What should I watch for?
Tell your doctor or healthcare professional if your symptoms do not start to get better or if they get worse.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.
