Treatment Summary
Levofloxacin is an antibiotic that is 8 to 128 times more effective against both gram-positive and gram-negative bacteria than the other isomer of racemic ofloxacin. It is part of the third generation of fluoroquinolones, commonly referred to as the “respiratory quinolones” due to its effectiveness against bacteria associated with respiratory infections. Levofloxacin was first approved by the FDA in 1996, and was quickly approved in many other countries after.

Effectiveness
How Levaquin Affects Patients
Levofloxacin is an antibiotic that works by stopping bacteria from reproducing. It usually only needs to be taken once or twice per day and can be effective against certain types of bacteria, like Chlamydia and Legionella. However, some bacteria can become resistant to levofloxacin due to changes in their DNA. Cross-resistance between levofloxacin and other antibiotics is unlikely because they work differently. Different areas have different bacteria, so it is important to check local antibiotic resistance patterns before taking levofloxacin.
How Levaquin works in the body
Levofloxacin is an antibiotic that works by blocking two key enzymes in bacteria: DNA gyrase and topoisomerase IV. DNA gyrase helps with DNA replication and topoisomerase IV helps with cell division. Levofloxacin binds to the enzymes and stops them from working, which prevents DNA replication and cell division and ultimately kills the bacteria.

The risk or severity of QTc prolongation can be increased when Levofloxacin is combined with Arsenic trioxide.
Levaquin Toxicity & Overdose Risk
Levofloxacin has a low risk of acute toxicity. In tests, high doses of levofloxacin caused symptoms such as unsteadiness, drooping eyelids, reduced movement, difficulty breathing, shaking, and seizures. If someone overdoses on levofloxacin, they should have their stomach emptied and receive general supportive care. It is also recommended to monitor the patient's heart rhythm to make sure it is within a normal range. Dialysis is not very effective in removing levofloxacin from the body in cases of overdose.

Patient Q&A Section about levaquin
These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.
Why was Levaquin taken off the market?
"Kelsey Buckholtz, a spokeswoman for Janssen, said that they decided to discontinue Levaquin because there are a lot of other treatment options available and they want to focus on developing new medicines."
Answered by AI
What is Levaquin used to treat?
"It will not work for viral infections (such as common cold, flu).
Levofloxacin is used to treat a variety of bacterial infections. This medication belongs to a class of drugs known as quinolone antibiotics. These drugs work by interfering with the production of essential proteins needed by bacteria to survive. This particular antibiotic is effective against a wide variety of bacteria. However, it is important to remember that this drug will not work against viral infections."
Answered by AI
Is Levaquin and amoxicillin the same?
"Both Levaquin and amoxicillin are antibiotics used to treat infections. Levaquin is a fluoroquinolone and amoxicillin is a penicillin. They are both used to treat infections of the lungs, airways, skin, urinary tract, and ears. The main difference between the two drugs is the conditions they are used to treat."
