Moxifloxacin belongs to a class of antibiotics known as fluoroquinolones, also known as "quinolones." These medications work 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 Moxifloxacin
Some general considerations for those taking moxifloxacin include the following:
- Moxifloxacin comes in tablet and injectable form. It is usually taken once a day.
- You can take the drug with food or on an empty stomach. If moxifloxacin bothers your stomach, try taking it with food.
- Moxifloxacin 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. Moxifloxacin will not work adequately if you stop taking it too soon.
The dose of moxifloxacin your healthcare provider recommends will vary, depending on a number of factors, including:
- The type of infection and bacteria
- Other medical conditions you may have
- Other medications you may be taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
What If I Take an Overdose of Moxifloxacin?
Based on the results of animal studies, people who take an overdose may experience effects such as (but not limited to):
- Drowsiness
- Shakiness (tremor)
- Seizures
- Vomiting
- Diarrhea
- An irregular heart rhythm (arrhythmia).
If you happen to overdose on moxifloxacin, seek immediate medical attention.
What Should I Do If I Miss a Dose?
If you do not take your moxifloxacin 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. Do not take a double dose. Try not to miss doses, as this increases the risk of developing an antibiotic-resistant infection.
