Zoledronic Acid (ZOE-le-DRON-ik AS-id) Injection

Read the Medication Guide that comes with zoledronic acid injection before you start taking it and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking with your doctor about your medical condition or treatment. Talk to your doctor if you have any questions about zoledronic acid injection.

What is the most important information I should know about zoledronic acid injection?

You should not receive zoledronic acid injection if you are already receiving Zometa. Both zoledronic acid injection and Zometa contain zoledronic acid.

Zoledronic acid injection can cause serious side effects including:

1. Low calcium levels in your blood (hypocalcemia)
2. Severe kidney problems
3. Severe jaw bone problems (osteonecrosis)
4. Unusual thigh bone fractures
5. Bone, joint or muscle pain

1. Low calcium levels in your blood (hypocalcemia).

Zoledronic acid injection may lower the calcium levels in your blood. If you have low blood calcium before you start taking zoledronic acid injection, it may get worse during treatment. Your low blood calcium must be treated before you take zoledronic acid injection. Most people with low blood calcium levels do not have symptoms, but some people may have symptoms. Call your doctor right away if you have symptoms of low blood calcium such as:

• Spasms, twitches, or cramps in your muscles
• Numbness or tingling in your fingers, toes, or around your mouth

Your doctor may prescribe calcium and vitamin D to help prevent low calcium levels in your blood, while you take zoledronic acid injection. Take calcium and vitamin D as your doctor tells you to.

2. Severe kidney problems.

Severe kidney problems may happen when you take zoledronic acid injection. Severe kidney problems may lead to hospitalization or kidney dialysis and can be life-threatening. Your risk of kidney problems is higher if you:

• already have kidney problems
• take a diuretic or “water pill”
• do not have enough water in your body (dehydrated) before or after you receive zoledronic acid injection
• are of advanced age since the risk increases as you get older
• take any medicines known to harm your kidneys

You should drink at least 2 glasses of fluid within a few hours before receiving zoledronic acid injection to reduce the risk of kidney problems.

3. Severe jaw bone problems (osteonecrosis).

Severe jaw bone problems may happen when you take zoledronic acid injection. Your doctor should examine your mouth before you start zoledronic acid injection. Your doctor may tell you to see your dentist before you start zoledronic acid injection. It is important for you to practice good mouth care during treatment with zoledronic acid injection.

4. Unusual thigh bone fractures.

Some people have developed unusual fractures in their thigh bone. Symptoms of a fracture may include new or unusual pain in your hip, groin, or thigh.

5. Bone, joint, or muscle pain.

Some people who take bisphosphonates develop severe bone, joint, or muscle pain.

Call your doctor right away if you have any of these side effects.
