Lamictal® Tablets for Epilepsy and Bipolar Disorder

Lamictal is a prescription antiepileptic used to help control seizures and maintain stability in bipolar I disorder. This page explains what it is, how it works, and important safety points so you can discuss therapy confidently with your clinician. We support US delivery from Canada and options for those paying without insurance.

What Lamictal Is and How It Works

Lamictal® contains lamotrigine, a medicine in the anticonvulsant class. It helps stabilize brain activity by blocking voltage-sensitive sodium channels and modulating glutamate release. Many people start low and increase gradually to reduce the risk of rash; for example, some plans begin at Lamotrigine 25 mg before careful titration. YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This medicine is used for seizure control in certain epilepsy types and for maintenance treatment of bipolar I disorder to delay mood episodes. It is not indicated for acute mania or acute bipolar depression. Do not change your dose or schedule without guidance from your healthcare professional.

Who It’s For

This treatment is approved for adults and certain pediatric patients with epilepsy, including partial-onset seizures, primary generalized tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome. It is also used in adults for maintenance therapy in bipolar I disorder to help delay the time to mood episodes. It is not a cure for epilepsy or a fast-acting option for acute manic or depressive episodes.

People with a history of severe rash from this drug, known hypersensitivity to any component, or serious reactions like Stevens-Johnson syndrome should avoid re-exposure. Discuss liver or kidney problems, pregnancy plans, and all medicines you take with your clinician. Learn more about seizure care in our condition pages for Epilepsy and Bipolar Disorder.

Dosage and Usage

Follow your prescriber’s schedule exactly. Titration is gradual, especially at the start, to lower the chance of serious rash. Your plan may differ if you also take valproate, carbamazepine, phenytoin, phenobarbital, primidone, or certain other medicines. Do not abruptly stop this therapy, as doing so may increase seizure risk.

Immediate-release tablets are usually taken once or twice daily as directed. Extended-release tablets are typically taken once daily; they must be swallowed whole. Chewable dispersible tablets may be chewed or dispersed in a small amount of liquid, then swallowed promptly. If switching dosage forms, your prescriber will guide the transition. Always read the Patient Information and Medication Guide.

Strengths and Forms

Availability can vary by manufacturer and country. Common presentations include immediate-release tablets, chewable dispersible tablets for dose flexibility, and an extended-release option for once-daily convenience. The extended-release line is marketed as Lamictal ER. Typical tablet strengths include 25 mg, 50 mg, 100 mg, 150 mg, and 200 mg. Chewable dispersible products may be available in lower strengths. Exact options may differ by supplier; refer to the product listing for what we currently stock.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to the next dose. If it is almost time for your next scheduled dose, skip the missed one and resume your regular schedule. Do not double up doses. If you miss several days, speak with your prescriber before restarting because titration may need to be re-established to reduce rash risk.

Storage and Travel Basics

Store tablets at room temperature in a dry place, in the original container with the label intact, and away from children and pets. Keep the container securely closed and protect it from excess heat and moisture. For trips, carry this medicine in your hand luggage with a copy of your prescription. Use a daily pill organizer only if it will not expose tablets to humidity. When crossing time zones, ask your clinician how to adjust timing.

Benefits

This therapy can help reduce seizure frequency when used as directed and may delay mood episodes in bipolar I disorder maintenance. Many patients appreciate once-daily extended-release options and the flexibility of chewable dispersible tablets for tailored dosing. Consistent use, careful titration, and routine follow-up are key to sustained control.

Side Effects and Safety

• Common: dizziness, headache, nausea, sleepiness, insomnia, blurred or double vision
• Other effects: tremor, ataxia, rash, vomiting, diarrhea, back pain

Serious skin reactions can occur, including Stevens-Johnson syndrome and toxic epidermal necrolysis. A widespread rash, blistering, mouth sores, fever, swollen glands, or flu-like symptoms need urgent evaluation. Rare risks include hypersensitivity reactions, blood abnormalities, aseptic meningitis, and hemophagocytic lymphohistiocytosis. Report new or worsening mood or behavior changes, including suicidal thoughts. Do not restart after a serious drug-related rash unless a specialist advises it.

Drug Interactions and Cautions

Valproate can increase levels of this medicine, while enzyme inducers such as carbamazepine, phenytoin, phenobarbital, and primidone may decrease levels. Estrogen-containing oral contraceptives can lower lamotrigine concentrations; your prescriber may monitor and adjust therapy as needed. Heavy alcohol use can worsen dizziness or coordination. Tell your clinician about all medicines, supplements, and herbal products you use.

What to Expect Over Time

Effects build with steady use after titration. For epilepsy, your clinician will assess seizure control over follow-up visits and may adjust your regimen. For bipolar I maintenance, the goal is to help extend stability between mood episodes. Keep a simple diary for doses, moods, and seizure activity to support discussions at appointments.

Compare With Alternatives

Many patients use generic lamotrigine, which contains the same active ingredient as the brand. See our product page for Lamotrigine to explore options your prescriber may consider. Another commonly used antiepileptic is levetiracetam; some adults benefit from this alternative when appropriate. Learn more on our listing for Keppra. Your clinician will choose based on your diagnosis, other medicines, and response history.

Availability and Substitutions

Supply, pack size, and manufacturers can change. If your strength or form is not listed, your prescriber may recommend a suitable alternative. Generic drug for Lamictal options may be appropriate for many patients; your clinician will decide if substitution is suitable for you. For background on equivalence, see our article Generics Vs Brand.

Patient Suitability and Cost-Saving Tips

This medicine may fit adults with focal or generalized seizure types specified on the label and adults needing bipolar I maintenance. It may not suit those with prior severe rash to this drug or certain allergies. If you manage a chronic condition, ask about multi-month supplies to reduce pharmacy visits. Consider generics when appropriate, and set refill reminders so you do not run out. Explore related topics under Mental Health to learn about supportive care.

Questions to Ask Your Clinician

• Starting plan: How will my dose be titrated to minimize rash risk?
• Other medicines: Do my current drugs affect lamotrigine levels?
• Form choice: Should I use immediate-release or extended-release tablets?
• Monitoring: What symptoms mean I should call or seek urgent care?
• Family planning: How is therapy managed during pregnancy or breastfeeding?
