If you have osteoporosis or have a risk for bone loss, your doctor might suggest Prolia (denosumab) as a treatment option for you.

Prolia is a prescription medication that treats osteoporosis and reduces bone loss in certain people. Specifically, it’s used in the following adults who have a high risk for bone fractures:

  • females* with osteoporosis who’ve gone through menopause
  • males* with osteoporosis
  • males or females with osteoporosis who take corticosteroid medications long term
  • males who are receiving certain treatments that reduce male hormone levels for prostate cancer that hasn’t spread to other areas of the body
  • females who are receiving adjuvant treatment** for breast cancer with certain drugs that reduce female hormone levels

* In this article, we use the terms “male” and “female” to refer to someone’s sex assigned at birth. For information about the difference between sex and gender, see this article.
** Adjuvant treatment is used to help prevent cancer from coming back after it’s been treated in the past.

Drug details

Prolia comes as a liquid solution that’s given as an injection under your skin by your doctor.

Prolia contains the active drug denosumab. It belongs to a drug class called RANK ligand inhibitors. (A drug class is a group of medications that work in a similar way.)

Over time, Prolia can reduce bone loss and make your bones stronger. Your doctor may also have you take certain supplements that contain calcium and vitamin D while you’re receiving Prolia.

This article describes the dosage of Prolia, including its form, strength, and how to take the drug. To learn more about Prolia, see this in-depth article.

Anonymous patient

A:

Prolia works to reduce bone loss and lower your risk for having a fracture over time. You won’t feel the drug working in your body, but your doctor will monitor certain lab test results to check whether Prolia is working for you.

Specifically, your doctor will perform a bone mineral density test to measure your bone strength. Based on the results of this test, your doctor will determine if Prolia is effective for you.

If you have questions about whether Prolia is right for you, talk with your doctor.
