I had CDIFF before in the hospital can I get it again from takin penicillin vk for a tooth infection. I have had diarrhea for days but no vomiting?

Dangerous C. diff: Absolutely -if you've had C. diff once, you are at increased risk to get it again. ANY antibiotic can trigger it off-so if you're on Penicillin now with a lot of diarrhea, you need to get this checked. Antibiotics have some benefit but also RISK -and in your case, I'm worried about a relapse of C. diff. This is a very nasty disease. Different antibiotics have different rates of causing C. diff BTW ...Read more

Read that anti-depressants can cause hems because of side effects like diarrhea. Is this true? How long would diarrhea epis have to be to cause them?

It never ceases to amaze me how many people blame their meds for every ailment. ...Read more
