Lamotrigine (Lamictal): How This Mood Stabilizer Works and When Telehealth Is Enough

Last updated: August 20, 2026

Lamotrigine, sold as Lamictal, Lamictal CD, Lamictal ODT, and Lamictal XR, is an anticonvulsant used for certain seizures and as maintenance treatment in bipolar I disorder. It is not a rescue medicine for acute mania. This guide covers the boxed rash warning, why titration is slow, how estrogen-containing birth control changes levels, and when a video visit is enough to start or continue care.

TL;DR

• Lamotrigine is an anticonvulsant. Immediate-release and ODT/chewable forms treat seizures (including Lennox-Gastaut) and help delay depression, mania, and other mood episodes in bipolar I. Extended-release tablets are for seizures with other medicines. It has not been shown to treat an acute mood episode on its own. See MedlinePlus and DailyMed.
• Boxed warning: life-threatening rashes, including Stevens-Johnson syndrome and toxic epidermal necrolysis. Risk is higher in children than adults, with valproate, and if you start too high or titrate too fast. Stop at the first sign of rash unless a clinician is sure it is not the drug. See DailyMed.
• Clinicians start low and raise the dose no faster than every 1 to 2 weeks. Starter kits map the first five weeks. Swallow regular and XR tablets whole. Chewable tablets can be swallowed, chewed, or dissolved. Place ODT on the tongue. See MedlinePlus.
• Valproate raises lamotrigine exposure. Estrogen-containing oral contraceptives can lower lamotrigine and lamotrigine can reduce hormonal contraceptive effect; backup contraception is often needed. Dose changes are common when you start or stop those pills. See MedlinePlus and DailyMed.
• Do not restart after a rash without a clinician. If you stop, taper over at least 2 weeks (about 50% per week) unless a rash or other emergency requires an abrupt stop. Sudden stop can trigger seizures. See DailyMed and MedlinePlus.
• Medicare behavioral telehealth in the home is permanent. The extra in-person visit rule is waived through December 31, 2027. See HHS telehealth policy.
• Klarity Health connects you with 2,000+ licensed providers. Coverage may vary by plan. Verify benefits before you book.

What is lamotrigine (Lamictal)?

MedlinePlus classifies lamotrigine as an anticonvulsant. It decreases abnormal electrical activity in the brain. Brand names include Lamictal, Lamictal CD, Lamictal ODT, and Lamictal XR.

Immediate-release, chewable, and ODT forms are used alone or with other medicines for seizures, including Lennox-Gastaut syndrome, and to increase the time between mood episodes in bipolar I disorder. Extended-release tablets are used with other medicines for certain seizures. MedlinePlus states lamotrigine has not been shown to work when people are already in an episode of depression or mania, so other medicines are needed for those acute periods.

DailyMed lists bipolar I maintenance to delay mood episodes after standard therapy for an acute episode. It does not recommend lamotrigine for acute manic or mixed episodes. Effectiveness in acute mood treatment is not established on that ODT label.

NAMI describes lamotrigine as a mood stabilizer approved for bipolar disorder. See NAMI on lamotrigine (Lamictal).

How it works

Lamotrigine is not an SSRI, SNRI, or benzodiazepine. MedlinePlus frames it as an anticonvulsant that lowers abnormal brain electrical activity. That same mechanism is why clinicians use it both for epilepsy and as bipolar I maintenance, not as a same-day mood rescue.

It does not replace lithium, antipsychotics, or antidepressants when those are needed for an acute episode. A licensed clinician decides the mix after a history that covers seizures, mania, depression, rash history, heart rhythm, liver and kidney function, pregnancy plans, and every medicine you take.

Who it is for

DailyMed indications include:

• Adjunctive epilepsy care from age 2: partial-onset seizures, primary generalized tonic-clonic seizures, and generalized seizures of Lennox-Gastaut syndrome.
• Conversion to monotherapy from age 16 in partial-onset seizures when the person is on carbamazepine, phenytoin, phenobarbital, primidone, or valproate as the single AED.
• Bipolar I maintenance to delay mood episodes after standard therapy for an acute episode.

MedlinePlus asks you to tell a clinician about prior rash on lamotrigine or other epilepsy medicines, allergy to epilepsy drugs, autoimmune disease such as lupus, blood disorders, depression or suicidal thoughts, heart failure or irregular rhythms, kidney or liver disease, ascites, pregnancy, and breastfeeding. Infants who nurse may get the drug in milk; watch for unusual sleepiness, interrupted breathing, or poor sucking.

Lamotrigine may make you drowsy or dizzy. Do not drive until you know how it affects you.

Dosing and how to take it

DailyMed states dosing depends on concomitant medicines, indication, and age. Do not exceed the recommended starting dose or the escalation schedule. That rule exists because rash risk rises when titration is too fast.

MedlinePlus: your clinician starts low and increases no more than once every 1 to 2 weeks. The first doses may come in a starter kit for the first 5 weeks. Take it exactly as prescribed. Do not take more, less, or more often than directed.

How to take it (MedlinePlus):

• Regular tablets and extended-release tablets: swallow whole. Do not split, chew, or crush.
• Chewable dispersible tablets: swallow whole, chew (then a small amount of water or diluted juice), or dissolve in 1 teaspoon (5 mL) of water or diluted juice, wait 1 minute, swirl, and drink all of it. Do not split one tablet across doses.
• ODT: place on the tongue, let it dissolve, swallow with or without water.
• DailyMed ODT strengths: 25 mg, 50 mg, 100 mg, and 200 mg.

If you miss a dose, take it when you remember unless it is almost time for the next dose. Do not double up. If you stop for any reason, do not restart without talking to your clinician. DailyMed: do not restart in people who stopped because of rash unless benefits clearly outweigh risks.

Discontinuation (DailyMed): taper over at least 2 weeks, about a 50% reduction per week, unless a rash or other urgent problem requires a faster stop. MedlinePlus: a sudden stop can trigger seizures.

It may take several weeks to feel the full benefit. Keep taking it even if you feel well, unless a clinician tells you to stop.

The boxed rash warning

DailyMed boxed warning: lamotrigine has caused life-threatening serious rashes, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and rash-related death. The rate of serious rash is greater in pediatric patients than in adults. Extra risk factors include valproate, exceeding the recommended initial dose, and exceeding the recommended dose escalation.

Benign rashes also occur. You cannot tell which rash will become serious. DailyMed: discontinue at the first sign of rash unless the rash is clearly not drug-related.

MedlinePlus: serious rashes usually appear in the first 2 to 8 weeks, but can appear later. Call a clinician immediately for rash; blistering or peeling; hives; itching; or painful sores in the mouth or around the eyes. Children 2 to 17 years are more likely to develop serious rashes than adults. Valproic acid (Depakene) or divalproex (Depakote) with lamotrigine raises serious-rash risk.

Other side effects and safety

Common effects MedlinePlus lists (tell a clinician if they are severe or persist): loss of balance, double or blurred vision, nystagmus, trouble thinking or speaking, headache, drowsiness, dizziness, diarrhea, constipation, loss of appetite, weight loss, heartburn, nausea, vomiting, dry mouth, stomach/back/joint pain, missed or painful periods, vaginal irritation, tremor.

Get urgent care for swelling of the face, throat, tongue, lips, or eyes; trouble swallowing or breathing; hoarseness; seizures that change; headache with fever, stiff neck, light sensitivity, confusion; unusual bleeding or bruising; fever with rash, swollen nodes, yellowing skin or eyes, abdominal pain, bloody urine, chest pain, muscle weakness; signs of infection; racing, skipped, or slow heartbeat, shortness of breath, dizziness, or fainting.

MedlinePlus also flags a small number of people 5 and older (about 1 in 500 in anticonvulsant studies) who became suicidal. Call a clinician for panic, agitation, new or worse irritability, anxiety or depression, dangerous impulses, insomnia, aggression, mania, talk of self-harm, withdrawal, or other sudden mood change. If you or someone else is in crisis, call or text 988.

Overdose symptoms MedlinePlus lists include loss of balance, nystagmus, double vision, more seizures, irregular heartbeat, loss of consciousness, and coma. Poison control: 1-800-222-1222 or poisonhelp.org.

Interactions you should flag

• Valproate / divalproex / valproic acid: higher lamotrigine levels and higher serious-rash risk. Dose schedules are slower and lower. See MedlinePlus and DailyMed.
• Estrogen-containing oral contraceptives: DailyMed says most people need maintenance-dose changes when they start or stop these pills. MedlinePlus: lamotrigine may decrease hormonal contraceptive effectiveness (pills, patches, rings, injections). Use another method to prevent pregnancy and talk with your clinician.
• Enzyme-inducing AEDs such as carbamazepine, phenytoin, phenobarbital, and primidone: these change conversion-to-monotherapy tables on DailyMed. Tell your clinician every AED you take.
• Look-alike names: MedlinePlus warns other medicines have names similar to the brand. Confirm the tablets against the pictures in the Medication Guide.

Bring a full list of prescriptions, OTC products, vitamins, and herbals to every visit.

When telehealth is enough

A video visit can cover history, prior rash, current AEDs and contraceptives, mood and seizure pattern, and a titration plan. It cannot replace an ER visit for a spreading rash, blistering, trouble breathing, new severe headache with fever and stiff neck, or a seizure emergency.

Lamotrigine is not a controlled substance on the labels retrieved for this article, which simplifies e-prescribing compared with stimulants. Rash monitoring still needs a clear plan: who you call, when you stop the drug, and when you go in person.

HHS: Medicare patients can permanently receive behavioral/mental telehealth in the home, with no geographic originating-site restriction, including audio-only when needed. The extra in-person visit within six months of an initial behavioral telehealth service, and annually after that, is not required through December 31, 2027.

FAQ

Is lamotrigine an antidepressant?

It is an anticonvulsant used as bipolar I maintenance to delay mood episodes. MedlinePlus says it has not been shown to treat an actual episode of depression or mania by itself.

Why is the dose so slow?

Serious rash risk rises if you start too high or escalate too fast, especially with valproate and in children. MedlinePlus: increase no more than every 1 to 2 weeks.

What should I do if I get a rash?

Contact your clinician immediately. DailyMed: stop at the first sign of rash unless it is clearly not the drug. Do not restart after a drug rash unless a clinician decides benefits outweigh risks.

Can I take lamotrigine with birth control pills?

Often yes, but levels and pregnancy protection can both change. MedlinePlus: use another contraceptive method. DailyMed: expect dose adjustments when you start or stop estrogen-containing pills.

Can a telehealth clinician prescribe lamotrigine?

Many licensed prescribers can, after a history and a titration plan. A spreading or blistering rash needs in-person or emergency care, not a routine follow-up video visit.
