MuGard® Oral Mucoadhesive is a mucoadhesive product. When swirled gently around the mouth, the mucoadhesive formulation results in the formation of a protective coating over the oral mucosa. The device is supplied in plastic bottles and is designed for the management of oral wounds such as mucositis, stomatitis, aphthous ulcers and traumatic ulcers.


Purified water, glycerin, benzyl alcohol, sodium saccharin, Carbomer Homopolymer A, potassium hydroxide, citric acid, polysorbate 60 and phosphoric acid.


Each plastic bottle contains 8 fluid ounces of oral mucoadhesive.

Indications & Dosage


MuGard is indicated for the management of oral mucositis/stomatitis (that may be caused by radiotherapy and/or chemotherapy) and all types of oral wounds (mouth sores and injuries), including aphthous ulcers/canker sores and traumatic ulcers, such as those caused by oral surgery or ill-fitting dentures or braces.


Directions For Use

Gently pour 5 mL of MuGard into the mouth and rinse the entire oral cavity for a minute or longer if possible. If the action of rinsing is inconvenient or too painful, MuGard can be spread throughout the mouth by a gentle rotating action of the head. Ensure that all parts of the oral cavity have been coated with the rinse. If necessary, up to 10 mL may be used to fully coat the inside of the mouth. After rinsing, excess rinse may be expelled or swallowed.

For the management of oral mucositis/stomatitis, it is recommended that MuGard is used 4-6 times a day. It is recommended that patients purchase MuGard prior to the commencement of cancer therapy.

For other ulcerative conditions of the oral cavity, MuGard should be used 4-6 times a day or as needed.
