Frequently asked questions about AlphaNine SD (factor IX)

What is hemophilia B?
Hemophilia B is a rare blood condition that makes it difficult for your blood to clot. This condition is typically genetic, meaning it's passed down from parent to child. But in some cases, people with this condition have no prior family history. If you have hemophilia B, your body is missing factor IX, which is one of the clotting factors your body needs to make clots. Without this clotting factor, you're at a higher risk for bleeds and can experience symptoms ranging from minor bruising and bleeding to more serious bleeding in the muscles and joints, depending on how severe your condition is.
How long do I need to be treated with AlphaNine SD (factor IX)?
AlphaNine SD (factor IX) is typically only used on an "as-needed" basis, meaning you'll only receive treatment when you experience a bleed or go through surgery. Your length of treatment typically ranges from 1 to 10 days, depending on how serious your condition is and how well your body responds to this medication. Some people with hemophilia B need to have regular factor IX replacements to prevent future bleeds (prophylaxis treatment), but AlphaNine SD (factor IX) isn't approved for prophylaxis. Talk with your provider if you've any questions about how long you need AlphaNine SD (factor IX) treatment.
Can I give myself AlphaNine SD (factor IX) infusions at home?
Ask your provider if it's okay for you to give yourself AlphaNine SD (factor IX) infusions at home. Because this product is typically used during an active bleed or during surgery, you'll probably receive AlphaNine SD (factor IX) under the care of a healthcare provider. But sometimes, it might be possible for you to receive AlphaNine SD (factor IX) at home. Ask your provider if or when home infusions might be appropriate for you.
What's the difference between AlphaNine SD (factor IX) and Benefix (factor IX)?
Both AlphaNine SD (factor IX) and Benefix (factor IX) are clotting factor replacements used to treat hemophilia B. The main difference between them is how they're made. AlphaNine SD (factor IX) is made from donated human plasma, while Benefix (factor IX) is made in a lab using recombinant technology. Because AlphaNine SD (factor IX) is made from donated human plasma, there's a very small chance that it can contain viruses or other infectious material from human blood (though the manufacturer takes many steps to make sure it's safe). Recombinant products, such as Benefix (factor IX), are generally considered safer because they're made in the lab and don't carry the same risk of potential infections from receiving human-derived products. Currently, providers typically prefer recombinant factor IX products over ones made from human plasma.
Can I take AlphaNine SD (factor IX) if I'm pregnant?
AlphaNine SD (factor IX) hasn't been well studied in human pregnancy, so it's not known whether this medication is safe in pregnant females.AlphaNine SD (factor IX) should only be used in pregnancy only if it's clearly needed. If you're pregnant, or thinking of becoming pregnant, talk with your provider about the risks and benefits of using AlphaNine SD (factor IX) before starting this medication.

What are the risks and warnings for AlphaNine SD (factor IX)?

AlphaNine SD (factor IX) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

risk-warning

Serious allergic reactions

Serious allergic reactions to AlphaNine SD (factor IX) are possible, including life-threatening reactions like anaphylaxis (closing of the throat). This can happen anytime during or after an infusion. If you've never been treated with AlphaNine SD (factor IX) before, your risk might be higher around days 10 to 12 of treatment. If you notice dizziness, a choking sensation, sweating, dizziness, nausea, swelling around your eyes, swelling of the lips or tongue, or difficulty breathing after using AlphaNine SD (factor IX), stop using it and get medical help right away.

risk-warning

Risk of blood clots

  • Risk factors: History of blood clot problems | High blood pressure | High cholesterol | High blood sugar | Obesity | Cancer | Surgery | Taking estrogen-containing birth control | Not moving much or exercising | Smoking tobacco | Pregnancy | Liver problems

    AlphaNine SD (factor IX) can raise your risk of getting blood clots in various parts of your body as well as also cause a condition called disseminated intravascular coagulation (DIC), which is when your body forms abnormal clots throughout your body. Symptoms of a blood clot might be different depending on the location of the clot, but they can include chest pain, difficulty breathing, swelling or warmth in the legs, and weakness of the face, legs, or arms. Call 911 if you have any of the symptoms above because this is a medical emergency.

    risk-warning

    Infections

    • Risk factors: Medical conditions that weaken your immune system | Taking medications that can weaken your immune system

      Because AlphaNine SD (factor IX) is made from human blood products, there's a risk that it might contain viruses that can make you sick. But your risk of infection is pretty low because donors of these blood products are screened. Also, there are high manufacturing standards put into place to make sure the viruses are killed or removed. To prevent serious infections in the rare case that your medication is affected, let your provider know right away if you start to feel sick or have symptoms such as feeling confused and anxious, or having trouble maintaining your balance. Make sure you're up to date on your vaccines before starting AlphaNine SD (factor IX) to prevent infections.
