Medically Reviewed by Johnelle Smith, M.D. on April 30, 2021

Gabapentin, also known as Neurontin, is an anti-seizure and pain medication that can stay in the blood for up to two days after use. This detection window may vary based on a variety of personal and biological factors.

How Long Can Gabapentin Be Detected In Your Blood?

Because gabapentin is not a common drug of abuse, a specialized drug panel will need to be used to detect gabapentin in the blood.

Alternative brand names for gabapentin include:

  • Neurontin
  • Gralise
  • Horizant
  • Neuraptine

Gabapentin can also be detected in the urine and hair follicles.

Detecting Gabapentin Through A Blood Test

Gabapentin is a prescription anticonvulsant that can remain in the blood for up to two days after your last dose.

Factors That Affect How Long Gabapentin Stays In The Blood

There are a number of personal and biological factors that can affect how long it will take for gabapentin to be absorbed, metabolized, and eliminated from the bloodstream.

Factors that can affect the detection time of gabapentin include:

  • age
  • dosage
  • duration of use
  • poor kidney function
  • use of other drugs (e.g. opioids, alcohol, benzodiazepines)
  • body fat percentage

Average detection times for gabapentin will generally be extended for people who have impaired renal (kidney) function, due to how the drug is metabolized.

Why Do People Get Their Blood Tested For Gabapentin?

Gabapentin has been increasingly reported as a drug of abuse among people with a previous history of substance abuse and addiction.

While not known to have a high addiction potential, gabapentin can produce mild euphoric effects that may be sought out by people without access to other drugs.

Gabapentin abuse may lead to physical dependence. If you’re physically dependent on gabapentin as a result of drug abuse, seeking out a detox program may be recommended.

Finding Treatment For Gabapentin Abuse And Addiction

It’s important to take gabapentin exactly as prescribed. Abusing gabapentin can be dangerous, especially if it’s taken with other powerful drugs.

Treatment options for gabapentin abuse may involve:

  • detox
  • counseling
  • pain management
