Lamictal® Tablets for Epilepsy and Bipolar I Disorder

Lamotrigine is a prescription anticonvulsant and mood stabilizer. It helps reduce seizures and supports maintenance treatment in bipolar I disorder. This page explains approved uses, safety basics, and how to access it with US delivery from Canada, even without insurance.

Lamictal® contains lamotrigine, which modulates neuronal firing. It primarily blocks voltage-sensitive sodium channels and is thought to inhibit glutamate release. By stabilizing neuronal membranes, this medicine can help reduce seizure frequency. In bipolar I disorder, it helps delay the time to mood episodes during maintenance treatment. Use follows the approved labeling and your prescriber’s guidance.

This treatment is available as immediate-release tablets, extended-release tablets, and orally disintegrating tablets. Chewable-dispersible options exist for certain patients when appropriate. Selection of form depends on diagnosis, concomitant medicines, and individual tolerability.

Who It’s For

Lamictal is indicated for seizure control in focal (partial-onset) seizures, primary generalized tonic-clonic seizures, and as adjunctive therapy in Lennox-Gastaut syndrome. It is also approved for maintenance treatment of bipolar I disorder to help delay mood episodes. Learn more about these conditions in our resources on Epilepsy, Seizures, and Bipolar Disorder.

Patients with a history of hypersensitivity to lamotrigine or past serious rash with this medicine should avoid re-exposure. Use caution in hepatic impairment, renal impairment, and in those with risk factors for severe skin reactions. Safety in pregnancy and lactation requires careful assessment by a healthcare professional.

Dosage and Usage

Lamictal is typically started with a gradual titration schedule. The exact plan varies based on age, indication, and interacting medicines such as valproate or enzyme inducers. Follow the official label and your prescriber’s instructions precisely.

Immediate-release tablets may be taken with or without food. Extended-release tablets should be swallowed whole. Orally disintegrating tablets can be placed on the tongue to dissolve, or dispersed in a small amount of water as directed. Do not abruptly stop this therapy without medical guidance, as seizure risk can increase.

Strengths and Forms

Common presentations include immediate-release tablets, orally disintegrating tablets, chewable-dispersible tablets, and extended-release tablets. Widely published strengths include 25 mg, 50 mg, 100 mg, 150 mg, and 200 mg for immediate-release; extended-release options vary by market. Availability can differ by pharmacy and jurisdiction.

Missed Dose and Timing

If a dose is missed, take it when remembered unless it is close to the next scheduled dose. If it is nearly time for the next dose, skip the missed dose and resume the regular schedule. Do not double the dose. If several days are missed, consult the prescriber before restarting, because re-titration may be needed to reduce rash risk.

Storage and Travel Basics

Store tablets at room temperature in a dry place, away from direct heat and humidity. Keep the bottle or blister pack closed and out of reach of children and pets. For travel, carry your medicine in the original labeled container. Keep it with your carry-on, and avoid leaving tablets in a hot car. Bring a copy of your prescription when crossing borders or passing through security.

Benefits

This medicine can reduce seizure frequency and improve seizure control when used as indicated. In bipolar I disorder, it helps delay mood episodes during maintenance. Multiple formulations support individualized regimens. Once-daily extended-release options may simplify routines for some patients. Generic lamotrigine availability can improve access across care settings.

Side Effects and Safety

• Headache or dizziness
• Nausea, vomiting, or stomach upset
• Sleepiness or insomnia
• Rash or itching
• Tremor
• Blurred or double vision
• Back pain or fatigue

Serious but less common risks include severe skin reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis, DRESS, hemophagocytic lymphohistiocytosis, aseptic meningitis, blood dyscrasias, and suicidal thoughts or behaviors. Seek urgent care for rash with fever, mucosal lesions, swollen lymph nodes, flu-like symptoms, or other systemic signs. Report mood or behavior changes promptly.

Drug Interactions and Cautions

Valproate can increase lamotrigine exposure; enzyme-inducing antiepileptics such as carbamazepine, phenytoin, phenobarbital, and primidone may decrease levels. Estrogen-containing oral contraceptives can affect lamotrigine concentrations; dose adjustments may be needed under medical supervision. Alcohol and sedatives can add to central nervous system effects. Review all medicines, including over-the-counter products and supplements, with a healthcare professional. Use careful monitoring when switching regimens or adding interacting therapies.

What to Expect Over Time

Lamictal usually requires a gradual dose build to support tolerability. Patients may notice changes in seizure control over time as the maintenance dose is reached. In bipolar I disorder, the treatment aims to help maintain stability between episodes. Keep a symptom or seizure diary to share with the prescriber. Adherence, consistent timing, and interaction checks can support long-term outcomes.

Some patients explore lifestyle measures alongside therapy. For example, selected patients with epilepsy may discuss dietary approaches with clinicians. See our article on the Ketogenic Diet for general background.

Compare With Alternatives

Other antiepileptic options may be considered based on seizure type, comorbidities, and tolerability. Common alternatives include Gabapentin and Levetiracetam. Each medicine has distinct interactions and adverse effect profiles. The prescriber will match the therapy to the clinical picture, medical history, and patient preferences.

Patient Suitability and Cost-Saving Tips

Not all patients are candidates for this therapy. Those with prior serious rash from lamotrigine should avoid rechallenge. Caution is needed with hepatic or renal impairment, and when multiple interacting drugs are used. Discuss plans for pregnancy, as serum levels and monitoring needs can change.

To manage costs, consider multi-month fills when feasible, set refill reminders, and use generic lamotrigine when appropriate. Patients paying cash sometimes seek coupons or pharmacy options tailored to their budget. Lamotrigine pay out of pocket scenarios benefit from comparing options and coordinating with the prescriber on form and quantity.

Questions to Ask Your Clinician

• Primary goal: seizure reduction, mood stabilization, or both?
• Which formulation best suits my regimen and other medicines?
• What signs of serious rash or reaction should prompt urgent care?
• How might valproate or enzyme inducers affect my plan?
• Will hormonal contraceptives require dose monitoring or changes?
• What is the plan if I miss several doses?
