It is important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.
Do not use this medicine together with alendronate (Fosamax®).
This medicine may increase your risk of having osteosarcoma (bone tumor). This is more likely to occur if you have Paget's disease of the bone, high levels of alkaline phosphatase, genetic disorders, children with open epiphyses, or a history of external beam or implant radiation therapy. Tell your doctor right away if you have bone pain that does not go away or a new soft tissue mass that is tender to palpitation.
Severe hypercalcemia (high calcium in the blood) may occur while using this medicine. This is more likely to occur when you start treatment or increase your dose. Call your doctor right away if you have confusion, constipation, dry mouth, metallic taste, muscle weakness, nausea or vomiting, or weight loss.
Do not stop using this medicine suddenly without asking your doctor. This may increase your risk of having severe hypocalcemia (low calcium in the blood). Symptoms include abdominal or stomach cramps, muscle spasms or twitching, numbness or tingling in your fingers, toes, or around your mouth, or trouble breathing.
Do not take other medicines unless they have been discussed with your doctor. Taking other medicines (especially digoxin, Lanoxin®) together with Natpara® may require your doctor to change the dose of one of the medicines.
