  • Summary of Isoniazid vs. Avelox

    Summary for Antimycobacterial agent
    Prescription only

    Isoniazid is an antimycobacterial agent for treating and preventing tuberculosis (TB) in children and adults. It's available as a generic oral tablet and solution, usually taken daily or a few times a week, depending on your dose. For treating active TB, you'll likely need to take it along with other TB medications (like rifampin, pyrazinamide, and ethambutol) to prevent antibiotic resistance. Serious side effects include severe liver injury. It's also known to interact with many foods and medications.

    Summary for Fluoroquinolone antibiotic
    Prescription only

    Moxifloxacin (Avelox) is a fluoroquinolone antibiotic. It can treat different types of infections, including certain skin infections and lung infections, in adults. But because moxifloxacin (Avelox) can cause serious side effects, such as tendon rupture and nerve damage, it's usually only prescribed for more serious infections or when safer options aren't available. Moxifloxacin (Avelox) is taken by mouth, typically once daily. Some of the more common side effects of this medication include nausea, diarrhea, and headache. Moxifloxacin is generic only, brand-name Avelox is no longer available.
