Generic Name: Lamotrigine
Product Name: Lamitrin
Lamitrin is used for the treatment of epilepsy in adults and children; and belongs to a group of medicines called “anti-epileptic drugs“. Usually Lamitrin is used initially in addition to other medicines for the treatment of epilepsy. Lamitrin is used in partial (seizures that affect only one part of the brain) or generalised seizures (seizures that affect the whole brain) including Lennox-Gastaut Syndrome (a severe form of epilepsy characterised by several seizure types). Your doctor may have prescribed Lamitrin for another reason. Ask your doctor if you have any questions about why it has been prescribed for you.
The precise mechanism of the action of Elmendos (Lamotrigine) is not certain. The results of studies show that Elmendos (Lamotrigine) can block sodium channels and reduce the release of glutamate (an excitatory messenger associated with epilepsy). It is possible that these effects limit the seizures.
Your doctor will decide what dose and how long you will receive Lamitrin . Take your tablets as directed by your doctor. Never change the dose yourself. Do not increase the dose more quickly than you have been told. Your doctor will be able to tell you:
- how many tablets to take at each dose.
- how many doses to take each day.
- when to take each of your doses.
The label on the container that the tablets were supplied in will give the same information. If there is something that you do not understand ask your doctor. It is usual for the dose to start at quite a low level and be slowly increased during the first few weeks of treatment. The dose your doctor prescribes will generally depend on any other anti-epileptic medications you are taking for the treatment of epilepsy and your response to Lamitrin (Lamotrigine).Hormonal contraceptives: If you start or stop taking hormonal contraceptives (e.g. Oral contraceptive pill) while taking Lamitrin (Lamotrigine) your doctor may need to adjust the dose of Lamitrin (Lamotrigine) depending on how well your condition is being treated.
