Introduction
Paediatric pharmacy services play an important role in ensuring the safe, effective, and appropriate use of medicines in infants, children, and adolescents. Children have age-dependent differences in drug absorption, distribution, metabolism, and elimination, which can influence treatment response and the risk of adverse drug reactions. These differences make medication management in paediatric patients distinct from adult care.
Paediatric pharmacists work alongside physicians, nurses, and other healthcare professionals to optimise medication therapy, prevent medication errors, and support better clinical outcomes.
Key Components of Paediatric Pharmacy Services
1. Accurate dosing and medication verification
Many medicines used in children require weight-based or body-surface-area-based dosing. Paediatric pharmacists help verify the prescribed dose, dosing frequency, route, and maximum recommended dose, where applicable. Calculations should use a current, documented weight and be checked against reliable, age-appropriate references and relevant treatment protocols.
2. Medication safety and error prevention
Medication errors can occur during prescribing, preparation, dispensing, or administration. Paediatric pharmacy services help identify inappropriate doses, duplicate therapy, allergies, contraindications, and clinically significant drug interactions. Standardised concentrations, appropriate measuring devices, clear labelling, and independent checks for selected high-risk medicines can further strengthen medication safety.
3. Formulation and preparation of medicines
Children may be unable to swallow conventional tablets or capsules, and suitable commercial formulations may not always be available. Pharmacists help select appropriate dosage forms and, when necessary, support the safe preparation of suitable formulations. Compatibility, stability, concentration, storage conditions, and accurate measurement are important considerations.
4. Monitoring treatment effectiveness and adverse effects
Pharmacists review clinical response, laboratory findings, relevant drug concentrations, and potential adverse effects. Therapeutic drug monitoring may be required for selected medicines with a narrow therapeutic index or significant toxicity risks. Monitoring should be tailored to the medicine, the child's age and clinical condition, and the applicable treatment protocol.
5. Counselling parents and caregivers
Parents and caregivers need clear instructions on medicine administration, dosing schedules, storage, adherence, and potential warning signs. For liquid medicines, oral syringes or other appropriate measuring devices should be used rather than household teaspoons. Counselling should also address missed doses, accidental ingestion prevention, and when to seek medical advice.
The Role of Multidisciplinary Collaboration
Effective paediatric pharmacy services depend on collaboration among pharmacists, paediatricians, nurses, and other members of the healthcare team. Pharmacists contribute to medication reconciliation, clinical rounds, formulary decisions, protocol development, discharge planning, and staff education. Their involvement is particularly valuable in high-risk settings, including neonatal and paediatric intensive care, emergency departments, and paediatric oncology.
Conclusion
Paediatric pharmacy services are essential to safe and effective medication use in children. Through accurate dosing, medication review, monitoring, formulation support, and caregiver education, paediatric pharmacists help reduce preventable medication-related harm and promote individualised treatment.
