The birth control pill lowers your sex drive.
FACT. My friend was right—it can. Numerous articles cite women who report a lowered libido on the pill and a study published in the Journal of Sexual Medicine suggests that the pill may reduce a woman’s sex drive for months after discontinuation. “30 to 40 percent of women on birth control pills have decreased libido,” study co-author Dr. Andrew Guay, director of the Center for Sexual Health/Endocrinology at the Lahey Clinic in Boston, told HealthDay News. But not all experts agree. Dr. Rahimian acknowledges that some women experience a lowered sex drive, but says, “For most women, this is not a major issue.”

Antibiotics reduce the effectiveness of a pill.
MYTH. This is a major concern for many women and there are a lot of varying opinions out there. Some health practitioners recommend using back-up contraception while taking antibiotics due to a concern about an interaction between antibiotics and the pill. But according to most official sources, including Planned Parenthood, there is only one antibiotic, Rifampin, known to interact with the pill and it’s primarily used to treat tuberculosis. “The majority of commonly used antibiotics do not reduce the effectiveness of the pill,” affirms Dr. Rahimian. But since there’s no conclusive evidence just yet, it’s best to use that second form of protection if you’re on any type of antibiotic.
