Drug & supplement interaction

Asafoetida + Gabapentin

Gabapentin brand names: Neurontin, Gralise.

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 Asafoetida and Gabapentin 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

Asafoetida and Gabapentin

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 Gabapentin and Asafoetida 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 Gabapentin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Gabapentin is filed under 4 classifications — including anticonvulsants, cns depressants, oral drugs. Asafoetida has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antihypertensive drugs (moderate) — and none of Gabapentin’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 Asafoetida and Gabapentin 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.

  • Seizures Worth acting on Additional detail

    Asafoetida

    “Orally, asafoetida appears to be generally well tolerated. Large amounts of asafoetida have been reported to cause swelling of the lips, belching, flatulence, diarrhea, headache, or convulsions (18). There are reports of infantile methemoglobinemia associated with asafoetida (4,102549). Topically, asafoetida has been reported to cause genital organ swelling (18).”

Where a percentage is shown, it is the share of 361,481 voluntary FDA FAERS reports for Gabapentin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

From our pharmacist’s overview on the Gabapentin page

“Gabapentin (Neurontin, Gralise) calms overactive nerves, which means it already slows your nervous system down, and that is exactly what 78 of the 106 supplements on this list also do. So the dominant risk here is sedation stacked on sedation, extra drowsiness at best and dangerously slowed breathing at worst, and with seven entries ra…”

About Asafoetida

What is Asafoetida?

Asafoetida
  • Digestive upset and gas
  • Bloating and stomach cramps
  • Irritable bowel symptoms
  • Respiratory complaints
  • Used as a cooking spice

Asafoetida is a strong-smelling plant resin used widely as a spice and in traditional medicine, mainly for digestive complaints. Solid human evidence for its medicinal benefits is limited, though it is generally considered safe in the small amounts used in cooking. Talk with your pharmacist or doctor before using concentrated supplements, and avoid them during pregnancy and breastfeeding.

Ferula assa-foetida · Apiaceae · Dried gum resin (oleo-gum-resin) from the root and rhizome · Powder, capsules, resin, tincture/extract, culinary spice

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

Asafoetida: dosing

There is no official, standardized medicinal dose for asafoetida. The amount used can vary widely between products and traditional recipes, and high-quality dosing studies in people are lacking.As a cooking spice, only a small pinch of powder is typically used.

About Gabapentin

What Is Gabapentin Used For?

Brand names: Neurontin, Gralise

Gabapentin (brands include Neurontin, Relgaabi, Gabarone, Gralise, and Horizant) is primarily used to manage postherpetic neuralgia (PHN) — the nerve pain that lingers after a shingles outbreak — in adults. Neurontin, Relgaabi, Gabarone, and gabapentin capsules, tablets, and oral solution are also used as add-on therapy for partial onset seizures (a type of epilepsy) in adults and children aged 3 and older.

Horizant (gabapentin enacarbil extended-release tablet) has two specific approvals: treatment of moderate-to-severe primary restless legs syndrome (RLS) in adults, and management of postherpetic neuralgia in adults. Horizant is not recommended for people who need to sleep during the day and stay awake at night. Gralise is approved only for postherpetic neuralgia and cannot be substituted for other gabapentin products due to its different release profile.

Most-Reported Side Effects for Gabapentin

From FAERS, the FDA’s public side-effect reporting system (361,481 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 22,728 reports

Taking Asafoetida and Gabapentin Together: Common Questions

Is it safe to take Asafoetida with Gabapentin?
We do not list a known interaction between Asafoetida and Gabapentin. 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 Asafoetida and Gabapentin have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Asafoetida and Gabapentin combination checked?
Interactions in our licensed database are recorded against drug classes. Gabapentin is filed under 4 classifications, and Asafoetida has documented interactions with 2 drug classes — none of Gabapentin'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 Asafoetida interact with any other medications?
Yes. Asafoetida has 289 documented drug interactions in our database — Gabapentin 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 Gabapentin interact with any supplements?
Yes. Gabapentin has documented interactions with 106 supplements in our database — Asafoetida is not one of them. The Gabapentin interaction page linked on this page lists every one, ranked by severity.
