What is the Most Important Information I Should Know About Lamotrigine

1. Lamotrigine may cause a serious skin rash that may cause you to be hospitalized or even cause death.

There is no way to tell if a mild rash will become more serious. A serious skin rash can happen at any time during your treatment with lamotrigine, but is more likely to happen within the first 2 to 8 weeks of treatment. Children between 2 to 16 years of age have a higher chance of getting this serious skin rash while taking lamotrigine.

The risk of getting a serious skin rash is higher if you:

  • take lamotrigine while taking valproate ((valproic acid) or (divalproex sodium))
  • take a higher starting dose of lamotrigine than your healthcare provider prescribed
  • increase your dose of lamotrigine faster than prescribed.

Call your healthcare provider right away if you have any of the following:

  • a skin rash
  • blistering or peeling of your skin
  • hives
  • painful sores in your mouth or around your eyes

These symptoms may be the first signs of a serious skin reaction. A healthcare provider should examine you to decide if you should continue taking lamotrigine.

2. Other serious reactions, including serious blood problems or liver problems .

Lamotrigine can also cause other types of allergic reactions or serious problems that may affect organs and other parts of your body like your liver or blood cells. You may or may not have a rash with these types of reactions. Call your healthcare provider right away if you have any of these symptoms:

  • fever
  • frequent infections
  • severe muscle pain
  • swelling of your face, eyes, lips, or tongue
  • swollen lymph glands
  • unusual bruising or bleeding
  • weakness, fatigue
  • yellowing of your skin or the white part of your eyes

3. Like other antiepileptic drugs, lamotrigine may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.

Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • attempt to commit suicidenew or worse depression
  • new or worse anxietyfeeling agitated or restless
  • panic attacks
  • trouble sleeping (insomnia)
  • new or worse irritability
  • acting aggressive, being angry, or violent

  • an extreme increase in activity and talking (mania)
  • other unusual changes in behavior or mood 
    Do not stop lamotrigine without first talking to a healthcare provider.
  • Stopping lamotrigine suddenly can cause serious problems.
  • Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes.

  • Keep all follow-up visits with your healthcare provider as scheduled.
  • Call your healthcare provider between visits as needed, especially if you are worriedabout symptoms.

4. Lamotrigine may rarely cause aseptic meningitis, a serious inflammation of the protective membrane that covers the brain and spinal cord.

  • Headache
  • Fever
  • Nausea
  • Vomiting
  • Stiff neck
  • Rash
  • Unusual sensitivity to light
  • Muscle pains
