WHAT YOUR FACTOR IX LEVELS SAY ABOUT YOUR TREATMENT
Your factor levels indicate how well you’re protected from bleeds and joint damage. In general, the higher the factor level, the less likely you are to experience a bleed.
WHY IT’S IMPORTANT TO PAY ATTENTION TO TROUGH LEVELS
Your factor levels will vary between infusions, ranging from peak to trough.
Peak levels occur right after an infusion
Trough represents your factor levels at their lowest
IS YOUR TROUGH FACTOR LEVEL HIGH ENOUGH TO KEEP YOU PROTECTED?
3. Select your trough factor level:
Before infusing, my factor levels are usually around
A treatment that keeps your trough factor levels high will help prevent bleeds and joint damage.
With FIX levels below <5% a bleed is more likely to occur
Joint bleed protection is cut by nearly a third when trough FIX levels drop from 5% to 1%
With FIX levels below >10% a bleed is more likely to occur
With FIX levels below >15% a bleed is more likely to occur
No expected joint bleeds in people with trough FIX levels >15%
ARE YOU READY TO DEMAND MORE FROM YOUR HEMOPHILIA B TREATMENT?
Advancements in therapy mean better hemophilia B protection. If you’re having spontaneous bleeds or wish you could stay protected with fewer infusions, it’s time to talk to your doctor about your treatment options.
