Notes and Remarks

  • Appropriate dosing and regular monitoring are essential to optimize the therapeutic benefits of hydroxyurea and minimize the risk of adverse events.
  • Health care providers should offer clear, age-appropriate information to caregivers, children and adolescents to support informed decision-making and adherence.
  • Acceptability and uptake of hydroxyurea can be enhanced through effective communication, counselling and advocacy by health care providers.
  • Adolescents receiving hydroxyurea should be counselled on the need for contraception, as hydroxyurea is contraindicated during the first trimester of pregnancy due to potential embryo-fetal toxicity.
