Summary
Exenatide slows gastric emptying and could delay absorption of oral contraceptives, though a clinically important loss of efficacy has not been established. Ethinylestradiol can also modestly impair glucose tolerance and weaken glycemic control.
What this interaction means in plain words
Ethinylestradiol and Exenatide 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
Delayed gastric emptying slows oral drug absorption, and estrogen reduces insulin sensitivity (pharmacodynamic antagonism).
What to do
Advise taking oral contraceptives at least 1 hour before exenatide where timing matters, and monitor blood glucose after starting or changing the contraceptive.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
