What is collagenase clostridium histolyticum?
Collagenase clostridium histolyticum is made from a mixture of proteins derived from a certain bacteria.
Collagenase clostridium histolyticum 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.
Collagenase clostridium histolyticum may also be used for purposes not listed in this medication guide.

Tell your caregiver at once if you have a serious side effect in the treated hand, such as bruising, bleeding, swelling, redness, warmth, numbness, tingling, or sudden pain or loss of movement.

How is collagenase clostridium histolyticum given?
This medication is injected directly into the "cord" of the affected hand. A healthcare provider will give you this injection.
After your 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 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.
Collagenase clostridium histolyticum 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 collagenase clostridium histolyticum injection.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

What should I avoid before and after receiving collagenase clostridium histolyticum?
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.
