Important Safety Information

Reclast (zoledronic acid) is an infusion medication used to treat Paget’s disease, multiple myeloma, any type of cancer that spreads to the bone, and high blood levels of calcium caused by cancer. It can also be used to treat or prevent osteoporosis in postmenopausal women — as well as to increase bone density.

Reclast may interact with other medications. Tell your doctor about all drugs you’re currently taking — whether they’re prescription, over-the-counter, vitamins, or herbal supplements. It may especially cause harm to your kidneys if mixed with diuretics, antibiotics, nonsteroidal anti-inflammatory drugs, antiviral medications, drugs to treat bowel disorders, cancer medications, and drugs to prevent organ transplant rejection.

Reclast will harm a fetus, but it is unknown whether the medication can be passed on to your baby via breast milk. Therefore, talk with your doctor about possible options if you are pregnant or breastfeeding, or are planning on breastfeeding.

What is the most important information I should know about Reclast?

Patients who are experiencing low calcium levels must treat such condition before starting treatment with Reclast, as the medication may worsen the condition. In addition, such patients may need to supplement with calcium and vitamin D. It may also be necessary to conduct bone density tests throughout treatment.

Reclast may be harmful to your kidneys — especially if you have experienced certain medical ailments in the past. Discuss your medical history with your doctor, particularly if you have a history of any of the following conditions:

  • Kidney disease
  • Dark-colored urine
  • Dry skin
  • Infections
  • Inability to drink enough fluids
  • Dehydration
  • Excessive or decreased sweating

Side Effects of Reclast

Patients who experience flu-like symptoms typically feel them after the first treatment — and they generally see an improvement within 48 hours. Less common side effects include heartburn, stomach ulcers, and swallowing difficulties. Alcohol will worsen symptoms of side effects.

In rare cases, Reclast may cause more serious side effects. Seek emergency medical care immediately if you experience any of the following symptoms:

Osteonecrosis of the jaw is more likely to occur in patients who undergo dental surgery while treating with Reclast. It can also occur if you’re undergoing chemotherapy, radiation treatments, or have a blood disorder.
