Generic Name: Gemifloxacin (JEM-i-FLOX-a-sin)Brand Name: Factive

Gemifloxacin is associated with an increased risk of tendon problems. These include pain, swelling, inflammation, and possible breakage of tendons. The risk of tendon problems is greater in patients who are over 60 years old, take corticosteroids (eg, prednisone), or have received kidney, heart, or lung transplants. The Achilles tendon in the back of the foot/ankle area is most often affected. However, problems may also occur in other tendons (eg, in the shoulder, arm, or hand). Problems may occur while you take Gemifloxacin or up to several months after you stop taking it.

Signs of tendon problems may include pain, soreness, redness, or swelling of a tendon or joint; bruising right after an injury in a tendon area; hearing or feeling a snap or pop in a joint or tendon area; or inability to move or bear weight on a joint or tendon area. Tell your doctor right away if you experience any of these symptoms while you take Gemifloxacin or within several months after you stop it.
