Is there a situation where I can receive more than 12 doses of Evenity?

No, it’s unlikely that you would receive Evenity for more than 12 doses.

Evenity works mainly by increasing the growth of new bone. But this effect diminishes after 12 monthly doses.

If you and your doctor decide that you still need treatment for osteoporosis after you’ve completed treatment with Evenity, your doctor will suggest a different osteoporosis treatment. For example, they may suggest that you transition to treatment with either Prolia (denosumab) injections or Fosamax (alendronate) oral tablets.

Your doctor can provide more information about your treatment plan should you need continued treatment after 12 doses of Evenity.

Each month you’ll receive two injections given by your doctor or other healthcare professional. The injections are given under the skin of your thigh, abdomen, or upper arm.

If you miss your scheduled appointment, call your doctor’s office as soon as you remember to reschedule.
