What is Xiaflex?

Xiaflex is an amalgamation of proteins that originates from a particular bacteria.

Xiaflex can be used to treat Dupuytren's contracture in adults. This condition leads to an abnormal thickening of tissues in the hand's palm. This condition could become more severe as time passes and may result in the appearance of a "cord" in your palm and an irreparable bend to your finger.

Xiaflex can also be utilised to treat a similar condition known as Peyronie's disease, which affects adult males. The condition results in scar tissue, or "plaque," developing under the penis's skin, which causes an irregular penis's curvature when erecting.

Xiaflex is available to treat Peyronie's disease only through an accredited pharmacy that is part of an exclusive programme called Xiaflex REMS. You must be enrolled in the programme and know the potential risks associated with taking this medication.


Before you take Xiaflex, inform your physician if you have bleeding or a blood clotting disorder like haemophilia.

Xiaflex could cause damage to a tendon, nerve, or ligament on the hand where the medication is. After the swelling of the injection has diminished, contact your physician if you experience numbness, discomfort, tingling, difficulty bending your fingers towards your wrist, or if you are experiencing newly developed or worsened problems with movement in the hand you've treated.

Xiaflex can also cause damage to the erectile tissues in the male penis, which could require surgery to fix. Consult your doctor now if you experience swelling and bruises on your penis, pain whenever you urinate, bloody urine in your urine, sudden problems with erection, or a "popping" sound or sensation inside your penis after an intimate session.

Details on dosage

Usual Adult Dose of Xiaflex for Dupuytren's Contracture:

0.58 mg is injected into a palpable cord to cause an enlargement of the metacarpophalangeal (MP) joint or an interphalangeal proximal (PIP) joint.
This drug must be administered by a medical professional who is skilled in injecting procedures for the hand as well as for the treatment of patients suffering from Dupuytren's contracture.
Up to two joints on the same hand could be treated in a single treatment visit. Two palpable cords that affect two joints could be injected. Alternatively, one cord with a palpable effect on two joints of the same finger can be injected at two locations during a treatment. If a patient is suffering from other palpable cords that have contractures of the MP or PIP joints, those cords can be injected at subsequent appointments, which are approximately 4 weeks apart.
Between 24 and 72 hours after an injection, an extension of the fingers is recommended in the event of a persistent contracture. Refer to the product's manufacturer's information or the local protocol to get information about the finger extension procedure.
Injections and procedures for finger extension are able to be administered up to three times per cord at about 4-week intervals.
Up to two cords in the same hand can be injected during a treatment visit. If the patient has additional cords that have contractures, these cords should be injected during a subsequent treatment appointment.

Usual Adult Dose of Xiaflex for Peyronie's Disease:

0.58 mg is injected into the plaque of interest once every two days, one to three days apart.
This medication should only be given by a medical professional skilled in the treatment of male urological disorders who has completed the required education for the treatment of peyronie's disease.
A treatment cycle comprises two injection procedures as well as penile modelling.
For each plaque that causes the curvature deformity, four treatment cycles can be given. Each treatment cycle can be repeated at approximately six-week intervals. If the curvature defect has less than 15° following the first, second, or third treatment cycles, or a further treatment isn't required, the subsequent treatment cycles should not be given.
The safety of more than one treatment option for the disease Peyronie's is not yet known.
