If you were my patient, I would advise you that Adios is a natural supplement, and as such, is not regulated by the FDA and is not well studied in
terms of actions and interactions. SO, I can not find scientific evidence that it interferes with the action of birth control pills, nor do the active ingredients seem like they would reduce the effectiveness of the pills.
Certainly pregnancy would not help with weight loss, so if you are going to use Adios, you should probably continue your pills.
