Does Gabapentin Show Up in a Drug Test?

Those who are taking Gabapentin with a prescription or without are wondering, does Gabapentin show up on a drug test in 2018? The answer is usually no. Gabapentin is not a controlled substance or drug so most drug tests will not test for this particular drug.

What is Gabapentin?

Gabapentin is used for the treatment of partial onset seizures. This is used in adults and patients three years and older. Gabapentin is taken orally with or without food and the capsules should be swallowed whole with water. Gabapentin should only be reduced by a doctor because of the side effects that are possible. Gabapentin should be weaned slowly out of your body to reduce the risks involved.

Warnings and Precautions

Gabapentin has been linked to Drug Reaction with Eosinophilia and Systemic Symptoms or DRESS. This is also known as multiorgan hypersensitivity to the drug. Some reactions are fatal or life threatening. DRESS may occur with the following symptoms:

  • Fever
  • Rash
  • Lymphadenopathy
  • Hepatitis
  • Nephritis
  • Hematological Abnormalities
  • Myocarditis
  • Myositis (Resembling an acute viral infection)
  • Eosinophilia

If any of these signs of Hypersensitivity occur you should be checked out by a doctor. Also, Gabapentin should be discontinued if you are unable to identify why the symptoms are happening. Contact a doctor immediately.

If you are using Gabapentin recreationally, which is not recommended, you are more likely to notice signs of a reaction or side effect. If you notice signs, you should contact for help immediately.

Drug Tests

Gabapentin has an elimination half-life. A half-life of a medication is the time it will take your body to reduce blood levels by about half. Gabapentin’s half-life is about five to seven hours. It will take about five times the elimination of half-lives for a medication to be eliminated from a person’s system. Therefore, it will take Gabapentin about 38.5 hours to be completely cleared from your system. To figure this out you would take 5.5 and multiply it by seven hours.

There are however, other factors to consider when you are preparing for a drug test and wondering if Gabapentin is out of your system. You should consider how much you have taken the drug as well as how often you take the drug. Secondly, you need to keep your metabolic rate in mind. A slower metabolism will increase the time the drug will remain in your body. Third, your age and health. The older you are the more time the drug will stay in your system. If you have poor health, the drug will likely stay in your system longer as well. Lastly, your body mass needs to be taken into consideration. The larger you are the longer Gabapentin, or any drug will stay in your system.

However, since Gabapentin is not a controlled substance or drug it is usually not tested for in many run-of-the mill drug screens. The only way you would be screened for this drug is if you are thought to have used it and the probation officer or employer has likely proof.
