Xgeva (denosumab) is a prescription drug that’s used to treat some kinds of cancer. Xgeva comes as a solution inside prefilled, disposable pens that’s injected under the skin. It’s usually given once every 4 weeks.

Xgeva is used to:

  • prevent serious bone problems in adults with multiple myeloma or cancerous solid tumors that have spread to bone
  • treat giant cell tumor of bone that can’t be operated on in adults and in adolescents whose bones have finished growing
  • treat hypercalcemia (high calcium levels) in adults that’s caused by cancer and doesn’t respond to treatment with bisphosphonates (a group of drugs that’s used for certain bone problems)

The active ingredient in Xgeva is denosumab.

Xgeva belongs to a group of drugs called RANK ligand inhibitors. It’s sometimes called a bone-modifying agent.

This article describes the dosages of Xgeva, including its form, strength, and how the drug’s given. To learn more about Xgeva, see this in-depth article.

On days 8 and 15 of the first month of treatment, you’ll receive another 120-mg injection.

What’s the dosage of Xgeva for children?

Below are answers to some commonly asked questions about Xgeva.

Can Xgeva injections be given once every 3 months?

No, Xgeva is not given every 3 months. Xgeva injections are given every 4 weeks to help prevent serious bone problems.

Xgeva can be used to treat cancerous solid tumors that have spread to bone. Zoledronic acid is a drug that’s used to treat breast cancer that has spread to bone. This drug may be given every 3 months instead of every 4 weeks, if approved by your doctor.

But zoledronic acid is a different kind of drug than Xgeva. These drugs have different doses and amounts of time needed between injections. Make sure to not change your treatment or Xgeva dosage without first talking with your doctor.

Is Xgeva used to treat osteoporosis? If so, what’s the dosage?

No, Xgeva is not approved to treat osteoporosis (weakened bones).

Xgeva contains the active ingredient denosumab, which is also the active ingredient in a different drug called Prolia. Prolia is approved to treat osteoporosis. Although Xgeva and Prolia have the same active ingredient, they have different uses and dosages. These drugs should not be taken together.

Xgeva is given by a doctor or healthcare professional as an injection under your skin. It may be injected into your abdomen, upper arm, or upper thigh. It’s not approved for injection into a vein, muscle, or just below the skin’s surface.

For information on Xgeva expiration, storage, and disposal, see this article.

If you miss an appointment to receive an Xgeva injection, call your doctor to reschedule as soon as possible. It’s important to get an injection of Xgeva every 4 weeks. It might be helpful to schedule your next dose before you leave each appointment.

To help remember appointments, you could set a reminder on your phone or mark your injection schedule on a calendar.

The sections above describe the typical dosages provided by Xgeva’s manufacturer. If your doctor recommends Xgeva for you, they’ll prescribe the dosage that’s right for you.

Remember, you should not change your dosage of Xgeva without your doctor’s recommendation. Only take Xgeva exactly as prescribed. Talk with your doctor if you have questions or concerns about your current dosage.

Here are some examples of questions you may want to ask your doctor:

  • Should my dosage change if I start having side effects from Xgeva?
  • Does my dosage of Xgeva change if I’m taking other medications at the same time?
  • If I have liver problems or kidney problems, will I need an adjusted Xgeva dosage?

Q:

Will my doctor change my Xgeva dosage if my calcium levels decrease during treatment?

Anonymous

A:

No, your doctor likely won’t change your Xgeva dosage if your calcium levels decrease while you’re taking the drug.

They’re more likely to recommend that you take more calcium and vitamin D supplements. Your doctor might prescribe these supplements at the same time as Xgeva, to help prevent hypocalcemia (low calcium levels). But if your calcium levels become severely low during treatment, your doctor may recommend that you be treated at a hospital.
