Gabapentin Oral: Uses, Side Effect, Dosage and Warnings

Gabapentin was first approved for use in 1993.

Gabapentin is marketed under the brand name Neurontin. It reduces the incidence of hot flashes in women and menopausal women and patients with breast cancer. But antidepressants work in a similar way and estrogen treatment protects against hot flashes.

What is Gabapentin?

Gabapentin is technically an anticonvulsant used to treat seizures. The exact mechanism is known but it does appear yet to reduce the release of excitatory neurotransmitters. So what does all that mean well what experts usually tell people it’s a seizure medicine. That’s also used to treat pain. Because it seems to have a calming effect on the nerves and that’s basically what happens.

 How does it work?

Gabapentin belongs to a class of medications called anti-epileptics. A drug class is a group of medications that work in a similar way. These drugs are often used to treat these conditions.

Uses for Gabapentin

Drug Dependence

Gabapentin does not work on cocaine addiction and methamphetamine use nor does it increase smoking cessation. Gabapentin does not significantly reduce opiate withdrawal symptoms. There is insufficient evidence for its use in cannabis dependence.

Neuropathic pain

Gabapentin is recommended as a first-line treatment for chronic neuropathic pain by various medical managers. This is a general recommendation that applies to all neuropathic pain syndromes with the exception of trigeminal neuralgia. Regarding some diagnoses, the best evidence is available for gabapentin treatment for postherpetic neuralgia and diabetic neuropathy. Gabapentin is approved by the US reference. In addition to these two neuropathies, a guide to the European Federation of Neurological Societies notes the efficacy of gabapentin for central pain. A combination of gabapentin-containing opioids or nortriptyline may work better than a single drug.


There is little research on the use of gabapentin in the treatment of anxiety disorders. In a controlled trial of anxious breast cancer survivors and in a trial of social phobia gabapentin significantly reduced anxiety levels. According to pneumonia, gabapentin is ineffective. 

On the other hand, some psychiatrists recognize the “potential role of gabapentin in anxiety disorders especially social phobia and panic disorder” based on “case reports and poor visual acuity” or state that controlled studies are not shown in -gabapentin to be very effective in psychological indicators; “however clinically it works”
