Adverse events

At 30 weeks: serious events 1/32, 1/33, 1/34; adverse-event discontinuations 2/32, 0/33, 0/34. Glucose <54 mg/dL: 5/32, 5/33, 2/34; no severe hypoglycemia.

Monitoring

Glucose checks three times weekly and with symptoms; baseline HbA1c <8% required a 20% basal-insulin reduction when used. Hypoglycemia counts exclude events after new antihyperglycemic therapy.
