Ixabepilone can increase your risk of bleeding or infection. Call your doctor if you have unusual bruising or bleeding, or new signs of infection (fever, chills, easy bruising, unusual bleeding, burning when you urinate).

Ixabepilone is given as an infusion into a vein. A healthcare provider will give you this injection.

Ixabepilone is usually given every 3 weeks.

Ixabepilone must be given slowly, and the infusion can take up to 3 hours to complete.

About 1 hour before you receive ixabepilone, you may be given other medications to help prevent certain side effects.

Ixabepilone can increase your risk of bleeding or infection. You will need frequent medical tests. Your cancer treatments may be delayed based on the results.
