Azithromycin raises risk of cardiac death

A common antibiotic previously thought to be non-cardiotoxic has been found to increase the risk of cardiovascular death.

A large US study found a small but significant rise in cardiovascular mortality during five days of azithromycin therapy, with patients 2.9 times more likely to die from cardiovascular causes than those not taking antibiotics.

Relative to amoxicillin, azithromycin increased the risk of cardiovascular death 2.5-fold, and was responsible for 47 additional cardiovascular deaths per one
