The Neurontin effects are simply supposed to help people who suffer epilepsy from having so many seizures, and to decrease the severity of the any seizures they might suffer. Unfortunately, the side effects might be more serious than the illness itself. Patients who take this medication are more likely to contemplate suicide and act upon those thoughts. Younger patients are even more susceptible to the adverse effects. In addition, older patients metabolize the medication more slowly, so the Neurontin tends to build up in their system, thus putting more medication in their systems at one time than is safely recommended. So patients have to weigh the benefits against the risks. It is also incumbent upon the doctor to warn the patient and the pharmacy to include the warning when filling the prescription.
