What Exactly is Xiaflex?

Xiaflex is a biologic medication derived from natural enzymes known as collagenases. These enzymes break down excess collagen—a tough, fibrous protein that builds up abnormally in certain conditions.

It is FDA-approved for two conditions:

1. Dupuytren’s Contracture

• A disorder where thick, rope-like cords of tissue form in the palm of the hand.
• These cords pull one or more fingers into a bent position, making it difficult to straighten them.
• Over time, it can interfere with grip strength, hand function, and daily activities like writing, cooking, or even holding a steering wheel.

2. Peyronie’s Disease

• A condition in which scar tissue (plaque) forms under the skin of the penis.
• This leads to curvature, pain during erections, and sometimes erectile dysfunction.
• The condition can have a significant impact on both physical and emotional well-being, affecting self-esteem and intimate relationships.

Instead of relying on invasive surgery, Xiaflex offers a less disruptive treatment option. It is injected directly into the affected area, where it works to dissolve the collagen fibers responsible for the contracture or plaque. Over time, this can restore normal function and improve quality of life.

Xiaflex Strength and Formulation

One of the advantages of Xiaflex is that it comes in a standardized strength, ensuring consistency and precision in every dose.

• Form: Xiaflex is supplied as a freeze-dried powder in a single-use vial. Before injection, the powder must be mixed with a sterile diluent (a liquid provided in the package) to create the solution.
• Strength: Each vial contains 0.9 mg of active Xiaflex.
• Single-Use Vials: A fresh vial is used for each injection. Any leftover medication must be discarded immediately to prevent contamination.

This careful preparation ensures that every patient receives the most accurate and sterile treatment possible.

---

Dosage Guidelines for Different Conditions

Xiaflex dosage is condition-specific. The number of injections, spacing between treatments, and aftercare instructions differ between Dupuytren’s contracture and Peyronie’s disease. Your doctor will determine the right plan based on your condition and overall health.

---

Xiaflex Dosage for Dupuytren’s Contracture

When treating Dupuytren’s contracture, the goal is to weaken and dissolve the collagen cord that is pulling your finger into a bent position.

• Standard Dose: A single injection of 0.58 mg is administered directly into the cord of tissue.
• Frequency:
  • A cord can be treated with up to three injections.
  • Each injection must be spaced at least four weeks apart.
• Multiple Cords: If more than one cord is causing problems, your doctor may treat up to two cords in the same hand during one visit.

👉 Example: If you have two bent fingers caused by two cords, both can be injected in one appointment, but if one cord doesn’t respond after three attempts, surgery may be considered.

---

Xiaflex Dosage for Peyronie’s Disease

For Peyronie’s disease, treatment is a little more involved because scar tissue in the penis requires careful, gradual correction.

• Treatment Cycle:
  • Each cycle consists of two injections of 0.58 mg, given 1 to 3 days apart.
• Maximum Cycles:
  • A single plaque can be treated with up to four cycles.
  • Cycles are typically scheduled six weeks apart to allow healing.

👉 Example: If the curvature improves after two cycles, your doctor may stop further injections. If improvement is minimal, all four cycles may be recommended.

Unlike Dupuytren’s contracture, Peyronie’s treatment often requires patient participation in at-home exercises (stretching and straightening), making consistency crucial.

---

How Xiaflex is Administered

Xiaflex must always be given by a trained healthcare provider—never at home. The injection process and aftercare differ depending on the condition being treated.

---

Administration for Dupuytren’s Contracture

1. Injection Procedure:
   • The doctor injects Xiaflex directly into the collagen cord in your palm.
2. Bandaging:
   • Your hand is wrapped to limit movement, and you’ll be advised to keep it elevated until bedtime.
3. Follow-Up Appointment:
   • You return 1–3 days later. If the cord hasn’t broken naturally, the doctor may perform a finger extension procedure—a quick manipulation done after numbing your hand.
4. Aftercare:
   • A night splint is usually worn for about four months.
   • Hand exercises must be done daily to maintain flexibility and strength.

This combination of injection + manual extension + exercises often helps patients regain much of their lost hand function.

---

Administration for Peyronie’s Disease

1. Injection Procedure:
   • Two injections are given into the plaque, spaced 1–3 days apart.
2. Follow-Up Visit:
   • On your next appointment, your doctor may perform a penile modeling procedure, where they gently stretch and straighten the penis.
3. Aftercare:
   • For the next six weeks, you’ll be instructed to:
     • Stretch the penis gently three times daily.
     • Straighten it for 30 seconds once a day when the penis is not erect.
   • Sexual activity should be avoided for at least 4 weeks after each cycle.

Following these steps is crucial for maximizing results and preventing recurrence.

---

Managing Missed Doses or Appointments

Because Xiaflex is only given in a clinical setting, missing an appointment can delay your progress. If you forget or cannot attend:

• Call your doctor immediately to reschedule.
• Do not attempt self-injection under any circumstances.
• Use reminders, phone alarms, or a calendar app to keep track of upcoming visits.

Staying consistent is the best way to see long-term improvement.

How Long Does It Take for Xiaflex to Work?

One of the most common questions patients ask is, “How soon will I see results?” The timeline depends on whether you are being treated for Dupuytren’s contracture or Peyronie’s disease.

For Dupuytren’s Contracture

• Immediate Breakdown: In many cases, the collagen cord begins to weaken within 24 to 72 hours of the injection. Some patients even notice their finger starting to loosen before returning for their follow-up visit.
• Finger Extension Procedure: If the cord does not break on its own, the doctor can manipulate your finger during the follow-up visit. This is often the point where patients see the most dramatic improvement.
• Ongoing Recovery: With splinting and exercises, many patients regain long-term hand mobility within a few weeks, though stiffness may take longer to resolve fully.

For Peyronie’s Disease

• Slower Process: Peyronie’s treatment requires multiple cycles, so results take more time.
• Gradual Improvement: Some men notice a reduction in curvature after the first or second cycle, but most see significant changes after three to four cycles.
• Best Outcomes: Consistent stretching, modeling, and following doctor’s instructions are key. Patience is required—expect improvements to unfold gradually over several months.

👉 Real-life perspective: While some patients see early changes, the full benefit of Xiaflex often comes with time, commitment, and multiple treatment sessions.

---

What is the Maximum Xiaflex Dosage?

Your doctor will carefully monitor your treatment to ensure the safest and most effective dosage.

Maximum Dosage for Dupuytren’s Contracture

• Up to three injections per cord, spaced at least four weeks apart.
• Two cords can be treated in the same hand during one appointment.
• If a cord does not respond after three injections, your doctor may recommend alternative treatments, including surgery.

Maximum Dosage for Peyronie’s Disease

• A single plaque can be treated with up to four cycles (eight injections total).
• Each cycle includes two injections, given a few days apart.
• Cycles are spaced six weeks apart, making the maximum treatment course last several months.

👉 Important Note: These are maximum guidelines. Many patients need fewer injections and still achieve excellent results. Your doctor will stop treatment if your condition improves significantly before reaching the maximum limit.
