- WHAT IS LEVAQUIN®?
- HOW EFFECTIVE IS LEVAQUIN®?
- WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT LEVAQUIN®?
- Tendon Rupture or Swelling of the Tendon (tendinitis)
- Tendon rupture or swelling of the tendon (tendinitis)
- Tendons are tough cords of tissue that connect muscles to bones
- Pain, swelling, tears, and inflammation of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites can happen in people of all ages who take fluoroquinolone antibiotics, including LEVAQUIN®. The risk of getting tendon problems is higher if you:
- Are over 60 years of age
- Are taking steroids (corticosteroids)
- Have had a kidney, heart, or lung transplant
- Swelling of the tendon (tendinitis) and tendon rupture (breakage) have also happened in patients who take fluoroquinolones who do not have the above risk factors
- Other reasons for tendon ruptures can include:
- Physical activity or exercise
- Kidney failure
- Tendon problems in the past, such as in people with rheumatoid arthritis (RA)
- Call your healthcare professional right away at the first sign of tendon pain, swelling, or inflammation. Stop taking LEVAQUIN® until tendinitis or tendon rupture has been ruled out by your healthcare professional. 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. Talk to your healthcare professional about the risk of tendon rupture with continued use of LEVAQUIN®. 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 LEVAQUIN®. Tendon ruptures have happened up to several months after patients 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

Fluoroquinolones, including LEVAQUIN®, are associated with an increased risk of tendinitis and tendon rupture in all ages. This risk is further increased in older patients usually over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart, or lung transplants. Call your healthcare professional right away at the first sign of tendon pain, swelling, or inflammation. You should stop taking LEVAQUIN® until tendinitis or tendon rupture have been ruled out, and avoid exercise and using the affected area.
Liver damage (hepatotoxicity) can happen in people who take LEVAQUIN®. Call your healthcare professional right away if you have unexplained symptoms such as:
Allergic reactions can happen in people taking fluoroquinolones, including LEVAQUIN®, even after only one dose. Stop taking LEVAQUIN® and get emergency medical help right away if you get any of the following symptoms of a severe allergic reaction:
Skin rash may happen in people taking LEVAQUIN®, even after only one dose. Stop taking LEVAQUIN® at the first sign of a skin rash and call your healthcare professional. Skin rash may be a sign of a more serious reaction to LEVAQUIN®.
Pseudomembranous colitis can happen with most antibiotics, including LEVAQUIN®. Call your healthcare professional right away if you get watery diarrhea, diarrhea that does not go away, or bloody stools. You may have stomach cramps and a fever. Pseudomembranous colitis can happen 2 or more months after you have finished your antibiotic.

LEVAQUIN® may need to be stopped to prevent permanent nerve damage.
Tell your healthcare professional right away if you have a change in your heart beat (a fast or irregular heartbeat), or if you faint. LEVAQUIN® may cause a rare heart problem known as prolongation of the QT interval. This condition can cause an abnormal heartbeat and can be very dangerous. The chances of this happening are higher in people:
People who take LEVAQUIN® and other fluoroquinolone medicines with oral anti-diabetes medicines or with insulin can get low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia). Follow your healthcare professional's instructions for how often to check your blood sugar. If you have diabetes and you get low blood sugar while taking LEVAQUINreg;, stop taking LEVAQUIN® and call your healthcare professional right away. Your antibiotic medicine may need to be changed.
Increased chance of problems with joints and tissues around joints in children. Tell your child's healthcare professional if your child has any joint problems during or after treatment with LEVAQUIN®.
Additional Information
Different antibiotics work in different ways to kill bacteria. LEVAQUIN® is a type of antibiotic called a fluoroquinolone. Fluoroquinolone antibiotics are "bactericidal," which means they kill the bacteria causing the infection. Other types of antibiotics stop bacteria from growing. Fluoroquinolones are concentration-dependent drugs, meaning they kill bacteria more efficiently when a higher amount of medicine reaches the area of infection. Your healthcare professional will prescribe the best antibiotic strength and duration for your infection.
Antibiotics—also known as antibacterial or antimicrobial drugs—fight bacterial infections by killing bacteria, or by slowing or stopping bacterial growth. While antibiotics were first used in the 1940's, they continue to transform medical care today by dramatically reducing illness and death from infectious diseases.

There are many types of bacteria, which are tiny living organisms. Most are harmless and some are even helpful. But some bacteria can cause diseases in humans. Antibiotics fight bacterial infections by slowing or stopping the growth of bacteria.
While antibiotics are an effective way to treat bacterial infections, improper use can lead to antibiotic resistance. Resistance happens because bacteria can change, or "mutate," in ways that makes it harder for antibiotics to work against them.

Fluoroquinolones are a type of antibiotic used to treat bacterial infections. They are "bactericidal," which means they actually kill the bacteria that are causing an infection.

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. Only your healthcare professional can tell if your infection is viral or bacterial. Antibiotics, including LEVAQUIN®, do not kill viruses.

Only your healthcare professional can tell for sure if you have a GU infection. But common symptoms include
Only your healthcare professional can tell for sure if you have a skin or skin structure infection. The skin is a barrier against many infections. But bacteria can sometimes take hold at or near the skin's surface, prompting an uncomplicated skin or skin structure infection. Bacteria that infect the deeper soft tissues can cause a complicated skin or skin structure infection.
There are 2 types of germs that cause most infections: viruses and bacteria.
And while the symptoms are often similar, it is important to know that antibiotics only work for infections caused by bacteria. If you have a viral infection, taking an antibiotic will not help--and can even be harmful by contributing to antibiotic resistance. How do you know whether your infection is viral or bacterial? Only your healthcare professional can determine if you have a viral or bacterial infection.
LEVAQUIN® should be taken once per day, ideally at the same time each day. Do not take more than the prescribed dose of LEVAQUIN® even if you missed a dose by mistake—you should not take a double dose. Your healthcare professional will determine the formulation (tablet or oral solution) and the number of days you should take LEVAQUIN®.
Never take more than the prescribed dose of LEVAQUIN®, even if you missed a dose by mistake. You should not take more than one dose in one day. LEVAQUIN® should be taken once per day, ideally at the same time each day.
