Drug & supplement interaction

Cassava + Pregabalin

Pregabalin brand names: Lyrica, Lyrica CR.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Cassava 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.

Cassava 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 Cassava 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 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. Cassava has documented interactions with 1 drug class — the most serious being thyroid hormone (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

No Interaction Found — But Data Suggests Cassava 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. 6 of them are worth acting on rather than waiting out — marked below.

  • Loss of vision Worth acting on Additional detail

    Cassava

    “Orally, long-term consumption of wild or unprocessed cassava has been associated with the development of optic neuropathy and tropical ataxic neuropathy, presenting as loss of vision and hearing, particularly in protein-malnourished populations. Both of these conditions are attributed to cassava-induced cyanide overload.”

Special populations

Cassava in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally as a food, especially in large quantities. Animal research suggests that consuming milled cassava powder as 80% of the diet during the first 15 days of pregnancy can cause teratogenic effects, including intrauterine growth restriction, limb defects, and abnormally small brain (microencephaly). Also, epidemiological evidence suggests that pregnant women who regularly consume dietary cassava in the form of gari during pregnancy have higher levels of thiocyanate, which has negative effects on fetal birthweight, compared to those who do not consume cassava. ...when applied intravaginally. Inserting 2-3 cm of cassava stalk into the vagina has been used to induce abortion and labor.

Lactation Possibly Unsafe

When used orally in food amounts, especially in large quantities. Excess consumption of cassava during lactation may increase the risk of exposing the infant to thiocyanate, which can negatively affect thyroid function in the infant.

Overlapping uses

What Pregabalin Is Prescribed For, and What Cassava 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. Cassava 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.

Cassava has been studied for:

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

    Cassava for diabetes

    Observational research suggests that higher dietary intake of cassava flour is linked with a 9% reduced risk for developing type 2 diabetes when compared with lower dietary intake.

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 Cassava for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Cassava

What is Cassava?

Cassava
  • Dietary staple/source of carbohydrates
  • Fertility aid (to conceive twins)
  • Digestive support
  • General energy
  • Gluten-free flour alternative

Cassava is a starchy root vegetable that feeds millions of people worldwide, but it must be properly cooked or processed because the raw plant contains compounds that release cyanide. As a supplement, it is marketed for fertility and twin conception, but there is no good scientific evidence to support these claims. Always prepare cassava correctly and talk to your pharmacist or doctor before using cassava products for health reasons.

Manihot esculenta · Euphorbiaceae · Starchy root (tuber) and leaves · Whole root, flour, tapioca, dried powder, capsules

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

Cassava: dosing

There is no established or standardized dose for cassava as a supplement. As a food, it is simply prepared and eaten in normal serving sizes after proper cooking.For cassava supplements or flour products, follow the directions on the product label.

Taking Cassava and Pregabalin Together: Common Questions

Is it safe to take Cassava with Pregabalin?
We do not list a known interaction between Cassava 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 Cassava and Pregabalin have any of the same side effects?
Yes — our sources link each of them separately to 10 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 Cassava 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 Cassava in each. That is a conversation for your prescriber, especially if Pregabalin is being adjusted to a target.
How was the Cassava and Pregabalin combination checked?
Interactions in our licensed database are recorded against drug classes. Pregabalin is filed under 3 classifications, and Cassava has documented interactions with 1 drug class — 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 Cassava interact with any other medications?
Yes. Cassava has 16 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 — Cassava is not one of them. The Pregabalin interaction page linked on this page lists every one, ranked by severity.
