for your prescriber, especially if Pregabalin is being adjusted to a target.

How was the Danshen and Pregabalin combination checked?

Interactions in our licensed database are recorded against drug classes. Pregabalin is filed under 3 classifications, and Danshen has documented interactions with 16 drug classes — none of Pregabalin'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 Danshen interact with any other medications?

Yes. Danshen has 1,059 documented drug interactions in our database — Pregabalin 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 Pregabalin interact with any supplements?

Yes. Pregabalin has documented interactions with 95 supplements in our database — Danshen is not one of them. The Pregabalin interaction page linked on this page lists every one, ranked by severity.
