What is the Most Important Information I Should Know About Xiaflex for the Treatment of Peyronie’s Disease

XIAFLEX can cause serious side effects, including:

  1. Penile fracture (corporal rupture) or other s erious injury to the penis. Receiving an injection of XIAFLEX may cause damage to the tubes in your penis called the corpora. After treatment with XIAFLEX, one of these tubes may break during an erection. This is called a corporal rupture or penile fracture. This could require surgery to fix the damaged area. Damage to your penis might not get better after a corporal rupture.
    • After treatment with XIAFLEX, blood vessels in your penis may also break, causing blood to collect under the skin (hematoma). This could require a procedure to drain the blood from under the skin.

      Symptoms of corporal rupture or other serious injury to your penis may include:

      • a popping sound or sensation in an erect penis
      • sudden loss of the ability to maintain an erection
      • pain in your penis
      • purple bruising and swelling of your penis
      • difficulty urinating or blood in the urine

      Call your healthcare provider right away if you have any of the s ymptoms of corporal rupture or s erious injury to the penis lis ted above.

      Do not have s ex or have any other s exual activity for at leas t 2 weeks after the second injection of a treatment cycle with XIAFLEX and after any pain and swelling has gone away.

What is Xiaflex

XIAFLEX is a prescription medicine used to treat adult men with Peyronie’s disease who have a “plaque” that can be felt and a curve in their penis greater than 30 degrees when treatment is started.

It is not known if XIAFLEX is safe and effective in children under the age of 18.

Who Should Not Receive Xiaflex

Do not receive XIAFLEX if you:

  • have been told by your healthcare provider that the Peyronie’s plaque to be treated involves the “tube” that your urine passes through (urethra).
  • are allergic to collagenase clostridium histolyticum or any of the ingredients in XIAFLEX, or to any other collagenase product. See the end of this Medication Guide for a complete list of ingredients in XIAFLEX.

Talk to your healthcare provider before receiving this medicine if you have any of these conditions.
