Tophi (TOE-f-EYE) are telltale signs your gout is out of control. When uric acid levels remain high and gout is out of control, deposits of uric acid crystals can develop into hard visible lumps that damage your joints and bones. Tophi can be microscopic or large and, though rare, may need to be surgically removed. It’s also possible for tophi to erupt on their own.

KRYSTEXXA CAN MAKE A DRAMATIC DIFFERENCE

In clinical trials, nearly half of KRYSTEXXA patients had at least one tophus completely go away after 6 months, and they didn’t experience any new tophi growth.
