This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or your treatment.  

What is the most important information I should know about moxifloxacin hydrochloride tablets?

Moxifloxacin hydrochloride tablet belongs to a class of antibiotics called fluoroquinolones. Moxifloxacin hydrochloride tablets can cause serious side effects that can happen at the same time and could result in death. If you get any of the following serious side effects, you should stop taking moxifloxacin tablets and get medical help right away. Talk with your healthcare provider about whether you should continue to take moxifloxacin hydrochloride tablets.  

1. Tendon rupture or swelling of the tendon (tendinitis).

• Tendon problems can happen in people of all ages who take moxifloxacin hydrochloride tablets. Tendons are tough cords of tissue that connect muscles to bones. Symptoms of tendon problems may include:
  • Pain, swelling, tears and inflammation of tendons including the back of the ankle   (Achilles), shoulder, hand, or other tendon sites.

• The risk of getting tendon problems while you take moxifloxacin hydrochloridetablets is higher if you:
  • Are over 60 years of age
  • Are taking steroids (corticosteroids)
  • Have had a kidney, heart or lung transplant

Tendon problems can happen in people who do not have the above risk factors when they take moxifloxacin hydrochloride tablets.

• Other reasons that can increase your risk of tendon problems can include:
  • Physical activity or exercise
  • Kidney failure
  • Tendon problems in the past, such as in people with rheumatoid arthritis (RA).

• Call your healthcare provider right away at the first sign of tendon pain, swelling or inflammation. Stop taking moxifloxacin hydrochloride tablets until tendinitis or tendon rupture has been ruled out by your healthcare provider. Avoid exercise and using the affected area. The most common area of pain and swelling is in the Achilles tendon at the back of your ankle. This can also happen with other tendons.
• Talk to your healthcare provider about the risk of tendon rupture with continued use of moxifloxacin hydrochloride tablets. You may need a different antibiotic that is not a fluoroquinolone to treat your infection.
• Tendon rupture can happen while you are taking or after you have finished taking moxifloxacin hydrochloride tablets. Tendon ruptures can happen within hours or days after taking moxifloxacin hydrochloride tablets and have happened up to several months after patients have finished taking their fluoroquinolone.
• Stop taking moxifloxacin hydrochloride tablets immediately and get medical help right away if you get any of the following signs or symptoms of a tendon rupture:
  •  Hear or feel a snap or pop in a tendon area  
  • Bruising right after an injury in a tendon area  
  • Unable to move the affected area or bear weight.

2.Changes in sensation and possible nerve damage (Peripheral Neuropathy). Damage to the nerves in arms, hands, legs, or feet can happen in people who take fluoroquinolones, including moxifloxacin hydrochloride tablets. Stop taking moxifloxacin hydrochloride tablets immediately and talk to your healthcare provider right away if you get any of the following symptoms of peripheral neuropathy in your arms, hands, legs, or feet:

• pain

• burning

• tingling

• numbness

• weakness  

Moxifloxacin hydrochloride tablets may need to be stopped to prevent permanent nerve damage.  

3. Central Nervous System (CNS) effects. Seizures have been reported in people who take fluoroquinolone antibacterial medicines, including moxifloxacin hydrochloride tablets. Tell your healthcare provider if you have a history of seizures before you start taking moxifloxacin hydrochloride tablets. CNS side effects may happen as soon as after taking the first dose of moxifloxacin hydrochloride tablets. Stop taking moxifloxacin hydrochloride tablets immediately and talk to your healthcare provider right away if you get any of these side effects, or other changes in mood or behavior:

• seizures

• hear voices, see things, or sense things that are not there (hallucinations)

• feel restless

• tremors

• feel anxious or nervous

• confusion

• depression

• trouble sleeping

• nightmares

• feel lightheaded or dizzy

• feel more suspicious (paranoia)

• suicidal thoughts or acts

• headaches that will not go away, with or without blurred vision.

4. Worsening of myasthenia gravis (a disease which causes muscle weakness). Fluoroquinolones like moxifloxacin hydrochloride tablets may cause worsening of myasthenia gravis symptoms, including muscle weakness and breathing problems. Tell your healthcare provider right away if you have a history of myasthenia gravis before you start taking moxifloxacin hydrochloride tablets. Call your healthcare provider right away if you have any worsening muscle weakness or breathing problems.

What are moxifloxacin hydrochloride tablets?

Moxifloxacin hydrochloride tablets are a fluoroquinolone antibiotic medicine used to treat certain types of infections caused by certain germs called bacteria in adults 18 years or older. These bacterial infections include:

• Community Acquired Pneumonia

• Uncomplicated Skin and Skin Structure Infections

• Complicated Skin and Skin Structure Infections

• Complicated Intra-Abdominal Infections

• Plague

• Acute Bacterial Sinusitis

• Acute Bacterial Exacerbation of Chronic Bronchitis  

Moxifloxacin hydrochloride tablets should not be used in patients with acute bacterial sinusitis or acute bacterial exacerbation of chronic bronchitis if there are other treatment options available.

Studies of moxifloxacin for use in the treatment of plague were done in animals only, because plague could not be studied in people.

It is not known if moxifloxacin hydrochloride tablets are safe and works in people under 18 years of age. Children have a higher chance of getting bone, joint, and tendon (musculoskeletal) problems while taking fluoroquinolone antibiotic medicines.

Sometimes infections are caused by viruses rather than by bacteria. Examples include viral infections in the sinuses and lungs, such as the common cold or flu. Antibiotics, including moxifloxacin hydrochloride tablets, do not kill viruses.

Call your healthcare provider if you think your condition is not getting better while you are taking moxifloxacin hydrochloride tablets.

Do not take moxifloxacin hydrochloride tablets if you have ever had a severe allergic reaction to an antibiotic known as a fluoroquinolone, or if you are allergic to any of the ingredients in moxifloxacin hydrochloride tablets. Ask your healthcare provider if you are not sure. See the list of ingredients in moxifloxacin hydrochloride tablets at the end of this Medication Guide.
