DIVAA 500MG

# Valproic Acid 500 mg ## SHORT DESCRIPTION Valproic Acid 500 mg is a **prescription medicine** used primarily to control certain types of seizures and, depending on the formulation and local approval, to help manage **bipolar disorder** and prevent **migraine headaches**. Valproic acid is an anticonvulsant that helps stabilize abnormal electrical activity in the brain. It may be used alone or together with other medicines, depending on the patient's condition. > **Important:** Valproic acid can cause serious liver injury, pancreatitis, blood-related problems, and major fetal harm during pregnancy. It should be used under close medical supervision. ## KEY BENEFITS * Helps control certain types of seizures * Helps reduce abnormal electrical activity in the brain * May be used in the management of bipolar disorder when prescribed * May help prevent migraine attacks in appropriate patients * Can be used alone or with other anticonvulsant medicines when medically appropriate * Helps maintain more stable neuronal activity ## USES / INDICATIONS Valproic Acid 500 mg may be prescribed for: * **Epilepsy and seizure disorders** * Generalized seizures * Absence seizures * Myoclonic seizures * Certain focal seizures * **Bipolar disorder**, depending on the formulation and local approval * **Prevention of migraine attacks** in selected patients Valproic acid is **not generally used to immediately stop an ongoing seizure** unless a specific injectable formulation and emergency treatment protocol is being used. ## HOW IT WORKS Valproic acid has several effects on the nervous system. One important action is increasing the availability of **gamma-aminobutyric acid (GABA)**, an inhibitory neurotransmitter in the brain. By enhancing inhibitory activity and affecting ion channels involved in neuronal signaling, valproic acid helps reduce excessive or abnormal electrical activity in the brain. This stabilizing effect contributes to its anticonvulsant and mood-stabilizing properties. ## DOSAGE & ADMINISTRATION * Take Valproic Acid 500 mg exactly as prescribed by your doctor. * The dose is individualized according to the condition being treated, age, body weight, response, formulation, and blood levels when monitoring is required. * Take it at approximately the same time each day. * Swallow the medicine with water unless your specific formulation has different instructions. * Take with food if it causes stomach discomfort. * **Do not stop valproic acid suddenly**, particularly if it is being used for epilepsy, because this can increase the risk of seizures. * Your doctor may periodically monitor blood tests and valproate concentrations. ### Missed Dose Take the missed dose when remembered unless it is almost time for your next dose. Do not take two doses together to compensate. ## SIDE EFFECTS ### Common Side Effects * Nausea * Vomiting * Abdominal discomfort * Diarrhea * Dizziness * Drowsiness * Tremor * Headache * Increased appetite * Weight gain * Hair thinning or hair loss ### Serious Side Effects Seek immediate medical attention for: * Severe or persistent abdominal pain * Repeated vomiting * Yellowing of the skin or eyes * Dark urine * Severe weakness or unusual tiredness * Easy bruising or unusual bleeding * Severe confusion or excessive drowsiness * Loss of coordination * Facial swelling or difficulty breathing * Severe skin rash * Symptoms suggesting pancreatitis or liver injury Rare but serious complications include **liver toxicity, pancreatitis, thrombocytopenia, hyperammonemia, and severe skin reactions**. ## PRECAUTIONS & WARNINGS Tell your doctor before taking Valproic Acid if you have: * Liver disease * A history of liver problems related to medicines * Pancreatic disease or previous pancreatitis * A bleeding or clotting disorder * A metabolic disorder such as urea-cycle disorder * Mitochondrial disease, particularly POLG-related disorders * Kidney disease * A history of significant depression or suicidal thoughts * Any other neurological condition ### Liver Toxicity Valproic acid can cause **serious and potentially life-threatening liver injury**, particularly during the first months of treatment and in certain high-risk patients. Your doctor may order liver function tests before and during treatment. Seek medical attention for: * Persistent vomiting * Loss of appetite * Severe weakness * Abdominal pain * Yellowing of the skin or eyes * Dark urine ### Pancreatitis Valproic acid can rarely cause **acute pancreatitis**, which can be life-threatening. Seek urgent medical care for persistent severe abdominal pain, particularly when accompanied by nausea or vomiting. ### Pregnancy Warning **Valproic acid carries a major risk of serious birth defects and neurodevelopmental problems when used during pregnancy.** Women and girls who can become pregnant should discuss effective pregnancy prevention and treatment alternatives with their healthcare professional. Do not stop valproic acid suddenly without medical advice, particularly if it is being used to control seizures. ### Suicidal Thoughts Antiepileptic medicines may be associated with changes in mood or suicidal thoughts in some patients. Report new or worsening depression, unusual behavior changes, or thoughts of self-harm promptly to a healthcare professional. ### Drowsiness and Dizziness Valproic acid may cause drowsiness or dizziness. Avoid driving or operating machinery until you know how the medicine affects you. ## DRUG INTERACTIONS Valproic acid can interact with many medicines, including: * **Lamotrigine** — valproic acid can significantly increase lamotrigine levels and the risk of serious skin reactions. * **Carbapenem antibiotics** such as meropenem — can markedly reduce valproate concentrations and may lead to loss of seizure control. * **Aspirin and salicylates** — may increase free valproate levels and toxicity risk. * **Warfarin and other anticoagulants** — may increase bleeding risk or affect coagulation. * Other anticonvulsants, including phenytoin, phenobarbital, and carbamazepine. * Alcohol and other medicines that cause sedation. * Certain medicines that affect liver metabolism. * **Topiramate** — combined use may increase the risk of hyperammonemia and encephalopathy. Always tell your doctor or pharmacist about every prescription medicine, over-the-counter medicine, vitamin, and herbal supplement you take. ## STORAGE INFORMATION * Store Valproic Acid 500 mg according to the manufacturer's instructions. * Keep the medicine in its original packaging. * Store at room temperature unless otherwise specified. * Protect from excessive heat, moisture, and direct sunlight. * Keep the medicine out of the sight and reach of children. * Do not use after the expiry date. * Do not use tablets or capsules if the packaging is damaged. ## PRESCRIPTION STATUS **Prescription Medicine** Valproic Acid 500 mg should be taken only under the supervision of a qualified healthcare professional.
