Hear from real patients taking ALPROLIX

Meet Casey, a 36-year-old man with severe hemophilia B.

The flexibility of ALPROLIX means Casey could find a dosing interval that worked for him.

“After starting on an every-10-day dosing schedule, I talked with my doctor and was able to adjust my dosing interval.”

Meet Alex a youth soccer coach with moderate hemophilia B.

Alex was able to extend to 14-day dosing with ALPROLIX.

"After working with my doctor and starting on an every-10-day dosing regimen, I was able to extend my dose and infuse beyond every 14 days."

Meet Brian a father and hiker with severe hemophilia B.

Brian transitioned from on demand to prophylaxis with ALPROLIX.

"When I was a teenager, I thought that skipping infusions gave me more control over my hemophilia. Of course, I was hematologist told me about ALPROLIX and a starting dosage of once a week or every 10 days. I was really excited about that."

  • ALPROLIX is contraindicated in patients who have a known history of hypersensitivity reactions, including anaphylaxis, to the product or its excipients.


  • Allergic-type hypersensitivity reactions, including anaphylaxis, are possible with factor replacement therapies, and have been reported with ALPROLIX. Discontinue use of ALPROLIX if hypersensitivity symptoms occur, and initiate appropriate treatment.
  • Formation of neutralizing antibodies (inhibitors) to Factor IX has been reported following administration of ALPROLIX. Patients using ALPROLIX should be monitored for the development of Factor IX inhibitors. Clotting assays (e.g., one-stage) may be used to confirm that adequate Factor IX levels have been achieved and maintained.
  • The use of Factor IX products has been associated with the development of thromboembolic complications.
  • Nephrotic syndrome has been reported following attempted immune tolerance induction in hemophilia B patients with Factor IX inhibitors and a history of allergic reactions to Factor IX. The safety and efficacy of using ALPROLIX for immune tolerance induction have not been established.


  • The most common adverse reactions (incidence ≥1%) in previously untreated patients were injection site erythema, hypersensitivity, and Factor IX inhibition. The most common adverse reactions (incidence ≥1%) in previously treated patients were headache, oral paresthesia, and obstructive uropathy.
