Yondelis Precautions

Serious side effects have been reported with Yondelis including the following:

Severe infections due to decreased white blood cells. Serious infections can occur with Yondelis due to a low number of white blood cells that typically fight infections. Your healthcare provider will perform blood tests to check your white blood cell count and may lower your dose or stop treatment with Yondelis completely if you develop this side effect. Call your doctor immediately if you develop signs of an infection such as a fever, chills, sore throat, or ongoing cough and congestion.

Rhabdomyolysis (severe muscle problems). Yondelis can cause serious muscle problems. Your doctor will perform blood tests to monitor your level of CPK, which can indicate muscle damage if high. Tell your doctor immediately if you experience any of the following signs or symptoms:

  • muscle pain
  • muscle weakness
  • dark urine
  • general weakness
  • decreased urine output

Liver problems, including liver failure. Tell your healthcare provider right away if you experience any of the following signs or symptoms of liver damage:

Yondelis and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

There have been no studies in pregnant women with Yondelis. Based on how Yondelis works, it can potentially cause serious harm to an unborn baby if given to a pregnant woman.

  • Women who are able to become pregnant should use an effective form of contraception during treatment with Yondelis and for at least 2 months after the last dose of Yondelis.
  • Males with female partners who are able to become pregnant should use an effective method of contraception (such as condoms) during treatment with Yondelis and for at least 5 months after the last dose.

Talk to your doctor about which method of contraception is best for you.

Yondelis and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if Yondelis crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, you should not breastfeed while on treatment with Yondelis.

Yondelis Usage

This medication is available as an injectable form to be given directly into a vein (IV) by a healthcare professional. The infusion is given over 24 hours through a central line (a type of IV line that goes into a vein in your chest, arm, or groin and ends in your heart) every 21 days.

Yondelis is typically given every 3 weeks. 

Your healthcare provider may decrease your dose or delay doses if you have certain side effects. If you have any side effects that are severe, your healthcare provider may stop your treatment with Yondelis. 

Before each infusion of Yondelis, your doctor will give you a steroid medicine to help reduce your risk of experiencing certain side effects.

Your doctor will determine the length of your treatment. 

If you miss an appointment to receive a dose of Yondelis, contact your healthcare provider immediately for instructions on when to receive your next infusion.

Yondelis Dosage

The dose of Yondelis your doctor recommends will be based on your body surface area (calculated from your height and weight). 

The recommended dose of Yondelis is 1.5 mg per m2 of body surface area (calculated from your height and weight) given as an intravenous (IV) infusion over 24 hours once every 3 weeks. Your doctor will determine your length of treatment based on your disease progression and any side effects you experience.

Your doctor will perform tests to monitor for side effects to Yondelis and may adjust your dose based on how you respond to this medication. If side effects become intolerable, you may need to wait longer between doses, receive a lower dose, or permanently stop the medicine if potentially serious side effects occur.
