What is the most important information I should know about Ospomyv?
If you receive Ospomyv, you should not receive other denosumab products at the same time.
Ospomyv can cause serious side effects including:
  • Increased risk of severe low calcium levels in your blood (hypocalcemia). Ospomyv may lower the calcium levels in your blood. If you have low blood calcium before you start receiving Ospomyv, it may get worse during treatment. Your low blood calcium must be treated before you receive Ospomyv. Talk to your doctor before starting Ospomyv. Your doctor may prescribe calcium and vitamin D to help prevent low calcium levels in your blood while you take Ospomyv. Take calcium and vitamin D as your doctor tells you to.
    If you have advanced chronic kidney disease (may or may not be on kidney dialysis), Ospomyv may increase your risk for severe low calcium levels in your blood, which could result in hospitalization, life-threatening events and death. A mineral and bone disorder associated with kidney disease called chronic kidney disease-mineral bone disorder (CKD-MBD) may increase your risk for severe low calcium levels in blood. Before you start Ospomyv and during treatment, your doctor may need to do certain blood tests to check for CKD-MBD.
    Most people with low blood calcium levels do not have symptoms, but some people may have symptoms. Call your doctor right away if you have symptoms of low blood calcium such as:
  • spasms, twitches, or cramps in your muscles
  • numbness or tingling in your fingers, toes, or around your mouth
  • Serious allergic reactions. Serious allergic reactions have happened in people who take denosumab products. Call your doctor or go to your nearest emergency room right away if you have any symptoms of a serious allergic reaction. Symptoms of a serious allergic reaction may include:
  • low blood pressure (hypotension)
  • trouble breathing
  • throat tightness
  • swelling of your face, lips, or tongue
  • rash
  • itching
  • hives
  • Severe jaw bone problems (osteonecrosis). Severe jaw bone problems may happen when you take Ospomyv. Your doctor should examine your mouth before you start Ospomyv. Your doctor may tell you to see your dentist before you start Ospomyv. It is important for you to practice good mouth care during treatment with Ospomyv. Ask your doctor or dentist about good mouth care if you have any questions.
  • Unusual thigh bone fractures. Some people have developed unusual fractures in their thigh bone. Symptoms of a fracture include new or unusual pain in your hip, groin, or thigh.
  • Increased risk of broken bones, including broken bones in the spine, after stopping, skipping or delaying Ospomyv. Talk with your doctor before starting Ospomyv treatment. After your treatment with Ospomyv is stopped, or if you skip or delay taking a dose, your risk for breaking bones, including bones in your spine, is increased. Your risk for having more than 1 broken bone in your spine is increased if you have already had a broken bone in your spine. Do not stop, skip or delay taking Ospomyv without first talking with your doctor. If your Ospomyv treatment is stopped, talk to your doctor about other medicine that you can take.
  • Serious infections. Serious infections in your skin, lower stomach area (abdomen), bladder, or ear may happen if you take Ospomyv. Inflammation of the inner lining of the heart (endocarditis) due to an infection also may happen more often in people who take Ospomyv. You may need to go to the hospital for treatment if you develop an infection.
    Ospomyv is a medicine that may affect the ability of your body to fight infections. People who have a weakened immune system or take medicines that affect the immune system may have an increased risk for developing serious infections. Call your doctor right away if you have any of the following symptoms of infection:
  • fever or chills
  • skin that looks red or swollen and is hot or tender to touch
  • fever, shortness of breath, cough that will not go away
  • severe abdominal pain
  • frequent or urgent need to urinate or burning feeling when you urinate
  • Skin problems. Skin problems such as inflammation of your skin (dermatitis), rash, and eczema may happen if you take Ospomyv. Call your doctor if you have any of the following symptoms of skin problems that do not go away or get worse:
  • redness
  • itching
  • small bumps or patches (rash)
  • your skin is dry or feels like leather
  • blisters that ooze or become crusty
  • skin peeling
  • Bone, joint, or muscle pain. Some people who take denosumab products develop severe bone, joint, or muscle pain.
Call your doctor right away if you have any of these side effects.
