Krystexxa (Pegloticase) (Pegloticase) — Uses, Dosage, Side Effects & Safety

Drug class: Urate Oxidase Enzyme (Uricolytic Agent)

Overview

Krystexxa (Pegloticase) is a prescription medication used to treat chronic gout in adults who have not responded to other uric acid-lowering treatments. It is especially helpful for people with severe, treatment-resistant gout, sometimes called refractory gout. Krystexxa works by breaking down uric acid in the body, converting it into a harmless substance called allantoin, which is then easily eliminated by the kidneys. This helps reduce uric acid levels and can dissolve gout crystals, relieving pain and swelling in joints. Key points: Krystexxa is given by intravenous infusion, usually every two weeks, in a healthcare setting. It is not used for mild gout or for people who can control their uric acid with other medications. Serious allergic reactions can occur, so close monitoring is required during and after each infusion.
