I recently visited the dermatologist and she prescribed me Greenstone brand Clindamycin phosphate topical lotion 1%. She also prescribed me some sort of tretinoin but my insurance apparently said there was an age limit of 25 on it(?) and didn't ok it, so I am waiting for the doctor's office to authorize it. Does anyone have experience with this stuff? I am worried because the instructions say that it can cause colitis, and I am a special case because I have had much of my colon and large intestine removed, as well as some of my small intestine. (Warning, bowel talk ensues) Because of this I have diarrhea all the time. I take Metamucil to remedy this and it helps greatly. However, it says diarrhea is a side effect and I just want to make sure I'm not hurting myself when I think something normal is happening to me. I am going to call the doctor's office on Monday to ask them about this. I just figured maybe you fine folks might be able to provide me with some insight. I think, I think that I have noticed a correlation between my diarrhea and acne although I am not entirely sure. I don't always keep up with the Metamucil so it's tough to tell, but I am nearly certain that when my poop isn't solid then my acne flares up. I am going to be more consistent with my Metamucil and see what happens with my face. I am just so sick of having acne and I've tried everything. My face is constantly oily. The last time I went to the dermatologist we discussed a second round of Accutane but I don't really want to do it. I'm just trying to eat healthier and using topical stuff when I can. I really don't know what to do.
