What NovoThirteen® is
NovoThirteen® contains the active substance catridecacog, which is identical to human coagulation factor XIII, an enzyme necessary for blood clotting. NovoThirteen® replaces
the missing factor XIII and helps to stabilise the initial blood clot by producing a mesh around the clot.
What NovoThirteen® is used for
NovoThirteen® is used to prevent bleeding in patients who do not have enough or are missing part of factor XIII (that is called A-subunit).

It is important that you use NovoThirteen® for injection immediately after preparation.
Do not use NovoThirteen®
• If you are allergic to catridecacog or any of the other ingredients of this medicine (listed in section 6).
If you are not sure, ask your doctor before using this medicine.
Warnings and precautions
Talk to your doctor before using NovoThirteen®:
• If you have or have ever had a higher risk of blood clots forming (thrombosis), as NovoThirteen® may increase the severity of a pre-existing blood clot.
• If you have or have ever had liver damage.
Contact your doctor immediately:
• If you experience bleeding during your treatment with NovoThirteen® occurring spontaneously and/or requiring treatment.
• If you experience an allergic reaction to NovoThirteen®. The signs may include: hives, itching, swelling, difficulty breathing, low blood pressure (signs include paleness and coldness of skin, rapid heartbeat), feeling dizzy and sweating.
Other medicines and NovoThirteen®
Tell your doctor if you are using, have recently used or might
use any other medicines.
It is not recommended to use NovoThirteen® and recombinant coagulation factor VIIa (another blood clotting factor) together.

NovoThirteen® contains sodium
This medicine contains less than 1 mmol sodium (23 mg) per injection, i.e. essentially ‘sodium-free’.

Your treatment with NovoThirteen® should be initiated by a doctor experienced in the treatment of rare bleeding disorders.
Always use this medicine exactly as your doctor has told you.
Check with your doctor if you are not sure.
Before you can use NovoThirteen® for injection you need to reconstitute the product. Please see NovoThirteen® user instructions.
NovoThirteen® is given as an injection into a vein. Your dose will depend on your body weight. The usual dose for prevention of bleeds is 35 IU for each kilogram of body weight. The injections are given once a month (every 28 ± 2 days).
If you experience a bleed, you should contact your doctor who will decide if an injection is needed.
NovoThirteen® should be injected at a rate not higher than 2 ml/minute.
Based on the concentration of NovoThirteen® solution, the dose volume to be injected (in millilitres) can be calculated from this formula:
Dose volume in millilitres = 0.042×your body weight in kilograms.
You should only use the prescribed dose calculated by your doctor from this formula considering that the usual dose and the concentration of NovoThirteen® are different from those of the other products which contain factor XIII.
Your doctor may adapt the dose if this is deemed necessary.
Use in small children
For children weighing less than 24 kg the reconstituted NovoThirteen® should be further diluted with 6 ml of sodium chloride 0.9%, solution for injection to be able to handle the dosing of small children. For more information see section ‘NovoThirteen® user instructions – Instructions of how to dilute the reconstituted NovoThirteen®’.
The dose volume for the reconstituted NovoThirteen® diluted with 6 ml sodium chloride 0.9%, solution for injection can be calculated from this formula:
Dose volume in millilitres = 0.117×body weight in kilograms.

Use in children and adolescents (weighing more than 24 kg)
NovoThirteen® can be used in children and adolescents in the same way as in adults for both prevention of bleeds and if you experience a bleed.
If you use more NovoThirteen® than you should
There is limited information on overdose with NovoThirteen®.
None of the reported cases have shown any signs of illness.
Contact your doctor if you have injected more NovoThirteen® than you have been instructed.
If you forget to use NovoThirteen®
If you forget an injection of NovoThirteen®, talk to your doctor. Do not take a double dose to make up for a forgotten dose.
If you stop using NovoThirteen®
If you stop using NovoThirteen®, you are not protected against bleeding. Do not stop using NovoThirteen® without talking to your doctor. Your doctor will explain what might
happen if you stop treatment and discuss other options with you.
If you have any further questions on the use of this medicine, ask your doctor.
