Levaquin: What You Need to Know About This Antibiotic
Introduction to Levaquin
Levaquin, known generically as levofloxacin, is a broad-spectrum antibiotic that belongs to the fluoroquinolone drug class. It is primarily used to treat a variety of bacterial infections, including respiratory tract infections, urinary tract infections, and skin infections. This medication works by inhibiting the enzymes that bacteria need to replicate and repair their DNA, thus killing the bacteria and stopping the infection.
Mechanism of Action
Levaquin exerts its antibacterial effects by targeting bacterial topoisomerase IV and DNA gyrase, essential enzymes in bacterial DNA replication and repair. By interfering with these enzymes, Levaquin interrupts the DNA synthesis process, leading to the death of susceptible bacteria.
Indications for Use
Levaquin is prescribed for treating several types of bacterial infections, including:
- Community-acquired pneumonia
- Acute bacterial sinusitis
- Chronic bronchitis
- Complicated urinary tract infections (UTIs)
- Acute pyelonephritis
- Skin and soft tissue infections
- Plague (as part of emergency treatment)
Dosage Recommendations
The dosage of Levaquin varies depending on the type and severity of the infection, as well as the patient’s renal function. Common dosage recommendations include:
- Community-acquired pneumonia: 500 mg to 750 mg once daily for 7-14 days
- Acute bacterial sinusitis: 750 mg once daily for 5 days
- Chronic bronchitis: 500 mg once daily for 7 days
- Complicated UTIs and acute pyelonephritis: 250 mg to 750 mg once daily for 7-14 days
- Skin infections: 500 mg once daily for 7-14 days
Always adhere to your healthcare provider’s instructions and never self-adjust your dosage.

- Nausea and vomiting
- Diarrhea
- Headache
- Dizziness
- Insomnia
- Risk of tendonitis and tendon rupture
- Peripheral neuropathy
- Central nervous system effects, such as seizures and hallucinations
