Fulvestrant is given as two injections into a muscle of your buttock. A healthcare professional will give you this injection.
Each injection must be given slowly, and can take up to 2 minutes to complete.
Fulvestrant is usually given once every 2 weeks at first, and then once a month.
When treatment also includes taking abemaciclib or palbociclib, these medicines are taken by mouth and have daily dosing schedules. Also, palbociclib is taken with food while abemaciclib may be taken with or without food. Follow your doctor's dosing instructions very carefully.
Use all medications as directed and read all medication guides you receive. Do not change your dose or dosing schedule without your doctor's advice.
If you are a woman using fulvestrant with abemaciclib or palbociclib, tell your doctor if you are still going through menopause (you have symptoms such as irregular menstrual periods, hot flashes, night sweats, or vaginal dryness). You may need to be treated with an additional hormone medication.
