    LEVAQUIN Overdose

    According to animal studies, LEVAQUIN is toxic in high doses, causing a number of muscular and nervous system symptoms, such as tremors, convulsions, and loss of control of bodily movements.

    Call your local poison control center or visit the nearest emergency hospital room if you've overdosed on LEVAQUIN to have your stomach emptied.

    Call 9-1-1 if you think someone has overdosed and has collapsed or isn't breathing.

    Missed Dose of LEVAQUIN

    Take the missed dose as soon as you remember it, unless it's almost time for next dose.

    Warnings and Precautions

    The risk of tendonitis and tendon ruptures is greater for people over 60 years old, people taking corticosteroid drugs, and people with kidney, heart, or lung transplants.

    Physical activity or exercise, kidney failure, and having previous tendon problems, such as rheumatoid arthritis, can also increase your risk of tendon issues while taking LEVAQUIN.

    You should not take LEVAQUIN if you have a known sensitivity or allergy to levofloxacin and other quinolones (the family of antibiotics that encompasses fluoroquinolones).

    You should also avoid the drug if you have the neuromuscular disease myasthenia gravis, as the drug could worsen your muscle weakness.

    Some people experience other serious and sometimes life-threatening reactions from taking LEVAQUIN, such as:

    • Dangerous skin disorders, including toxic epidermal necrolysis and Stevens- Johnson Syndrome
    • Blood vessel inflammation, joint pain, and muscle pain
    • Allergic pneumonitis, an inflammation of the walls of the lung's air sacs
    • Interstitial nephritis (a kidney disorder) and kidney failure
    • Hepatitis (liver inflammation), jaundice (yellowing of the skin and eyes), liver cell death, and liver failure
    • Blood-related issues, including deficiencies in red blood cells or white blood cells

    Pregnancy and LEVAQUIN

    It's unknown if LEVAQUIN can harm a developing fetus because no adequate and well-controlled studies have been carried out in pregnant women.

    However, the drug's antimicrobial benefits to the mother may outweigh the potential risks to her unborn child.

    Levofloxacin is presumed to be present in breast milk, and the drug has the potential to cause serious side effects in infants.

    Breastfeeding mothers taking LEVAQUIN should either discontinue the drug or stop breastfeeding.
