A primary care NP is preparing to prescribe a macrolide antibiotic for a patient who has a history of a prolonged QT interval on electrocardiogram. Which macrolide antibiotic should the NP prescribe?
a. Erythromycin
b. Azithromycin
c. Clarithromycin
d. Telithromycin
B
Azithromycin does not cause a prolonged QT interval , unlike the other macrolides, so it would be safe for this patient. Visual disturbances have been found to occur with the use of telithromycin. Erythromycin has a wider range of adverse effects and can cause cardiac effects in patients who have a prolonged QT interval. The Ilosone, E-Mycin, and Erythrocin are all erythromycins.
