Gabapentin is structurally related to GABA.GABA (Gamma aminobutyric acid) is a neurotransmitter in your brain. The way Gabapentin works is by changing the way in which your nerves send messages to your brain. Gabapentin can in this way reduce your pain.

17 Must Know tips:

1) If you are taking this pill three times a day to treat your nerve pain, do not skip or forget taking a dose as it won’t be as effective after 12 hours as it has a shorter half-life of 5-7 hours. This is because you want steady doses of this medication to be effective. If doses are skipped at least half the medication within 5-7 hours would be out of your body.

2) Do not take this medication at the same time as a stomach medication like Maalox or Tums as these medications can interfere with Neurontin. Take the stomach medication 2 hours before or after taking in Neurontin.
