Safe and Precise Medication: Calculating Ceftazidime Dosage for Pediatric Patients

In the realm of pediatric healthcare, ensuring precise medication administration is paramount to provide young patients with the best possible care. This article addresses the process of accurately calculating and administering the correct dosage of Ceftazidime, also known as Fortaz, for a child based on a healthcare provider’s prescription. In this scenario, the healthcare provider has prescribed Ceftazidime at a dosage of 50 mg per kilogram (kg) per day, to be taken orally three times a day (t.i.d.). The child’s weight is 25.5 kg, and the available Fortaz is in an oral suspension labeled at 100 mg per milliliter (ml). Understanding the prescription and the medication’s concentration is essential to ensure that pediatric patients receive the appropriate amount of Ceftazidime for effective treatment.

Understanding Ceftazidime (Fortaz) for Pediatric Patients

Ceftazidime, commercially known as Fortaz, is a cephalosporin antibiotic used to treat a wide range of bacterial infections. It is an important tool in the pediatric healthcare arsenal, providing an effective solution to combat various bacterial illnesses.

Interpreting Healthcare Provider Orders

Healthcare providers are instrumental in prescribing medications, determining the required dosage, and providing administration instructions. In this scenario, the healthcare provider has issued the following order:

  • Medication: Ceftazidime (Fortaz)
  • Dosage: 50 mg per kg per day
  • Frequency: Three times a day (t.i.d.)
  • Route: Per os (PO, which means orally)

The healthcare provider has also provided information about the available Ceftazidime (Fortaz) oral suspension concentration, which is 100 mg per ml.

Determining the Ceftazidime Dosage

To prepare the accurate dose of Ceftazidime, healthcare professionals must consider the prescribed dosage and the available concentration. In this scenario, the provided concentration is 100 mg per ml.

  1. Calculate the total daily dosage required for the child based on the prescribed dose (50 mg per kg per day) and the child’s weight (25.5 kg).
  2. Determine the volume of Ceftazidime oral suspension needed for each dose. To do this, healthcare professionals should divide the total daily dose by the number of daily administrations (three times a day) and then divide it by the concentration of Ceftazidime (Fortaz) oral suspension (100 mg per ml).

    Volume per Dose (ml) = Total Daily Dose (mg) / Concentration (mg per ml) x Number of Doses per Day

Administering Ceftazidime (Fortaz) for Pediatric Patients

When instructing the caregiver or child on administering Ceftazidime (Fortaz) as part of their treatment, healthcare professionals should ensure adherence to the following steps:

  1. Ensure the caregiver or child has the prescribed Ceftazidime (Fortaz) oral suspension, a clean medicine dropper or dosing cup, and access to a timer or clock for accurate timing.
  2. Instruct the caregiver or child to gently shake the Ceftazidime (Fortaz) oral suspension bottle to ensure uniform distribution of the medication.
  3. Provide guidance on the correct volume to be administered, based on the calculated dose.
  4. Instruct the caregiver or child to take the Ceftazidime (Fortaz) oral suspension orally, ensuring they receive the full dose.
  5. Emphasize the importance of taking the prescribed dosage as directed by the healthcare provider and adhering to the specified frequency and timing.
  6. Store the Ceftazidime (Fortaz) oral suspension in a cool, dry place, following the medication’s storage instructions.

Dosing Precision and Medication Safety

Accurate calculation and administration of Ceftazidime (Fortaz) are critical for the successful treatment of pediatric patients. Healthcare professionals must ensure that the prescribed dosage and preparation instructions are followed accurately to provide pediatric patients with the right amount of Ceftazidime for effective treatment, while minimizing the risk of complications.


Precise determination and administration of Ceftazidime (Fortaz) dosage are vital for effective treatment in pediatric patients. By adhering to healthcare provider prescriptions and considering factors such as the prescribed dose, Ceftazidime concentration, and dosing frequency, healthcare professionals can ensure that pediatric patients receive the right amount of Ceftazidime, ultimately contributing to their recovery and overall well-being.
