I am starting Macrobid today to clear up a bladder infection. I only have 1 day left of my birth control pack. I wait a week then start a new package. I am wondering if their will be any intereference? Thanks!
The pharmacist said something about it being an anti-septic and not working the same as an antibiotic. Therefore, she said its not like penicillen, its just there to clear the bacteria. Maybe I misunderstood her though?

Yes, most antibiotics interfere with birth control pills. They activate enzymes that metabolize the hormones in birth control pills. Essentially, the hormones are broken down so fast that they don’t work on you.
Whether or not it will inactivate the first pills of your next pack depends on how long you will be taking the macrobid. By no means do you want to stop taking the macrobid early, you need to finish all those pills. But you should consider using back up birth control (such as condoms) until you are finished with the macrobid.
Hope this helps!
Thumbs up Josie. But backup birth control until the antibiotics are done PLUS one week to 10 days.
