Does the antibiotic Augmentin affect the effectiveness of contraceptive pills and do you therefore need to protect yourself additionally?

Both when taking the antibiotic Augmentin and 7 days after its completion, it is recommended to use additional methods of contraception (e.g. a condom). Antibiotics, including Augmentin, can disrupt the composition of the bacterial flora in the gut, which is necessary to convert the hormones contained in all types of pills into active forms. This limits their absorption from the pills into the blood, thereby reducing contraceptive effectiveness.
