What is the most important information I should know about ciprofloxacin tablets?

If you get any of the following serious side effects while you take ciprofloxacin tablets, you should stop taking ciprofloxacin tablets 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 ciprofloxacin tablets. Tendons are tough cords of tissue that connect muscles to bones. Symptoms of tendon problems may include:
  • pain
  • swelling
  • tears and swelling of the tendons including the back of the ankle (Achilles), shoulder, hand, thumb, or other tendon sites.
• The risk of getting tendon problems while you take ciprofloxacin tablets 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 ciprofloxacin 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).
• Stop taking ciprofloxacin tablets immediately and get medical help right away at the first sign of tendon pain, swelling or inflammation. 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.
• Tendon rupture can happen while you are taking or after you have finished taking ciprofloxacin tablets. Tendon ruptures can happen within hours or days of taking ciprofloxacin tablets and have happened up to several months after people have finished taking their fluoroquinolone.
• Stop taking ciprofloxacin tablets 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

The tendon problems may be permanent.

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 ciprofloxacin tablets. Stop taking ciprofloxacin tablets 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
• numbness
• burning
• weakness
• tingling

Ciprofloxacin tablets may need to be stopped to prevent permanent nerve damage.

3. Central Nervous System (CNS) effects. Mental health problems and seizures have been reported in people who take fluoroquinolone antibacterial medicines, including ciprofloxacin tablets. Tell your healthcare provider if you have a history of seizures before you start taking ciprofloxacin tablets. CNS side effects may happen as soon as after taking the first dose of ciprofloxacin tablets. Stop taking ciprofloxacin tablets 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

These changes may be permanent.
