Prolia Lawsuits: Essential Updates and Information

Prolia, a medication developed by Amgen, is prescribed for the treatment of osteoporosis in postmenopausal women. While it has proven effective for some, the drug has also been the subject of controversy due to its potentially harmful side effects. A number of patients have filed Prolia lawsuits in recent years, alleging that the medication caused them significant harm.

These lawsuits have focused on complications such as atypical femur fractures and osteonecrosis of the jaw, which are not only painful but can also be debilitating. In response to the rising number of legal actions, a Prolia class-action lawsuit has been filed against Amgen, the manufacturer of the drug. This has further heightened concerns about the safety of Prolia for patients seeking relief from osteoporosis symptoms.

Legal battles surrounding Prolia have grown more complex, with Amgen even suing Novartis to block generic versions of the drug used for treating osteoporosis and bone cancer. As the situation unfolds, patients, healthcare professionals, and the legal community will continue to scrutinize the safety and efficacy of Prolia for managing osteoporosis.

Prolia and Osteoporosis


Prolia, a medication developed by Amgen, is used to treat patients suffering from osteoporosis. Its active ingredient, denosumab, is a monoclonal antibody that inhibits the RANK ligand, a protein responsible for the activation of osteoclasts (bone-resorbing cells). By doing so, denosumab reduces bone loss and lowers the risk of fractures in those with osteoporosis.

Menopausal Osteoporosis

Menopausal osteoporosis is a common condition in postmenopausal women, where the decrease in estrogen levels leads to increased bone resorption and decreased bone mineral density. Prolia is specifically indicated for the treatment of postmenopausal women with osteoporosis who are at high risk for fractures. Clinical trials have shown that Prolia is effective in increasing bone mineral density and reducing the risk of vertebral, nonvertebral, and hip fractures in postmenopausal women with osteoporosis.

Bone Density

Prolia is known for its ability to improve bone density in patients with osteoporosis. As denosumab inhibits bone resorption, it leads to an overall increase in bone mineral density. This increased density reduces the risk of fractures in osteoporosis patients. Clinical studies have demonstrated the efficacy of Prolia in increasing bone mineral density at various skeletal sites, including the lumbar spine, total hip, and femoral neck, after both short-term and long-term use. Prolia’s benefits in managing osteoporosis, however, have in some cases led to lawsuits, as some patients have experienced severe injuries allegedly caused by the medication.

FDA Approval and Side Effects

Common Side Effects

Prolia, a medication developed by Amgen, was approved by the FDA in June 2010 to treat postmenopausal women with osteoporosis at high risk for bone fracture. It is also approved to treat men with osteoporosis. Some common side effects include back pain, pain in extremities, high cholesterol levels, and urinary tract infections. It is essential for patients to discuss these side effects with their healthcare provider and monitor their symptoms regularly.

Serious Side Effects

In addition to common side effects, Prolia has been linked to some severe side effects. One study published in North Carolina reported more than 40 serious cutaneous adverse events linked to the osteoporosis formulation of Prolia. Patients using Prolia may experience hypocalcemia—the severe lowering of calcium levels in the blood—which can potentially lead to life-threatening complications. To reduce the risk of hypocalcemia, patients should maintain adequate levels of vitamin D and calcium during the treatment.

Black Box Warning

There have been increasing concerns regarding the safety of Prolia. A consumer watchdog has petitioned the FDA to add a black box warning to Prolia’s label. A black box warning is the FDA’s strongest warning label, indicating significant risks associated with the drug. Health Canada and European regulators have also been monitoring the safety of Prolia.

Although Prolia has been effective in treating osteoporosis for some patients, it is crucial for individuals to be aware of potential side effects and follow recommendations provided by their healthcare providers.

Bone Fractures and Risks

Prolia is a medication used to treat osteoporosis in postmenopausal women. However, several Prolia lawsuit cases have been filed in recent years, with patients claiming the drug caused them serious harm, including various types of bone fractures and jaw-related complications.

Hip Fractures

One of the potential side effects of Prolia is an increased risk of hip fractures. This type of fracture is particularly devastating for older adults, often resulting in long-term pain, disability, and reduced quality of life. Hip fractures can also lead to further complications, such as blood clots and infections, due to the patient’s limited mobility during the healing process.

Atypical Femur Fractures

Some Prolia patients have reported experiencing atypical femur fractures. These fractures, which are distinct from typical fractures caused by osteoporosis, can occur with minimal or no trauma to the femur bone. Atypical femur fractures are concerning because they can be difficult to diagnose and treat, often resulting in significant pain and impairment for the patient.

Vertebral Fractures

After stopping Prolia treatment, some patients have experienced multiple vertebral fractures. These fractures can cause severe back pain, limited mobility, and height loss due to spinal compression. Vertebral fractures also increase the risk of complications such as nerve damage and spinal instability.

Osteonecrosis of the Jaw

In addition to bone fractures, Prolia has been linked to a condition called osteonecrosis of the jaw (ONJ). ONJ is a severe bone disease that occurs when a section of the jawbone becomes exposed and begins to die, causing significant pain, infection, and tooth loss. Patients undergoing Prolia treatment should be aware of this risk and discuss any concerns with their healthcare provider.

Lawsuits and Settlements

Class Action Lawsuit

A Prolia class-action lawsuit has been filed against Amgen, the manufacturer of the drug Prolia. The medication, commonly used to treat osteoporosis in postmenopausal women, has been linked to side effects that resemble the symptoms of the disease itself. The class-action lawsuit seeks to represent and compensate the patients affected by these adverse reactions.

Prolia Lawsuit

Multiple Prolia lawsuit cases have been filed in recent years. The drug is claimed to have caused serious harm to patients using it for the treatment of osteoporosis. Some of the main injuries associated with Prolia include atypical femur fractures and osteonecrosis of the jaw. These cases underscore the importance of understanding the potential risks associated with the medication before taking it for treatment.


At present, no known settlement in the Prolia class-action lawsuit has been reached. As the legal proceedings continue, patients impacted by the drug’s side effects may eventually receive compensation for their injuries and suffering. It is crucial for those affected by Prolia to keep up with the progress of the lawsuit, as developments in the case may lead to potential settlements or further legal actions.

Health Issues Related to Prolia


Prolia can increase the risk of serious infections in patients. As the drug works by suppressing the immune system, it has been linked to a higher susceptibility to infections, particularly in cancer patients receiving the medication for bone loss. These infections may include pneumonia, cellulitis, and urinary tract infections. It is advised for patients to consult their healthcare providers if they experience any symptoms of infection while using Prolia.

Joint Pain

Joint pain is another common side effect associated with Prolia. Patients may experience discomfort, stiffness, or swelling in their joints while taking the medication. These symptoms can significantly impact the patient’s quality of life, and it is vital to discuss any joint pain experienced with a healthcare professional to determine whether Prolia is the appropriate treatment option.

Muscle Pain

Muscle pain has also been reported by patients using Prolia. This side effect may manifest as aches, tenderness, or cramps in the muscles. Similar to joint pain, muscle pain can be debilitating for those affected and may require adjustments to the treatment plan to manage the symptoms adequately.

Back Pain

Back pain is another potential side effect of Prolia. This discomfort can range from a mild, persistent ache to sharp, severe pain that can restrict movement and daily activities. It is essential for patients to communicate any back pain to their healthcare provider to evaluate the severity of the symptom and determine if Prolia is still the best course of action for treating their condition.

While Prolia has shown to be an effective treatment for osteoporosis and other bone-related conditions, it is crucial that patients and healthcare providers are aware of the potential health issues related to its use. By knowing and understanding these risks, the patient and medical professionals can make well-informed decisions regarding treatment with Prolia and ensure the safety and well-being of the patient.

Prolia Alternatives and Market Competition


Xgeva is another drug developed by Amgen that has the same active ingredient as Prolia: denosumab. While Prolia is primarily used for treating osteoporosis, Xgeva targets bone cancer and bone metastases prevention. These two drugs offer alternatives for patients with different medical conditions but share a similar mechanism of action.

Bone-Strengthening Drugs

Besides Prolia and Xgeva, several other bone-strengthening drugs are available in the market, offering patients a range of options. Some of these drugs include antineoplastics, endocrine drugs, and monoclonal antibodies. By offering a variety of choices, the market competition ensures that patients can find a suitable medication tailored to their specific needs and health conditions.


In the pharmaceutical industry, biosimilars are essentially generic versions of branded biologic drugs. Novartis’s generic arm, Sandoz, has been developing biosimilar versions of Prolia and Xgeva, leading to a legal battle over drug patents. Biosimilars face rigorous clinical studies and assessments before approval to ensure that they maintain the same safety and efficacy as the original branded drug. The emergence of biosimilars presents a competitive environment that may result in lower prices and improved access to medications for patients.
