Long-acting insulin analogue
Insulin Glargine after 60: doses and safety in older adults
Older adults metabolise medications differently, accumulate more comorbidities and take more concomitant drugs than younger users — all of which affect how Insulin Glargine (Insulin Glargine) should be prescribed and used after age 60. The standard 100 IU/mL starting strengths are usually adjusted, and the safety priorities shift.
Dose adjustments after 60
According to the prescribing information, most adults over 65 start Insulin Glargine at the lowest available strength of 100 IU/mL and titrate up only with clear benefit and good tolerance. Reduced renal and hepatic function in older age slows clearance of Insulin Glargine and prolongs effects. Caution is greater in the very old (>75).
Specific risks to consider
Falls, postural hypotension, confusion and interaction with cardiovascular medications are the main amplified risks for Insulin Glargine after 60. Insulin glargine binds the insulin receptor with similar affinity to human insulin, activating intracellular signalling that increases glucose uptake in muscle and adipose tissue, suppresses hepatic g… A standing blood pressure check after the first weeks of therapy is a simple, useful precaution.
