Preparation of XOFLUZA for Oral Suspension by Healthcare Provider
Prior to dispensing to the patient, constitute XOFLUZA for oral suspension with 20 mL of drinking water or sterile water. After constitution, each bottle of XOFLUZA suspension contains 40 mg of baloxavir marboxil per 20 mL of volume for a final concentration of 2 mg/mL. This dosage form can be used for oral or enteral use.
Constituting XOFLUZA for Oral Suspension
Prepare the suspension at the time of dispensing. Administration must occur within 10 hours after constitution because the product does not contain a preservative.
- Gently tap the bottom of the bottle to loosen the granules.
- Constitute XOFLUZA for oral suspension with 20 mL of drinking water or sterile water.
- Gently swirl the suspension to ensure that the granules are evenly suspended. Do not shake.
- Write the expiration time and date on the bottle label in the space provided (10 hours from constitution time).
Important Information for the Healthcare Provider
- Provide caregiver or patient with a measuring device (e.g., oral syringe, measuring cup) to deliver the prescribed dose of the suspension for oral use. For enteral administration (i.e., feeding tube), draw up suspension with an enteral syringe. Flush with 1 mL of water before and after enteral administration.
- Instruct the caregiver or patient that the total prescribed dose of XOFLUZA for oral suspension may require more than one bottle (e.g., for adults and adolescents weighing at least 80 kg).
Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances.
