Benzydamine liquid is used as a mouth rinse or gargle to soothe sore areas in the mouth or throat. It should not be swallowed.
For treatment associated with radiation therapy, benzydamine should be started the day before the start of radiation therapy and continued daily during the treatment period, as well as after the treatments have stopped, until there is improvement in the discomfort. When used as a mouth rinse, the usual adult dose is not less than 15 mL (1 tablespoonful) used to rinse the mouth, 3 or 4 times a day, depending on the severity of the condition being treated. Keep the liquid in contact with the affected area for at least 30 seconds and then spit it out of the mouth.
For sore throats, benzydamine should be gargled, 15 mL (1 tablespoonful) every 1½ to 3 hours.
If the solution causes a burning sensation or irritation it may be diluted 1:1 with lukewarm water.
