If i have a mirana and my diet pills say may interfere with birth control and i take them every day, do i use condoms every time?

Safely yes: It is uncertain why a iud works at all. That being the case it may be easyto mess up birth control with your diet. Play it safe and use condoms unless you do not mind another baby.

No need: To use a condom with an iud. This mechanism works even without the hormones, which work locally in the uterus and are not subject to increased metabolism, good luck.
