Is it possible to damage the urethra if Aldare is used incompetently?

Yes, when using Aldara cream, there may be a reaction within the urethra and problems with urination. In this case, you will need to consult your doctor about how to continue to dose Aldara. According to the information available in the Summary of Product Characteristics, "The application of excessive amounts of Aldara cream or prolonged contact with the skin may cause a strong reaction at the application site. In rare cases, severe local reactions that required treatment were observed in patients who used imiquimod as directed. When such reactions occurred at the mouth of the urethra, some women developed difficulty urinating, sometimes requiring catheterization and treatment of the affected area." https://www.gdziepolek.pl/produkty/3145/aldara-krem/ulotka/95524
