Lamictal

Lamictal is used to control seizures from epilepsy as well as the negative effects of bipolar disorder.

Lamictal is used to help prevent seizures, most notably those caused by epilepsy. This medication is an anticonvulsant that is used to manage excess energy in the brain that can lead to a negative episode. It may take several weeks before you begin to feel the full effects of Lamictal. Continue taking your medication regularly during this time to ensure that your body adapts to it as quickly as possible. Once your symptoms begin to disappear, continue your medication as instructed to ensure that they do not return or become worse.

Indications and Usage

Lamictal is the brand name for lamotrigine, an extended release tablet that is used to help manage epilepsy. Lamictal is often used alongside other medications to help manage this condition. You may also be prescribed Lamictal to help manage Lennox-Gastaut syndrome, and may be used to help increase the time between extremely depressive or manic states in those who suffer from bipolar disorder. If you are taking other medications for these disorders, your doctor may gradually decrease these doses as they increase the doses of Lamictal.

If you receive a disintegrating tablet that can be chewed or swallowed with water, read packaging instructions carefully to ensure that you remove it in such a way that it will not start disintegrating before you get it in your mouth. If you are given an extended release tablet you should not chew or crush it when you take your dose. You may take this medication with or without food. Doses are either given once or twice a day, and in some cases will be taken every other day during the early stages of treatment.
