Why is Lamictal CD prescribed?

Lamictal is prescribed to control seizures in people with epilepsy. It is also used to control a serious form of epilepsy known as Lennox-Gastaut syndrome. Lamictal is used in combination with other antiepileptic medications or as a replacement for a medication such as carbamazepine, phenytoin, phenobarbital, primidone, or valproate.

In addition, Lamictal is used to help prevent the manic and/or depressive phases of bipolar disorder.

Most important fact about Lamictal CD

The rash could become severe and even dangerous, particularly in children. Signs of a more serious reaction include hives, fever, swollen lymph glands, painful sores in the mouth or around the eyes, or swelling of the lips or tongue. A slight possibility of this problem remains for up to 6 months.
