Baxdela

Generic name: delafloxacin

What is Baxdela?

Baxdela is a fluoroquinolone antibacterial medicine used to treat certain types of infections caused by certain germs called bacteria in adults 18 years or older. These bacterial infections include:

• skin infections
• community-acquired bacterial pneumonia

It is not known if Baxdela is safe and effective in people under 18 years of age, and use in people under 18 years of age is not recommended. Children younger than 18 years of age may have a higher chance of getting bone, joint, and tendon (musculoskeletal) problems while taking fluoroquinolone antibacterial 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. Antibacterial medicines, including Baxdela, do not kill viruses. Call your healthcare provider if you think your condition is not getting better while you are taking Baxdela.

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

• Tendon problems can happen in people of all ages who take Baxdela. 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 Baxdela 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 Baxdela. 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 Baxdela immediately and call your healthcare provider right away at the first sign of tendon pain, swelling or inflammation. Stop taking Baxdela 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 Baxdela. You may need a different antibacterial that is not a fluoroquinolone to treat your infection.
• Tendon rupture can happen while you are taking or after you have finished taking fluoroquinolone antibacterial medicines like Baxdela. Tendon ruptures can happen within hours or days of taking a fluoroquinolone and have happened up to several months after patients have finished taking their fluoroquinolone.
• Stop taking Baxdela 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

• numbness
• weakness

Baxdela 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.
