How long does Sustol work to prevent chemotherapy nausea?

Sustol (generic name: granisetron) has a polymer-based drug delivery system to maintain therapeutic levels of granisetron for 5 days or longer, covering both the acute and delayed phases of chemotherapy-induced nausea and vomiting (CINV).

Sustol is an extended-release, injectable 5-HT3 antagonist for the prevention of CINV due to certain cancer treatments. Sustol is used together with other anti-nausea medications. It is given as an injection under your skin by your healthcare provider.

Sustol is administered on Day 1 of chemotherapy. Do not use more frequently than once every 7 days because of the extended-release properties of the medicine.
