Oromist spray 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 Oromist spray if you are allergic to Benzydamine, Chlorhexidine gluconate, or any other ingredients of this medicine. Don’t splash the spray in 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 Oromist spray, notify your doctor if you are pregnant or planning to get pregnant or breasting. Consult whether this spray 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 spray. Do not use the spray more than four times at the same time.
