Safety at a glance
This score comes from an AI-written analysis of the pair. Our interaction rules check it and can only make it stricter, never milder. Informational only: it can't account for your medications, conditions, or genetics.
What the AI-written analysis says
Combining kava with gabapentin may pose risks due to potential additive effects on the central nervous system, leading to increased sedation or respiratory depression. Both substances have limited evidence regarding their interactions, and caution is advised.
Gabapentin is a prescription medication. This page describes publicly documented interactions — it can't see your dose, your other prescriptions, or your labs. Discuss any supplement with the prescriber or pharmacist who manages this medication before combining.

Watch out for
- Combining two or more central-nervous-system depressants can cause heavy sedation and badly impaired alertness, much more than either one alone. These include phenibut, kratom, kava, tianeptine, amanita (muscimol), blue lotus, benzodiazepines (e.g. Xanax), the sleep medicines zolpidem (Ambien), eszopiclone (Lunesta) and zaleplon (Sonata), gabapentin/pregabalin, opioids, sedating antidepressants such as trazodone and mirtazapine, sedating antipsychotics such as olanzapine and haloperidol, sedating antihistamines and anticholinergics such as promethazine, diphenhydramine and scopolamine, clonidine, and topiramate or zonisamide. With phenibut, kratom, kava, tianeptine, amanita or blue lotus, and with opioids, benzodiazepines, the sleep medicines above, or gabapentin and pregabalin, the combination can also cause dangerous, potentially fatal slowed breathing. The risk is much higher with alcohol. Ask a pharmacist, or the prescriber if any of these was prescribed, before you combine them. If any of these is a prescription, do not stop or change it on your own, because stopping some of these suddenly is dangerous in itself. Get emergency care for extreme drowsiness, confusion, or slow/shallow breathing.
- Consult with a healthcare provider before combining kava with gabapentin due to potential increased sedation and respiratory depression.
