LAMEZ 25MG

# LAMOTRIGINE 25 MG ## SHORT DESCRIPTION **Lamotrigine 25 mg** is an anticonvulsant medicine used to help control certain types of **seizures (epilepsy)**. It is also used as a **mood stabilizer for maintenance treatment of bipolar disorder** in appropriate patients. Lamotrigine works by reducing excessive electrical activity in the brain. The **25 mg strength is commonly used as a low starting dose during gradual dose escalation**, which is particularly important because increasing lamotrigine too quickly can increase the risk of serious skin reactions. ## KEY BENEFITS * Helps control certain types of **epileptic seizures**. * May be used alone or alongside other anticonvulsant medicines for selected seizure disorders. * Used for **maintenance treatment of bipolar disorder** in appropriate adults. * Helps stabilize abnormal electrical activity in the brain. * The 25 mg strength is useful for **gradual dose titration**. * Can be taken orally and is available in several dosage strengths. ## USES / INDICATIONS Lamotrigine may be prescribed for: * **Epilepsy** and certain seizure disorders. * Focal (partial-onset) seizures. * Generalized tonic-clonic seizures. * Certain seizures associated with **Lennox-Gastaut syndrome**. * Maintenance treatment of **bipolar I disorder** to help reduce recurrence of mood episodes in appropriate patients. The exact approved indications can vary depending on the country, formulation, age group, and product labeling. > **Important:** Lamotrigine is generally **not used to treat an acute manic or mixed episode** of bipolar disorder. Its principal role in bipolar disorder is maintenance treatment. ## HOW IT WORKS Lamotrigine primarily works by blocking **voltage-sensitive sodium channels** in nerve cells. This reduces the release of excitatory neurotransmitters, particularly **glutamate and aspartate**, helping to stabilize excessive electrical activity in the brain. ### Overall Action **Lamotrigine → blocks voltage-sensitive sodium channels → reduces excessive neuronal activity → helps prevent seizures and stabilizes mood.** ## DOSAGE & ADMINISTRATION Lamotrigine dosing must be **individualized and increased gradually**. The appropriate dose depends on: * The condition being treated. * Age. * Other anticonvulsant medicines being taken. * Whether **valproate/valproic acid** is being used. * Kidney and liver function. * Response to treatment. * Tolerability. ### Lamotrigine 25 mg **25 mg is commonly used as a starting or titration strength**, rather than being the usual long-term maintenance dose for many patients. A healthcare professional may start with a low dose and gradually increase it over several weeks. ### General Administration * Take exactly as prescribed. * Take it at the same time each day. * It can generally be taken **with or without food**. * Swallow tablets with water unless your specific formulation has different instructions. * Do not increase the dose faster than instructed. * Do not stop treatment abruptly without medical advice. ### Missed Dose If you miss a dose, take it when remembered unless it is nearly time for your next dose. **Do not take two doses together.** If lamotrigine has been stopped for **several days**, contact your healthcare professional before restarting it. Depending on the duration of interruption, it may be necessary to restart using the initial titration schedule. ## SIDE EFFECTS Common or possible side effects include: * Headache. * Dizziness. * Sleepiness or drowsiness. * Nausea. * Vomiting. * Blurred or double vision. * Tremor. * Lack of coordination. * Fatigue. * Insomnia. * Dry mouth. ### Serious Skin Reactions Lamotrigine can rarely cause serious and potentially life-threatening skin reactions, including: * **Stevens-Johnson syndrome (SJS)**. * Toxic epidermal necrolysis (TEN). * Drug reaction with eosinophilia and systemic symptoms (**DRESS**). Seek **immediate medical attention** if you develop: * A new rash. * Blistering or peeling skin. * Sores in the mouth or eyes. * Fever with a rash. * Facial swelling. * Swollen lymph nodes. * Difficulty breathing. * Unusual weakness or severe illness following the appearance of a rash. **Do not ignore a new rash while taking lamotrigine.** ## PRECAUTIONS & WARNINGS ### Serious Skin Rash — IMPORTANT The risk of serious rash is increased when: * Lamotrigine is started at too high a dose. * The dose is increased too rapidly. * Lamotrigine is taken with **valproate or valproic acid**. Any new unexplained rash should be evaluated promptly by a healthcare professional. ### Do Not Stop Abruptly Stopping lamotrigine suddenly can increase seizure frequency and may cause serious complications in people with epilepsy. Dose reduction should generally be performed under medical supervision. ### Bipolar Disorder Lamotrigine is primarily used for **maintenance treatment** of bipolar disorder. It is not generally relied upon for rapid treatment of acute mania. Patients should be monitored for changes in mood, worsening depression, or suicidal thoughts. ### Suicidal Thoughts Antiepileptic medicines, including lamotrigine, may be associated with an increased risk of suicidal thoughts or behavior in some patients. Seek immediate professional help if significant mood changes or suicidal thoughts occur. ### Liver or Kidney Problems Patients with significant liver or kidney impairment may require dose adjustments. ### Hypersensitivity Rarely, lamotrigine can cause a serious systemic hypersensitivity reaction involving multiple organs. Symptoms such as fever, rash, facial swelling, swollen lymph nodes, or organ-related symptoms require urgent medical evaluation. ### Pregnancy If you are pregnant or planning pregnancy, consult your healthcare professional before changing lamotrigine treatment. Abruptly stopping an anticonvulsant can itself be harmful, so treatment decisions during pregnancy should be medically supervised. ### Driving and Operating Machinery Lamotrigine can cause dizziness, blurred or double vision, or drowsiness. Avoid driving or operating machinery until you know how the medicine affects you. ## DRUG INTERACTIONS ### Valproate / Valproic Acid **Valproate significantly increases lamotrigine levels and prolongs its half-life**, increasing the risk of serious skin reactions. When used together, lamotrigine generally requires a **much slower and lower-dose titration schedule**. ### Carbamazepine Carbamazepine can increase the metabolism of lamotrigine and lower lamotrigine concentrations. It may also increase certain neurological adverse effects in some patients. ### Phenytoin Phenytoin can increase lamotrigine metabolism and reduce its blood concentration. ### Phenobarbital and Primidone These medicines may increase lamotrigine metabolism and reduce its effectiveness. ### Rifampicin Rifampicin can increase lamotrigine clearance and reduce its concentration. ### Hormonal Contraceptives Estrogen-containing hormonal contraceptives can increase lamotrigine clearance and may significantly reduce lamotrigine concentrations. Changes in hormonal contraception can therefore require clinical reassessment of lamotrigine dosing. ### Other Medicines Other anticonvulsants and medicines may affect lamotrigine levels or increase adverse effects. Always tell your doctor or pharmacist about **all prescription medicines, OTC medicines, vitamins, supplements, and herbal products** you use. ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep at room temperature unless otherwise specified. * Protect from excessive heat and moisture. * Keep away from direct sunlight. * Keep tablets in their original packaging. * Keep out of reach of children. * Do not use after the expiry date. * Do not use tablets from damaged or tampered packaging. ## PRESCRIPTION STATUS **Lamotrigine 25 mg is generally a prescription medicine.** Because lamotrigine requires careful dose titration and can rarely cause serious skin reactions, it should be started and adjusted under the supervision of a qualified healthcare professional.
