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.

HAE can be managed during pregnancy. Talk with your doctor about C1-INH when family planning.

  • There are no prospective clinical data from HAEGARDA use in pregnant women
  • A review of past pregnancies showed pregnant women with type 1 HAE received C1-INH doses of 500 or 1000 IU per I.V. administration for the treatment of acute attacks before, during, and/or after pregnancy (22 patients, 35 pregnancies)
  • Additionally, in an observational registry, data was collected on 11 pregnancies in 10 patients who received up to 3000 IU C1-INH (I.V. administration) doses to treat or prevent HAE attacks
  • No adverse events were associated with C1-INH treatment before, during, or after pregnancy

Before taking any HAE therapies, consult with your doctor if you are pregnant or considering becoming pregnant
