What is Lamictal ODT?

Lamictal ODT is a medication used to treat epilepsy and is also known as an anticonvulsant.

Lamictal ODT can be used alone or with other medications to treat epileptic seizures in both adults and children. This medicine is also used to help delay mood episodes in adults with bipolar disorder (manic depression).

Immediate-release Lamictal ODT can be used in children as young as 2 years old when given as part of a combination of seizure medications. However, this form should not be used alone in a child or teenager who is younger than 16 years old.

Extended-release Lamictal ODT is only for use in adults and children who are at least 13 years old.

Lamictal ODT may also be used for reasons not mentioned in this medication guide.

How should I take Lamictal ODT?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Taking too much Lamictal ODT 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.

Extended-release and immediate-release Lamictal ODT may be used for different conditions. Always check your refills to make sure you have received the correct size, color, and shape of tablet. Avoid medication errors by using only the form and strength your doctor prescribes.

If you switch to Lamictal ODT from another seizure medicine, carefully follow your doctor's instructions about the timing and dosage of your medicine.

Swallow the tablet whole and do not crush, chew, or break it.

Read and carefully follow any Instructions for Use provided with the orally disintegrating or dispersible tablets. Ask your doctor or pharmacist if you do not understand these instructions.

Do not stop using Lamictal ODT suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.

In case of emergency, wear or carry medical identification to let others know you use seizure medication.

Lamictal ODT may affect a drug-screening urine test and you may have false results. Tell the laboratory staff that you use this medicine.

Store at room temperature away from light and moisture.

Is it better to take lamotrigine at night?
You should take lamotrigine at night if it makes you sleepy and if you are prescribed it once a day. But if it doesn’t make you sleepy or if it tends to keep you awake, then take it first thing in the morning.
