My surgeon feels that I am a very low risk for problems and has not recommended any penicillin. I am taking no meds at all. I do take vitamin C, but that is it. He simply said when I go to the dentist, that i need a course of penicillin. I want to build a healthy immune system from the ground up. I am getting meningitis vaccine and hib vaccine tomorrow. I got the pneumonia vaccine prior to surgery.
