Pharmacology/Pharmacokinetics/Stability â Following oral administration, azithromycin reaches peak bloodstream concentrations in 2.2 to 3.2 hours. Within 48 hours, most patients with pneumonias will be afebrile. The liver is responsible for most metabolism of azithromycin. Antibiotics fall into three major classes according to their mechanism of action: cell walls, protein synthesis, or nucleic acid synthesis. Cell wall agents attack bacterial cell walls.
Recently I was very sick and was given azithromycin for five days. While I was on it, I had terrible stomach pain and diarrhea. Now, it is about three to four days after, and I've been noticing blood in my urine. I also have stomach pain every so often, lower back pain, and feel very tired during the day. This all started about three days into taking the medicine.
