Levofloxacin: A Potent Antibiotic

Levofloxacin is a fluoroquinolone antibiotic used to treat bacterial infections like pneumonia, sinusitis, and urinary tract infections. It works by inhibiting bacterial DNA replication, ensuring effective treatment. Always follow your doctor's dosage instructions.

How Levofloxacin Works

This antibiotic targets bacterial enzymes, preventing DNA synthesis and stopping infection spread. It’s effective against gram-positive and gram-negative bacteria, making it versatile for respiratory and skin infections.

Common Uses of Levofloxacin

Levofloxacin treats bronchitis, prostatitis, and skin infections. It’s also prescribed for anthrax exposure. Avoid unnecessary use to prevent antibiotic resistance.

Dosage Guidelines

Typical doses range from 250mg to 750mg daily, depending on infection severity. Take with water, and avoid dairy or antacids within 2 hours to ensure absorption.

Side Effects to Monitor

Common side effects include nausea, diarrhea, and dizziness. Rare but serious effects include tendon rupture and nerve damage. Contact your doctor if symptoms worsen.

Precautions with Levofloxacin

Avoid alcohol and prolonged sun exposure. Inform your doctor of any heart or kidney conditions before use. Not recommended for pregnant women or children.

Levofloxacin vs Other Antibiotics

Compared to penicillin, levofloxacin has a broader spectrum and is better for resistant bacteria. However, it’s not a first-line treatment for mild infections due to side effect risks.

Storage and Handling
