Summary
Estrogen therapy can modestly impair glucose tolerance and insulin sensitivity in some patients, which may slightly reduce the glucose-lowering effect of metformin. The effect is usually small and variable, particularly with transdermal or low-dose products.
What this interaction means in plain words
Conjugated estrogens and Saxagliptin-metformin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Estrogens may alter insulin sensitivity and hepatic glucose metabolism, opposing the glucose-lowering effect of antidiabetic drugs (pharmacodynamic antagonism).
What to do
Check blood glucose and HbA1c after starting, stopping or changing the estrogen dose in a patient with diabetes. Adjust antidiabetic therapy only if glycemic control worsens.
