I currently want to start a weight loss diet and the tea package that I bought comes with a warning saying: "Yes, the teatox can potentially reduce the effectiveness of birth control if you take your pill within 4-5 hours of the laxative effect." What does this mean? If I take my birth control at 4pm in the afternoon and I drink the laxative tea at 9pm at night and the effects come in the morning does that affect the effectiveness of my birth control pill? Please help! I don't want to start this tea regimen not knowing the risk it can have in the effectiveness of my birth control pill.Thank you in advance!
