Drug & supplement interaction

Garcinia + 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 Garcinia 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

Garcinia 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 Garcinia 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.

Garcinia safety at a glance

Garcinia overall Use caution Generally tolerated short-term, but rare reports of liver injury warrant caution.
Pregnancy Avoid Not enough safety data; avoid use during pregnancy.
Breastfeeding Avoid Not enough safety data; avoid use 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. Garcinia has documented interactions with 4 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and hepatotoxic drugs (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

Garcinia has 704 moderate known drug interactions in our database — Pregabalin isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

No Interaction Found — But Data Suggests Garcinia 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. 8 of them are worth acting on rather than waiting out — marked below.

  • Severe muscle breakdown Worth acting on Additional detail

    Garcinia

    “Orally, garcinia-containing products have been associated with rhabdomyolysis. There is a case report of a patient who developed rhabdomyolysis 3 hours after ingestion of an herbal product containing ephedra, guarana, chitosan, gymnema, garcinia, and chromium. Since there were multiple ingredients, the effect cannot be conclusively attributed to garcinia.”

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 Garcinia

What is Garcinia?

Garcinia
  • Weight loss
  • Appetite suppression
  • Curbing sugar and carb cravings
  • Supporting metabolism
  • Traditional cooking and souring agent

Garcinia is a tropical fruit whose rind contains hydroxycitric acid (HCA), widely marketed for weight loss and appetite control. The scientific evidence is weak and mixed, with most studies showing only small or no meaningful weight effects, and rare reports of liver problems raise safety concerns. Talk to a pharmacist or doctor before trying it, especially if you have liver issues, are pregnant, or are breastfeeding.

Garcinia gummi-gutta · Clusiaceae · Fruit rind (pericarp) · Capsules, tablets, powders, gummies, and liquid extracts (often standardized to a percentage of HCA)

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

Garcinia: dosing

There is no well-established, proven dose for Garcinia. Products vary widely in their strength and in how much HCA they contain, which makes it hard to compare one product to another.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount.

About Pregabalin

What Is Pregabalin Used For?

Brand names: Lyrica, Lyrica CR

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.

Most-Reported Side Effects for Pregabalin

From FAERS, the FDA’s public side-effect reporting system (270,557 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Garcinia and Pregabalin Together: Common Questions

Is it safe to take Garcinia with Pregabalin?
We do not list a known interaction between Garcinia 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 Garcinia 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.
How was the Garcinia and Pregabalin combination checked?
Interactions in our licensed database are recorded against drug classes. Pregabalin is filed under 3 classifications, and Garcinia has documented interactions with 4 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 Garcinia interact with any other medications?
Yes. Garcinia has 704 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 — Garcinia is not one of them. The Pregabalin interaction page linked on this page lists every one, ranked by severity.
