Is clindamycin phosphate lotion safe for me to use when i have crohns? i read online its not safe, even topical use. this medicine is for random acne that appeared. 29yr male?

No real evidence that it’s bad. The systemic form (IV or oral) often causes stomach upset and, uncommonly, may cause a diarrheal condition termed C. Difficile colitis. However, no evidence that either systemic form exacerbates Crohn’s. The warning about the topical form is simply extrapolated from the IV/oral forms without any direct proof. Of course, absence of proof is not proof of absence!
