Levaquin
® (
levofloxacin) is a prescription antibiotic approved to treat a variety of different infections. It is also approved to prevent infection after exposure to inhaled
anthrax.
Levaquin is manufactured by Ortho-McNeil Pharmaceutical, Inc.
Levaquin belongs to a group of medications known as fluoroquinolones, sometimes known just as "quinolones" for short. It works by interfering with two important bacterial enzymes (topoisomerase IV and DNA gyrase). These enzymes are necessary for bacteria to be able to copy and repair DNA (important steps required in order for bacteria to multiply).
When and How to Take Levaquin
Some general considerations include the following:
- Levaquin comes as tablets, an oral solution (liquid), and an injection form. It is usually taken once a day.
- You can take the tablets with food or on an empty stomach. However, the oral solution must be taken at least one hour before or two hours after a meal.
- Levaquin can be taken at any time of the day; however, be sure to take it at the same time each day (to make sure there is approximately 24 hours between doses).
- For the medication to work properly, it must be taken as prescribed. Levaquin will not work if you stop taking it too soon.
The dose of Levaquin that your healthcare provider recommends will vary depending on a number of factors, including:
- The type of infection and bacteria
- Your age and weight
- Other medical conditions you may have
- Other medications you may currently be taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
As with any medicine, side effects are possible with Levaquin. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. Serious side effects are less common. Some of the common side effects include, but are not limited to:

What Should I Do If I Miss a Dose?
If you do not take your Levaquin as scheduled, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule.
