What is Divalproex Tablet?
Divalproex sodium is a prescription medication often sold under the brand name Depakote. It is a stable compound of sodium valproate and valproic acid that converts to valproic acid in the body. This formulation, often with an enteric coating, is frequently chosen over valproic acid alone because it can help reduce stomach upset. Divalproex is an antiepileptic drug (AED) and mood stabilizer that is believed to work by calming overactive nerves in the brain, though its exact mechanism isn't fully clear.
Its main uses are in treating seizure disorders, managing bipolar disorder, and preventing migraines. The appropriate use and dosage are determined by the specific condition being treated, the medication's form (delayed-release or extended-release), and the individual patient.
Divalproex for Epilepsy and Seizure Control
Divalproex is a key treatment for various seizure disorders. It can be used by itself or with other antiepileptic drugs.
Types of seizures treated:
- Complex Partial Seizures: Can be used alone or with other medications in adults and children aged 10 and older.
- Simple and Complex Absence Seizures: Effective for absence seizures.
- Other Seizure Types: Also used with other medications for additional seizure types like tonic-clonic seizures, under medical supervision.
This medication is thought to work by increasing levels of GABA, a brain chemical that helps regulate nerve activity and can help prevent the abnormal nerve firings that cause seizures.
Managing Bipolar Disorder with Divalproex
Divalproex is indicated for the treatment of acute manic or mixed episodes linked to bipolar disorder. It acts as a mood stabilizer to help manage the extreme high moods of mania.
How Divalproex helps bipolar disorder:
- Stabilizes mood: Helps to regulate mood swings.
- Treats acute mania: Particularly effective for the manic phase.
- May reduce impulsivity: Some studies suggest it can help with symptoms like impulsive aggression.
Preventing Migraine Headaches
Divalproex is approved for preventing migraine headaches in adults. It is important to understand that it is used to stop migraines before they start, not to treat a migraine that is already happening.
How Divalproex prevents migraines:
- Reduces frequency: Studies show it can lower the number of migraine attacks in some people.
- Possible mechanisms: While not fully understood, it may affect brain pathways related to pain.
- Effective for many: It can be a well-tolerated option for individuals with regular migraines.
Divalproex vs. Valproic Acid: A Comparison
These are both forms of valproate, but their differences in how they are made can affect how a patient experiences the medication.
| Feature | Divalproex Sodium (e.g., Depakote) | Valproic Acid (e.g., Depakene) |
|---|---|---|
| Formulation | Stable coordination compound | Immediate-release liquid or capsule |
| Release | Delayed-Release (DR) or Extended-Release (ER) | Immediate-release |
| Dosing | Once or twice daily (especially ER) | Typically multiple daily doses |
| GI Tolerability | Better, due to enteric coating | Higher risk of nausea, vomiting, indigestion |
| Cost | Often higher | Lower (available as generic) |
| Bioavailability | Similar after absorption | Similar after absorption |
Potential Side Effects and Important Warnings
Divalproex can have side effects and carries significant warnings. Common side effects may include:
- Stomach upset (nausea, vomiting, pain)
- Hair loss
- Headache
- Dizziness and tiredness
- Tremor
- Weight gain
Significant risks and warnings include:
- Liver Damage: Can cause liver failure, sometimes fatal, particularly in young children and those with certain genetic conditions.
- Pancreas Inflammation: Pancreatitis is a serious, potentially life-threatening risk.
- Pregnancy Risks: Poses significant risks to a developing fetus, including birth defects and lower IQ. It is generally not recommended for pregnant women or those who could become pregnant and are not using effective birth control, especially for migraine prevention.
- Low Platelet Count: Can reduce platelet levels, affecting blood clotting.
- Suicidal Thoughts: Patients should be monitored for changes in mood or suicidal ideation, especially early in treatment.
- Urea Cycle Disorders: Should not be used in individuals with known urea cycle disorders due to the risk of high ammonia levels.
It is crucial to take this medication exactly as directed and never stop taking it suddenly, as this can lead to serious issues, including dangerous seizures. Your doctor will likely require regular monitoring, including blood tests.

Conclusion
Divalproex Tablet is a versatile medication used effectively for epilepsy, the manic phase of bipolar disorder, and preventing migraine headaches. Its formulation often provides better stomach tolerance than immediate-release valproic acid. While beneficial for many, it comes with potential side effects and serious warnings, particularly regarding pregnancy and liver health. Therefore, its use requires careful medical oversight and adherence to directions and warnings. Always consult with a healthcare professional for personalized medical advice.
