Duzallo

Generic name: Allopurinol And Lesinurad
Drug class: Antihyperuricemic agents

Usage of Duzallo

Duzallo contains a combination of allopurinol and lesinurad. Allopurinol reduces the production of uric acid in your body. Uric acid buildup can lead to gout.

Lesinurad helps the kidneys remove uric acid from the body.

Duzallo is used to reduce blood levels of uric acid in adults with gout.

This medicine is usually given when taking allopurinol alone has not been effective.
