Lamictal® Chewable Tablets for Epilepsy and Bipolar Disorder

What Lamictal® Is and How It Works

Lamictal® chewable dispersible tablets contain lamotrigine, an anticonvulsant used for seizure control and for maintenance treatment in bipolar I disorder. This page helps compare options, learn proper use, and order with US delivery from Canada. Many patients look for lower costs, including those paying without insurance.

Lamotrigine is thought to stabilize neuronal membranes by blocking voltage‑sensitive sodium channels. This action helps reduce excessive glutamate release and lowers seizure activity. In bipolar I disorder, the exact mechanism is not fully understood, but it helps delay the time to mood episodes when used for maintenance. It is not approved for treating acute mania or acute bipolar depression.

Who Lamictal® Is For

Lamotrigine is indicated for epilepsy, including partial‑onset seizures, primary generalized tonic‑clonic seizures, and seizures associated with Lennox‑Gastaut syndrome. It can be used as monotherapy or as adjunctive therapy with other antiepileptic drugs. It is also approved for maintenance therapy in adults with bipolar I disorder to delay mood episodes. For condition overviews, see Epilepsy and Bipolar Disorder.

People with a history of serious hypersensitivity to lamotrigine should avoid this medicine. The risk of serious rash increases with high starting doses, rapid titration, and use with valproate. Use caution in hepatic impairment and in patients with a history of severe skin reactions. Do not start or stop therapy abruptly without medical guidance, as seizures or mood symptoms may worsen.

Dosage and Usage

Dosing depends on age, indication, and co‑administered medicines. Follow the official label and your prescriber’s plan. Typical adult schedules are summarized at a high level:

• Without valproate and without enzyme inducers (such as carbamazepine, phenytoin, phenobarbital, primidone): start low, often 25 mg once daily for 2 weeks, then 50 mg once daily for 2 weeks, then increase by 50 mg to 100 mg every 1 to 2 weeks to a usual maintenance range. For bipolar maintenance, many adults stabilize between 100 mg and 200 mg daily. For epilepsy, maintenance may be higher.
• With valproate: because valproate raises lamotrigine levels, start even lower, commonly 25 mg every other day for 2 weeks, then 25 mg once daily for 2 weeks, increasing gradually per label. Maintenance doses are typically lower than when used without valproate.
• With enzyme inducers but without valproate: clearance is increased. Initial and maintenance doses are often higher than standard. Titration still follows gradual weekly steps.

Chewable dispersible tablets may be chewed, or dispersed in a small amount of water or diluted fruit juice, and swallowed immediately. Consistency matters. Take doses at the same times each day as directed. If therapy is interrupted for several days, re‑titration may be needed. Defer to the official label for detailed schedules.

Strengths and Forms

Chewable dispersible Lamictal tablets are commonly available in these strengths:

• 2 mg
• 5 mg
• 25 mg

Other lamotrigine forms exist, including standard tablets and orally disintegrating tablets, in additional strengths. Availability may vary by manufacturer and country.

Missed Dose and Timing

If a dose is missed, take it when remembered unless it is close to the next dose. If it is near the next scheduled time, skip the missed dose. Do not double up. Keeping a daily schedule and reminders can help prevent missed doses. If multiple doses are missed, contact a clinician because restarting may require a new titration plan.

Storage and Travel Basics

Store tablets at room temperature and protect from moisture and light. Keep in the original container with the label intact. For travel, carry enough doses in hand luggage and a copy of the prescription. Use a pill organizer only if it stays dry and protected from heat. Do not freeze or expose to excessive temperatures.

Benefits

• Helps reduce frequency of focal and generalized tonic‑clonic seizures.
• Approved for maintenance in bipolar I disorder to delay mood episodes.
• Generally weight‑neutral and not typically sedating for many patients.
• Chewable dispersible format supports pediatric use and swallowing difficulties.
• Flexible titration to find an individualized maintenance dose.

Side Effects and Safety

• Common: dizziness, headache, nausea, vomiting, sleepiness, trouble concentrating, blurred or double vision, coordination issues, tremor, back pain.
• Less common: insomnia, dry mouth, abdominal pain, rash, anxiety, irritability.

Serious reactions can include severe rash such as Stevens‑Johnson syndrome or toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), hemophagocytic lymphohistiocytosis (HLH), aseptic meningitis, blood dyscrasias, and suicidal thoughts or behavior. Seek urgent care for rash with blistering, peeling, fever, swollen lymph nodes, mouth sores, yellowing of skin or eyes, unusual bleeding, or new severe mood or behavior changes.

Drug Interactions and Cautions

• Valproate increases lamotrigine levels; lower starting and maintenance doses are used.
• Enzyme inducers such as carbamazepine, phenytoin, phenobarbital, and primidone may lower lamotrigine levels; higher doses may be required.
• Combined hormonal contraceptives can increase lamotrigine clearance; levels may fluctuate with the pill‑free week.
• Other antiepileptic drugs may interact; review all medicines, including over‑the‑counter and herbal products.
• Avoid abrupt discontinuation unless medically necessary.
• Use caution in hepatic impairment and during pregnancy or breastfeeding; weigh risks and benefits with a clinician.

What to Expect Over Time

Titration is gradual to reduce the risk of rash. Seizure control often improves over several weeks as the dose reaches maintenance. In bipolar I disorder, benefits appear during maintenance and help extend the time between mood episodes. If response is incomplete, clinicians may adjust the regimen or add adjunctive therapies. Lifestyle measures can complement therapy; for some patients with epilepsy, dietary approaches may be discussed. Learn more in Epilepsy and the Ketogenic Diet.

Compare With Alternatives

For epilepsy, a common alternative is Levetiracetam, which has a different interaction profile and titration approach. For bipolar disorder, some patients may use an atypical antipsychotic such as Latuda® for specific phases under clinician guidance. For background on antipsychotic roles in mood treatment, see Abilify Uses.

Availability and Substitutions

Supply can vary by strength and manufacturer. If a specific strength is unavailable, a prescriber may adjust the plan or recommend an appropriate alternative. Pharmacists may dispense a therapeutically equivalent generic lamotrigine when permitted by your prescription and local regulations.

Patient Suitability and Cost Saving Tips

Lamotrigine may suit patients who need seizure control or bipolar I maintenance and prefer a weight‑neutral, generally non‑sedating option. It may not suit those with prior serious lamotrigine rash or severe hypersensitivity. Extra caution is used with valproate co‑therapy and during pregnancy.

• Ask about multi‑month supplies to reduce per‑fill costs.
• Use refill reminders to maintain steady therapy.
• Discuss generic lamotrigine chewables if appropriate.
• Keep dosing consistent and avoid missed doses to reduce breakthrough symptoms.

Questions to Ask Your Clinician

• Which starting schedule fits my other medications, including valproate or inducers?
• What maintenance dose range should we target for my condition?
• How should we handle missed doses or temporary interruptions?
• What warning signs of rash or hypersensitivity require immediate care?
• Could contraceptives or pregnancy affect lamotrigine dosing?
• When should levels or clinical response be reassessed after titration changes?
• Is a generic lamotrigine chewable appropriate for my prescription?
