Q: How does Lamotrigine work?

Mechanism of Action Lamotrigine belongs to a class of drugs known as antiepileptics or anticonvulsants. While the exact way it works is not completely understood, researchers believe it helps stabilize the electrical activity of nerve cells in the brain. Stabilizing Nerve Signals The medication works primarily by blocking voltage-sensitive sodium channels in the brain. By doing this, it helps prevent nerve cells from sending repetitive or excessive electrical signals. This stabilization helps to: Reduce Seizures: By preventing overactive electrical bursts, it helps control various types of seizures. Balance Neurotransmitters: It inhibits the release of certain chemicals, such as glutamate, which are responsible for exciting nerve cells. Effect on Mood In the treatment of bipolar disorder, lamotrigine is thought to help delay or prevent mood episodes, such as depression or mania. Although the precise mechanism for mood stabilization is not fully established, it is believed to involve the same stabilization of nerve activity and chemical balance in the brain.

Q: What is the dosage of Lamotrigine and how do I take it?

How to Take Lamotrigine Lamotrigine is available in several oral forms, including standard tablets, chewable dispersible tablets, and orally disintegrating tablets. It is important to follow the specific instructions for the form you have been prescribed: Standard tablets: These should be swallowed whole. Do not crush or chew them, as they may have a bitter taste. Chewable dispersible tablets: These may be swallowed whole, chewed, or mixed into a small amount of water or fruit juice. If chewed, drink a small amount of water or juice afterward to ensure the entire dose is swallowed. Orally disintegrating tablets: Place the tablet on your tongue and allow it to dissolve. It can be swallowed with or without water. You can take this medication with or without food. To help you remember your doses, try to take it at the same time each day. Missed Doses If you miss a dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take two doses at the same time to make up for a missed one. Important Considerations It is common for healthcare providers to start treatment with a low dose and gradually increase it over several weeks. Do not change your dose or stop taking the medication without consulting your doctor, even if you feel well. Stopping the medication suddenly can cause serious health problems, such as increased seizure activity.

Q: Is Lamotrigine safe during pregnancy and breastfeeding?

Pregnancy Deciding whether to continue lamotrigine during pregnancy involves weighing the benefits of controlling seizures or mood symptoms against potential risks to the fetus. Untreated epilepsy or bipolar disorder can pose significant health risks to both the pregnant person and the developing baby. You should not start or stop taking this medication during pregnancy without consulting a healthcare provider. During pregnancy, the body's metabolism changes, which often causes the level of lamotrigine in the blood to decrease. Healthcare providers typically monitor blood levels closely throughout pregnancy and may need to increase the dosage to ensure the medication remains effective. After delivery, the dose may need to be adjusted again as the body returns to its pre-pregnancy state. While some data have investigated a potential link between lamotrigine and birth defects like oral clefts, the evidence is not conclusive. To help monitor the safety of the medication, patients are encouraged to enroll in the North American Antiepileptic Drug Pregnancy Registry. Breastfeeding Lamotrigine passes into breast milk, and nursing infants can be exposed to the medication. While many people continue to take lamotrigine while breastfeeding, it is important to monitor the infant closely for potential side effects. Contact a healthcare provider immediately if a breastfed infant develops any of the following: A skin rash Extreme sleepiness or lethargy Poor sucking or difficulty feeding Difficulty breathing A healthcare provider can help determine the best feeding plan based on your specific medical needs and the health of the infant.

Q: What forms and strengths does Lamotrigine come in?

Lamotrigine is provided in the following oral forms: Immediate-release tablets: Standard tablets intended to be swallowed whole. Chewable dispersible tablets: These may be swallowed whole, chewed, or mixed into a small amount of liquid such as water or fruit juice. Extended-release tablets: These are formulated to release the medication slowly into the body. They must be swallowed whole and should not be crushed, chewed, or broken. Orally disintegrating tablets: These tablets are designed to dissolve quickly on the tongue and can be swallowed with or without water.

Question 11

What is the FDA approval status of Lamotrigine?

Accepted Answer

FDA Approval and Indications

The U.S. Food and Drug Administration (FDA) has approved lamotrigine for the treatment of epilepsy and bipolar I disorder. It is indicated for use in adults and children for various types of seizures and as a maintenance treatment to delay mood episodes in adults with bipolar disorder.

Boxed Warning

Lamotrigine carries a boxed warning for serious and potentially life-threatening skin rashes, including Stevens-Johnson syndrome and toxic epidermal necrolysis. The risk of these reactions is higher in pediatric patients, those taking valproate concurrently, or when the starting dose or dose escalation exceeds recommended levels.

Safety Communications

The FDA has issued several safety alerts regarding lamotrigine:

Heart Rhythm Problems: Studies indicate an increased risk of heart rhythm problems (arrhythmias) in patients with pre-existing heart disease or certain underlying cardiac conditions.
Immune System Reaction: The FDA warned of a rare but serious immune system reaction called hemophagocytic lymphohistiocytosis (HLH), which can cause severe inflammation and lead to hospitalization or death.
Aseptic Meningitis: There is a risk of aseptic meningitis, a non-bacterial inflammation of the membranes covering the brain and spinal cord.

Question 12

What should I know about Lamotrigine and withdrawal?

Accepted Answer

Risks of Abrupt Discontinuation

You should not stop taking lamotrigine without first consulting your doctor, even if you feel well. Stopping the medication suddenly can cause severe health issues, particularly for those being treated for epilepsy. Risks include:

Increased Seizures: Abruptly ending treatment can cause seizures to return or occur more frequently.
Status Epilepticus: In some cases, sudden withdrawal can lead to prolonged seizures that do not stop, which is a medical emergency.
Return of Symptoms: For those taking lamotrigine for bipolar disorder, stopping the medication may lead to a recurrence of mood symptoms.

The Tapering Process

To safely discontinue lamotrigine, healthcare providers typically recommend a gradual reduction in dosage. This tapering process usually occurs over a period of at least two weeks, though your doctor may suggest a longer timeframe based on your specific medical history and current dosage.

Restarting Treatment

If you stop taking lamotrigine for more than a few days, you should not restart it at your previous dose. Contact your healthcare provider immediately for instructions. Because of the risk of developing a serious and potentially life-threatening skin rash, you will likely need to restart the medication at a very low dose and gradually increase it again, following the initial titration schedule.
