What Lamictal® Is and How It Works
Lamictal (lamotrigine) is an oral anticonvulsant and mood stabilizer used for epilepsy and for maintenance treatment of bipolar I disorder. It helps reduce abnormal brain electrical activity by blocking voltage‑sensitive sodium channels and modulating glutamate release. Indications include partial‑onset and primary generalized tonic‑clonic seizures, seizures associated with Lennox‑Gastaut syndrome, and the prevention of mood episodes in bipolar I disorder.

Lamotrigine is taken by mouth as immediate‑release tablets, chewable/dispersible tablets, orally disintegrating tablets, or extended‑release tablets. Dosing is individualized and titrated slowly to lower the risk of serious rash. Frequency is typically once or twice daily, depending on formulation, age, and other medicines.
Dosage and Usage
Follow the prescriber’s schedule closely, as titration depends on age, indication, and interacting medicines (for example, valproate increases lamotrigine levels; enzyme‑inducing antiepileptics may lower them). General principles:
- Initiation usually begins with a low daily dose. Increase every 1–2 weeks as directed to reduce rash risk.
- Typical maintenance in bipolar I disorder is often 100–200 mg/day in divided or once‑daily dosing, depending on formulation.
- For epilepsy, maintenance can range higher (for example, 200–400 mg/day) and varies with co‑administered antiepileptic drugs.
- Extended‑release tablets are taken once daily and should not be crushed or chewed.
- Chewable/dispersible tablets may be chewed or dispersed in water as labeled.
- If treatment is interrupted for more than several days, re‑titration is usually required; consult the prescriber before restarting.
- If a single dose is missed, take it when remembered unless it is close to the next dose. Do not double doses.
Storage and travel tips:
- Store tablets at room temperature, 20–25°C (68–77°F), in a dry place.
- Keep in the original blister or bottle to protect from moisture.
- When traveling, carry the medication in your hand luggage with a copy of the prescription.
- Avoid leaving tablets in a hot car or near direct heat sources.
- Keep out of reach of children and pets.
Benefits and Savings
Lamotrigine helps reduce seizure frequency across several seizure types and is effective as maintenance therapy in bipolar I disorder to delay mood episodes. Many patients find it generally weight‑neutral and less sedating than some alternatives, which can support daytime functioning. Once‑daily extended‑release options may improve convenience.
Many customers save 60–80% versus typical U.S. prices when ordering through CanadianInsulin. Generic lamotrigine offers additional value while maintaining the same active ingredient and strength.

Side Effects and Safety
- Dizziness or unsteadiness
- Headache
- Nausea, vomiting, or stomach upset
- Blurred or double vision
- Sleepiness or insomnia
- Tremor
- Rash
- Back pain or fatigue
Serious reactions can occur. Life‑threatening skin rashes, including Stevens‑Johnson syndrome and toxic epidermal necrolysis, are rare but require urgent care. Other warnings include hypersensitivity reactions such as DRESS, hemophagocytic lymphohistiocytosis (HLH), blood dyscrasias, suicidal thoughts and behaviors, aseptic meningitis, and serious drug interactions (notably with valproate). Seek immediate medical attention for rash, fever, swollen lymph nodes, or organ symptoms.
Onset Time
Benefits depend on titration and the target dose. Seizure control may improve as doses are increased over the first 2–6 weeks, with fuller effects after maintenance dosing is reached. For bipolar I maintenance, stabilizing effects generally emerge over several weeks and continue to build as the regimen reaches the prescribed maintenance dose.
Compare With Alternatives
Several options may be considered based on seizure type, tolerability, and comorbidities. Lyrica® (pregabalin) is another anticonvulsant used for partial‑onset seizures and neuropathic pain. It may cause more sedation and weight gain compared with lamotrigine. See Lyrica for details.
Gabapentin is also used in partial‑onset seizures and neuropathic pain. It often requires three‑times‑daily dosing and can cause dizziness and drowsiness. Compare options on Gabapentin to discuss with a clinician.
For those who have trouble swallowing tablets, Lamictal chewable/dispersible or orally disintegrating tablets may be considered as alternative formulations. Choice among these depends on age, indication, dosing schedule, and patient preference.
Combination Therapy
- With valproate: lower lamotrigine doses are typically required; the combination increases lamotrigine levels and rash risk.
- With enzyme‑inducing antiepileptics (for example, carbamazepine, phenytoin, phenobarbital, primidone): higher lamotrigine maintenance doses may be needed.
- With lithium for bipolar maintenance: used under prescriber supervision for complementary mood stabilization.
- With antidepressants (for example, SSRIs/SNRIs, bupropion): may be combined for mood management; monitor for interactions and seizure risk with bupropion.
- Hormonal contraceptives containing estrogen can lower lamotrigine levels; dose adjustments and monitoring may be required.
Patient Suitability and Cost‑Saving Tips
Lamotrigine is used in adults and in pediatric patients for specific seizure types. In bipolar I disorder, it is indicated for maintenance treatment to help delay mood episodes and is not established for acute mania or acute bipolar depression. People with a history of serious rash to lamotrigine or its components should not take it.
Discuss pregnancy and breastfeeding plans with a clinician, as dose adjustments and monitoring may be needed. Report new rashes, fever, or systemic symptoms promptly. Alcohol or sedatives may worsen dizziness or drowsiness.
To reduce costs, consider generic lamotrigine when appropriate, request a multi‑month supply if clinically suitable, and plan refills ahead to avoid gaps during titration. CanadianInsulin offers transparent selection and value‑focused pricing, and you can combine items in one shipment for convenience.

What is Lamictal used for?
Lamictal (lamotrigine) is prescribed for epilepsy, including partial‑onset seizures, primary generalized tonic‑clonic seizures, and seizures of Lennox‑Gastaut syndrome. It is also approved for maintenance treatment of bipolar I disorder to help delay mood episodes. It is not established for treating acute mania or acute bipolar depression.
How long does Lamictal take to work?
Effects build gradually as doses increase during titration. Many patients notice seizure benefits within 2–6 weeks, with fuller control after reaching the maintenance dose. For bipolar I maintenance, stabilization develops over several weeks and continues as the prescribed dose is maintained.
What strengths are available (25 mg, 50 mg, 100 mg, 200 mg)?
Common immediate‑release tablet strengths include 25 mg, 50 mg, 100 mg, and 200 mg. Chewable/dispersible tablets and orally disintegrating tablets exist for patients who need alternative forms. Extended‑release tablets allow once‑daily dosing. Strength and formulation are selected by the prescriber for each indication.
Can Lamictal help with depression or anxiety?
Lamotrigine is approved to maintain stability in bipolar I disorder and to delay mood episodes, including depressive episodes. It is not approved for unipolar major depression or generalized anxiety disorder. Treatment choices for depression or anxiety should be individualized and guided by a healthcare professional.
Can Lamictal be taken with Wellbutrin or other antidepressants?
Lamotrigine may be combined with antidepressants under medical supervision. Bupropion (Wellbutrin) can lower the seizure threshold, so clinicians weigh risks and benefits, especially in people with seizure disorders. No major metabolic interaction is expected, but monitoring for side effects and clinical response is recommended.
Are serious rashes common with Lamictal?
Serious rashes such as Stevens‑Johnson syndrome and toxic epidermal necrolysis are rare but can be life‑threatening. Risk is higher with rapid dose escalation, use with valproate, or in younger children. Any rash with fever or systemic symptoms needs urgent medical evaluation and the medication is typically stopped.
How much does Lamictal cost through CanadianInsulin?
Pricing varies by strength, brand versus generic lamotrigine, and quantity. Many customers save 60–80% compared with typical U.S. pharmacy prices. Check current options on the product page, select the needed strength, and proceed with a valid prescription for verified fulfillment.
