Generic Name: collagenase clostridium histolyticum (KOL a JEN ase klos TRID ee um HIS toe LIT ik um)
Brand Names: Xiaflex
What is Xiaflex?
Xiaflex (collagenase clostridium histolyticum) is made from a mixture of proteins derived from a certain bacteria.
Xiaflex is used to treat Dupuytren's contracture in adults. This condition causes an abnormal thickening of the tissue in the palm of the hand. This condition may get worse over time and form a "cord" in your palm, causing a permanent bend in your finger.
Xiaflex may also be used for purposes not listed in this medication guide.
Before you receive Xiaflex, tell your doctor if you have a bleeding or blood clotting disorder, such as hemophilia.
Xiaflex can damage a nerve, tendon, or ligament in the hand the medicine is injected into. After the swelling from your injection goes down, call your doctor if you have numbness, tingling, increased pain, trouble bending your finger toward your wrist, or if you have new or worsened movement problems in your treated hand.
The day after your Xiaflex injection, your doctor will need to examine your hand to see if your condition has improved. Avoid any strenuous activity using the treated hand until your doctor tells you to resume normal activities.
Before receiving Xiaflex
You should not use Xiaflex if you are allergic to collagenase clostridium histolyticum.
Xiaflex can damage a nerve, tendon, or ligament in the hand the medicine is injected into. This damage can weaken your hand and may lead to a broken bone or other problems. Surgery may be needed to correct these conditions. Talk to your doctor if you are concerned about this risk.
To make sure Xiaflex is safe for you, tell your doctor if you have:
a bleeding or blood clotting disorder, such as hemophilia; or
if you take a blood thinner such as aspirin, prasugrel (Effient), or warfarin (Coumadin, Jantoven).
FDA pregnancy category B. It is not known whether Xiaflex will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.

It is not known whether collagenase clostridium histolyticum passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How is Xiaflex given?
Xiaflex is injected directly into the "cord" of the affected hand. A healthcare provider will give you this injection.
After your Xiaflex injection, do not touch or put pressure on the treated area of the hand for the rest of the day. Keep the treated hand elevated until bedtime.
The day after your Xiaflex injection, your doctor will need to examine your hand to see if your condition has improved. If you still have the cord, your doctor may try to break it by extending your treated finger.
Xiaflex is usually given once every 4 weeks and you may receive more than one injection at a time. Follow your doctor's dosing instructions very carefully.
You may need to wear a splint on your hand for a short time to keep your fingers straight, especially at night. You may also need to perform daily finger exercises. Follow your doctor's instructions.
Call your doctor if you have trouble bending the treated finger after the swelling goes down.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for your Xiaflex injection.
What happens if I overdose?
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
What should I avoid?
Until you visit your doctor the day after your injection, do not flex or extend the fingers of your treated hand. Doing so may cause the medicine to spread away from the treatment area, making it less effective.
Avoid any strenuous activity using the treated hand until your doctor tells you to resume normal activities.
