ycaemia less frequently (Jovanovic
and Pettitt, 2011). However, there continues to be
concerns regarding teratogenicity with basal insulin
analogues and, in particular, insulin glargine, which
has demonstrated increased affinity for insulin-like
growth factor-1 receptor binding. In addition, following
a meta analysis by Fieg et al (2011), no evidence has
been documented for increased adverse fetal outcomes
with the use of insulin glargine in pregnancy compared
with the use of NPH insulin, and following a large
randomised, controlled trial in women with type 1
diabetes, a label change was assigned to Novo Nordisk’s
insulin detemir (ribosomal DNA origin) injection to a
pregnancy category B designation, indicating that the
drug does not increase the risk of harm to the fetus
