Learn about the prescription medication gabapentin and the dangers of gabapentin overdose in this informative article.

What Is Gabapentin?

Gabapentin is an anticonvulsant, meaning it is prescribed to help treat seizures. Another common use for this medication is treating nerve pain, especially from shingles.

As a commonly prescribed medication, gabapentin has an elevated risk for misuse and abuse, which can lead to an overdose. Despite being used as a medicine for pain relief, gabapentin is not a narcotic or opioid, nor is it a controlled substance. Instead, it’s found in its own class of medications Medication Assisted Treatment known as gabapentinoids.

Can You Overdose on Gabapentin?

Gabapentin is one of the safer methods of medicinal pain relief, as it is not an opioid. However, as with any substance, there is a possibility of overdose. This occurs when too much gabapentin is taken at once.

How Much Gabapentin Leads to an Overdose?

According to the FDA, gabapentin overdose reports have been caused by doses of up to 49 grams. Nonetheless, there are many factors that dictate how much gabapentin is considered excessive, including weight and age. Because there is no specific amount of gabapentin to overdose, it can occur at any time gabapentin is misused, which is why it is important always to take the recommended dose.2

Signs and Symptoms of Gabapentin Overdose

If someone were to take too much gabapentin, they might experience a variety of symptoms due to overdose. A gabapentin overdose can be a dangerous medical emergency, so it is important to be able to recognize the signs and symptoms.

Physical and Behavioral Signs

Many behavioral signs of a gabapentin overdose stem from physical signs. For instance, poor coordination or inability to complete simple tasks may occur as a result of double vision or loss of muscle control. Thus, it’s important to understand both the behavioral and the physical signs when identifying a potential gabapentin overdose.

Gabapentin Overdose Treatment Options

Gabapentin overdose treatments can target the side effects of the overdose itself and aid in the recovery from gabapentin abuse.

Gabapentin Detox

When a substance is consumed regularly for long periods of time, the body and mind can become dependent on it to function normally. This is true for gabapentin, although it has a lower risk of addiction than other substances. Thus, detox is necessary to help slowly restore the body to its natural form.

However, in extreme abuse cases, detoxing, or withdrawing from the substance, can lead to harsh or severe withdrawal symptoms. Therefore, medically-assisted detox at a treatment facility is recommended to ensure a safe and comfortable recovery.

Inpatient and Outpatient Treatment Programs

Inpatient and outpatient treatments provide two similar but unique methods of approaching treatment for a gabapentin addiction.

Inpatient treatment offers around-the-clock care with little to no access to triggers. This is better for more severe cases of substance use disorder or those with a higher risk for relapse, such as during detox. Outpatient treatment, however, is more time-efficient and allows individuals to receive care a few times a week while continuing their usual routine (e.g., work, at-home duties, school).

Support Groups

Sometimes, it can be difficult to connect with professionals. Support groups offer a way to connect with peers in similar situations and circumstances, providing the opportunity to be both a mentor and a mentee in a safe, secure environment.
