Summary
Estrogen-containing contraceptives can impair glucose tolerance and reduce insulin sensitivity. Insulin requirements may therefore increase in patients with diabetes.
What this interaction means in plain words
Ethinylestradiol and Insulin aspart 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
Estrogens and progestins can reduce peripheral insulin sensitivity, antagonizing the glucose-lowering effect of insulin.
What to do
Monitor glycemic control when starting or stopping ethinylestradiol and adjust the insulin dose as needed. Consider the lowest effective estrogen dose and assess vascular risk in diabetes.
