INDICATIONS

Tbo-filgrastim is indicated to reduce the duration of severe neutropenia in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia.

DOSAGE AND ADMINISTRATION

Dosage

The recommended dose of tbo-filgrastim is 5 mcg/kg per day administered as a subcutaneous injection. Administer the first dose of tbo-filgrastim no earlier than 24 hours following myelosuppressive chemotherapy. Do not administer tbo-filgrastim within 24 hours prior to chemotherapy [see WARNINGS AND PRECAUTIONS].

Daily dosing with tbo-filgrastim should continue until the expected neutrophil nadir is passed and the neutrophil count has recovered to the normal range. Monitor complete blood count (CBC) prior to chemotherapy and twice per week until recovery.

General Considerations for Administration

Tbo-filgrastim should be administered by a healthcare professional.

Visually inspect parenteral drug products for particulate matter and discoloration prior to administration. Do not administer tbo-filgrastim if discoloration or particulates are observed.

The prefilled syringe is for single use only. Discard unused portions.

Recommended sites for subcutaneous tbo-filgrastim injections include the abdomen (except for the two inch area around the navel), the front of the middle thighs, the upper outer areas of the buttocks, or the upper back portion of the upper arms. The injection site should be varied daily. Tbo-filgrastim should not be injected into an area that is tender, red, bruised, or hard or that has scars or stretch marks.
