Typical dosage for Elrexfio
Elrexfio is injected under the skin by a trained healthcare professional on your oncology team, typically in a hospital or clinic setting.
- Starting dose (“step-up” dosing): During your first week of treatment, your oncologist will raise your dose over the course of a week.
- Day 1 dose: 12 mg injected once.
- Day 4 dose: 32 mg injected once.
- Day 8 dose: 76 mg injected once.
- Maintenance dose: Starting a week after the last dose, your oncologist will inject 76 mg under the skin once a week.
- If the medication works well for you for at least 6 months, your oncologist might lower your dose to 76 mg once every two weeks.
Your oncologist will also prescribe several medications before the first three doses to help prevent a serious side effect called cytokine release syndrome. These include dexamethasone and diphenhydramine (Benadryl).
