What XIAFLEX is used for
XIAFLEX is used for the treatment of Dupuytren's contracture in adult patients with a palpable cord.
Dupuytren's contracture is a disease that causes your finger(s) to bend inward. This bending is called a contracture and is
caused by the abnormal formation of a cord(s) containing collagen under your skin.
For many people, a contracture causes significant difficulties with performing everyday tasks like driving, shaking hands,
playing sports, opening jars, typing or holding objects.
How it works
XIAFLEX is injected directly into the palpable cord(s) by your doctor and works by breaking down the collagen in the cord(s)
and thereby helps to remove the cause of your contracture so that your finger(s) can straighten.
The active substance is collagenase clostridium histolyticum, and is naturally produced by a bacterium named Clostridium histolyticum.
Before you are given XIAFLEX

1.You have an allergy to collagenase clostridium histolyticum or any of the ingredients listed at the end of this leaflet.

wide spread redness or rash,
tightness in the throat or difficulty breathing
2.You have taken anticoagulation medicine within the last 7 days.
One exception is the use of up to 150mg daily dose of acetylsalicylic acid (also called aspirin, a substance present in many
medicines used to prevent blood clotting) which can be taken.

to 150mg daily dose of acetylsalicylic acid (also called aspirin, a substance present in many medicines used to prevent blood
clotting) which can be taken.

How XIAFLEX is given
Your doctor will perform all injections of XIAFLEX. XIAFLEX should only be used by an approved practitioner who will be able
to display (or show you) such an authorisation.
This medicine must only be injected into the collagen cord in your hand by your doctor. Up to two cords or two affected joints
in the same hand can be injected at the same time during a treatment visit. Two palpable cords affecting two joints may be
injected or one palpable cord affecting two joints in the same finger may be injected at two locations during a treatment
Your doctor will take care to avoid injecting into tendons, nerves or blood vessels.
Incorrect injection into tendons, nerves or blood vessels may result in bleeding or damage and possible permanent injury to
If your cord(s) to be treated is attached to the skin, you are at higher risk of the skin splitting or tearing during the
finger(s) extension procedure following the injection of XIAFLEX. This will usually be treated by applying a dressing. In
severe cases a skin graft may be required.
How much is given
Each vial of XIAFLEX and sterile solvent for reconstitution should only be used for a single injection. If cords of two affected
joints on the same hand are to be treated during a treatment visit, separate vials and syringes should be used for each reconstitution
The recommended dose of your prescribed medicine is 0.58mg.
The total volume of the injection depends on the joint(s) being treated.
Your doctor will carefully select an area where the collagen cord(s) is best accessible and will proceed with the injection
into the cord(s).
If you take too much (overdose)
As this product is administered to you by your doctor it is very unlikely that you will be given an incorrect dosage. In the
unlikely event that your doctor administers a higher dosage than recommended, you may experience an increase in the severity
of possible side effects especially reactions at the injection site listed under "Side Effects" in this Leaflet.
You can telephone your doctor or the Poisons Information Centre on 13 11 26 for advice on overdose management.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
Clinical study experience with XIAFLEX is currently limited to up to 3 injections per cord at approximately 4 weeks interval.
After having XIAFLEX
Things you must do
Be sure to ask your doctor when you can resume normal activities after treatment with XIAFLEX.
After the injection, your doctor will place a dressing on your hand. You must limit motion of the treated finger(s) for a
day and it is not uncommon for the finger(s) to straighten on its own for some patients.
Until advised by your doctor, do not flex or extend the fingers of the injected hand.
Do not attempt to disrupt the injected cord(s) by self-manipulation at any time.
Elevate the injected hand as much as possible until bedtime.
Your doctor will ask you to return 24 to 72 hours after your injection to attempt to extend your finger(s) to straighten it.
Following extension of your finger, your doctor will fit you with a splint to wear at bedtime for up to 4 months.
It is recommended to avoid strenuous activities of your treated hand until instructed further by your doctor.
Your doctor may recommend you perform a series of finger flexion and extension exercises several times a day for several months
when you are ready.
Keep follow-up appointments with your doctor.
If your finger(s) is/are still not able to straighten during a follow-up visit with your doctor, you may need additional treatments
with XIAFLEX which may be administered approximately 4 weeks after the first treatment.
Injections and finger extension procedures may be administered up to 3 times per cord at approximately 4-week intervals.
If the disease has resulted in multiple contractures, additional cords maybe treated at other treatment visits approximately
4 weeks apart as determined by your doctor.
Tell your doctor immediately if:
symptoms of infection (fever, chills, increased redness or swelling) appear
symptoms of tendon rupture (trouble bending the finger after swelling goes down or altered sensation in the treated finger)
Tell your doctor if symptoms of musculoskeletal syndrome (joint or muscle pain, joint stiffness, shoulder stiffness, hand
swelling, fibrosis of the palms, and thickening or nodule forming of tendons) appear.
Serious allergic reactions and musculoskeletal syndrome are rare but serious side effects which require immediate medical
Things to be careful of
Be careful driving or operating machinery until you know how XIAFLEX affects you.
Swelling and pain which may impair the use of the treated hand and dizziness, numbness or altered sensation, and headache
have been reported as side effects immediately after injection of XIAFLEX.
You must avoid potentially hazardous tasks such as driving or using machines until it is safe to do so or as advised by your

itching in the hand or skin

Do not be alarmed by this list of possible side effects.
You may not experience any of them.
This is not a complete list of all possible side-effects. Others may occur in some people and there may be some side-effects
not yet known.
You may experience serious side effects which need urgent medical attention. Serious side effects are rare.
If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
sudden signs of allergy such as:
widespread redness or rash
swelling of the face, lips, throat or other parts of the body
tightness in the chest, shortness of breath or difficulty breathing.
Contact your doctor if you have trouble bending the injected finger(s) after the swelling has subsided as it may be a symptom
of tendon rupture.
These are very serious side effects. You may need urgent medical attention or hospitalisation.
As with any non-human protein medical product, the potential long term risk of autoimmune disease cannot be excluded.
All of these side effects are rare.
Other side effects not listed above may occur in some patients. Tell your doctor or pharmacist if you notice anything that
is making you feel unwell.
