Pre-med IS indicated - many of the OSCE quizlets say no.... Pre-med options for pregnant woman w/hx of infective endocarditis and penicillin allergy - amoxicillin - cephalexin - clarithromycin - ciprofloxacin Correct Answer *clarithromycin* I may not be correct; the correct option may be cephalexin. however, I chose clarithromycin due to penicillin allergy, cross reaction with cephalosporin, and since clindamycin/erythromycin/azithromycin were not options.
