TORVATE 500MG

# SODIUM VALPROATE 500 MG ## SHORT DESCRIPTION **Sodium Valproate 500 mg** is a prescription medicine belonging to the **anticonvulsant (antiepileptic)** class. It is primarily used to control certain types of seizures and may also be used for **bipolar disorder** and prevention of **migraine attacks**, depending on local approvals and clinical guidance. Sodium valproate works by increasing inhibitory activity in the brain and reducing excessive electrical activity. The appropriate dose varies according to the condition, age, body weight, response, and other medicines being used. > **Important:** Sodium valproate can cause serious birth defects and developmental problems when used during pregnancy. It should generally be avoided during pregnancy for epilepsy or bipolar disorder unless no suitable alternative exists and specialist advice determines that it is necessary. --- ## KEY BENEFITS * Helps control and prevent certain types of **epileptic seizures**. * May be used for several seizure types, including generalized and focal seizures. * May help stabilize mood in people with **bipolar disorder** when appropriately prescribed. * Can be used as part of long-term seizure-management therapy. * Available in a convenient **500 mg tablet strength** for individualized dosing. * May be used alone or alongside other anticonvulsant medicines depending on the patient's condition. --- ## USES / INDICATIONS ### 1. Epilepsy and Seizure Disorders Sodium valproate may be prescribed for the management of several types of seizures, including: * Generalized tonic-clonic seizures * Absence seizures * Myoclonic seizures * Atonic seizures * Certain focal seizures * Mixed seizure disorders The exact use depends on the patient's diagnosis and clinical circumstances. ### 2. Bipolar Disorder Valproate may be prescribed as a **mood stabilizer** for certain episodes of bipolar disorder, particularly manic or mixed episodes, depending on local treatment guidelines. ### 3. Migraine Prevention Valproate preparations may be used in some countries for **prevention of migraine attacks**. > Sodium valproate is **not a painkiller and does not treat an acute migraine attack**. --- ## HOW IT WORKS Sodium valproate has several effects on brain signaling. It increases the availability and activity of **gamma-aminobutyric acid (GABA)**, an inhibitory neurotransmitter that helps calm excessive electrical activity in the brain. It also affects voltage-gated ion channels involved in neuronal electrical activity. ### Simple Explanation **Sodium valproate → reduces excessive electrical activity in the brain → helps prevent seizures and stabilizes abnormal neuronal activity.** Its effects on neurotransmitter systems also contribute to its mood-stabilizing properties. --- ## DOSAGE & ADMINISTRATION ### Adults The dose depends on the condition being treated, body weight, response, and other medicines. For epilepsy, treatment is generally started at a lower dose and gradually adjusted. A commonly used maintenance range is approximately **1,000–2,000 mg per day**, although some patients may require lower or higher doses under specialist supervision. **Do not use the 500 mg tablet as a standard dose without individualized medical advice.** ### Children Pediatric dosing is generally based on **body weight** and the type of seizure disorder. Children should receive sodium valproate only under appropriate medical supervision. ### How to Take * Take exactly as prescribed. * Take doses at the same time each day. * Swallow tablets with water. * Do not crush or chew **modified-release/enteric-coated formulations** unless the product instructions specifically allow it. * Take with food if it causes stomach upset. * Do not stop treatment suddenly. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. **Do not take two doses together** to make up for a missed dose. ### Important Stopping sodium valproate abruptly can cause seizures to return or become more frequent and, in some patients, may trigger a potentially life-threatening seizure emergency. --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Nausea * Vomiting * Abdominal discomfort * Diarrhea * Drowsiness * Tremor * Dizziness * Headache * Increased appetite * Weight gain * Temporary hair thinning or hair changes Gastrointestinal effects may be reduced by taking the medicine with food. ### Serious Side Effects Seek urgent medical attention for symptoms such as: * Severe or persistent abdominal pain * Repeated vomiting * Yellowing of the skin or eyes * Dark urine * Unusual bleeding or bruising * Severe weakness * Confusion or extreme drowsiness * Loss of coordination * Severe skin rash * Difficulty breathing or facial swelling These may indicate serious complications such as **liver injury, pancreatitis, blood disorders, or a severe allergic reaction**. --- ## PRECAUTIONS & WARNINGS ### Pregnancy – VERY IMPORTANT Sodium valproate is associated with a **high risk of major congenital malformations and neurodevelopmental problems** when used during pregnancy. For epilepsy or bipolar disorder, it should generally **not be used during pregnancy unless specialist medical advice determines that no suitable alternative is available**.
