Dequadin (Dequalinium) is an over the counter lozenge medication used to treat common infections of the mouth including mouth ulcers, oral thrush, pharyngitis, and tonsillitis. Dequadin contains dequalinium chloride, which belongs to the class of organic compounds called aminoquinolines, and has both antiseptic and pain-relieving properties. Dequadin kills a wide range of bacteria, yeasts, and fungi that are associated with various mild infections of the mouth and throat. It does this by increasing cell permeability, stopping the microbe’s enzyme activity. Once microbes lose their enzymatic abilities, they quickly lose their ability to survive, as enzyme activity can affect the microbe’s osmotic system, cell metabolism, energy production, and protein synthesis, which are all necessary for the survival of the infection. Sucking a lozenge allows this medication to work directly in the area of the infection. It also lubricates and soothes the painful area, helping to relieve soreness and discomfort. If your symptoms do not improve after three days of using Dequadin or if they worsen, contact your doctor.
