What this medicine is used for
The name of your medicine is APO-Lamotrigine. It contains the active ingredient lamotrigine.
Lamotrigine belongs to a group of medicines called "anti-epileptic drugs".
It is used to treat epilepsy in adults and children aged 2 years and over.
Usually lamotrigine is used in addition to other medicines for the treatment of epilepsy. Lamotrigine is used in partial seizures (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).
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that this medicine is addictive.
Use in children
This medicine may be used to treat epilepsy in children 2 years of age and over.

It is recommended that women on antiepileptic drugs, including lamotrigine receive pre-pregnancy counselling regarding the risk to their unborn child.

- other anti-epileptic drugs including carbamazepine, phenobarbitone and primidone
- any form of hormonal contraception (e.g. "the pill") or HRT
- rifampicin, which is often used to treat infections including tuberculosis

How much to take
Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
Do not stop taking your medicine or change your dosage without first checking with your doctor.
Usually your doctor will prescribe a low dose to start and gradually increase the dose during the first few weeks of treatment. The dose that your doctor prescribes will often depend on other anti-epileptic medications you are taking and your response to lamotrigine.
If you start or stop taking hormonal contraceptives (e.g. "the pill") while taking lamotrigine, your doctor may need to adjust the dose of lamotrigine depending on how well your condition is being treated.
You should tell your doctor if there are any changes in your menstrual pattern, such as breakthrough bleeding.
If you become pregnant your doctor may need to change your dose of lamotrigine or switch you to a different medicine.
