Therapeutic drug monitoring (TDM) advice

You can obtain advice on Therapeutic Drug Monitoring (TDM) from your ward pharmacist (via pager) or by contacting the Queensland Children’s Hospital (QCH) Pharmacy Department.

Paediatric TDM differs from that relating to adults, so please don’t hesitate to contact your Clinical pharmacist for advice regarding starting doses, or advice on interpreting blood levels and advice regarding appropriate dose adjustments.
