Epival Tablet Uses, Dosage, Benifits, Side Effects & Price

Epival is a prescription anti-epileptic medicine whose main salt is sodium valproate or valproic acid. It’s manufactured primarily by Sun Pharma Laboratories Ltd and comes as tablets, CR/ER prolonged-release tablets, and oral syrup/solution.

What Is Epival Used For?

Primary indications

Epilepsy / Seizure disorders: Used alone or with other anti-epileptics to treat various forms of epilepsy characterized by abnormal brain activity, uncontrolled jerking, fits, and loss of consciousness.
Manic episodes in bipolar disorder: Helps prevent extreme mood swings by stabilizing abnormal brain signals.
Migraine prophylaxis: Off-label/secondary use to prevent migraine headaches with severe headache, eye pain, nausea, and vomiting.

How it works

Epival belongs to the anti-epileptic class. It increases GABA levels in the brain and blocks voltage-gated sodium channels, which calms overactive nerve signals that trigger seizures and mood swings.

Dosage Guidelines

Always follow your doctor’s prescription. Dosing is individualized by age, weight, condition, and response.

For Epilepsy – Adults

Starting dose: Usually 15 mg/kg/day, taken after meals.
Maintenance: Gradually increased by 5–10 mg/kg per week if needed. Typical range 1000–2000 mg/day, but doses >45 mg/kg/day need careful monitoring.
CR tablets: Can be given once or twice daily. Initial dose for mania is 750 mg/day, or 20 mg/kg body weight.

For Bipolar Mania – Adults

Initial: 750 mg/day or 20 mg/kg/day.
Usual maintenance: 1000–2000 mg/day, titrated to lowest effective dose.

Children & Adolescents

Epival CR is not recommended for treating mania in patients <18 years. For epilepsy, pediatric dosing is weight-based and must be decided by a pediatric neurologist.

Elderly

Same initial dose: 15 mg/kg/day, with slower titration due to increased sensitivity.

Administration tips

Take with or after food if stomach upset occurs.
CR tablets must be swallowed whole with fluid; may be halved but not chewed/crushed.
Do not stop suddenly – can worsen seizures. Taper under medical supervision.

Missed dose: Take as soon as you remember, but skip if it’s almost time for the next dose. Never double up.
Overdose: Symptoms include nausea, vomiting, dizziness, CNS/respiratory depression. Seek emergency care immediately.
