reclast

Reclast (zoledronic acid - sometimes called zoledronate) is in a group of medicines called bisphosphonates (bis FOS fo nayts). Zoledronic acid inhibits the release of calcium from bones.

Reclast is used to treat Paget"s disease, and to treat or prevent osteoporosis in postmenopausal women or people who take certain steroid medicines. Reclast is also used to increase bone mass in men with osteoporosis.

The Zometa brand of zoledronic acid is used to treat high blood levels of calcium caused by cancer (hypercalcemia of malignancy). Zometa also treats multiple myeloma (a type of bone marrow cancer) or bone cancer that has spread from elsewhere in the body.

You should not be treated with Reclast if you are already receiving Zometa.

Important information

Reclast can harm your kidneys. This effect is increased when you also use other medicines harmful to the kidneys, such as: chemotherapy, antiviral medication, pain or arthritis medicine, injected antibiotics, or medicines to treat a bowel disorder or prevent organ transplant rejection. You may need dose adjustments or special tests if you use any of these medications. Do not receive Reclast without telling your doctor if you have had an allergic reaction to Reclast or similar medicine such as alendronate (Fosamax), etidronate (Didronel), ibandronate (Boniva), pamidronate (Aredia), risedronate (Actonel), or tiludronate (Skelid).

Do not use Reclast if you are pregnant. It could harm the unborn baby.

Your doctor may recommend you have a dental exam for preventive tooth and gum care before you start your treatment with Reclast. This is especially important if you have cancer, if you are undergoing chemotherapy or using steroids, or if you have poor dental health.

Some people using medicines similar to Reclast have developed bone loss in the jaw, also called osteonecrosis of the jaw. Symptoms of this condition may include jaw pain, swelling, numbness, loose teeth, gum infection, or slow healing after injury or surgery involving the gums. You may be more likely to develop osteonecrosis of the jaw if you have cancer or have been treated with chemotherapy, radiation, or steroids. Other conditions associated with osteonecrosis of the jaw include blood clotting disorders, anemia (low red blood cells), and pre-existing dental problems.

Before taking this medicine

You should not use Reclast if you are allergic to zoledronic acid.

You also should not use Reclast if you have:

• severe kidney disease; or

• low levels of calcium in your blood.

To make sure Reclast is safe for you, tell your doctor if you have:

• kidney disease;

• a history of thyroid or parathyroid surgery;

• malabsorption syndrome (an inability to absorb food and nutrients properly);

• a history of surgical removal of part of your intestine;

• asthma caused by taking aspirin;

• planned dental work or oral surgery;

• if you are dehydrated;

• if you take a diuretic ("water pill"); or

• if you are using other bisphosphonates (alendronate, etidronate, ibandronate, pamidronate, risedronate, Actonel, Fosamax, Boniva, and others).

In rare cases, Reclast may cause bone loss (osteonecrosis) in the jaw. Symptoms include jaw pain or numbness, red or swollen gums, loose teeth, or slow healing after dental work. The longer you use zoledronic acid, the more likely you are to develop this condition.

Osteonecrosis of the jaw may be more likely if you have cancer or received chemotherapy, radiation, or steroids. Other risk factors include blood clotting disorders, anemia (low red blood cells), and a pre-existing dental problem.

Your doctor may recommend you have a dental exam for preventive tooth and gum care before you start your treatment with Reclast. This is especially important if you have cancer, if you are undergoing chemotherapy or using steroids, or if you have poor dental health.

Do not use Reclast if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment.

Zoledronic acid can pass into breast milk and may harm a nursing baby. You should not receive Reclast if you are breast-feeding a baby.

How is Reclast given?

Reclast is injected into a vein through an IV. A healthcare provider will give you this injection.

Reclast is sometimes given only once per year. Follow your doctor"s instructions.

Your doctor may want you to take a calcium and/or vitamin D supplement while you are being treated with Reclast. Carefully follow your doctor"s instructions about the type and strength of calcium to take.

You may need frequent medical tests to help your doctor determine how long to treat you with Reclast. Your kidney function may also need to be checked.

You may not need to use Reclast for longer than 3 to 5 years if you use it for osteoporosis. Visit your doctor regularly.
