What is Epival CR Tablets 500mg?
Epival CR 500mg is a controlled-release tablet containing Divalproex Sodium — equivalent to 500mg valproic acid. The CR (controlled-release) formula releases the medicine slowly and steadily into the body — maintaining stable blood levels throughout the day and reducing the risk of side effects compared to immediate-release valproate. It is used to control seizures, stabilise mood in bipolar disorder, and prevent migraines. This is a prescription-only medicine — always take it as directed by your doctor.
What is Epival CR 500mg Used For?
- Epilepsy / Seizures (مرگی) — treats partial and generalised seizures in adults and children — can be used alone or with other anti-epileptic medicines
- Bipolar Disorder — Mania — manages manic episodes marked by extreme excitement, elevated mood, hyperactivity, and impulsive behaviour (جوش، بے قراری، اور انتہائی سرگرمی)
- Migraine Prevention — reduces the frequency and severity of recurring migraine headaches
How Does It Work?
Divalproex sodium breaks down into valproate in the digestive tract and increases GABA levels in the brain — a natural chemical that calms overactive nerve signals. The controlled-release design ensures a smooth, consistent effect throughout the day with fewer peaks and dips in medication levels.
Dosage and How to Take
Epival CR tablets are usually taken once or twice daily with food. Swallow the tablet whole — do not crush, break, or chew it as this will destroy the controlled-release mechanism. Your doctor will set the correct dose based on your condition, weight, and blood valproate levels. Never change the dose or stop taking it without medical advice.
Important Warnings
- Not safe during pregnancy — can cause serious birth defects and developmental problems in the baby
- Regular liver function tests and blood counts are required during treatment
- Never stop suddenly — abrupt discontinuation can cause seizures to return
- Avoid alcohol during treatment
- May cause drowsiness — avoid driving until you know how it affects you
Common Side Effects
Nausea, stomach upset, dizziness, drowsiness, hair thinning, weight gain, and mild hand tremors. The controlled-release formula generally causes fewer and milder side effects than standard valproate tablets. Tell your doctor if any side effect is persistent or severe.
