alli will not interact with Yaz or penicillin.
alli does not impact the efficacy of you birth control medicine. A clinical trial using orlistat in 20 normal body weight women taking birth control pills for 23 days found that orlistat had no effect on the ovulation suppression action of the birth control. Note that Yaz has a potassium sparing effect to it and weight loss, especially with an increase of diuresis and sweating (hot weather) your potassium levels may shift, this may be of concern and its best to check with your physician , espeicially if Yaz is prescribed for you other than for birth control because of it potassium sparing action.
Hope this helps.
