Indications and Important Safety Information
IMPORTANT SAFETY INFORMATION
If you receive OSENVELT, you should not receive other denosumab products at the same time.
OSENVELT can cause serious side effects including:
Serious allergic reactions. Serious allergic reactions have occurred with denosumab products. Call your doctor or seek emergency care immediately if you experience symptoms such as low blood pressure (hypotension), rash, difficulty breathing, itching, throat tightness, hives, or swelling of your face, lips, or tongue.
Low blood calcium (Hypocalcemia). OSENVELT can lower your blood calcium levels, which can become severe or even life-threatening. Your doctor will check your calcium levels before and during treatment, especially in the first few weeks. You may need to take calcium, magnesium, and vitamin D supplements as instructed by your doctor. Your risk may be higher if you have kidney problems or take other medicines that lower blood calcium. Call your doctor immediately if you experience symptoms of low blood calcium, such as muscle spasms or cramps, numbness or tingling in fingers, toes, or around your mouth, twitching or stiffness.
Severe jawbone problems (osteonecrosis). Severe jaw bone problems may happen when you take OSENVELT. Your doctor should examine your mouth before starting treatment and may advise seeing a dentist. Practice good oral care and consult your doctor or dentist if needed.
Unusual thigh bone fractures. Symptoms include new or unusual pain in your hip, groin, or thigh.
High Blood Calcium After Stopping Treatment. If you have giant cell tumor of bone or are still growing, stopping OSENVELT can lead to high calcium levels in your blood (hypercalcemia). This condition can become severe, require hospitalization, and affect your kidneys. Your doctor will monitor your calcium levels after stopping treatment. Call your doctor right away if you notice symptoms of high blood calcium, such as nausea or vomiting, increased thirst or urination, confusion or tiredness, muscle weakness or pain. Follow your doctor’s instructions carefully, and keep all scheduled appointments for calcium monitoring.
Multiple Spine Fractures After Stopping OSENVELT. After stopping treatment with OSENVELT, some patients have experienced multiple spine fractures. Your risk is higher if you have osteoporosis, previous fractures, or other risk factors. Your doctor will assess your individual fracture risk when stopping OSENVELT.
Risk to Unborn Babies. OSENVELT may harm your unborn baby if you take it while pregnant or within 5 months before becoming pregnant. Animal studies have shown serious harm, including pregnancy loss, birth defects, abnormal bone growth, missing lymph nodes, and slow growth after birth. Your doctor will check if you are pregnant before starting OSENVELT. Tell your doctor immediately if you become pregnant or think you may be pregnant during treatment.
