Torsade de pointe due to QT prolongation following erythromycin administration in a preterm infant.

Erythromycin should be administered in neonates only if no other choice is available, as although generally well tolerated, its administration can be associated with QTc interval prolongation. When no other option is available, paediatricians should be aware to perform cardiac monitoring or at least serial ECGs before and during erythromycin administration.
