About the Drug:

Neurontin® is another Epilepsy medication that is being used as an effective preventive or prophylactic Migraine regiment. As Migraine and Epilepsy are Related diseases, this is actually a sound approach.  


Neurontin® is an antiepileptic drug, prescribed as adjunctive therapy in the treatment of partial seizures with and without secondary generalization in patients over 12 years of age with epilepsy. Neurontin is also indicated as adjunctive therapy in the treatment of partial seizures in pediatric patients age 3-12 years.. It is typically added to the treatment regimen when other drugs fail to fully control a patient's attacks.


Do not abruptly stop taking Neurontin. If the drug isn't withdrawn gradually, seizures may be caused, even in patients who do not normally experience seizures.

Neurontin may cause dizziness, somnolence and other symptoms and signs of CNS depression. Accordingly, they should be advised neither to drive a car nor to operate other complex machinery until they have gained sufficient experience on Neurontin to gauge whether or not it affects their mental and/or motor performance adversely.
