Hi Dear
The long term effects of
Neurontin are still not known completely. However,
Neurontin is a relatively safe and effective treatment for pain. Many patients with painful neruopathy have used Neurontin for many years. Typically the side-effects include somnolence, dizziness, and imbalance. Since you have been using Neurontin for 9 years, there does not seem to be a problem continuing it, even at a slightly increased dose.
