What Is Flutamide Used For?
Flutamide is used with a luteinizing hormone-releasing hormone agonist, such as leuprolide or goserelin, to treat certain prostate cancers. The companion medicine lowers androgen production, while flutamide blocks androgen activity at cells. A cancer clinician determines the treatment plan.
How Does Flutamide Work?
Androgens can stimulate the growth of prostate cancer cells. Flutamide blocks androgen receptors, reducing this stimulation. It does not lower androgen production on its own.
How Is Flutamide Taken?
Flutamide comes as an oral capsule that is usually taken three times a day. It can be taken with or without food. Continue the companion hormone treatment unless the cancer clinician changes the plan.
What Are Flutamide Side Effects and Precautions?
Diarrhea, hot flashes, breast enlargement, and reduced sexual desire can occur. Flutamide can also cause severe liver injury, so liver blood tests are needed before and during treatment. Report dark urine, yellowing of the skin or eyes, marked fatigue, or pain in the upper right abdomen promptly.
