Zithromax is a macrolide antibiotic, used to treat certain types of infections caused by bacteria. It is most commonly used to treat ear infections, throat infections, lung infections, and certain STD’s. It contains the active ingredient azithromycin and is for use through oral administration. It works by widely distributing itself throughout the body once absorbed. When culture and susceptibility information is available it should be considered in selecting antibacterial therapy.


Common side effects of Zithromax are mild diarrhea, mild stomach pain or upset, dizziness, or vaginal itching or discharge. There may also be various gastrointestinal, cardiovascular, hepatic and nervous system side effects.


Zithromax’s role as a macrolide antibiotic make its potential for liver damage high. Reports of liver damage associated with the drug were first received in 1996, and the public was warned it 2000. In 2001 the FDA required Zithromax to state on its label a warning that abnormal liver function, jaundice, necrosis, hepatic failure and death had been reported in patients taking the drug. It was also announced in 2006 that Zithromax might increase the risk of being re-infected with a potentially blinding eye disease that it is intended to treat, called Trachoma. These effects, along with others, have led to a number of Zithromax lawsuits.
