Medication Safety Issues

Sound-alike/look-alike issues:

HumaLOG may be confused with HumaLOG Mix 50/50, Humira, HumuLIN N, HumuLIN R, NovoLOG

Humapen Memoir (used with HumaLOG) may be confused with the Humira Pen

High alert medication:

The Institute for Safe Medication Practices (ISMP) includes this medication among its list of drugs which have a heightened risk of causing significant patient harm when used in error. Due to the number of insulin preparations, it is essential to identify/clarify the type and strength of insulin to be used.

Geriatric Patients: High-Risk Medication:

Beers Criteria: Insulin (short- or rapid-acting insulin products used for sliding scale) is identified in the Beers Criteria as a potentially inappropriate medication to be avoided in patients 65 years and older (independent of diagnosis or condition) due to higher risk of hypoglycemia associated with sliding scale insulin without improvements in hyperglycemia, regardless of care setting. Avoid insulin regimens that only use short- or rapid-acting insulins dosed based on current blood glucose levels in the absence of basal or long-acting insulin; recommendation does not apply to regimens containing basal or long-acting insulin (Beers Criteria [AGS 2019]).

Other safety concerns:

Cross-contamination may occur if insulin pens are shared among multiple patients. Steps should be taken to prohibit sharing of insulin pens.
