Labeled Products with Significant Changes for Dosing or Risk Midazolam (Versed): Sedation/anxiolysis/amnesia- higher risk of serious life-threatening situations in children with congenital heart disease and pulmonary hypertension and identified need to begin therapy at lower end of dosing range in this subpopulation to prevent respiratory compromise Etodolac (Lodine): JRA sign/symptom relief (6yr-16yr) -higher dose (per kg basis) needed in younger children approximately 2 times the lower dose recommended in adults for effective treatment Fluvoxamine (Luvox): Rx of OCD - higher doses in adolescents than previously recommended; girls ages 8-11 years may require lower doses.
Labeled Products with Significant Changes for Dosing or Risk Gabapentin (Neurontin): - adjunctive Rx in partial seizures - higher doses required in children less than 5 years of age in order to control seizures; new adverse events (e.g. hostility and aggression) identified in children less than12 years Propofol (Diprivan): -induction and/or maintenance of anesthesia - increased mortality when used for pediatric ICU sedation over standard sedative agents (9% vs. 4%); serious bradycardia when propofol is concomitantly administered with fentanyl Sevoflurane (Ultane): induction and maintenance of general anesthesia - rare cases of seizures reported in children without a previous seizure history
Labeled Products with Significant Changes for Dosing or Risk Ribavirin/Intron A (Rebetron): increased incidence of suicidal ideation or attempts among pediatric patients as compared with adults (2.4% vs. 1%); decreased rate of linear growth and weight gain during therapy, with general reversal in the post treatment period Pimecrolimus (Elidel) - indicated for short-term and intermittent long-term therapy in mild-moderate atopic dermatitis in non-immunocompromised patients >2years of age; (NOT RECOMMENDED in patients <2 years of age for safety concerns including infections, pyrexia, and diarrhea)
Labeled Products with Significant Changes for Dosing or Risk Betamethasone (Diprolene AF): Corticosteroid responsive dermatoses; NOT RECOMMENDED in pediatric patients <12 years of age; HPA axis suppression; local adverse reactions, including signs of skin atrophy in 10% of patients 3 mo-12 yrs of age Betamethasone (Diprosone Cream, Ointment, Lotion): NOT RECOMMENDED in patients <12 years of age; HPA axis suppression; local adverse reactions included signs of skin atrophy (telangectasia, bruising, shininess) in cream & ointment but not lotion Betamethasone (Lotrisone): NOT RECOMMENDED in patients <17 years of age; HPA axis suppression
Labeled Product with Safety and Effectiveness Issue Buspirone (Buspar) • - Safety and effectiveness were NOT established in patients 6-17 years of age for treatment of • General Anxiety Disorder at doses recommended • for adults; • - AUC and Cmax of buspirone and active metabolite were equal to or higher in children and adolescents as compared with adult PK parameters
