StrataChlor-4% is a full-strength medicated shampoo with 4% Chlorhexidine Gluconate, combining penetrating agents and emollients for mild to severe dermatologic conditions where a full-strength antimicrobial, cleansing, and deodorizing shampoo may be of benefit. Unlike the StrataChlor-CK line, which pairs chlorhexidine with an antifungal, StrataChlor-4% is chlorhexidine only at double the standard 2% concentration, making it a good option when a stronger antibacterial effect is needed without an antifungal component. It is a pleasantly scented shampoo with antiseptic antibacterial activity, designed for dogs, cats, and horses. Use as directed by your veterinarian.
