Doxycycline, a common antibiotic, can reduce the effectiveness of certain hormonal birth control methods. This happens because it affects the liver’s metabolism of hormones, potentially lowering their levels in the bloodstream. The impact varies depending on the type of birth control and the dosage of doxycycline.
Combined Oral Contraceptives (COCs)
Studies show doxycycline may decrease the effectiveness of combined oral contraceptives (the pill containing both estrogen and progestin). While some research indicates a relatively small impact, it’s prudent to use a backup method of contraception, such as condoms, while taking doxycycline and for at least seven days after completing the antibiotic course. Consult your doctor for personalized advice.
Other Hormonal Methods
The effect of doxycycline on other hormonal methods, such as the patch, the ring, or injections, is less well-studied. However, similar interactions are possible. It’s advisable to discuss potential interactions with your healthcare provider before starting or continuing any hormonal birth control while taking antibiotics. Using a backup method during and shortly after doxycycline treatment is a precautionary measure. This ensures continued protection against unintended pregnancy.
