As many of us don’t know about a specific drug or medicine, named Gabapentin(sold as a brand known as Neurontin), that is used to treat certain medical conditions in people. It is important to gain some knowledge about the drug and how long it stays in the system. It is crucial to understand how much time the drug gabapentin takes to get eliminated for managing medication schedules, for drug tests, and to safely discontinue treatment. This time period can be differentiated based on individual factors, such as metabolism, kidney function, and the dosage you’ve been taking. So let’s understand what gabapentin is and how long it stays in your body. Overuse of gabapentin causes gabapentin use disorder; gabapentin dependency treatment is available in a prescription drug addiction rehab center.
What is Gabapentin & Its Half-life?
Gabapentin, also known as gamma aminobutyric acid (GABA), is a prescribed medicine by the doctor when you are suffering from nerve pain caused by diabetic neuropathy, central pain, and postherpetic neuralgia. It is treated by minimising abnormal excitement in the brain. It gives relief from the pain caused by PHN by changing the way you feel the pain. In the market, there are multiple brands of gabapentin available, such as Gralise, Horizant, and others. Gabapentin is mostly used with other drugs to treat specific conditions like seizures, pain, and anxiety. Gabapentin comes in a class called anticonvulsants.
Typically, gabapentin has a half-life of not more than 6-7 hours. It means the drug takes 6-7 hours to get eliminated from your system. To estimate how long it stays in your system, it generally takes five half-lives of the drug to get mostly cleared from your body. However, gabapentin is one of a few drug which is not metabolised in the liver; instead, it is metabolised by the kidneys. While gabapentine metabolises and leaves the body within 6-7 half-lives, certain factors can influence this time range.
Why is Gabapentin prescribed?
Gabapentin is generally prescribed for the treatment of epilepsy. In epilepsy, it stops seizures by reducing the abnormal activities occurs in the brain. It is also used to:
- Prevent or control partial seizures in adults and children aged 3 and older.
- After a certain time of having chicken pox, Shingles, a very painful rash, develops. Gabapentin helps in getting relieved in nerve pain following shingles in adults.
- Gabapentin also helps in the treatment of restless leg syndrome and PHN. Horizant, a branded gabapentin enacarbil product, is prescribed for RLS and PHN.
How long Gabapentine stays in your system
Typically, the presence of gabapentin cannot be tested from the drug screen. A few points can be considered for how long gabapentin can be detected in your body:
-
- Blood test: gabapentin can be detected through a blood test within the time range of 5-7 hours.
- Hair test: Hair follicle test might detect the presence of gabapentin for up to 90 days, but this test is highly unreliable and performed rarely.
- Urine test: For up to 3 days, gabapentin can be detected in most individuals through urinalysis because urine testing provides the most reliable detection window.
Factors affecting how long Gabapentin stays in your system
While the elimination time of gabapentin is less influenced by dosage than other drugs, taking high dosages can still prolong its presence in your body. Several other factors affect how quickly gabapentin is eliminated:
Age:
- Older people tend to eliminate gabapentin more slowly than younger people because, naturally, kidney function declines with increasing age.
- Older people have 30%-50% chance of a longer clearance time.
- Younger people mostly clear gabapentin faster
- Children may have a faster clearance rate.
Kidney function:
- Since gabapentin is eliminated through the kidneys, impaired kidney function slows the drug clearance.
- No sign of liver failure occurs.
- Kidney disease automatically increases elimination time.
Kidney function categories:
- Normal function: Standard half-life of 5-7 hours.
- Mild impairment: Half-life of 7-12 hours.
- Moderate impairment: 12-24 hours of half-life
- Severe impairment: Half-life of 24-52 hours
- Dialysis: To remove the drug, dialysis is necessary.
Conclusion
It is essential to understand how long gabapentin stays in your system to manage your health effectively. If you are to go for a surgery, to face a drug test, or to ensure your medication regimen is functioning properly. You should always discuss your concerns with your doctor to ensure that you have the most accurate and personalised information regarding your system.
