Gabapentin Abuse

How Common Is Gabapentin Abuse?

Two surveys reported that the misuse of gabapentin was 1.1% of the general population and 22% in drug abuse treatment centers.

Gabapentin is at a relatively higher risk of use because of its accessibility. Gabapentin has not been named a controlled substance, making it easier to obtain.

Some may have been prescribed it, and others may get them from a friend or family member that has been prescribed it.

"Gabapentin abuse statistics: 1.1% of the general population was misusing it and 22% in drug abuse treatment centers were misusing it" text is written and an illustration of a woman holding a tablet of gabapentin is in between the two statistics.

How Do People Abuse Gabapentin?

Gabapentin has the potential for abuse, dependence, and withdrawal.

Individuals may abuse gabapentin by using it as a way to self-medicate. They may use it to produce calming effects, relaxation, and euphoria.

Gabapentin is also commonly misused with other substances, especially opioids, as a way to intensify their effects.

A person who is prescribed gabapentin may misuse it by taking more than the prescribed dosage or using it for entirely different reasons than what it is meant for.

A common sign of gabapentin abuse is when patients that are prescribed gabapentin frequently ask for early refills.

What Does A Gabapentin High Feel Like?

Those who abuse gabapentin may try to achieve a high that elevates their mood and makes them feel calm and relaxed.

The effects of a gabapentin high can be intensified when mixed with other substances like alcohol or opioid. However, mixing gabapentin with other substances increases the risks of overdose and other adverse effects.

How Do You Treat An Addiction To Gabapentin?

One of the first steps for gabapentin addiction treatment typically involves a medically-supervised detox. Individuals who have developed a dependence will face withdrawal symptoms when they stop taking a drug.

Medically-supervised detox helps people manage withdrawal symptoms in a safe and controlled environment.

There is a wide variety of treatment programs available to fit the needs of each individual. For those who require a higher level of structure and support, inpatient or residential care involves the person living in a facility to receive care.

Others may benefit from less intensive programs, like day treatment or intensive outpatient programs.

Psychotherapy, or talk therapy, is usually a big part of the plan for treating addictions, including gabapentin addiction.

Through talk therapy, a person can begin to understand the connection between their thoughts, feelings, and behaviors. They can learn how to restructure their beliefs and how to practice healthy coping mechanisms.

It is not uncommon for those with a gabapentin addiction to be addicted to other substances.

In this case, it is important that the treatment plan addresses each substance.

Addiction not only hurts the individual but impacts the whole family and the people around them as well.

Going to family therapy can help each member heal together, gain a better understanding, and learn healthy coping mechanisms and ways they can support themselves and one another.

Support groups for those struggling with substance abuse and addiction have also shown to be helpful. Through support groups, a person can relate to and learn from others who may share similar experiences and feel a sense of community and support.
