Clindamycin
"Would never recommend this antibiotic! I was prescribed 7 days 3 times a day today take this med so I did, I have a very bad stomach to start with. I was able to do my first 7 days without a problem, then after my seven days I started to have really bad diarrhea and I rarely have this. It has lasted now for like two weeks. Now I had to restart another dosage of clindamycin for another 7 days but I saw that they were not the same colour as the other ones I had taken I don't know why but anyways I started them yesterday and I've never felt sicker! My stomach was very upset, diarrhea, nausea, chills, fever, dizziness and my throat is hurting. I not one to complain usually but after this I immediately stopped the medication! Never again"
