What is the most important information I should know about Lamictal?
1. Lamictal 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 Lamictal, but is more likely to happen within the first 2 to 8 weeks of treatment. Children and teenagers aged between 2 and 17 years have a higher chance of getting this serious skin rash while taking Lamictal.
The risk of getting a serious skin rash is higher if you:
- take Lamictal while taking valproate [Depakene (valproic acid) or Depakote (divalproex sodium)].
- take a higher starting dose of Lamictal than your healthcare provider prescribed.
- increase your dose of Lamictal 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
- 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 Lamictal.
2. Other serious reactions, including serious blood problems or liver problems. Lamictal 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:
- 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, Lamictal 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 suicide
- new or worse depression
- new or worse anxiety
- feeling agitated or restless
- panic attacks
- trouble sleeping (insomnia)
- new or worse irritability
- acting aggressive, being angry, or violent
- acting on dangerous impulses
- an extreme increase in activity and talking (mania)
- other unusual changes in behavior or mood
Do not stop Lamictal without first talking to a healthcare provider.
- Stopping Lamictal 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.
How can I watch for early symptoms of suicidal thoughts and actions in myself or a family member?
- Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings.
- Keep all follow-up visits with your healthcare provider as scheduled.
- Call your healthcare provider between visits as needed, especially if you are worried about symptoms.
4. Lamictal may cause aseptic meningitis, a serious inflammation of the protective membrane that covers the brain and spinal cord. Call your healthcare provider right away if you have any of the following symptoms:
- stiff neck
- unusual sensitivity to light
- muscle pains
Meningitis has many causes other than Lamictal, which your doctor would check for if you developed meningitis while taking Lamictal.
Lamictal can cause other serious side effects. For more information ask your healthcare provider or pharmacist. Tell your healthcare provider if you have any side effect that bothers you. Be sure to read the section below entitled “What are the possible side effects of Lamictal?”
5. People prescribed Lamictal have sometimes been given the wrong medicine because many medicines have names similar to Lamictal, so always check that you receive Lamictal.
Taking the wrong medication can cause serious health problems. When your healthcare provider gives you a prescription for Lamictal:
- Make sure you can read it clearly.
- Talk to your pharmacist to check that you are given the correct medicine.
- Each time you fill your prescription, check the tablets you receive are Lamictal tablets.
