Gabapentin is a drug that has been used for years to treat epilepsy and other neurological disorders. It works by modulating the release of neurotransmitters such as GABA (gamma-aminobutyric acid) in the brain. Thus, it directly affects mood and cognition.

If you find yourself experiencing anxiety or severe depression, your doctor may prescribe this medication to help you cope with the symptoms. It is also prescribed to those with bipolar disorder and in suitable medical conditions.

How Does Gabapentin Work?


Gabapentin reduces the number of neurons that are firing in your brain.

By doing so, this medication can help improve mood and cognition while also reducing anxiety or depression-related symptoms.

The neurotransmitter GABA is responsible for slowing down neuronal activity when it binds to its receptors found on nerve cells.

In other words, it reduces your brain’s response to stress and anxiety by blocking neurotransmitters. Such as glutamate, norepinephrine, dopamine, epinephrine (adrenaline), serotonin, and others from binding on receptor sites in the central nervous system.

Thus, the neurotransmitter GABA is responsible for slowing down neuronal activity. In this way, it decreases anxiety and stress levels to promote a sense of calmness throughout your body. It leads to improved moods, feelings of happiness or well-being, and relief from depression symptoms.

Gabapentin and Its Uses

Gabapentin is an anticonvulsant medication that was originally developed to treat epilepsy in the early 1990s. Since it works by slowing down nerve impulses throughout your central nervous system. Thus, gabapentin can be used off-label to treat different conditions such as:

Depression And Bipolar Disorder

For individuals who do not respond to, or cannot tolerate antidepressant medications.

Gabapentin And Its Effect

On Brain

Gabapentin has little or no effect on the GABA levels found in your brain. Because it does not readily cross the blood-brain barrier.

It doesn’t interfere with normal brain activity and has few interactions with other medications.

However, it may affect an individual’s thinking abilities as well as judgment skills. Especially when used in high doses for prolonged periods. In some rare instances, gabapentin may also increase an individual’s risk of seizures.

On Other Organs

In some cases, gabapentin can also affect organs outside of the central nervous system and digestive tracts. Such as your kidneys or liver.

This drug is processed through the kidneys and excreted by the bladder. It means that it may accumulate in your body if you have impaired kidney function.

Gabapentin can also affect your liver. In some cases, if you have a pre-existing condition. Such as cirrhosis or hepatitis B and C infection.

Also, there may be an increased risk of developing additional neuropsychiatric symptoms due to the damage to this organ’s functions.

In some cases, an individual can experience certain physical side effects such as:

  • Decreased appetite
  • Hair loss (alopecia)
  • Increased sweating
  • Rash or hives
  • Swelling

Gabapentin Dosage Recommendations & Administration 

Your doctor will recommend the right dosage for you after assessing your symptoms, age, and overall health. It will be administered orally in three divided doses. However, it may also be taken once daily without titrating based on the condition.

When To Stop Administrating Gabapentin


Gabapentin is not recommended for long-term use. It’s generally prescribed for short periods to manage seizures, anxiety, depression, or neuropathic pain associated with other conditions. Such as diabetic peripheral neuropathy (DPN).

If you have been using this medication over a prolonged period and would like to discontinue the treatment. Then, you must seek advice from your physician on how they can help manage withdrawal symptoms effectively.

It’s also essential for individuals who are taking gabapentin at the same time as other medications or supplements to discuss with their medical practitioner if there have been any changes in mood, behavior, thoughts, or feelings. This is because there may be an increased risk of developing certain side effects such as suicidal ideation, aggression, and hostility.

Therefore, physicians advise not to stop the dosage of gabapentin suddenly. Hence, it is important to stop taking this medication under the supervision of your doctors or other medical providers.

If you are experiencing side effects while on gabapentin, call your physician immediately for instructions. Ask about how to manage them properly without stopping treatment entirely. Your doctor may suggest that you adjust your dose or switch medications to treat your condition.

NOTE: Even though gabapentin is not a narcotic or opioid-based medication like other treatments for anxiety such as Xanax (alprazolam). It can still be habit-forming potential to cause physical dependence which may result in withdrawal symptoms if abruptly stopped after extended use of this drug.
