  • Summary of Metronidazole vs. Cipro

    Summary for Nitroimidazole antibiotic
    Prescription only

    Metronidazole (Flagyl) is an oral antibiotic for adults and children. It's used to treat certain bacterial and parasitic infections, including bacterial vaginosis (a type of vaginal bacteria infection) and trichomoniasis (a sexually transmitted infection, or STI). Metronidazole (Flagyl) is taken by mouth, typically 3 times a day. Some common side effects of this medication include diarrhea, nausea, and vomiting. Avoid drinking alcohol while taking and for 3 days after stopping metronidazole (Flagyl) because this combination can cause a serious reaction. Metronidazole (Flagyl) is available as a lower-cost generic.

    Summary for Fluoroquinolone antibiotic
    Prescription only

    Ciprofloxacin (Cipro) is a fluoroquinolone antibiotic. It can treat many types of bacterial infections, including sinus infections and urinary tract infections (UTIs). But because ciprofloxacin (Cipro) can cause serious side effects, such as tendon rupture and nerve damage, it's usually only prescribed for more serious infections or when there aren't any safer options. Ciprofloxacin (Cipro) is taken by mouth, typically twice daily. It's available as a pill and oral solution. Some of the more common side effects of this medication include nausea and diarrhea.
