What is the most important information I should know about levofloxacin tablets?
Levofloxacin tablets, 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 tablets, get medical help right away. Talk
with your healthcare provider about whether you should continue to take levofloxacin tablets.
1. Tendon rupture or swelling of the tendon (tendinitis).
- Tendon problems can happen in people of all ages who take levofloxacin tablets. Tendons are tough cords of tissue that connect muscles to bones.
Some tendon problems 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 levofloxacin tablets are 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 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 levofloxacin
tablets until tendinitis or tendon rupture has been ruled out by your healthcare provider. Avoid exercise and using the affected
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. Talk to your healthcare provider about the risk of tendon rupture with continued use of levofloxacin tablets. You
may need a different antibiotic that is not a fluoroquinolone to treat your infection.
2. Worsening of myasthenia gravis (a problem that causes muscle weakness).
- Tendon rupture can happen while you are taking or after you have finished taking levofloxacin tablets. Tendon ruptures have
happened up to several months after people have finished taking their fluoroquinolone.
- 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
Fluoroquinolones like levofloxacin tablets may cause worsening of myasthenia gravis symptoms, including muscle weakness and
breathing problems. Call your healthcare provider right away if you have any worsening muscle weakness or breathing problems.
What are levofloxacin tablets?
- See “What are the possible side effects of levofloxacin tablets?”
Levofloxacin tablets are a fluoroquinolone antibiotic medicine used in adults age 18 years or older to treat certain infections
caused by certain germs called bacteria. These bacterial infections include:
- nosocomial pneumonia
- community-acquired pneumonia
- acute sinus infection
- acute worsening of chronic bronchitis
- skin infections, complicated and uncomplicated
- chronic prostate infection
- urinary tract infections, complicated and uncomplicated
- acute kidney infection (pyelonephritis)
- inhalational anthrax
Studies of levofloxacin tablets for use in the treatment of plague and anthrax were done in animals only, because plague and
anthrax could not be studied in people.
Levofloxacin tablets are also used to treat children who are 6 months of age or older and may have breathed in anthrax germs,
have plague, or been exposed to plague germs.
It is not known if levofloxacin tablets are safe and effective in children under 6 months of age.
The safety and effectiveness in children treated with levofloxacin tablets for more than 14 days is not known. Who should not take levofloxacin tablets? Do not take levofloxacin tablets
if you have ever had a severe allergic reaction to an antibiotic known as a fluoroquinolone, or if you are allergic to levofloxacin
or any of the ingredients in levofloxacin tablets. See the end of this leaflet for a complete list of ingredients in levofloxacin
tablets. What should I tell my healthcare provider before taking levofloxacin tablets? Before you take levofloxacin tablets, tell your healthcare provider if you:
Tell your healthcare provider about all the medicines you take,
- have tendon problems
- have a problem that causes muscle weakness (myasthenia gravis)
- have central nervous system problems such as seizures (epilepsy)
- have nerve problems
- have or anyone in your family has an irregular heartbeat, especially a condition called “QT prolongation”
- have low blood potassium (hypokalemia)

including prescription and non-prescription medicines, vitamins, and herbal supplements.
Levofloxacin tablets and other medicines can affect each other causing side effects.
Especially tell your healthcare provider if you take:
- a steroid medicine
