Divalproex: Uses, Dosage, Side Effects and More

Introduction: What is Divalproex?

Divalproex, commonly known as Divalproex Sodium, is a medication primarily used to treat various neurological and psychiatric conditions. It is a derivative of valproic acid and is classified as an anticonvulsant and mood-stabilizing agent. Divalproex is effective in managing epilepsy, bipolar disorder, and preventing migraine headaches. Its ability to stabilize mood and control seizures makes it a vital option in the treatment of these conditions.

Uses of Divalproex

Divalproex is approved for several medical uses, including:

1. Epilepsy: It is used to control various types of seizures, including generalized tonic-clonic seizures, absence seizures, and partial seizures.
2. Bipolar Disorder: Divalproex is effective in treating manic episodes associated with bipolar disorder, helping to stabilize mood swings.
3. Migraine Prevention: It is prescribed to reduce the frequency of migraine attacks in individuals who suffer from chronic migraines.

How It Works

Divalproex works by increasing the levels of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is an inhibitory neurotransmitter, meaning it helps calm the brain's activity. By enhancing GABA's effects, Divalproex helps to reduce excessive electrical activity in the brain that can lead to seizures and mood disturbances. In simpler terms, it helps to "calm down" the brain, making it less likely to experience seizures or mood swings.

Dosage and Administration

The dosage of Divalproex varies based on the condition being treated, the patient's age, and their response to the medication.

• Adults: The typical starting dose for epilepsy is 10-15 mg/kg/day, which may be increased gradually. For bipolar disorder, the initial dose is usually around 750 mg/day, adjusted as needed.
• Pediatrics: For children, the starting dose is generally 10-15 mg/kg/day, with adjustments made based on the child's response and tolerance.

Divalproex is available in various forms, including:

• Tablets: Extended-release and delayed-release formulations.
• Sprinkle Capsules: Can be opened and sprinkled on food for easier administration.
• Injection: For patients who cannot take oral medications.

Drug Interactions

Divalproex can interact with several medications and substances, which may affect its efficacy or increase the risk of side effects. Major interactions include:

• Other Anticonvulsants: Such as phenytoin and carbamazepine, which can alter Divalproex levels.
• Aspirin and Other NSAIDs: These can increase the risk of bleeding.
