Although the degrees to which antibiotics may affect hormonal birth control vary, there are certain antibiotics which doctors say can cause decreased effectiveness. Antibiotics that are listed as interfering include:
- Rifampin
- Penicillin
- Amoxicillin
- Sulfonamide
- Ampicillin
- Cotrimoxazole
- Tetracycline
- Griseofulvin
- Minocycline
- Metronidazole
- Nitrofurantoin
If you are taking any of these antibiotics while using birth control pills your doctor should recommend that you use a back-up method of birth control (ie. condom). Despite the fact there is little evidence supporting a massive increase in pregnancies with antibiotic use, it is better to be safe than sorry. Use the back-up method during the run of your antibiotic and continue for one week afterwards.
Speak with your doctor if you have any concerns or questions about antibiotics and the effectiveness of your birth control.
