Pneumonia: Treatment of hospital-acquired or community-acquired lung infections. Sinusitis: Severe bacterial infection of the sinuses. Complicated Urinary Tract Infections (UTIs): Including kidney infections (pyelonephritis). Skin Infections: Treatment of complicated skin and soft tissue infections (e.g., cellulitis, abscesses). Chronic Bronchitis: Acute worsening of long-term lung inflammation. Prostatitis: Bacterial infection of the prostate gland.
Levofloxacin is a "bactericidal" antibiotic, meaning it kills bacteria directly: DNA Inhibition: It enters the bacterial cell and inhibits two key enzymes: DNA gyrase and topoisomerase IV. Halting Reproduction: These enzymes are essential for bacteria to unfold, repair, and replicate their DNA. Cell Death: Without the ability to manage its DNA, the bacteria cannot multiply and eventually die off, allowing the body's immune system to clear the remaining infection.
Common: Nausea, diarrhea, headache, dizziness, and constipation. Neurological: Sleep problems (insomnia) or "jitters." Photosensitivity: Skin becomes extremely sensitive to sunlight/UV rays (easier to burn). Serious (Black Box Warning): Tendonitis or tendon rupture (specifically the Achilles tendon). CNS Effects: In rare cases, it can cause tremors, anxiety, or confusion.
Yes, 750mg is a high-strength dose typically used for more severe infections or for shorter treatment courses (often 5 days) compared to the standard 250mg or 500mg doses.
No. You must complete the full course prescribed by your doctor. Stopping early can allow the strongest bacteria to survive and develop antibiotic resistance.
Levofloxacin is linked to a rare risk of tendon inflammation or rupture. It is best to avoid strenuous physical activity or heavy lifting during treatment and for a few days after.
It is best to take it with water. Levofloxacin can increase the effects of caffeine, making you feel more 'jittery,' anxious, or causing a racing heart.
Avoid antacids containing magnesium, aluminum, or calcium within 2 hours of taking Levofloxacin. They can bind to the antibiotic and prevent it from being absorbed.
Yes. It can cause severe sunburns quickly. Wear sunscreen, protective clothing, and avoid tanning beds while taking this medication.
You must inform your doctor. Fluoroquinolones like Levofloxacin can lower the seizure threshold and may not be suitable for people with seizure disorders.
It can be taken with or without food, but taking it at the same time every day with plenty of water is the most important factor for success.
No. Antibiotics only work against bacteria. They have no effect on viruses like the flu, COVID-19, or the common cold.
Seek immediate help if you experience sudden pain, swelling, or bruising in your joints (tendons), or if you experience watery/bloody diarrhea or severe mood changes.
