Azithromycin is a member of the group of drugs known as microcline antibiotics. It eliminates bacteria or stops their growth to function. It works by preventing the synthesis of essential proteins required by bacteria to carry out vital functions. Thus, it stops the bacteria from growing and prevents the infection from spreading. For the treatment of patients with enteric fever, azithromycin pills are a highly effective drug. Azithromycin comes as a tablet, an extended-release suspension, and in liquid to take by mouth. Azithromycin may cause side effects like nausea, diarrhea, vomiting, stomach pain, and headache.
