Duzallo Overview

Reviewed: November 8, 2017
Updated: 

Duzallo is a prescription medication used to treat high blood uric acid levels. It is a single product containing 2 medications: allopurinol and lesinurad. Lesinurad belongs to a group of drugs called urate transporter inhibitors. These help by increasing excretion of uric acid in the kidney. Allopurinol belongs to a group of drugs called xanthine oxidase inhibitors. These work by decreasing how much uric acid is made in the body.

This medication comes in tablet form and is taken once a day in the morning with food and water.

Common side effects of Duzallo include skin rash, headache, and flu-like symptoms. Duzallo can also cause drowsiness. Do not drive or operate heavy machinery until you know how Duzallo affects you.
