Dosage & Administration

Standard regimens per Canadian guidelines

Understanding how to properly use Valproic Acid is crucial for effective treatment. For adults, the typical starter doses vary depending on the condition being treated:

• Epilepsy: Initial dose typically begins at 600 mg daily, which can be divided into 2-3 doses. Maintenance typically ranges from 1,000-2,000 mg daily.
• Bipolar Disorder: Initial dosing generally starts at 750 mg-1,000 mg daily.
• Migraine Prophylaxis: Usual dosing falls between 500 mg-1,000 mg daily.

For children, dosing is weight-based, often around 20-30 mg/kg/day split into two or three doses. Adjustments are made gradually, increasing by 5-10 mg/kg/week as needed.

Adjustments by patient type (with Canadian clinical notes)

Special considerations are necessary for certain populations:

The elderly usually require a lower effective dose. Careful titration is essential to minimize side effects.

For patients with liver impairment, extreme caution is advised. In cases of active or advanced liver disease, using Valproic Acid is contraindicated. Regular monitoring is essential to ensure safety.

Pediatric patients often need tailored dose adjustments, emphasizing close monitoring, especially during initial treatment phases.
