Levaquin 750 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Levaquin 750 mg?

Levaquin 750 mg is a prescription antibiotic containing levofloxacin, a medicine in the fluoroquinolone class of antibiotics. It is used to treat a variety of bacterial infections in adults by stopping the growth and spread of bacteria.

Levaquin is effective against many types of bacteria, but it does not treat viral infections such as the common cold or influenza. To help reduce antibiotic resistance, it should only be used for infections caused by bacteria that are susceptible to levofloxacin.

Levaquin is available as:

• Oral solution.
• Intravenous (IV) infusion for hospital use.

The 750 mg tablet is one of the higher strengths and is prescribed for specific infections and treatment durations determined by a healthcare provider.

How Levaquin Works

Levofloxacin works by blocking bacterial enzymes called DNA gyrase and topoisomerase IV, which bacteria need to:

• Replicate their DNA.
• Grow and multiply.
• Repair damaged genetic material.

By interfering with these enzymes, Levaquin kills susceptible bacteria and helps clear the infection.
