Comments
Evidence of benefit in acute pain management in children is limited.
Used to treat restless legs syndrome in adults and occasionally in children/adolescents.
Gradual dose increase helps to minimize sedation.
May need to adjust dose in renal impairment.
Space doses at least 2 hours from antacids (decreases absorption of gabapentin).
Adverse effects: somnolence, ataxia, fatigue, and depression.
Not effective as a mood stabilizer in bipolar disorder and should not be used as monotherapy.
