Precautions

Drug information provided by: Micromedex

It is important that your doctor check the progress of you or your child at regular visits, especially during the first few months of your treatment with lamotrigine. This will allow your doctor to change your dose, if necessary, and will help reduce any unwanted effects.

It is important to tell your doctor if you become pregnant while using this medicine. Your doctor may want you to join a pregnancy registry for patients taking a seizure medicine.

You should not start or stop using birth control pills or other female hormonal products while you are taking this medicine until you have consulted your doctor.

Tell your doctor right away if you have unusual changes in your menstrual cycle such as breakthrough bleeding while taking lamotrigine and birth control pills or other female hormonal products.

This medicine may increase the effects of alcohol and other central nervous system (CNS) depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for allergies or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; ; medicine for seizures or barbiturates; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using this medicine.

Lamotrigine may cause blurred vision, double vision, clumsiness, unsteadiness, dizziness, or drowsiness. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert, well-coordinated, or able to see well. If these reactions are especially bothersome, check with your doctor.

Skin rash may be a sign of a serious unwanted effect. Check with your doctor immediately if you or your child develop a rash, fever, flu-like symptoms, or swollen glands, or if your seizures becomes worse.

Lamotrigine may cause serious allergic reactions affecting multiple body organs (e.g., liver or kidney). Check with your doctor right away if you or your child have the following symptoms: fever, dark urine, headache, hives, muscle pain or stiffness, stomach pain, unusual tiredness, or yellow eyes or skin.

This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you, your child, or your caregiver notice any of these side effects, tell your doctor or your child's doctor right away.

Check with your doctor right away if you or your child start to have a stiff neck, confusion, drowsiness, fever, chills, headache, nausea or vomiting, rash, or sensitivity to light. These could be symptoms of a rare and serious condition called aseptic meningitis.

Do not stop taking lamotrigine without first checking with your doctor. Stopping this medicine suddenly may cause your seizures to return or to occur more often. Your doctor may want you to gradually reduce the amount you are taking before stopping completely.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
