Levaquin is a prescription medicine indicated to treat several types of bacterial infections. It can be used for the following conditions: 

  • Nosocomial pneumonia 
  • Community-acquired pneumonia 
  • Complicated and uncomplicated skin and skin structure infections 
  • Chronic bacterial prostatitis 
  • Acute bacterial exacerbation of chronic bronchitis 
  • Acute bacterial sinusitis 
  • Urinary tract infections (UTI) 
  • Acute pyelonephritis 

Levaquin is also indicated for the treatment of individuals exposed to anthrax or specific types of plague. 

Classified as a fluoroquinolone, Levaquin halts bacterial growth by impeding the vital topoisomerase IV and DNA gyrase enzymes necessary for bacterial DNA replication, transcription, repair, and recombination. 

Uses and Dosage 

Before using Levaquin, and with every subsequent refill, carefully review its medication guide and patient information leaflet. Do not hesitate to consult with your physician or pharmacist for any questions or uncertainties. 

Levaquin’s dosage and duration of intake may vary per individual based on their medical condition and response to the treatment. For pediatric patients, weight is also considered. 

Typically, Levaquin is taken once daily as prescribed by the doctor without regard to food intake. Adequate hydration is recommended during this medication to maintain proper renal function. 

For optimal efficacy, adhere to a consistent schedule of Levaquin administration at evenly spaced intervals, as directed by your physician. Avoid deviating from the prescribed dosage or frequency of intake, whether by increasing or decreasing it. 

Consistently follow the prescribed dosage regimen of this medication until the full course is completed, even if symptoms abate within a few days.  

Skipping doses of Levaquin may heighten the likelihood of contracting a drug-resistant infection, while premature cessation can lead to the recurrence of the infection.
