Dequalinium is a topical antiseptic and antimicrobial agent used to treat infections of the mouth, throat, and vaginal area. It works by disrupting the cell membranes of bacteria and fungi, leading to their destruction. Dequalinium is commonly available in the form of lozenges for oral and throat infections, and as vaginal tablets for the treatment of conditions such as bacterial vaginosis. It is used locally and is generally well tolerated when used as directed.
