Lamictal is a prescription antiepileptic and mood-stabilizing medicine used to prevent seizures and to help maintain long-term stability in bipolar disorder, especially bipolar I. It works by stabilizing overactive brain signaling, particularly by modulating voltage-gated sodium channels and limiting glutamate release. When started and increased slowly, Lamictal is generally well tolerated, but it carries a boxed warning for rare, serious rashes like Stevens-Johnson syndrome. Dosing is individualized and titrated gradually to minimize side effects. Patients should review interactions (for example, with valproate or oral contraceptives) and discuss pregnancy or breastfeeding plans with a clinician.
Lamictal is widely used for epilepsy and bipolar disorder. In epilepsy, it can be prescribed as monotherapy or adjunctive therapy to reduce partial-onset seizures, primary generalized tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome. For mental health, lamotrigine is a mood stabilizer indicated for the maintenance treatment of bipolar I disorder, where it helps reduce the likelihood of depressive episode recurrence. Unlike some mood stabilizers, it is not typically used for acute mania; its strength is in the prevention of bipolar depression. Clinicians value lamotrigine for its generally favorable cognitive profile relative to some older antiepileptic drugs and for its weight-neutral tendency in many patients.
Mechanistically, lamotrigine modulates voltage-sensitive sodium channels in neurons, dampening pathologic hyperexcitability and reducing presynaptic release of excitatory neurotransmitters such as glutamate and aspartate. This stabilizing effect is thought to underpin both its antiepileptic and mood-stabilizing benefits. Because mood and seizure control often hinge on consistent blood levels, adherence and a careful, individualized titration plan are essential to maximize efficacy and safety.
Lamictal dosing is highly individualized and depends on the indication (seizure control versus bipolar maintenance), age, concomitant medications, and clinical response. A universal principle is to start low and increase slowly. Gradual titration helps minimize the risk of serious rash and other side effects. Your prescriber will set a schedule and adjust it based on your tolerability and goals.
For adults with bipolar I maintenance therapy, a common monotherapy approach begins at low doses and titrates over several weeks to a typical target of around 200 mg per day. When lamotrigine is combined with certain other medicines, the target dose may be lower or higher: coadministration with valproate (which raises lamotrigine levels) often calls for a lower target, whereas enzyme-inducing antiepileptics (such as carbamazepine, phenytoin, phenobarbital, or primidone) may necessitate a higher target because they reduce lamotrigine levels. These adjustments should always be guided by a clinician.
For epilepsy, titration schedules vary depending on whether lamotrigine is used alone or alongside other antiepileptic drugs. When used with valproate, slower dose increases are required. When used with enzyme inducers, higher final doses may be needed. Because these regimens can be complex, patients should adhere to the exact plan provided by their healthcare professional and the product label.
Lamictal can be taken with or without food. Try to take it at the same time each day to maintain steady blood levels. Extended-release formulations are available for once-daily dosing in appropriate patients. Do not change your dose, formulation, or dosing frequency without consulting your clinician, and never restart at a high dose if you have stopped for several days; re-titration is often necessary.
Lamotrigine carries a boxed warning for serious skin reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). The risk is increased by rapid dose escalation, exceeding recommended initial doses, or coadministration with valproate. Seek urgent medical attention for any widespread rash, blistering, mucous membrane involvement, fever, facial swelling, or systemic symptoms. Although most rashes are mild, differentiating early is critical—do not continue the medication if a concerning rash develops until you have medical advice.
Like other antiepileptic drugs, lamotrigine may increase the risk of suicidal thoughts and behaviors in a small percentage of patients. Monitor for new or worsening depression, agitation, anxiety, or unusual mood changes, especially during initiation and dose adjustments, and report concerns promptly.
Rare hypersensitivity reactions such as drug reaction with eosinophilia and systemic symptoms (DRESS), hemophagocytic lymphohistiocytosis (HLH), and aseptic meningitis have been reported. Symptoms can include fever, swollen lymph nodes, organ involvement, severe fatigue, neck stiffness, or persistent headache. Any severe or atypical symptom warrants immediate evaluation.
Pregnancy requires special consideration. Lamotrigine clearance often increases during pregnancy, potentially lowering blood levels and reducing effectiveness; postpartum, levels typically rebound. Therapeutic drug monitoring with dose adjustments is commonly used. Discuss family planning, contraception, and breastfeeding with your clinician; lamotrigine passes into breast milk, and infants should be monitored for sedation or poor feeding. Weigh the benefits of seizure control or mood stabilization against potential risks.
Because lamotrigine can cause dizziness, blurred vision, or incoordination, use caution when driving or operating machinery until you know how the medicine affects you. Avoid abrupt discontinuation, which can precipitate seizures even in patients taking lamotrigine for bipolar disorder.
Lamictal is contraindicated in patients with known hypersensitivity to lamotrigine or any component of the formulation. A history of serious lamotrigine-induced rash or multi-organ hypersensitivity generally precludes re-exposure. Use extreme caution in patients with prior severe cutaneous adverse reactions to other drugs. Dose adjustments may be needed in significant hepatic impairment; careful clinical judgment is essential. As with any antiepileptic, an individualized risk–benefit assessment should guide therapy, especially in populations at higher risk for adverse effects.
Common side effects include dizziness, headache, nausea, vomiting, somnolence or insomnia, fatigue, ataxia (unsteady gait), tremor, blurred or double vision (diplopia), and benign skin rash. Many of these effects lessen as your body adjusts or with dose optimization. Taking the medication consistently and avoiding rapid increases reduces side-effect burden.
Serious but uncommon adverse effects include SJS/TEN, DRESS, HLH, aseptic meningitis, blood dyscrasias, liver dysfunction, and severe hypersensitivity reactions that may involve multiple organ systems. Emergent evaluation is warranted for severe rash, mucosal lesions, high fever, lymphadenopathy, unexplained bruising or bleeding, severe abdominal pain, jaundice, persistent vomiting, confusion, or seizures beyond baseline.
Neuropsychiatric effects can occur, including mood swings, irritability, anxiety, or depressive symptoms; any suicidal ideation requires immediate attention. Visual disturbances and coordination issues may affect fall risk, especially in older adults. Report troublesome side effects—dose adjustments, slower titration, or formulation changes may help.
Valproate (valproic acid/divalproex) significantly increases lamotrigine levels by inhibiting its metabolism; when used together, lower lamotrigine doses and slower titration are required. Conversely, enzyme-inducing antiepileptics such as carbamazepine, phenytoin, phenobarbital, and primidone accelerate lamotrigine clearance, often necessitating higher maintenance doses. Rifampin and some antiretrovirals (e.g., lopinavir/ritonavir) can also alter lamotrigine concentrations; your prescriber may adjust accordingly.
Combined oral contraceptives containing ethinyl estradiol can increase lamotrigine clearance, lowering levels and potentially reducing efficacy—patients may notice symptom changes during the active pill weeks versus the hormone-free interval. Monitoring and dose adjustments may be needed when starting or stopping hormonal contraception. Progestin-only methods can have variable effects; coordinate closely with your clinician.
Other notable interactions include sertraline and other SSRIs causing additive central nervous system effects, and additive sedation with alcohol or CNS depressants. Always provide a complete list of prescription drugs, over-the-counter medicines, vitamins, and herbal supplements (such as St. John’s wort) to your healthcare provider before starting lamotrigine.
If you miss a dose, take it as soon as you remember unless it is close to the time for your next dose. If it is near the next scheduled dose, skip the missed dose and resume your regular schedule. Do not double up to make up for a missed dose. If you miss several days, contact your prescriber before restarting; because lamotrigine relies on gradual titration to reduce rash risk, you may need to reinitiate at a lower dose and retitrate.
Lamotrigine overdose can cause severe dizziness, drowsiness, agitation, ataxia, nystagmus, seizures, vomiting, low blood pressure, cardiac conduction changes, and, rarely, coma. Overdose is a medical emergency. If an overdose is suspected, call local emergency services immediately and contact Poison Control (in the U.S., 1-800-222-1222) for guidance. Care is supportive, with attention to airway, breathing, circulation, and seizure management. Never share your medication, and store it securely to prevent accidental ingestion by children or pets.
Store Lamictal at room temperature, typically 20–25°C (68–77°F), with brief excursions permitted per the product label. Keep tablets in a tightly closed, child-resistant container, protected from moisture and excessive heat. Do not use tablets that are discolored, chipped, or expired. Keep all medications out of reach of children and pets. If your prescription includes blister packs or orally disintegrating tablets, follow the handling instructions to avoid damaging the dosage form.

Lamictal is an anticonvulsant used to prevent seizures in epilepsy and to maintain stability in bipolar I disorder, particularly to delay depressive episodes.
It blocks voltage-gated sodium channels, stabilizes neuronal firing, and reduces glutamate release; its mood-stabilizing effects likely stem from these actions.
Seizure control may improve after several weeks when the target dose is reached; mood benefits often emerge after 4–8 weeks due to slow titration.
A gradual dose increase lowers the risk of serious rashes such as Stevens-Johnson syndrome and toxic epidermal necrolysis.
Headache, dizziness, nausea, sleepiness or insomnia, blurred or double vision, tremor, mild rash, and coordination problems are common and often transient.
A widespread or blistering rash, mouth sores, fever, swollen lymph nodes, facial swelling, severe weakness, liver problems, blood disorders, aseptic meningitis, or suicidal thoughts require immediate evaluation.
Avoid if you had a severe lamotrigine reaction; use caution with liver or kidney disease, prior severe antiepileptic rash, concurrent valproate, pediatric use, or if you cannot adhere to titration.
Valproate raises lamotrigine levels; enzyme inducers like carbamazepine, phenytoin, phenobarbital, primidone, and rifampin lower them; combined oral contraceptives increase clearance; atazanavir/ritonavir and St. John’s wort can alter levels.
Dosing depends on age, indication, and interacting drugs; adults often start at 25 mg daily for 2 weeks, then 50 mg daily for 2 weeks, then 100 mg daily, adjusting to 100–200 mg/day for bipolar and higher for epilepsy; doses are lower with valproate and higher with inducers.
Take it when remembered unless it is close to the next dose; do not double up; if you miss several days, contact your prescriber since you may need to restart titration.
Do not stop suddenly unless you have a severe reaction; taper over at least 2 weeks to reduce seizure risk and mood relapse.
Risk–benefit is individualized; pregnancy increases lamotrigine clearance, often requiring dose adjustments; it appears relatively safer than valproate but is not risk-free; it passes into breast milk, generally compatible with monitoring the infant for rash or sedation.
It is usually weight-neutral and tends to be cognitively gentler than some anticonvulsants, though mild concentration or word-finding issues can occur.
Alcohol can worsen dizziness and sedation and may lower seizure threshold; if you drink, keep it light and consistent, and avoid heavy use.
No routine labs are required; levels can be checked in special cases such as pregnancy, suspected interactions, side effects, or adherence questions.
Yes, especially early in therapy or with rapid dose increases; follow the titration schedule, avoid missed doses, and contact your clinician at the first sign of a new or worsening rash.
Until you know how it affects you, avoid hazardous tasks; dizziness, blurred vision, or sleepiness can impair reaction time.
Estrogen-containing contraceptives can lower lamotrigine levels and cause fluctuations; dose adjustments or alternative contraception may be needed.
Store at room temperature, dry, away from light and moisture, and keep out of reach of children.
FDA-approved generics are considered bioequivalent; if you notice changes when switching products, discuss with your prescriber.
Lamictal is stronger for preventing depressive episodes and is weight-neutral; valproate is better for acute mania but often causes weight gain and is teratogenic.
Lithium excels in mania control and suicide prevention but requires blood level and kidney/thyroid monitoring; lamotrigine helps prevent bipolar depression with fewer labs but has rash risk and slower onset.
Keppra titrates quickly and has minimal interactions but may cause irritability or mood changes; lamotrigine has more interactions yet often has a more favorable behavioral profile and added antidepressant benefits.
Carbamazepine is an enzyme inducer with many interactions and risks hyponatremia and rare blood dyscrasias; lamotrigine avoids enzyme induction and is metabolically gentler but carries serious rash risk.
Oxcarbazepine has fewer interactions than carbamazepine but more hyponatremia; lamotrigine is weight-neutral with strong data in bipolar depression prevention; choice depends on comorbidities and sodium risk.
Topiramate often causes cognitive slowing, paresthesias, and weight loss; lamotrigine is cognitively gentler and weight-neutral but needs slow titration.
Zonisamide may cause weight loss, kidney stones, metabolic acidosis, and sulfonamide-related rash; lamotrigine has better bipolar evidence and fewer kidney/metabolic issues.
Lacosamide titrates faster and can prolong the PR interval; lamotrigine offers antidepressant effects in bipolar maintenance; selection hinges on cardiac status, interactions, and mood needs.
Gabapentin has limited evidence as a mood stabilizer; lamotrigine is evidence-based for bipolar maintenance and is generally preferred for mood stabilization.
Phenytoin is a strong inducer with cosmetic and bone health issues; lamotrigine avoids enzyme induction and is typically better tolerated but requires careful titration due to rash risk.
Lamotrigine is generally considered to carry lower teratogenic risk than valproate, though not risk-free; careful planning, folate supplementation, and monitoring are essential.
Antidepressants can trigger mania and often require a mood stabilizer; lamotrigine reduces depressive relapses with low switch risk but has a slower onset.
XR provides smoother blood levels and once-daily dosing that may improve adherence and reduce peak-related side effects; dosing conversions should be guided by a clinician.
