BOX WARNING (revised)
 

WARNING: SERIOUS ADVERSE REACTIONS INCLUDING TENDINITIS, TENDON RUPTURE, PERIPHERAL NEUROPATHY, CENTRAL NERVOUS SYSTEM EFFECTS AND EXACERBATION OF MYASTHENIA GRAVIS 

  • Fluoroquinolones, including MOXIFLOXACIN®, have been associated with disabling and potentially irreversible serious adverse reactions that have occurred together including:
    • Tendinitis and tendon rupture
    • Peripheral neuropathy
    • Central nervous system effects
  • Discontinue MOXIFLOXACIN immediately and avoid the use of fluoroquinolones, including MOXIFLOXACIN, in patients who experience any of these serious adverse reactions. Fluoroquinolones, including MOXIFLOXACIN, may exacerbate muscle weakness in patients with myasthenia gravis. Avoid MOXIFLOXACIN in patients with known history of myasthenia gravis.
  • Because fluoroquinolones, including MOXIFLOXACIN, have been associated with serious adverse reactions, reserve MOXIFLOXACIN for use in patients who have no alternative treatment options for the following indications:
    • Acute exacerbation of chronic bronchitis
    • Acute uncomplicated cystitis
    • Acute sinusitis

WARNINGS AND PRECAUTIONS

Disabling and Potentially Irreversible Serious Adverse Reactions Including Tendinitis and Tendon Rupture, Peripheral Neuropathy, and Central Nervous System Effects (addition) 
  • Fluoroquinolones, including MOXIFLOXACIN, have been associated with disabling and potentially irreversible serious adverse reactions from different body systems that can occur together in the same patient. Commonly seen adverse reactions include tendinitis, tendon rupture, arthralgia, myalgia, peripheral neuropathy, and central nervous system effects (hallucinations, anxiety, depression, insomnia, severe headaches, and confusion). These reactions can occur within hours to weeks after starting MOXIFLOXACIN. Patients of any age or without pre-existing risk factors have experienced these adverse reactions.
  • Discontinue MOXIFLOXACIN immediately at the first signs or symptoms of any serious adverse reaction. In addition, avoid the use of fluoroquinolones, including MOXIFLOXACIN, in patients who have experienced any of these serious adverse reactions associated with fluoroquinolones.
Tendinitis and Tendon Rupture replaces Tendinopathy 
 
  • Fluoroquinolones, including MOXIFLOXACIN, have been associated with an increased risk of tendinitis and tendon rupture in all ages. This adverse reaction most frequently involves the Achilles tendon, and has also been reported with the rotator cuff (the shoulder), the hand, the biceps, the thumb, and other tendons. Tendinitis or tendon rupture can occur, within hours or days of starting MOXIFLOXACIN, or as long as several months after completion of fluoroquinolone therapy... Tendinitis and tendon rupture can occur bilaterally.
  • The risk of developing fluoroquinolone-associated tendinitis and tendon rupture is increased in patients over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart or lung transplants. Other factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis. Tendinitis and tendon rupture have also occurred in patients taking fluoroquinolones who do not have the above risk factors. Discontinue MOXIFLOXACIN immediately if the patient experiences pain, swelling, inflammation or rupture of a tendon. Avoid fluoroquinolones, including MOXIFLOXACIN, in patients who have a history of tendon disorders or have experienced tendinitis or tendon rupture.
Peripheral Neuropathy (new sentences added) 
  • Fluoroquinolones, including MOXIFLOXACIN, have been associated with an increased risk of peripheral neuropathy. Cases of sensory…
  • …minimize the development of an irreversible condition…Avoid fluoroquinolones, including MOXIFLOXACIN, in patients who have previously experienced peripheral neuropathy.

ADVERSE REACTIONS 

  • The following serious and otherwise important adverse drug reactions are discussed in greater detail in other sections of labeling:
    • Disabling and Potentially Irreversible Serious Adverse Reactions (addition)
    • Tendinitis and Tendon Rupture (replaces Tendon Effects)

PATIENT COUNSELING INFORMATION

Serious Adverse Reactions
  • Advise patients to stop taking MOXIFLOXACIN if they experience an adverse reaction and to call their healthcare provider for advice on completing the full course of treatment with another antibacterial drug. Inform patients of the following serious adverse reactions that have been associated with MOXIFLOXACIN or other fluoroquinolone use:
    • Disabling and potentially irreversible serious adverse reactions that may occur together: Inform patients that disabling and potentially irreversible serious adverse reactions, including tendinitis and tendon rupture, peripheral neuropathies, and central nervous system effects, have been associated with use of MOXIFLOXACIN and may occur together in the same patient. Inform patients to stop taking MOXIFLOXACIN immediately if they experience an adverse reaction and to call their healthcare provider. (addition) 
    • Tendinitis and tendon rupture replaces Tendon Disorders

MEDICATION GUIDE

What is the most important information I should know about MOXIFLOXACIN?

  • Tendon rupture or swelling of the tendon (tendinitis).
    • Stop taking MOXIFLOXACIN immediately and get medical help right away…
    • Worsening of myasthenia gravis (a problem that causes muscle weakness). Tell your healthcare provider if you have a history of myasthenia gravis before you start taking MOXIFLOXACIN. (addition)

What is MOXIFLOXACIN?

  • MOXIFLOXACIN should not be used in patients with acute exacerbation of chronic bronchitis, acute uncomplicated cystitis, and sinus infections, if there are other treatment options available.
  • MOXIFLOXACIN should not be used as the first choice of antibacterial medicine to treat lower respiratory tract infections cause by a certain type of bacterial called Streptococcus pneumonia.

Before you take MOXIFLOXACIN, tell your healthcare provider if you:

  • have a disease that causes muscle weakness (myasthenia gravis); MOXIFLOXACIN should not be used in patients who have a known history of myasthenia gravis.
  • have nerve problems; MOXIFLOXACIN should not be used in patients who have a history of a nerve problem called peripheral neuropathy
