If your doctor has prescribed you Xgeva, you may have questions about it. Below are some common questions about the drug.

How long does Xgeva stay in your system?

Xgeva starts working in your body after it’s injected. Its effects continue for about 4 weeks afterward. At that point, about half of the drug remains in your system. This is when you’ll usually receive the next dose to maintain the drug’s effect.

If you don’t receive another dose of Xgeva, the amount of drug in your body will reduce by half after another 4 weeks. This continues until there is no more drug in your body. The drug stays in your body for about 140 days.

Other factors can affect how quickly your body gets rid of medications, such as Xgeva. These include how well your kidneys and liver work and your diet and body weight.

What’s Xgeva’s dosage for breast cancer?

Xgeva is not approved to treat breast cancer. However, it is approved to treat bone metastasis (cancer that’s spread to the bones). This includes metastatic breast cancer.

If you have bone metastasis due to breast cancer, your doctor may prescribe 120 mg of Xgeva once every 4 weeks. For this use, your doctor may recommend taking vitamin D and calcium supplements with Xgeva to treat or help prevent low blood calcium levels. Xgeva can cause low calcium levels as a side effect.
