Drug & supplement interaction

English Ivy + Pregabalin

Pregabalin brand names: Lyrica, Lyrica CR.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between English Ivy 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

English Ivy 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 English Ivy 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.

English Ivy safety at a glance

English Ivy overall Use caution Standardized leaf-extract products are generally well tolerated, but the raw plant is toxic and can cause poisoning or skin reactions.
Pregnancy Avoid There is not enough reliable safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid use unless directed by your doctor.

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. English Ivy has documented interactions with 3 drug classes — the most serious being cytochrome p450 2c19 (cyp2c19) substrates (moderate), cytochrome p450 2c8 (cyp2c8) substrates (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (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.

What to actually watch for

No Interaction Found — But Data Suggests English Ivy 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.

  • An allergic reaction Worth acting on Additional detail

    Pregabalin

    Listed in the ADVERSE REACTIONS section of the FDA label for Pregabalin. Read the label on DailyMed ›

Reported for English Ivy but not commonly for Pregabalin: a change in taste.

Effects for Pregabalin come from the ADVERSE REACTIONS section of its FDA label; effects for English Ivy come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Pregabalin Is Prescribed For, and What English Ivy 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. English Ivy 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.

English Ivy has been studied for:

  • Neuropathic pain studied, not established English Ivy has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    English Ivy for neuropathic pain

    Although there has been interest in using topical English ivy for neuropathic pain, there is insufficient reliable information about the clinical effects of English ivy for this purpose.

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 English Ivy 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 English Ivy

What is English Ivy?

English Ivy
  • Cough and chest congestion
  • Bronchitis
  • Asthma symptoms
  • Sore throat
  • Skin irritation

English ivy leaf extract is most commonly used in cough and cold syrups to help loosen mucus and ease coughing, and it is a popular ingredient in many European herbal products. Some research suggests it may help with certain coughs, but the evidence is still limited and mixed. The raw plant is poisonous if eaten and can irritate skin, so only use properly prepared commercial products and check with your pharmacist first.

Hedera helix · Araliaceae · Leaves (dried leaf extract) · Syrups, cough drops, oral drops, capsules, tea, topical preparations

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

English Ivy: dosing

There is no single official standardized dose of English ivy for everyone. The right amount depends on the specific product, its strength, and the form (syrup, drops, or capsules).The best approach is to follow the directions on the product label and use only products made for human use.

Taking English Ivy and Pregabalin Together: Common Questions

Is it safe to take English Ivy with Pregabalin?
We do not list a known interaction between English Ivy 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 English Ivy 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 English Ivy 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 English Ivy in each. That is a conversation for your prescriber, especially if Pregabalin is being adjusted to a target.
How was the English Ivy and Pregabalin combination checked?
Interactions in our licensed database are recorded against drug classes. Pregabalin is filed under 3 classifications, and English Ivy has documented interactions with 3 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 English Ivy interact with any other medications?
Yes. English Ivy has 280 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 — English Ivy is not one of them. The Pregabalin interaction page linked on this page lists every one, ranked by severity.
