What is the most important information I should know about ciprofloxacin hydrochloride tablets? Ciprofloxacin hydrochloride tablets belong to a class of antibiotics called fluoroquinolones. Ciprofloxacin hydrochloride tablets can cause side effects that may be serious or even cause death. If you get any of the following serious side effects, get medical help right away. Talk with your healthcare provider about whether you should continue to take ciprofloxacin hydrochloride tablets.

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 ciprofloxacin hydrochloride tablets. 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 provider right away at the first sign of tendon pain, swelling or inflammation. Stop taking ciprofloxacin hydrochloride tablets 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 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 ciprofloxacin hydrochloride tablets. 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 ciprofloxacin hydrochloride tablets. 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

• unable to move the affected area or bear weight

• See the sectionWhat are the possible side effects of ciprofloxacin hydrochloride tablets?for more information about side effects.

• What are ciprofloxacin hydrochloride tablets?

• Ciprofloxacin hydrochloride tablets are fluoroquinolone antibiotic medicine used to treat certain infections caused by certain germs called bacteria.

Children less than 18 years of age have a higher chance of getting bone, joint, or tendon (musculoskeletal) problems such as pain or swelling while taking ciprofloxacin hydrochloride tablets. Ciprofloxacin hydrochloride tablets should not be used as the first choice of antibiotic medicine in children under 18 years of age. Ciprofloxacin hydrochloride tablets should not be used in children under 18 years old, except to treat specific serious infections, such as complicated urinary tract infections and to prevent anthrax disease after breathing the anthrax bacteria germ (inhalational exposure).

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. Antibiotics, including ciprofloxacin hydrochloride tablets, do not kill viruses.

Call your healthcare provider if you think your condition is not getting better while you are taking ciprofloxacin hydrochloride tablets.
