Xiaflex injection is an enzyme used for the treatment of fixed flexion contracture called Dupuytren's contracture with a palpable cord.
Peyronie's disease with the drug is to be given only by or under the supervision of your healthcare professional.
2 What to Know Before Using
Before using Xiaflex, you must know all about the risks and complications associated with it. Inform your healthcare provider for any allergic reactions to these drugs or any other drugs, foods, dyes, preservatives, or animals.
Carefully read the label of non-prescription drugs for any possible allergic reaction or contraindications.
Studies in the pediatric population on the correlation of age to the effects of collagenase clostridium histolyticum injection have not been performed while safety and efficacy have not been established.
Studies in the elderly have not reported any geriatric-specific problems that would limit the utility of collagenase clostridium histolyticum injection.
Drugs should not be taken together to prevent any interactions but in necessary cases inquire your healthcare provider regarding the adjustments in dosage or any other necessary precautions to prevent any unwanted side effects.
Inform your healthcare professional if you are taking any other prescription or non-prescription drugs. Intake of specific food or using alcohol or tobacco with colistimethate is associated with an increased risk of certain side effects.
Your healthcare professional can give you special instructions about the use of food, alcohol, or tobacco. Inform your healthcare provider for any other medical problems such as blood clotting disorders, or Peyronie's plaque in the penile urethra.
Proper usage of Xiaflex requires strict adherence to your doctor’s orders. A trained healthcare professional will give you this drug in a hospital.
This drug is administered intravenously through a needle placed into the cord that is causing your finger to bend or into the plaque that is causing your penis to curve.
Follow the instructions on the label or as advised by your healthcare professional. Your affected hand will be wrapped with a bandage after receiving the injection if you are taking this drug for Dupuytren’s contracture.
Avoid making any unnecessary movement on the treated finger. Your healthcare professional may give you 2 injections if you have more than one contracture in the same hand.
It is very imperative that you return to your healthcare professional 1 to 3 days after receiving the injection. This will allow your healthcare professional to see the injected hand, and to do a possible finger extension procedure to disrupt the cord.
To prevent swelling, elevate the fingers of the injected hand until bedtime. To prevent more injury, refrain from moving or massaging the cord, bending, or extending the fingers of the injected hand, or doing a heavy activity using your hand.
Your healthcare professional may advise you to split your affected hand at bedtime for up to 4 months. Do finger bending and extending exercises as instructed by your healthcare professional.
For people with Peyronie's disease: This drug is available only through a restricted program called XiaflexВ® REMS Program.
Healthcare professionals who are enrolled in the restricted program can write a prescription for this drug. Your penis may be wrapped with a bandage after receiving the injection.
Your healthcare professional will tell you when to take the bandage off. This drug is given as part of a treatment cycle.
In a treatment cycle, you will receive an injection followed by a second injection 1 to 3 days later. It is very important that you return to your healthcare professional 1 to 3 days after your second injection.
This will allow your healthcare professional to do a manual procedure to stretch and help straighten your penis. Do not have sexual intercourse or have any sexual activity for at least 2 weeks after the second injection of a treatment cycle and after pain and swelling have gone away.
