Specific Precautions and Warnings With ZanosarSome warnings and precautions to be aware of prior to using this medication include the following:
- Zanosar can cause severe and potentially life-threatening kidney problems, especially when used in high doses and over extended periods. Your kidney function will be monitored with blood and urine tests before, during, and after treatment. Your healthcare provider may lower your dose or recommend you stop using the medicine if you show signs of kidney damage. Make sure to drink plenty of fluids to stay hydrated during treatment, as this may help reduce your risk for kidney toxicity.
- In animal studies, some rats developed tumors or cancer when exposed to Zanosar.
- This medication can be irritating to the skin. You may develop a skin reaction at the injection site, especially if the medication leaks from your vein to the surrounding tissue. Let your healthcare provider know right away if you develop any reactions at the injection site, such as:
- Some people have developed confusion, extreme sleepiness, lack of energy (lethargy), and depression from this medication. These side effects could interfere with your ability to drive or operate heavy machinery. Therefore, you should avoid these activities until you know how the drug affects you, especially on days you receive your dose.
- Zanosar can cause liver problems and bone marrow suppression (when the bone marrow does not make adequate amounts of blood cells). Therefore, your healthcare provider will monitor your liver function and your blood cell counts throughout treatment, usually at least once a week. Make sure to keep all of your laboratory and healthcare provider appointments.

Your healthcare provider will weigh the risks and benefits of using this medicine before making a recommendation for your treatment.
