Hi I was just wondering if any of you have taken the antibiotic CLINDAMYCIN and if you have had any neggative effects that may concern Pots? I went to the ER last night because I had noticed a bug bite I had got 4 days earlier had gotten a3 inch red, raised ring around it, and I was having heart rates in the 130's-140's while laying down. Usually rates are in the 80's-90's laying, occasionially up to 105 or so. I was not sure if the heart rate was up because of the bite or maybe the anxiety I was having about the bite. Anyway of course the ER Dr. new nothing about pots, she said I have a fairly serious bacterial infection of the skin called cellulitis, and gave me a prescription for clindamycin after reading the possible side effects (pseudomembranous colitis which can be serious to deadly form of diarrea) that can occur even a couple months after discontinuing the med. I am not sure that I want to take it. I know many of us already have digestive issues, mine are not to bad but dont want to cause a new problem. Also is the issue of dehydration which I do battle because of frequent urination. Doesnt diarrhea make dehydration worse? I did read that many antibiotics can cause colitis, but that it is much more associated with the above antibiotic. I get so freaked out whenever I read the information/side effects sheet for any new med. I'm going call my regular Dr. in the morning but she doesnt know much about pots, although she has read all the info I have given her. Hopefully I will be able to get a prescription for something I have taken before, that will help the condition Im dealing with now. If any of you have taken this med or know anything about it I would really appreciate any info or comments you may have. Thanks
