HAEGARDA safety and side effects

In a 32-week clinical trial, side effects for people taking HAEGARDA were usually mild

In clinical studies, the most common side effects reported with HAEGARDA were injection-site reactions (pain, redness, swelling), hypersensitivity (itching and rash), dizziness, and nasal symptoms, including stuffy or runny nose and sneezing. These are not the only side effects possible with HAEGARDA.


We understand that you want the medications you take to meet the highest safety and quality standards. That’s why HAEGARDA goes through an advanced screening and purification process to reduce the risk of transmitting infection.

Our process includes:

  • Carefully selecting and screening US plasma donors
  • Thorough testing for viruses
  • Pasteurization (heat treatment for 10 hours)
  • Virus nanofiltration

We are committed to producing high-quality, safe and effective medicines. To us, that means that each step of the manufacturing process must meet or exceed the most stringent international standards for product safety in accordance with regulatory agencies worldwide.*

*The risk of transmission of infectious agents cannot be completely eliminated.
