ZENOXA 300MG

# Oxcarbazepine 300 mg ## SHORT DESCRIPTION Oxcarbazepine 300 mg is an **anticonvulsant (antiepileptic) medicine** primarily used to control certain types of seizures, particularly **focal-onset seizures**. It may be prescribed alone or together with other antiseizure medicines. Oxcarbazepine works by helping stabilize abnormal electrical activity in the brain and should be taken regularly as prescribed. ## KEY BENEFITS * Helps control focal-onset seizures * Helps reduce abnormal electrical activity in the brain * May reduce the frequency of seizures when taken regularly * Can be used alone or alongside other anticonvulsant medicines * Helps maintain more stable nerve activity in the brain * Available in different strengths to allow individualized dosing ## USES / INDICATIONS Oxcarbazepine 300 mg is primarily used for: * **Focal-onset seizures** * Focal seizures that may occur with or without progression to bilateral tonic-clonic seizures * Epilepsy requiring maintenance anticonvulsant treatment The exact use and age range depend on the specific formulation and local approval. > **Important:** Oxcarbazepine is not generally intended to provide immediate relief during an ongoing seizure. Follow your doctor's seizure emergency plan when applicable. ## HOW IT WORKS Oxcarbazepine and its active metabolite affect **voltage-sensitive sodium channels** in nerve cells. By helping stabilize these channels, the medicine reduces repetitive abnormal electrical firing in neurons. This helps prevent the spread of abnormal electrical activity responsible for seizures. ## DOSAGE & ADMINISTRATION * Take Oxcarbazepine 300 mg exactly as prescribed. * It may be taken with or without food. * Take doses at evenly spaced times when prescribed more than once daily. * Swallow tablets with water unless your specific formulation has different instructions. * Do not change the dose without consulting your doctor. * **Do not stop oxcarbazepine suddenly**, as this may worsen seizures or increase seizure frequency. * Your doctor may gradually adjust the dose according to seizure control and tolerability. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. Do not take two doses together to compensate. ## SIDE EFFECTS ### Common Side Effects * Dizziness * Drowsiness * Headache * Tiredness * Nausea * Vomiting * Double vision * Blurred vision * Difficulty with coordination * Tremor * Abdominal discomfort These effects may be more noticeable when treatment is first started or when the dose is increased. ### Serious Side Effects Seek immediate medical attention for: * Severe skin rash * Blistering or peeling skin * Swelling of the face, lips, tongue, or throat * Difficulty breathing * Severe confusion * Fainting * Significant weakness * Severe headache accompanied by nausea or confusion * Worsening seizures * Signs of low sodium, such as severe nausea, confusion, drowsiness, or seizures Rare but serious skin reactions such as **Stevens-Johnson syndrome and toxic epidermal necrolysis** can occur. ## PRECAUTIONS & WARNINGS Tell your doctor before taking oxcarbazepine if you have: * Kidney disease * Liver disease * Low blood sodium * A history of allergic reactions to anticonvulsants * A history of severe skin reactions * Heart rhythm problems * Any other neurological or psychiatric condition ### Low Sodium Oxcarbazepine can cause **hyponatremia (low sodium levels)**, which may occasionally be severe. Contact your doctor if you experience: * Nausea * Headache * Unusual tiredness * Confusion * Drowsiness * Muscle weakness * Seizures Your doctor may recommend blood tests to monitor sodium, particularly if you are at increased risk. ### Serious Skin Reactions Stop and seek urgent medical evaluation if you develop a widespread rash, blistering, peeling skin, sores in the mouth, or swelling. People with certain genetic backgrounds, particularly some individuals of **Asian ancestry**, may have an increased risk of serious skin reactions associated with HLA-B*1502. Genetic testing may be considered before treatment in appropriate patients. ### Dizziness and Drowsiness Oxcarbazepine can impair coordination, concentration, and alertness. Avoid driving or operating machinery until you know how it affects you. ### Suicidal Thoughts Antiepileptic medicines may be associated with mood changes or suicidal thoughts in some patients. Report significant changes in mood, behavior, or thoughts of self-harm promptly. ### Pregnancy Do not stop oxcarbazepine suddenly during pregnancy without medical advice. Discuss pregnancy planning with your doctor because uncontrolled seizures can also pose serious risks. ## DRUG INTERACTIONS Oxcarbazepine can interact with several medicines, including: * **Hormonal contraceptives** — oxcarbazepine can reduce their effectiveness. * Other anticonvulsants such as phenytoin, carbamazepine, phenobarbital, and lamotrigine. * **Valproic acid** and other antiseizure medicines. * Certain medicines affected by liver enzyme induction. * Medicines that can lower sodium levels, increasing the risk of hyponatremia. * Alcohol and other medicines that cause drowsiness. ### Hormonal Birth Control Oxcarbazepine may make hormonal contraceptives less effective. Discuss alternative or additional contraception with your healthcare professional. Always tell your doctor or pharmacist about all prescription medicines, over-the-counter medicines, vitamins, and herbal supplements you take. ## STORAGE INFORMATION * Store Oxcarbazepine 300 mg according to the manufacturer's instructions. * Keep the tablets in the original packaging. * Store at room temperature unless otherwise specified. * Protect from excessive heat, moisture, and direct sunlight. * Keep out of the sight and reach of children. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged. ## PRESCRIPTION STATUS **Prescription Medicine** Oxcarbazepine 300 mg should be used under the supervision of a qualified healthcare professional, particularly because dose adjustments and monitoring may be necessary. ## GENUINE MEDICINE ASSURANCE When purchasing Oxcarbazepine 300 mg: * Purchase from a licensed and reputable pharmacy. * Check that the packaging is sealed and intact. * Verify the medicine name and strength. * Check the batch number and expiry date. * Ensure the product has been stored appropriately. * Avoid products with damaged, altered, or suspicious packaging. * Purchase from authorized pharmaceutical suppliers. * Consult a pharmacist if you have concerns about authenticity. ## FAQ — FREQUENTLY ASKED QUESTIONS ### What is Oxcarbazepine 300 mg used for?
