Hydroxyzine Syrup Dosing for Pediatric Patients

For pediatric patients, hydroxyzine syrup should be dosed as follows: children under 6 years should receive 50 mg daily in divided doses, while children 6 years and older should receive 50-100 mg daily in divided doses. 1

Age-Based Dosing Guidelines

  • Children under 6 years of age: 50 mg total daily dose, administered in divided doses throughout the day 1
  • Children 6 years and older: 50-100 mg total daily dose, administered in divided doses throughout the day 1
  • For premedication/sedation: 0.6 mg/kg of body weight 1

Indications for Use in Pediatrics

  • Anxiety and tension: Hydroxyzine syrup can be used for symptomatic relief of anxiety in pediatric patients 1
  • Pruritus management: Effective for managing pruritus due to allergic conditions such as chronic urticaria and atopic dermatoses 1
  • Premedication sedation: Can be used as a sedative for premedication before procedures 1
  • Anxiolysis for medical imaging: Hydroxyzine is approved for anxiolytic use in both Europe and the United States for pediatric patients undergoing imaging procedures 2

Administration Considerations

  • Hydroxyzine syrup formulation facilitates administration to children who may have difficulty swallowing tablets 3
  • The medication can be administered orally even after initial treatment is initiated via intramuscular route 1
  • Dosage should be adjusted according to the patient's response to therapy 1

Safety Considerations

  • Hydroxyzine has been shown to be a safe oral sedative when used at proper dosages 4
  • Most common adverse effects are drowsiness and dry mouth 4
  • Respiratory complications may occur due to synergistic reactions when combined with other sedatives 4
  • Monitor for potential sedative effects, especially when combined with other medications 4, 5

Special Populations

  • Renal impairment: Reduce the dose by half in patients with renal impairment 3
  • Severe renal impairment: Avoid use in patients with creatinine clearance <10 mL/min 3
  • Hepatic impairment: Avoid use in patients with severe hepatic impairment due to increased sedating effects 3

Combination Therapy Considerations

  • When combined with other sedatives like midazolam, no significant differences in physiological parameters have been observed compared to other sedative combinations 5, 6
  • Hydroxyzine (1 mg/kg) has been safely used in combination with midazolam for pediatric dental procedures 5

Monitoring Recommendations

  • Although hydroxyzine is generally safe, monitoring of vital signs is recommended when used for sedation purposes 4, 7
  • No significant changes in heart rate, oxygen saturation, or respiratory rate have been observed with standard dosing 5

Remember that hydroxyzine dosing should be carefully calculated based on the child's weight and age, and the syrup formulation provides flexibility for accurate dosing in the pediatric population.
