Side Effects

6 ADVERSE REACTIONS The most common adverse reaction (reported in ≥20% of patients) is injection site reactions.

The safety of OXLUMO has been evaluated in a placebo-controlled trial and two single-arm clinical trials. Across these trials, 98 patients with PH1 have been treated with OXLUMO, including 71 pediatric patients and 15 patients on hemodialysis.
