Common questions about Prolia

What's the difference between Prolia and Reclast?
Prolia (denosumab) and Reclast (zoledronic acid) are injections that can be used to treat or prevent osteoporosis. But they each work differently because Prolia is a monoclonal antibody (it may also be called a miscellaneous bone resorption agent) and Reclast is a bisphosphonate which means they have different side effects, other uses, tolerability, and effectiveness profiles. Both are prescription medicines. One of the main problems with Prolia is safely stopping it. Continue reading
Evenity vs Prolia: Which is right for you?
Evenity (romosozumab-aqqg) and Prolia (denosumab) are two injectable medications that help lower the risk of bone fracture. Continue reading
Does Prolia weaken your immune system?
Yes, Prolia does appear to weaken your immune system. Research has shown people who take Prolia are at an increased risk of serious infections leading to hospitalizations, including endocarditis and serious infections of the skin, abdominal, urinary tract, and ear. People administered concomitant immunosuppressant agents (such as prednisone or cyclosporine) or with impaired immune systems may be at an even higher risk. Continue reading
How do you give a Prolia injection?
Prolia is a prescription medicine injected under the skin (called a subcutaneous injection) and is given once every 6 months. You do not give Prolia to yourself. You will receive your Prolia injection from your healthcare provider at a their office or clinic. Continue reading
Does Prolia cause weight gain?
Prolia (denosumab) is not known to cause weight gain. Weight gain was not reported as a side effect in the clinical trials used to approve it. Even so, some people do notice the scale go up after they start treatment. When that happens, it is usually caused by fluid buildup (a side effect called peripheral edema) or by other changes happening in the body at the same time, such as menopause or moving less because of bone and joint pain. Continue reading
Xgeva vs Prolia. How do they compare?
Xgeva and Prolia are both brand names for the generic drug denosumab. Both are injectable preparations, both are made by Amgen, and both have similar side effects; but they differ in their indications, the way they are given, and their dosage. Continue reading
Does Prolia increase bone density?
Prolia (denosumab) does increase bone density. Prolia works by targeting a molecule called RANKL that osteoclasts need to work. By stopping RANKL from binding to its receptor Prolia reduces bone breakdown, bone loss, bone pain, and other bone complications. BMD was increased by 8.8% at the lumbar spine, 6.4% at the total hip, and 5.2% at the femoral neck in trials that measured BMD after three years of treatment with Prolia. Continue reading
Can you drink alcohol while taking Prolia?
While there are no known drug interactions between Prolia (generic name: denosumab) and alcohol, but you should check with your doctor first before you drink. Some research has shown that alcohol consumption may increase your risk of osteoporosis, a bone fracture or impaired healing after a fracture. Continue reading
