IMPORTANT SAFETY INFORMATION

Patients treated with ZALTRAP have experienced serious side effects. Your doctor may adjust or stop your ZALTRAP treatment if you have these or other side effects:

  • Severe Bleeding (Hemorrhage). ZALTRAP can cause severe internal bleeding including bleeding of the digestive system, brain, or lungs. Signs and symptoms may include blood in the stool or urine, abdominal pain or lightheadedness.
  • Gastrointestinal Perforation. ZALTRAP can cause a hole in the stomach, esophagus, or intestines. Symptoms may include abdominal pain, vomiting, fever, and chills.
  • Wounds That Don’t Heal (Impaired Wound Healing). ZALTRAP can interfere with wound healing. Do not undergo surgery or medical procedures (including tooth extractions) without discussing first with your doctors, as ZALTRAP should not be used at least 4 weeks before or 4 weeks after surgery and until the wound is fully healed.
  • A Fistula Could Form in Your Body. This is an abnormal passage that forms from one part of the body to another.
  • Hypertension (High Blood Pressure) may develop or get worse. In clinical trials, over half of patients treated with ZALTRAP who developed high blood pressure requiring treatment developed it within the first 2 cycles of ZALTRAP treatment. Your doctor will monitor your blood pressure regularly during treatment. Take anti-hypertensive therapy as directed by your doctor. Signs of high blood pressure may include severe headache, lightheadedness, confusion or similar neurological disorders.
  • Arterial Thromboembolic Events (Blood Clots That Form in Arteries). Blood clots can form and travel to the brain and cause a stroke; or to the heart and cause severe chest pain or other heart damage.
  • Too Much Protein in The Urine (Proteinuria). This may be a sign of kidney damage. Your doctor will monitor your urine protein levels during treatment. Signs of severe proteinuria may include swelling of the feet, hands, face, or abdomen.
  • Low White Blood Cell Count. This could lead to serious infections. Your doctor will monitor your white blood cell count regularly during treatment. Fever may be a sign of low white blood cell count and serious infection. Check your temperature regularly during treatment and tell your doctor if you have a fever.
  • Severe Diarrhea and Dehydration. Severe diarrhea can occur, especially in patients 65 years of age and older. Severe diarrhea (including vomiting) takes fluids from the body and can lead to dehydration.
  • RPLS (Reversible Posterior Leukoencephalopathy Syndrome). This is a very rare but serious brain disorder. Signs and symptoms include headache, seizures, visual changes and changes in mental function. These symptoms usually stop or improve within days, but some patients experienced continuing changes in mental function or death.
  • Embryo-Fetal Toxicity. If you are pregnant or plan to become pregnant, tell your doctor. ZALTRAP can harm your unborn baby. If you are able to become pregnant, use effective birth control with ZALTRAP and for 1 month following the last dose.
