How does this medication work? What will it do for me?
Pamidronate belongs to the family of medications known as bisphosphonates. It is used to treat hypercalcemia (high blood calcium) in people who have cancer. Pamidronate is also used to treat cancer that has spread to bones (bone metastases) due to different types of tumours and multiple myeloma (cancer of the bone marrow). Pamidronate is also used to treat the symptoms of Paget's disease of bone.
This medication works by reducing the breakdown of bone.

How should I use this medication?
The dosage of this medication depends on the condition that is being treated.
For hypercalcemia due to cancer (high calcium levels in the blood), the recommended total dose of pamidronate per treatment course will depend on the starting levels of calcium in the blood. The recommended maximum dose per treatment course is 90 mg, which can be given as a single intravenous (into the vein) infusion of 90 mg or multiple infusions spread over 2 to 4 days.
For bone metastases and multiple myeloma, the recommended dose of pamidronate is 90 mg given as a single-dose intravenous infusion every 4 weeks. The dose should be given over a period of 2 to 4 hours. People who receive chemotherapy every 3 weeks may receive 90 mg of pamidronate every 3 weeks.
For Paget's disease of bone, the recommended dose of pamidronate ranges from 180 mg to 210 mg given as intravenous infusions. The initial dosing schedule may be either 6 doses of 30 mg once a week (total dose 180 mg), or 30 mg for the first dose and 3 doses of 60 mg every second week (total dose 210 mg). Once this dosing schedule is complete, it can be repeated after 6 months. For repeat dosing, pamidronate is usually given as 3 doses of 60 mg every second week (total dose 180 mg).
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications.
It is important that this medication be given exactly as recommended by your doctor. If you miss an appointment to receive pamidronate, contact your doctor as soon as possible to reschedule your appointment.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Atypical femur fracture: There is evidence that long term use of this class of medication may contribute to a type of rare fracture of the long bone in the thigh (femur).
If you experience new or unusual pain in the groin, hip, or thigh area, contact your doctor as soon as possible.
Bone, joint, and muscle problems: On rare occasions, people taking this medication experience severe bone, joint, or muscle pain. This is usually reversed when the medication is stopped.
Deterioration of the jawbone: People with cancer treated with pamidronate (or other bisphosphonates) may rarely develop osteonecrosis of the jaw (deterioration of the jaw bone). If you experience any pain, swelling, or infection of the jaw, report this to your doctor. Before starting treatment with pamidronate, your doctor may recommend that you see a dentist for an examination and any necessary dental treatment. While receiving pamidronate, people should avoid invasive dental procedures such as tooth extractions.
Drowsiness/reduced alertness: Pamidronate may cause drowsiness and dizziness. Avoid driving, operating potentially dangerous machinery, or participating in other activities that may be hazardous until you know how this medication affects you.
Heart disease: Treatment with pamidronate usually requires intravenous fluids to be given before the medication, to ensure that your kidneys will be able to effectively remove the medication from the body. This extra fluid may cause extra work for the heart to move the blood through the body, leading to symptoms of congestive heart failure. If you experience symptoms such as difficulty breathing, swelling in the ankles, legs, or hands, or chest pain while receiving the fluids or medication, let your doctor know immediately.
Some people experience an irregular heartbeat with the use of pamidronate. If you experience a rapid, pounding heart beat, dizziness or fainting, or difficulty breathing while receiving this medication, let your doctor know right away.
If you have any type of heart condition, including high blood pressure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney problems: Decreased kidney function and kidney disease may cause pamidronate to build up in the body, leading to side effects. If you have reduced kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. You doctor will monitor your kidney function during and after intravenous infusions of pamidronate.
Pamidronate may also cause decreased kidney function. If you experience symptoms of decreased kidney function, such as change of urine colour, decreased urine production, swelling, fatigue, or abdominal pain, contact your doctor as soon as possible.
Low calcium levels: Pamidronate may cause low calcium levels. You will need to have regular blood tests while taking pamidronate to monitor your calcium levels. Your doctor may recommend taking calcium and vitamin D supplements while you are being treated with pamidronate, to ensure there is enough calcium in your blood.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if pamidronate passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.
