FDA warns against long-term azithromycin use for some
(HealthDay)—The U.S. Food and Drug Administration is warning patients with cancers of the blood or lymph nodes who undergo a donor stem cell transplant not to take azithromycin, as long-term use of the antibiotic has been associated with increased risk of cancer relapse.
