Brief Answer:
It is an anti epileptic drug

Detailed Answer:
That is a bit on the high side and it is a bit unlikely to have more effect if used more than four times a day which is the usual maximal dose. However, it is quite a safe drug and the only side effect from it that is common is (mild) sedation.

It is a drug for epilepsy and not a narcotic. None the less, it is often helpful for pain IF the pain is from a nerve that is irritated, hurt, damaged, and/or causing pain. Symptoms of nerve pain are pain that runs in the direction of a nerve, has the character of a nerve pain (electrical, shooting, often with a numb or temperature component), and often has symptoms of making a sensation that should not be painful be painful and increased pain from a minor stimulation. The drug is particularly good at stopping this increased sensitivity and it does not have the consequences of narcotic pain medication.

Brief Answer:
seems an ideal drug

Detailed Answer:
It is often used with nerve trauma...surgical and otherwise. Often, what seems like a headache is an irritated nerve. Gabapentin is probably the most commonly used drug for it because it is quite safe. Furthermore with a brain injury, its anti epileptic effects are likely to be beneficial.
