Long-term use of this product can lead to kidney damage, uremia, bladder cancer, cause dependence, etc., so this product can not be used for a long time. The aminopyrine in Phenazopyridine can interact with food under the action of gastric acid to form nitrite-based compounds, which are potentially carcinogenic.
