Summary
Progestogens may impair glucose tolerance and so partly offset the effect of inhaled insulin. Some patients may need higher insulin doses.
What this interaction means in plain words
Insulin inhaled and Norethisterone 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
Progestogen-induced insulin resistance antagonises the glucose-lowering effect of insulin.
What to do
Check blood glucose more frequently when beginning or stopping norethisterone and titrate the insulin dose as needed.
