Overview
Lamotrix 100mg Tablet contains lamotrigine 100mg, an anticonvulsant (antiepileptic) medicine that is also used as a mood stabiliser. It is used to treat certain types of epilepsy and to help prevent mood episodes, particularly depressive episodes, in bipolar disorder. This product is manufactured by Medochemie Ltd.
Lamotrigine works mainly by blocking voltage-sensitive sodium channels on nerve cell membranes, which stabilises overactive neurons and reduces the release of excitatory neurotransmitters such as glutamate. This helps prevent the abnormal, excessive electrical activity that causes seizures and is also thought to underlie its mood-stabilising effect.
How it Works
Lamotrigine blocks voltage-gated sodium channels in a use-dependent manner, meaning it preferentially dampens rapidly firing neurons typical of a seizure while having less effect on normal nerve activity. By stabilising these channels, it reduces the release of glutamate and other excitatory neurotransmitters, calming abnormal electrical activity in the brain.
Directions for Use
Take Lamotrix 100mg Tablet exactly as prescribed, at the same time each day, with or without food. Swallow the tablet whole with water; it can be chewed or dispersed in water if swallowing whole is difficult, following your doctor’s or pharmacist’s specific instructions. Do not stop this medicine suddenly, as abruptly stopping an antiepileptic medicine can trigger seizures – your doctor will advise how to reduce the dose gradually if treatment needs to be stopped.
Dosage
Lamotrix 100mg Tablet must be started at a low dose and increased very slowly, following a specific titration schedule set by your doctor – this schedule differs depending on whether you are also taking valproate or certain other antiepileptic medicines, as these change how quickly lamotrigine can be increased. Never change your dose or titration speed on your own, even if you feel your seizures or mood are not yet fully controlled, as increasing the dose too quickly significantly raises the risk of a serious skin reaction.

Drug / Food Interactions
- Sodium valproate significantly increases lamotrigine blood levels, so a much slower titration and lower dose is required when the two are combined
- Carbamazepine, phenytoin, and phenobarbital can lower lamotrigine levels by speeding up its breakdown, often requiring a higher lamotrigine dose
- Oestrogen-containing hormonal contraceptives can lower lamotrigine levels, and lamotrigine may also affect contraceptive hormone levels – discuss contraception planning with your doctor
- Alcohol may increase drowsiness and dizziness when combined with lamotrigine
Quick Tips

- Do not stop this medicine suddenly without medical advice, even if you feel well
- Tell your doctor before starting or stopping hormonal contraception, as it can interact with lamotrigine levels
- Avoid or limit alcohol, as it can add to dizziness and drowsiness

Frequently Asked Questions
What is Lamotrix 100mg Tablet used for?
Lamotrix 100mg Tablet is used to treat certain types of epilepsy and, in adults, to help prevent the recurrence of mood episodes, particularly depression, in bipolar disorder.
Why does my doctor start me on such a low dose and increase it so slowly?
Lamotrigine carries a risk of serious skin reactions, including Stevens-Johnson syndrome, which is significantly more likely if the dose is increased too quickly. A slow, carefully planned titration schedule reduces this risk substantially.
What should I do if I develop a skin rash while taking this medicine?
Stop taking the medicine and seek medical attention immediately, especially if the rash is accompanied by fever, blistering, or involvement of the mouth, eyes, or genital area, as these can be early signs of a serious reaction.
Can I stop taking this medicine suddenly if I feel better?
No, stopping an antiepileptic medicine suddenly can trigger seizures, even if you feel well. Your doctor will advise a gradual dose reduction if treatment needs to change or stop.
Can I take this medicine if I use hormonal birth control?
Yes, but tell your doctor, as oestrogen-containing contraceptives can lower lamotrigine levels and lamotrigine can affect certain hormonal contraceptives – your doctor may need to monitor or adjust your treatment plan.
What should I do if I miss a dose of Lamotrix 100mg Tablet?
Take the missed dose as soon as you remember, unless it is almost time for your next dose – in that case, skip the missed dose and continue as normal. Do not double the dose, and contact your doctor if you miss several doses in a row, as restarting may require a new titration schedule.
