About: Mucosal Coating Rinse (MuGard®)

This medication works by adhering (sticking) to the mucosal surface of the mouth. By adhering to the outer layer of the inside of the mouth it creates a protective layer that covers any ulcers. It is used in the treatment of mucositis, stomatitis, and ulcers. 

How To Use Mucosal Coating Rinse

Use the measuring device provided by your pharmacist with the medication to administer the correct dose. Put the medication into your mouth and gently rinse your entire mouth for at least one minute. If you have trouble swishing it around your mouth you can gently rotate your head so that the liquid covers all parts of the inside of your mouth. Once the inside of your entire mouth has been covered you can either spit out the remaining liquid or you can swallow it. Your provider will tell you how often you can use this medication. 

It is important to maintain proper dental hygiene. You should not eat or drink for at least one hour after using this medication. Always check the expiration date prior to use. Also, you should not add any liquids to the medication prior to using it. 

In rare cases allergic reactions have been reported. If you have a new rash or hives, trouble breathing, swallowing or talking, or have new swelling, stop taking this medication and notify your provider right away.
