It also is effective against several sexually transmitted infectious diseases such as nongonococcal urethritis and cervicitis. ...
Rare side effects include abnormal liver tests, allergic reactions, and nervousness. Azithromycin is generally well tolerated. The most common side effects are diarrhea or loose stools, nausea, abdominal pain, and vomiting which may occur in fewer than one in twenty persons who receive azithromycin. Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection (oral or vaginal fungal infection). ...
