Quick summary

Lamictal is a brand name for lamotrigine, a medicine used for epilepsy and bipolar disorder. This page summarises the main uses, common side effects, important precautions, missed-dose advice, and storage information from the provided content.

Medical disclaimer: This article is for general information only and does not replace the official patient leaflet, product information, or advice from a doctor or pharmacist. Do not use it to diagnose a condition or to change how you take any medicine.

What is Lamictal?

Lamictal is the brand name for lamotrigine, an antiepileptic medicine. It is used in the treatment of epilepsy and bipolar disorder. The medicine is manufactured by GlaxoSmithKline and has been approved by the European Medicines Agency for the indications described in the source content.

Lamictal is available in different tablet strengths, including 50 mg and 100 mg forms. The exact formulation and strength prescribed will depend on the condition being treated and the treatment plan chosen by the healthcare professional.

What are Lamictal tablets used for?

According to the provided content, Lamictal tablets are used for:

  • Epilepsy, including use as monotherapy or as add-on treatment in adults and children.
  • Bipolar disorder, especially for preventing depressive episodes in adults.
  • Managing certain seizure types, including partial seizures and generalized seizures.

Lamotrigine works by helping to stabilise abnormal electrical activity in the brain. This is why it can be used in seizure control and in the prevention of mood episodes in bipolar disorder.

What are the side effects of Lamictal?

Lamictal is generally described as well tolerated, but side effects can occur. The source content lists the following common effects:

  • Dizziness
  • Headache
  • Nausea and vomiting
  • Skin rash

Skin rash is especially important because it can sometimes be severe. Serious skin reactions, including Stevens-Johnson syndrome, have been reported. The source notes that these reactions often occur within the first 2 to 8 weeks of treatment.

Symptoms that need urgent medical attention include rash, blistering, and pain in the mouth or eyes. The risk may be higher when Lamictal is used with certain medicines such as valproate or divalproex.

How should Lamictal be taken?

Lamictal should be taken exactly as prescribed. The source content says it can be taken with or without food. It also notes that tablets should not be crushed or split, especially dispersible forms.

Treatment usually starts with a low dose that is increased gradually. This stepwise approach is used to help reduce side effects. Patients should not change the dose on their own and should follow the schedule given by their healthcare professional.

What precautions should be followed?

Before starting Lamictal, the source content says patients should discuss their medical history and current medicines with a healthcare professional, especially:

  • Any previous allergy to lamotrigine or related medicines
  • Other medicines that may interact with Lamictal
  • Pregnancy or breastfeeding status

Regular monitoring is important, particularly for skin changes and other unusual symptoms. The source also notes that children may be at higher risk of severe reactions.

What should I do if I miss a dose?

If a dose is missed, the source content advises taking it as soon as it is remembered. If it is nearly time for the next dose, the missed dose should be skipped and the regular schedule resumed.

Do not take a double dose to make up for a missed one. If missed doses happen often, it may help to use reminders or a medication organiser.

How should Lamictal be stored and disposed of?

Lamictal should be stored at room temperature, away from moisture and heat. It should be kept out of reach of children and pets.

Unused or expired tablets should be disposed of safely. A pharmacist can advise on local disposal options. Do not use tablets past their expiry date.
