FDA Warnings and Levaquin Side Effects

Levaquin (a fluoroquinalone) is a prescription drug that is a synthetic antibiotic drug used to treat lung, sinus, skin and urinary tract infections. This drug works on bacterial infections and not viral. The drug was approved by the FDA in 1996. Since then a number of serious Levaquin Side Effects have been reported. The FDA has required warnings be placed on all packaging. These warnings have had many revisions. Finally the FDA required a “black box” warning on all Levaquin packaging in 2008 to make sure consumers understand the increased risk of a Levaquin tendon ruptures. Black box warnings are the most serious warnings the FDA can require a manufacturer to use and may be a prelude to a recall. Listed below are the Levaquin Side Effects as listed in the “black box” warning.

  • Liver dysfunction

  • Central nervous system damage (convulsions, depression, anxiety, confusion, insomnia)

  • Allergic reaction

  • Colitis

  • Arrhythmias

  • Blood sugar changes

  • Photosensitivity

  • Joint problems

  • Skin reactions

  • kidney dysfunction

  • Urinary tract infections

Levaquin has been reported to initiate a number of skin infections including: skin ulcers, abscesses, boils, furuncles, carbuncles and impetigo. This list is not complete. Check with the label on your prescription or visit the Levaquin website.

Your doctor needs to know your complete medical history and what other medications you are taking including prescriptions, vitamins and botanicals. You need to let your doctor know if you are taking Coumadin, Warfarin, anti-inflammatories, steroids or diabetic medications as they have been known to interact with Levaquin.

Overdosing with Levaquin has serious consequences. Do not overdose. If you overdose, seek immediate medical attention. Symptoms of an overdose include: tremors, muscle weakness, loss of coordination, seizures, sweating and difficulty breathing (anaphylactic shock).

The fluoroquinalone class of molecules are known to be involved with tendon ruptures and in partticular an Achilles tendon rupture which Levaquin shares.

Levaquin Side Effects also include intestinal infections with Clostridium difficile generating colitis. Even of greater concern is levaquin’s ability to generate resistant strains of bacteria even more so than other fluoroquinalones. For that reason other fluoroquinalones such as Ciprofloxacin are often prescribed instead to try to prevent resistance.

As you can see, Levaquin Side Effects can be severe and caution needs to be taken when using this antibiotic and it should be used only when necessary.
