Rising Health, LLC

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

Discontinue moxifloxacin hydrochloride immediately and avoid the use of fluoroquinolones, including moxifloxacin hydrochloride, in patients who experience any of these serious adverse reactions [see Warnings and Precautions (5.1)].

  • Fluoroquinolones, including moxifloxacin hydrochloride, may exacerbate muscle weakness in patients with myasthenia gravis. Avoid moxifloxacin hydrochloride in patients with known history of myasthenia gravis [see Warnings and Precautions (5.5)].
  • Because fluoroquinolones, including moxifloxacin hydrochloride, have been associated with serious adverse reactions [see Warnings and Precautions (5.1 to 5.14)], reserve moxifloxacin hydrochloride for use in patients who have no alternative treatment options for the following indications:
  • Acute bacterial sinusitis [see Indications and Usage (1.6)]
  • Acute bacterial exacerbation of chronic bronchitis [see Indications and Usage (1.7)]

1 INDICATIONS AND USAGE

1.1 Community Acquired Pneumonia

Moxifloxacin tablets are indicated in adult patients for the treatment of Community Acquired Pneumonia caused by susceptible isolates of Streptococcus pneumoniae (including multi-drug resistant Streptococcus pneumoniae [MDRSP]), Haemophilus influenzae, Moraxella catarrhalis, methicillin-susceptible Staphylococcus aureus, Klebsiella pneumoniae, Mycoplasma pneumoniae, or Chlamydophila pneumoniae [see Clinical Studies (14.3)].

MDRSP isolates are isolates resistant to two or more of the following antibacterial drugs: penicillin (minimum inhibitory concentrations [MIC] ≥ 2 mcg/mL), 2nd generation cephalosporins (for example, cefuroxime), macrolides, tetracyclines, and trimethoprim/sulfamethoxazole.

1.2 Uncomplicated Skin and Skin Structure Infections

Moxifloxacin tablets are indicated in adult patients for the treatment of Uncomplicated Skin and Skin Structure Infections caused by susceptible isolates of methicillin-susceptible Staphylococcus aureus or Streptococcus pyogenes [see Clinical Studies (14.4)].

1.3 Complicated Skin and Skin Structure Infections

Moxifloxacin tablets are indicated in adult patients for the treatment of Complicated Skin and Skin Structure Infections caused by susceptible isolates of methicillin-susceptible Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, or Enterobacter cloacae [see Clinical Studies (14.5)].

1.4 Complicated Intra-Abdominal Infections

Moxifloxacin tablets are indicated in adult patients for the treatment of Complicated Intra-Abdominal Infections (cIAI) including polymicrobial infections such as abscess caused by susceptible isolates of Escherichia coli, Bacteroides fragilis, Streptococcus anginosus, Streptococcus constellatus, Enterococcus faecalis, Proteus mirabilis, Clostridium perfringens, Bacteroides thetaiotaomicron, or Peptostreptococcus species [see Clinical Studies (14.6)].

1.5 Plague

Moxifloxacin tablets are indicated in adult patients for the treatment of plague, including pneumonic and septicemic plague, due to susceptible isolates of Yersinia pestis and prophylaxis of plague in adult patients. Efficacy studies of moxifloxacin could not be conducted in humans with plague for feasibility reasons. Therefore this indication is based on an efficacy study conducted in animals only [see Clinical Studies (14.7)].

1.6 Acute Bacterial Sinusitis

Moxifloxacin tablets are indicated in adult patients (18 years of age and older) for the treatment of acute bacterial sinusitis (ABS) caused by susceptible isolates of Streptococcus pneumoniae, Haemophilus influenzae , or Moraxella catarrhalis [see Clinical Studies (14.1)].

Because fluoroquinolones, including moxifloxacin tablets, have been associated with serious adverse reactions [see Warnings and Precautions (5.1 to 5.14)] and for some patients ABS is self-limiting, reserve moxifloxacin tablets for treatment of ABS in patients who have no alternative treatment options.

1.7 Acute Bacterial Exacerbation of Chronic Bronchitis

Moxifloxacin tablets are indicated in adult patients for the treatment of Acute Bacterial Exacerbation of Chronic Bronchitis (ABECB) caused by susceptible isolates of Streptococcus pneumoniae, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, methicillin-susceptible Staphylococcus aureus, or Moraxella catarrhalis [see Clinical Studies (14.2)].

Because fluoroquinolones, including moxifloxacin tablets, have been associated with serious adverse reactions [see Warnings and Precautions (5.1 to 5.14)] and for some patients ABECB is self-limiting, reserve moxifloxacin tablets for treatment of ABECB in patients who have no alternative treatment options.

1.8 Usage

To reduce the development of drug-resistant bacteria and maintain the effectiveness of moxifloxacin tablets and other antibacterial drugs, moxifloxacin tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

2 DOSAGE AND ADMINISTRATION

2.1 Dosage in Adult Patients

The dose of moxifloxacin is 400 mg (orally) once every 24 hours. The duration of therapy depends on the type of infection as described in Table 1.

5 WARNINGS AND PRECAUTIONS

5.1 Disabling and Potentially Irreversible Serious Adverse Reactions Including Tendinitis and Tendon Rupture, Peripheral Neuropathy, and Central Nervous System Effects

Fluoroquinolones, including moxifloxacin hydrochloride, 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 hydrochloride. Patients of any age or without pre-existing risk factors have experienced these adverse reactions [see Warnings and Precautions (5.2,5.3,5.4)].

Discontinue moxifloxacin hydrochloride immediately at the first signs or symptoms of any serious adverse reaction. In addition, avoid the use of fluoroquinolones, including moxifloxacin hydrochloride, in patients who have experienced any of these serious adverse reactions associated with fluoroquinolones.

5.2 Tendinitis and Tendon Rupture

Fluoroquinolones, including moxifloxacin hydrochloride, have been associated with an increased risk of tendinitis and tendon rupture in all ages [see Warnings and Precautions (5.1) and Adverse Reactions (6.2)]. 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 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 hydrochloride immediately if the patient experiences pain, swelling, inflammation or rupture of a tendon. Patients should be advised to rest at the first sign of tendinitis or tendon rupture, and to contact their healthcare provider regarding changing to a non-quinolone antimicrobial drug. Avoid fluoroquinolones, including moxifloxacin hydrochloride, in patients who have a history of tendon disorders or who have experienced tendinitis or tendon rupture [see Adverse Reactions (6.2)].

5.3 Peripheral Neuropathy

Fluoroquinolones, including moxifloxacin hydrochloride, have been associated with an increased risk of peripheral neuropathy. Cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving fluoroquinolones including moxifloxacin hydrochloride. Symptoms may occur soon after initiation of moxifloxacin hydrochloride and may be irreversible in some patients [see Warnings and Precautions (5.1) and Adverse Reactions (6.1, 6.2)].

Discontinue moxifloxacin hydrochloride immediately if the patient experiences symptoms of peripheral neuropathy including pain, burning, tingling, numbness, and/or weakness or other alterations of sensation including light touch, pain, temperature, position sense, and vibratory sensation. Avoid fluoroquinolones, including moxifloxacin hydrochloride, in patients who have previously experienced peripheral neuropathy.

5.4 Central Nervous System Effects

Psychiatric Adverse Reactions

Fluoroquinolones, including moxifloxacin hydrochloride, have been associated with an increased risk of psychiatric adverse reactions, including: toxic psychosis, hallucinations, or paranoia; depression or suicidal thoughts or acts; anxiety, agitation, or nervousness; confusion, delirium, disorientation, or disturbances in attention; insomnia or nightmares; memory impairment. These adverse reactions may occur following the first dose. If these reactions occur in patients receiving moxifloxacin hydrochloride, discontinue moxifloxacin hydrochloride immediately and institute appropriate measures [see Adverse Reactions (6.1, 6.2)].
Central Nervous System Adverse Reactions
Fluoroquinolones, including moxifloxacin hydrochloride, have been associated with an increased risk of seizures (convulsions), increased intracranial pressure (including pseudotumor cerebri), dizziness, and tremors. As with all fluoroquinolones, use moxifloxacin hydrochloride with caution in patients with known or suspected CNS disorders (for example, severe cerebral arteriosclerosis, epilepsy) or in the presence of other risk factors that may predispose to seizures or lower the seizure threshold. These adverse reactions may occur following the first dose. If these reactions occur in patients receiving moxifloxacin hydrochloride, discontinue moxifloxacin hydrochloride immediately and institute appropriate measures [see Drug Interactions (7.4)Adverse Reactions (6.1, 6.2), and Patient Counseling Information (17)].
