Summary
Estrogen-containing contraceptives can modestly reduce glucose tolerance and insulin sensitivity. In patients with diabetes this may lead to higher blood glucose and a need for more insulin.
What this interaction means in plain words
Ethinylestradiol and Insulin lispro can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Estrogen-progestin products can induce insulin resistance, which opposes the glucose-lowering effect of insulin.
What to do
Monitor blood glucose when starting, changing or stopping the contraceptive and adjust the insulin dose as needed. Low-dose formulations are preferred in diabetes.
What to ask your pharmacist
