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:

  • loss of appetite or start losing weight (anorexia)
  • nausea or vomiting
  • feel tired
  • stomach pain or tenderness
  • dark urine or light colored stools
  • yellowing of your skin or the whites of your eyes
  • fever or rash

Heart muscle problems, including heart failure. Your doctor will check your heart function before starting Yondelis and during treatment. Tell your doctor immediately if you start having any of the following signs or symptoms:

  • chest pain
  • trouble breathing
  • swelling of your legs, ankles, or feet
  • feel like your heart is racing or fluttering

Leakage of Yondelis out of your vein during an infusion. Serious tissue damage can occur if Yondelis leaks out of your vein when you are receiving an infusion. Immediately alert your physician if you experience redness, itching, swelling, or pain at the site where you are receiving your infusion of Yondelis.

Allergic reactions. Some of these reactions were severe. Your healthcare provider may need to stop your treatment with Yondelis, and may give you medicines to treat the allergic reaction. Signs of an allergic reaction can include: difficulty breathing, chest tightness, wheezing, swelling of the lips, or skin rash.

Do not receive Yondelis if you are allergic to Yondelis or to any of its ingredients.
