I have a root canal that was done in 2004.  I know present with an infection at the bottom of the root canal that needs to be redone.  Im allergic to clindamicin and many other antibiotics.  I have had blood sent to the Mayo Clinic for analysis and it comes back no known antibodies to antibiotics except clindamycin family.  My doctor is suggesting infusion antibiotics but does say they may cause an allergic reaction.  I work and can not take time off for daily infusions, pick line etc.  What would you suggest?
Hi. Thanks for the query. From your blood test it is clear that you are allergic to Clindamycin family which means that you should avoid Vancomycin class of antibiotics. So it is better to go for other groups of antibiotics like Penicillin, Cephalosporins etc. In case of tooth related infections, taking oral antibiotics like generally sufficient, so do not worry about getting infusions done and can take oral antibiotics. So it is better to consult an Endodontist and get evaluated. Proper antibiotics under supervision can help in resolution of infection. Hope this helps. Regards.
