It is very important that your doctor check your progress at regular visits, especially during the first few months of treatment with this medicine, since your dose may have to be adjusted. This is to make sure that this medicine is working properly and does not cause unwanted effects. Blood tests may be needed to check for unwanted effects.
Sometimes, you might have hypercalcemia (too much calcium in the blood) and not have any warning signs. You may need to have blood tests on a regular schedule while you are being treated with this medicine to check the amount of calcium and phosphorus in your blood. Keep all appointments your doctor makes for you.
If you have mild hypercalcemia, you may lose your appetite and have nausea, vomiting, or constipation. If the problem is severe, you may feel confused or extremely excited. Stop using this medicine and call your doctor right away if you think you might have severe hypercalcemia.
Do not take other calcium-containing products including dietary supplements and antacids. Your doctor may adjust the amount of calcium-containing foods you eat. Taking too much calcium while you are taking this medicine can cause hypercalcemia.
