It worked for me when I used it with tretinoin (generic retin-a). I also tried clindamycin which seems to be the main antibiotic in the stuff you have tried and it did NOTHING for me. I'm guessing that maybe erythromycin might just help you a lot like it helped me since it seems as if the clindamycin variety isn't working as well as you might want it to work. Good luck either way =)
