Levofloxacin Tablet: Benefits, Side Effects and Precautions
Written by Medicover Team and Medically Reviewed by Dr Prerit Rao, ENT
Levofloxacin, commonly sold under the brand name Levaquin, is a potent antibiotic. It's used to treat a wide range of bacterial infections including acute sinusitis, pneumonia, H. Pylori, urinary tract infections, chronic prostatitis, and certain forms of gastroenteritis.
Levofloxacin belongs to a class of antibiotics known as quinolones. It is effective against various bacterial infections but not against viral infections like the common cold or flu. Misuse or unnecessary use of antibiotics can reduce their effectiveness.
Always consult your doctor about the use and potential complications of this drug.
Read the Drug Guide provided by your pharmacist before starting levofloxacin and each time you get a refill. Take this medication orally, usually once a day with or without food. Drink plenty of water unless your doctor advises otherwise.
Dosage Tips:
Levofloxacin works by inhibiting bacterial enzymes (DNA gyrase and topoisomerase IV) that are essential for DNA replication and repair. This action kills the bacteria and prevents them from multiplying.
In simple terms: Levofloxacin stops bacteria from reproducing, helping the body clear the infection.
