Most antibiotics do not affect contraception. It's now thought that the only types of antibiotic that interact with hormonal contraception and make it less effective are rifampicin-like antibiotics. These can be used to treat or prevent diseases, including tuberculosis and meningitis.
Similarly, you may ask, what antibiotics make the pill less effective?
Only one antibiotic is known to make the pill less effective. That is rifampin, a special medication used to treat tuberculosis. The brand names include Rifadin and Rimactane. Other antibiotics do not make the pill less effective.
Additionally, how likely is it to get pregnant while on antibiotics?
What Are the Chances of Getting Pregnant While Taking Antibiotics? Taking antibiotics while trying to conceive is highly unlikely to influence your chances. Antibiotic therapy may help re-establish the well-being of the reproductive system which may have been weakened by a bacterial infection.
How long should you wait to get pregnant after antibiotics?
If infection is documented in both the cervix and the uterine lining, however, especially with antisperm antibodies already detected, patients may have to wait six to ten months after antibiotic therapy before a pregnancy can be expected.
What cancels out birth control?
So far, the only antibiotic that studies show interferes with birth control is rifampin (Rifadin), a drug used to treat tuberculosis. Rifampin causes irregular periods. It raises the risk that you may get pregnant even if you use your birth control the right way.
