Konyne (factor IX complex) 80 is a clotting factor used to treat or prevent bleeding in people with hemophilia B. Some forms of factor IX complex may also be used to treat or prevent bleeding in people with factor VII deficiency or inhibitors to factor VIII. This medication is available in generic form. Common side effects include pain at injection site, chills, tingling, flushing, headache, nausea, or vomiting.

The dose of Konyne 80 required for normalizing hemostasis will depend upon the patient and upon the circumstances. Konyne may interact with other drugs that affect bleeding or blood-clotting processes. Tell your doctor all medications and supplements you use. During pregnancy, Konyne should be used only if prescribed. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.

Konyne in Detail - Patient Information: Side Effects

Factor IX complex is made from human plasma (part of the blood) and may contain infectious agents (e.g., viruses) that can cause disease. Although factor IX complex is screened, tested, and treated to reduce the possibility that it carries an infectious agent, it can still potentially transmit disease. Discuss with your doctor the risks and benefits of using factor IX complex.

Some viruses, such as parovovirus B19 and hepatitis A, may be more difficult to identify or remove from factor IX complex. Parovovirus B19 may more seriously affect pregnant women and those with poor immune systems. Symptoms of parovovirus B19 infection include fever, chills, runny nose, and drowsiness followed about 2 weeks later by a rash and joint pain. Symptoms of hepatitis A may include several days to weeks of poor appetite, tiredness, and low-grade fever followed by nausea, vomiting, and pain in the belly. Dark-colored urine and yellowing of the skin or whites of the eyes may also occur. Contact your doctor if you develop any of these symptoms after treatment with factor IX complex.

If you experience any of the following serious side effects, contact your healthcare provider immediately or seek emergency medical attention:

  • an allergic reaction (shortness of breath; wheezing; tightness of the chest; closing of the throat; hives; swelling of the lips, face, or tongue; hives or rash; dizziness or fainting); or
  • fever;
  • nausea or vomiting;
  • increased heart rate;
  • decreased blood pressure (may result in dizziness or fainting);
  • difficulty breathing, chest pain, or cough; or
  • pain, redness, or swelling at the injection site.

Other, less serious side effects may be more likely to occur. Continue to use factor IX complex and talk to your doctor if you experience

  • headache; or
  • flushing.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
