Xiaflex

Generic Name: collagenase clostridium histolyticum (kol-AJ-e-nase klos-TRID-ee-um HIS-toe-LIT-ik-um)
Brand Name: Xiaflex

If you are using Xiaflex to treat Peyronie disease:

  • Xiaflex may cause permanent damage to the tubes in the penis, causing them to break during an erection (corporal rupture or penile fracture). Xiaflex may also cause blood vessels in the penis to break, causing blood to collect under the skin. Contact your doctor right away if you experience a popping sound or sensation in an erect penis; sudden inability to maintain an erection; pain, bruising, or swelling of the penis; trouble urinating; or blood in the urine.
  • Xiaflex is only available for the treatment of Peyronie disease through a special program called Xiaflex Risk Evaluation and Mitigation Strategy Program (REMS). Talk to your doctor to be sure that you are enrolled in this program and that you meet all of its requirements.

Xiaflex is used for:

Treating Dupuytren contracture. It is also used to treat Peyronie disease.

Xiaflex is a collagenase enzyme. It works by helping to break down the collagen, which allows the fingers or penis to straighten.

Do NOT use Xiaflex if:

  • you are allergic to any ingredient in Xiaflex or to other collagenase products
  • the Peyronie plaque to be treated involves the urethra (the tube that urine passes through)

Contact your doctor or health care provider right away if any of these apply to you.

  • If you are using Xiaflex to treat Dupuytren contracture:
    • Limit motion of the treated finger and keep the treated hand elevated until bedtime.

    • Your doctor will give you exercises for the treated hand. Discuss any questions that you may have about these exercises with your doctor.
    • Rarely, some patients have had serious effects on tissues of the treated hand (eg, tendon or ligament problems, nerve problems, skin tears). Tell your doctor right away if you have numbness, tingling, increased pain, or breaks in the skin of the treated finger or hand after your injection or after your follow-up visit. Also tell your doctor if you have trouble bending your treated finger after the swelling goes down or if you have problems using the treated hand after your follow-up visit.
  • If you are using Xiaflex to treat Peyronie disease:
    • You may have mild bruising, pain, or swelling of the penis after the injection. Contact your doctor right away if this becomes worse or you experience trouble urinating, blood in the urine, popping or cracking sounds from the penis, or sudden loss in the ability to maintain an erection.
    • Do not have sex or have any other sexual activity for at least 2 weeks after the second injection of Xiaflex and after any pain and swelling has gone away.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Xiaflex while you are pregnant.
