I'm not currently on Clindamycin but i figured id reply for you guys just because My derm prescribed Clindamycin Phosphate Gel like two+ years ago and i didnt even use it for like 2 weeks because i had never heard anything about anything called clindamycin and figured it was a waste, then when i finally used it it stopped my breakouts immediately. I didnt have severe acne, just the pimple or two on my forhead every day and acne on my back, and though i didnt use it for my back, it kept my face clear and in check for i'd say almost a year. Your body builds up resistance to it after a while and the anti-bacterial part of it doesnt work anymore. Since i had never heard of that before and had never ever used it i think thats why it worked so well, it killed the bacteria that caused my acne like crazy. I'd definitely wait a while to see if it worked and give it a try. I went to the derm for probably 4 years and out of alllll the stuff i have tried, Clindamycin Phosphate was my favorite, it never dried me out and just improved the overall look of my skin. But i should probably mention that ive heard some people dont have as good of results when they have it in lotion or foam form, i had the gel, and when i used the foam and lotion later on, it didnt work as well, but that might be because i had it before, but since people have also said that, maybe if these dont work you should try it in a different form. Hope i helped at all! Sorry about the long post, i always try to inform about things that actually have worked for me. Good Luck!
