Stopping NEURONTIN suddenly can cause serious problems.
NEURONTIN can cause serious side effects including:
1. Like other antiepileptic drugs, NEURONTIN may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.

2.Changes in behavior and thinking - Using NEURONTIN in children 3 to 12 years of age can cause emotional changes, aggressive behavior, problems with concentration, restlessness, changes in school performance, and hyperactivity.
3. NEURONTIN may cause a serious or life-threatening allergic reaction that may affect your skin or other parts of your body such as your liver or blood cells.

- swollen glands that do not go away
- swelling of your lip and tongue
- yellowing of your skin or of the whites of the eyes
