I am allergic to penicillin, codine, sulpha, erthoymicen and now I am allergic to clindamycin and hydrocodonacetaminophen. I just learn about the clindamycin because it gave me rash all over my face. I quit taking them and it is gone but marks is still invisible. Now dentist is unable to do work on my teeth till I get something different antibiotic before any work on my teeth. Anyone can help or suggestion who is going through the same situation?
