Prolongation of QTc interval
Pyloric stenosis (infantile hypertrophic pyloric stenosis, IHPS) has been reported with erythromycin and azithromycin in infants less than 6 weeks
While less risk of interaction compared to other macrolides, several potential CYP450 interactions may occur; consult a pharmacist for for more details.
Avoid concurrent use with other drugs that prolong QTc
Monitor for signs or symptoms of infantile hypertrophic pyloric stenosis (IHPS) if infant under 6 weeks of life.
Azithromycin is still the drug of choice for treatment or prophylaxis of pertussis as the risk of developing severe pertussis outweighs the potential risk of IHPS.
