Bromhexine is used to treat respiratory disorders that are caused by excessive or overly sticky mucus. Bromhexine, which is sold under the brand names Bisolvon or Barkacin, acts as a mucolytic agent that increases the water content of mucus, making the mucus thinner and less sticky. This thinner phlegm is more easily expelled out of the lungs. Bromhexine can be administered by itself, or it is sometimes included in cough syrups. The side effects caused by bromhexine are generally mild, although rare cases of severe allergic reactions have been reported.
