Conversion: 1.5 g Levetiracetam = 1500 mg

1.5 grams (g) of Levetiracetam (Levipil) equals 1500 milligrams (mg).

Basic Conversion

• 1 gram = 1000 milligrams
• Therefore: 1.5 g × 1000 = 1500 mg

Clinical Context for Levetiracetam 1500 mg Dosing

This is a commonly used dose in clinical practice:

Standard Maintenance Dosing

• For chronic epilepsy management: Levetiracetam 1500 mg per day (750 mg twice daily) falls within the typical maintenance range of 1000-3000 mg/day in divided doses 1, 2
• For adjunctive therapy in refractory focal seizures: The 1500 mg/day dose represents a mid-range therapeutic dose, with studies showing efficacy at 1000-3000 mg/day 2, 3

Acute/Loading Dose Context

• For status epilepticus: A single 1500 mg dose would be considered a maintenance dose rather than a loading dose, as loading doses typically range from 2000-2500 mg IV (or 40 mg/kg, maximum 2500 mg) 1, 4
• For critically ill patients with augmented renal clearance: 1500 mg twice daily (3000 mg/day total) is recommended as a starting dose to achieve therapeutic levels 5

Administration Considerations

• Levetiracetam can be administered orally or intravenously at equivalent doses 6
• The extended-release formulation allows once-daily dosing of 1500 mg, which may improve compliance 6
• Renal dose adjustment is necessary in patients with renal impairment, though not required in healthy individuals 7, 5
