Before Using Zometa

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Zoledronic acid injection is not indicated for use in children.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of zoledronic acid injection in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution in patients receiving zoledronic acid injection.

Pregnancy

A nurse or other trained health professional will give you this medicine. This medicine is given through a needle placed in one of your veins. The medicine must be injected slowly, so your IV tube will need to stay in place for at least 15 minutes.

For hypercalcemia, this medicine is usually given only once. If your doctor decides that you need additional doses, you will receive the medicine again after at least 7 days have passed. This treatment will continue until your body responds to the medicine.

For bone cancer and multiple myeloma, this medicine is usually given every 3 to 4 weeks. This treatment will continue until your body responds to the medicine.

For osteoporosis, this medicine is usually given once a year and will continue until your body responds to the medicine.

You may also receive other medicines to help keep your body from losing too much fluid.

Your doctor may also give you vitamins containing Vitamin D and calcium. Tell your doctor if you are unable to take these supplements.

This medicine comes with a Medication Guide. It is very important that you read and understand this information. Be sure to ask your doctor about anything you do not understand.

Precautions While Using Zometa

It is very important that your doctor check your progress at regular visits after you have received zoledronic acid injection. If your condition has improved, your progress must still be checked. The results of laboratory tests or the occurrence of certain symptoms will tell your doctor if your condition is coming back and if a second treatment is needed. You will need a yearly dose of this medicine if you are being treated for postmenopausal osteoporosis, so check with your doctor regularly.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away.

It is important that you tell all of your doctors that you are receiving zoledronic acid injection, including your dentist.
