Read this Medication Guide before you start taking Levofloxacin Injection and each time you get a refill. There may be new information. 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 Levofloxacin Injection?

Levofloxacin, a fluoroquinolone antibiotic, can cause serious side effects. Some of these serious side effects could result in death.

If you have any of the following serious side effects while you take Levofloxacin Injection, you should stop taking Levofloxacin Injection immediately and get medical help right away.

  1. Tendon rupture or swelling of the tendon (tendinitis).
    • Tendon problems can happen in people of all ages who take Levofloxacin Injection. Tendons are tough cords of tissue that connect muscle to bones.
      Some tendon problems include pain, swelling, tears, and swelling of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites.
    • The risk of getting tendon problems while you take levofloxacin 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 levofloxacin.
    • 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)
    • Stop taking Levofloxacin Injection immediately and get medical help right away at the first sign of tendon pain, swelling or inflammation. Avoid exercise and using the affected area.
      The most common area of pain and swelling is the Achilles tendon at the back of your ankle. This can also happen with other tendons. 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 levofloxacin. Tendon ruptures can happen within hours or days of taking levofloxacin and have happened up to several months after people have finished taking their fluoroquinolone.
    • Stop taking Levofloxacin Injection 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 Levofloxacin Injection. Stop taking Levofloxacin Injection 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

    The nerve damage may be permanent.

  3. Central Nervous System (CNS) effects. Seizures have been reported in people who take fluoroquinolone antibacterial medicines, including Levofloxacin Injection. Tell your healthcare provider if you have a history of seizures before you start taking Levofloxacin Injection. CNS side effects may happen as soon as after taking the first dose of Levofloxacin Injection. Stop taking Levofloxacin Injection 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 problem that causes muscle weakness).
    Fluoroquinolones like levofloxacin may cause worsening of myasthenia gravis symptoms, including muscle weakness and breathing problems. Tell your healthcare provider if you have a history of myasthenia gravis before you start taking Levofloxacin Injection. Call your healthcare provider right away if you have any worsening muscle weakness or breathing problems.
