surgical prophylaxis
"Ask Pharmacist if this antibiotic was strong or had any side effects.  He said that is was not considered a strong antibiotic with any serious side effects.  I rarely take antibiotics, avoiding them like the plague just because of bad side effects,  but when I have to take them I always increase my daily intake of probiotics and yogurt.  None of that helped with this miserable drug. I was fine taking this drug the first 3 days, but then on day four I took a pill with Kefir (like yogurt) and had the most severe chest pain I ever had which lasted for over two hours.  Skipped next two doses for the day. Tried one the next morning- had some discomfort. Next dose, more chest pain as if having a heart attack and still have terrible discomfort."
