question: Hello! I am a dentist.   My patient was on Amoxicillin  after I did open flap surgery to control the infection on her lower jaw.  I switched it to Clindamycin 300mg  2 stat 1PO q6h three days later because her swelling became worse.  Today is the 4th day since she took the Clindamycin.  She said the facial swelling went down a lot but  now  she is concerned  that her stomach is hurting today.   I like to know whether I need to tell her to stop taking the Clindamycin immediately?   I hope I can put her on the medication for few more days to control the infection because I do not want the facial swelling to return.  What is the minimum number of days to control infection?
