Great Plantain 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 Great Plantain 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. Great Plantain has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (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

What Great Plantain Itself Has Been Linked To

This is not an interaction — nothing below involves Gabapentin. It is the side-effect record for Great Plantain on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Great Plantain, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Great Plantain — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Gabapentin’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Gabapentin column appears here.

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 Great Plantain

What is Great Plantain?

  • Minor wounds and skin irritation
  • Insect bites and stings
  • Coughs and sore throat
  • Digestive upset
  • Mild inflammation

Great Plantain is a common weed traditionally used on the skin for minor wounds and bites, and as a tea for coughs or stomach upset. Human evidence for most of these uses is limited, though the plant appears generally well tolerated. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a health condition.

Plantago major · Plantaginaceae · Leaves and seeds · Tea, capsules, tinctures, topical salves and ointments, fresh crushed leaves (poultice)

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

Great Plantain: dosing

There is no well-established standardized dose for Great Plantain. Traditional use varies widely, and the amount of active compounds differs between products and plant sources.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount. A pharmacist or doctor can help you decide whether it is appropriate for you and review your other medications and health conditions first.

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.

Fatigue 24,972 reports
Nausea 22,728 reports
