What is Lamictal Blue (lamotrigine)?
Lamotrigine is an anti-epileptic medication, also called an anticonvulsant.

The immediate-release form of lamotrigine (Lamictal, Lamictal ODT) can be used in children as young as 2 years old when it is given as part of a combination of seizure medications. However, this form should not be used as a single medication in a child or teenager who is younger than 16 years old.
The extended-release form of lamotrigine (Lamictal XR) is for use only in adults and children who are at least 13 years old.
Lamotrigine may also be used for purposes not listed in this medication guide.
What is the most important information I should know about Lamictal Blue (lamotrigine)?
Lamotrigine may cause a severe or life-threatening skin rash, especially in children and in people who take too high of a starting a dose, or those who also take valproic acid (Depakene) or divalproex (Depakote).
Seek emergency medical attention if you have: fever, sore throat, swelling in your face or tongue, burning in your eyes, skin pain, followed by a red or purple skin rash that spreads (especially in the face or upper body) and causes blistering and peeling.
What should I discuss with my healthcare provider before taking Lamictal Blue (lamotrigine)?
You should not take lamotrigine if you are allergic to it.
Lamotrigine may cause a severe or life-threatening skin rash, especially in children and in people who take too high a dose at the start of treatment. Serious skin rash may also be more likely to occur if you are taking lamotrigine together with valproic acid (Depakene) or divalproex (Depakote).
To make sure lamotrigine is safe for you, tell your doctor if you have:
kidney or liver disease;
a history of depression or suicidal thoughts or actions; or
if you are allergic to other seizure medications.
Some people have thoughts about suicide while taking this medicine. Your doctor will need to check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of lamotrigine on the baby.
Birth control pills can make lamotrigine less effective, resulting in increased seizures. Tell your doctor if you start or stop using birth control pills while you are taking lamotrigine. Your lamotrigine dose may need to be changed.
Lamotrigine can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How should I take Lamictal Blue (lamotrigine)?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Taking too much lamotrigine at the start of treatment may increase your risk of a severe life-threatening skin rash.
You may need frequent blood tests to help your doctor make sure you are taking the right dose of lamotrigine.
Extended-release lamotrigine (Lamictal XR) may be used for different conditions than immediate-release lamotrigine is used for. Always check your refills to make sure you have received the correct size, color, and shape of tablet. Ask the pharmacist if you have any questions about the medicine you receive at the pharmacy.
If you switch to lamotrigine from another seizure medicine, carefully follow your doctor's instructions about the timing and dosage of your medications. Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Do not crush, chew, or break the regular or the extended-release tablet. Swallow it whole.
Do not swallow the orally disintegrating tablet (ODT) whole. Place it on your tongue and move it around in your mouth. Allow the tablet to dissolve in your mouth without chewing. Swallow several times as the tablet dissolves. If desired, you may drink liquid to help swallow the dissolved tablet.
To take the chewable dispersible tablet, you may either swallow it whole with a glass of water, or chew it first and then swallow it. You may also place the tablet into 1 teaspoon of water or diluted fruit juice and allow it to disperse in the liquid for about 1 minute. Gently swirl the liquid and then swallow all of the mixture right away. Do not save it for later use.
Do not stop using lamotrigine suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
Wear a medical alert tag or carry an ID card stating that you take lamotrigine. Any medical care provider who treats you should know that you take seizure medication.
Use lamotrigine regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
