Does levaquin affect birth control?

Levaquin probably does not affect birth control according to WebMD. A doctor or pharmacist can advise a patient on whether additional birth control should be used.

Most antibiotics usually do not have an adverse effect on hormone-based birth control such as pills, rings or patches. Some antibiotics can potentially decrease their effectiveness, increasing the risk of pregnancy.

Any patient who is concerned about the possibility of becoming pregnant should ask her doctor or pharmacist about taking levaquin and hormonal birth control. The medical professional can tell her whether or not she should use a secondary form of birth control, such as condoms, while taking this antibiotic.
