Clarithromycin (Biaxin) is in a class of medications called macrolide antibiotics, and is derived from erythromycin. It works as an antibiotic by stopping the growth of bacteria, and was approved by the U.S. FDA in 1991 for treating certain infections. It has been shown in a small, randomized trial to improve daytime sleepiness and quality of life more than a placebo, in those people with primary hypersomnias related to excess activity of the GABA system.
