Pamidronate
About Pamidronate
Pamidronate is a specialised injection used to lower dangerously high calcium levels in the blood, which can happen with certain types of cancer. It is also prescribed to treat and prevent bone damage caused by breast cancer or multiple myeloma, as well as to manage Paget's disease of the bone. This medicine plays an important role in protecting your bones from breaking and reducing bone pain.
Because Pamidronate is given as an injection directly into a vein, you will receive it at a clinic or hospital rather than taking it at home. The frequency of your treatment depends on your specific condition, ranging from a single session to doses repeated every few weeks. Since it bypasses your stomach, you do not need to worry about taking it with food, but it is highly beneficial to stay well-hydrated and follow a diet rich in essential bone nutrients if advised by your doctor.
While receiving this treatment, you might experience mild, temporary side effects like a light fever, shivering, or some soreness where the medicine was injected. However, if you notice more severe symptoms such as muscle spasms, numbness around your mouth, or severe jaw pain, you must contact your doctor immediately.
Before starting your treatment, it is vital to tell your healthcare provider if you have a history of kidney issues, low blood calcium, or upcoming dental procedures. Do not take this if you have had a severe allergic reaction to similar bone medications in the past.
Certain medications, like strong antibiotics or water pills, can interact with Pamidronate and increase the risk of kidney strain. Always let your doctor know if you are pregnant, breastfeeding, or managing other chronic health conditions before starting your therapy.
Uses of Pamidronate
Medicinal Benefits
Pamidronate helps protect your bones, reduce complications associated with bone disease, and improve your overall quality of life. The key benefits of Pamidronate are as follows:
- Reduces bone pain: By slowing down bone destruction, Pamidronate helps ease chronic bone pain, allowing patients to move more comfortably and improve their daily quality of life.
- Prevents bone fractures: It strengthens bones weakened by cancer or Paget's disease, significantly lowering the risk of painful breaks and fractures.
- Lowers dangerous calcium levels: It rapidly and safely reduces high calcium levels in the blood, which helps relieve severe fatigue, nausea, confusion, and protects kidney function.

Habit Forming
Diet & Lifestyle Advise
- Stay well-hydrated: Drink plenty of water before, during, and after your treatment to help your kidneys flush out waste and protect them from damage.
- Monitor calcium and vitamin D intake: Depending on why you are receiving Pamidronate, your doctor may recommend taking daily calcium and vitamin D supplements, or conversely, limiting them if your calcium levels are too high. Always follow your doctor's specific advice.
- Maintain good oral hygiene: Brush and floss your teeth regularly, and visit your dentist before starting treatment. Excellent dental health helps reduce the risk of rare but serious jaw bone issues.
- Engage in safe, weight-bearing exercise: If approved by your doctor, light activities like walking can help support bone strength and mobility.
Special Advise
- Your doctor may suggest certain blood tests, like serum calcium, CBC, and kidney function tests, to check for any unpleasant effects.
- Bone density scans are used to check bone mineral density (BMD).
- Clinical monitoring of serum electrolyte concentrations may also be advised.
Patients Concern
Disease/Condition Glossary
Hypercalcemia: Hypercalcemia is when the calcium level in the blood is higher than normal. Too much calcium in the blood can weaken the bones, create kidney stones, and interfere with working the heart and brain. It is usually a result of overactive parathyroid glands. Symptoms include increased thirst and urination, stomach pain, nausea, bone pain, muscle weakness, confusion and fatigue.
Paget's disease: Paget's disease is a chronic disease of bone that disrupts the replacement of old bone tissue with new bone tissue, resulting in the new bone that is abnormally shaped, weak and brittle. It most commonly occurs in the pelvis, skull, spine, and legs. Symptoms include bone pain, joint pain (especially in the back, hips, and knees), headache, enlargement and bowing of the thighs (femurs) and lower legs (tibias), and enlargement of the skull in the area of the forehead.
FAQs
Pamidronate is used to treat Hypercalcemia in Malignancy, Paget’s disease, and Osteolytic bone metastases of breast cancer.
Pamidronate contains Pamidronate as an active ingredient, which works by inhibiting osteoclast bone resorption that causes bone breakdown.
Pamidronate helps regulate the calcium level in the blood. This maintains bone formation and also helps the body to reverse bone loss. Due to this, the number of cells that damage bones becomes comparatively less.
The frequency of Pamidronate administration depends on the condition being treated. Therefore, follow your doctor's instructions for the best results.
Pamidronate is not recommended for pregnant women as it may cause fetal harm. It is unknown whether Pamidronate is excreted in human milk. Therefore, if you are a breastfeeding mother, please inform your doctor before taking Pamidronate.
Yes, Pamidronate may cause hair loss, but this is not a common side effect. If you experience hair loss while taking Pamidronate, please inform your doctor.
Pamidronate is safe if used under the supervision of a doctor. Follow your doctor’s instructions carefully and inform your doctor if you experience any side effects.
Maintain a balanced diet rich in fruits, vegetables, lean proteins, and whole grains to support your overall health. Try to consume calcium and vitamin D in their diet as it helps make stronger bones and avoid everyday osteoporosis dangers. Regular exercise like weight-bearing exercises are important for maintaining bone health. Smoking can weaken bones, and excessive alcohol consumption can interfere with bone health. It's best to quit smoking and limit alcohol intake. Please consult your doctor if you have any concerns.
The common side effects of Pamidronate are injection site reactions, stomach pain, loss of appetite, nausea, vomiting, fever, headache, dizziness, mouth sores, constipation, and cough. If any of these side effects persist or worsen, please consult your doctor.
Pamidronate is given as an intravenous (IV) infusion, meaning it is slowly dripped directly into a vein. This must be done by a healthcare professional in a clinic or hospital. Talk to your doctor if you have questions about the infusion process.
It is best to avoid invasive dental procedures, like extractions or implants, during treatment because Pamidronate can increase the risk of a rare jaw bone problem. Have a dental exam before starting treatment, and tell your dentist you are using this medicine. Talk to your doctor about any planned dental care.
Drinking plenty of fluids helps protect your kidneys, as Pamidronate is cleared from your body through your urine. Staying hydrated helps prevent kidney strain and damage. Talk to your doctor about how much water you should drink.
Yes, it is very common to experience mild fever, chills, and muscle aches within the first three days after your infusion. These symptoms are usually temporary and go away on their own. Talk to your doctor if they become severe or do not improve.
Pamidronate does not cure bone cancer, but it helps manage symptoms, strengthen bones, and lower high blood calcium levels. For Paget's disease, bisphosphonate treatment like Pamidronate can induce long-term clinical remission by normalising abnormal bone remodelling. Talk to your doctor about what to expect from your treatment.
