Adverse reactions reported in more than 5% of adults with PNH treated with FABHALTA during the initial study period (Weeks 0 to 24)

Tell your doctor about any side effect that bothers you or that does not go away. These are not all the possible side effects of FABHALTA.

• Serious adverse reactions (COVID-19 and bacterial pneumonia) were reported in two people (5%) with PNH receiving FABHALTA

• FABHALTA may increase your cholesterol and triglycerides and your health care provider will do blood tests to check these periodically during treatment

• Nausea and bacterial infection were each reported in two people (5%) and dizziness and hives were each reported in one person (3%)

• One serious adverse reaction (COVID-19) was reported in 2.5% (1 of 40) of people on FABHALTA

• Adverse reactions that occurred in more than 5% of people were viral infection (12.5%), nasal congestion, runny nose, cough, sneezing, and sore throat (10%), and diarrhea (7.5%)

Throughout the 48 weeks of this study, no person discontinued FABHALTA due to an adverse reaction.
