Quick answer
Gabapentin (Neurontin) is typically detectable in urine for 1–2 days (up to ~3 renal-impaired) after any use. It is screened on standard 12-panel drug tests.
Screened on: 12-panel
Typical cutoff: Specialized urine assay ~2,000 ng/mL where monitored (pain/MAT programs).
Detection window by test type
| urine | |
|---|---|
| Any use | 1–2 days (up to ~3 renal-impaired) |
| saliva | |
| Any use | ~1 day (research) |
| hair | |
| Any use | rarely tested |
| blood | |
| Any use | ~1 day |
Ranges reflect typical published detection windows and vary with dose, frequency, body composition, hydration and the assay used.
Key details
Gabapentin isn't on standard employment panels. Pain clinics, MAT programs, and some probation systems monitor it specifically because of abuse-potential findings — those orders use dedicated assays.
Renal excretion is nearly complete and unchanged, giving it one of the cleaner pharmacokinetic profiles among monitored drugs.
Frequently asked questions
How long does gabapentin (neurontin) stay in your system?
In urine, typical detection is 1–2 days (up to ~3 renal-impaired) (any use). Hair can detect use for up to 90 days and saliva/blood windows are usually shorter.
Will gabapentin (neurontin) show up on a standard drug test?
Yes — Gabapentin (Neurontin) is screened on standard panels (12-panel).
How accurate are these detection windows?
They are typical ranges from published literature and assay documentation, not guarantees. Clearance depends on dose, frequency, metabolism and the specific test cutoff used.
