XYNTHA

XYNTHA DUAL CHAMBER

XYNTHA is indicated for the control and prevention of haemorrhagic episodes in patients with haemophilia A, including control and prevention of bleeding in surgical settings. XYNTHA does not contain von Willebrand factor and should not be used by patients with von Willebrand’s disease.

XYNTHA dual chamber is the latest innovation from Pfizer. It’s the only haemophilia device in New Zealand that’s preloaded with both factor VIII and diluent for quick and convenient treatment.

Available in an all-inclusive kit, the XYNTHA dual chamber syringe features an innovative all-in-one convenient design that eliminates the transfer step for ease of reconstitution. XYNTHA, it’s ready to go when you are.

how to use xyntha?

Your routine, your dose.

Your treatment routine may be either:

  • Prophylaxis: you take XYNTHA on a regular basis so there is always factor in your system to help prevent bleeds.
or
  • On demand: you take XYNTHA when you have a bleed or just before you are exposed to risk (e.g. playing sport or an active trip away).

The dose you receive is calculated especially for you and can depend on:

  • How low your factor VIII levels are
  • Your clinical condition
  • If you have inhibitors
  • Your weight
  • Your response to treatment

Recording your infusions.

Every time you use a XYNTHA pack, it’s a good idea to record the name and batch number. Batch number labels on the vial can be peeled off and stuck in your diary.

However, there’s now a much easier way to record your infusions. Pfizer has created a web app called TRACKER FACTORy that’s especially designed for recording infusions as well as bleeds.

You can access this program by simply typing in www.trackerfactory.co.nz to any web enabled device such as your phone, iPad or desktop computer.

PREPARATION

  • Allow the XYNTHA dual chamber syringe to reach room temperature.
  • Always wash your hands before performing the following procedures.
  • Place components of the kit on a clean surface.
  • Use all components for the reconstitution and administration of this product as soon as possible after opening their sterile containers to minimise unnecessary exposure to the atmosphere.
  • Throughout the reconstitution process keep the XYNTHA syringe upright to prevent possible leakage.

Reconstitution Steps

Ready

A. Screw the plunger rod firmly into prefilled dual chamber syringe by pushing and turning firmly until resistance is felt.

Avoid contact with shaft of the plunger rod.

Set

A. Remove the white tamper-evident seal by bending the seal to expose the rubber tip cap.

 

B. Remove the grey rubber tip cap and replace it with the protective blue-vented sterile cap (prevents pressure build up).

Reconstitute

A. Gently advance plunger rod until the 2 stoppers inside meet and all the diluent is transferred to the chamber containing the XYNTHA powder.

C. Slowly advance the plunger rod until most, if not all, of the air is removed from the drug product chamber.

Please note: the solution should be clear to slightly opalescent and colourless. If it is not, the solution should be discarded and a new kit should be used.

 

B. Swirl gently several times until powder is dissolved.
