Duo Fresh Mouthwash combines two medicines containing Benzydamine and Chlorhexidine gluconate. Benzydamine, Chlorhexidine gluconate, is a non-steroidal anti-inflammatory drug (NSAID). It treats pain and inflammation, including swelling, redness, and a feeling of heat in the mouth or throat. It works by inhibiting the formation of prostaglandins (increased blood flow to the injured area causes discomfort and swelling). Chlorhexidine gluconate is an antiseptic that binds to the surface of inner cheeks, gums, or teeth and reduces the accumulation of microbes on the oral surface. Talk to your physician if you have a history of asthma or allergies. Don’t use Duo Fresh Mouthwash if you are allergic to Benzydamine, Chlorhexidine gluconate, or any other ingredients of this medicine. Don’t splash the Duo Fresh Mouthwash on your eyes while using it. Inform your doctor if you are allergic to Acetylsalicylic acid or other non-steroidal anti-inflammatory (NSAID) drugs. Before taking Duo Fresh Mouthwash, notify your doctor if you are pregnant or planning to get pregnant or breastfeeding. Consult whether this mouthwash is safe to use or not in such conditions. Report to your physician immediately if you experience any symptoms, such as an allergic reaction or tightening of the throat or chest, after using the Duo Fresh Mouthwash. Do not use it more than 4 times at the same time.
