Ptyalism, or Excessive Salivation during pregnancy

This uncommon complaint caused by excessive secretion of the salivary glands is very annoying and difficult to cure. The secretion of saliva virtually floods the mouth and is so profuse that the patient cannot manage to swallow all of it, so must continually expectorate. Ptyalism is often accompanied by a foul taste which some patients find relieved by sucking peppermints or chewing gum. Small daily doses of a mild sedative such as phenobarbital may diminish the ptyalism. The condition frequently persists throughout pregnancy but in my experience tends to diminish in its latter half and always disappears promptly with delivery.
