  "spl_medguide": "MEDICATION GUIDE Levofloxacin (lee\" voe flox' a sin) Tablets, USP What is the most important information I should know about levofloxacin tablets? Levofloxacin, a fluoroquinolone antibiotic, can cause serious side effects. Some of these serious side effects can happen at the same time and could result in death. If you have any of the following serious side effects while you take levofloxacin tablets, you should stop taking levofloxacin tablets immediately and get medical help right away. 1. Tendon rupture or swelling of the tendon (tendinitis). \u2022 Tendon problems can happen in people of all ages who take levofloxacin tablets. Tendons are tough cords of tissue that connect muscles to bones. Some tendon problems include pain, swelling, tears, and swelling of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites. \u2022 The risk of getting tendon problems while you take levofloxacin tablets is higher if you: \u25cb are over 60 years of age \u25cb are taking steroids (corticosteroids) \u25cb have had a kidney, heart or lung transplant. \u2022 Tendon problems can happen in people who do not have the above risk factors when they take levofloxacin tablets. \u2022 Other reasons that c...",
  "clinical_studies": "14.1 Nosocomial Pneumonia Adult patients with clinically and radiologically documented nosocomial pneumonia were enrolled in a multicenter, randomized, open-label study comparing intravenous levofloxacin (750 mg once daily) followed by oral levofloxacin (750 mg once daily) for a total of 7 to 15 days to intravenous imipenem/cilastatin (500 to 1,000 mg every 6 to 8 hours daily) followed by oral ciprofloxacin (750 mg every 12 hours daily) for a total of 7 to 15 days. Levofloxacin-treated patients received an average of 7 days of intravenous therapy (range: 1 to 16 days); comparator-treated patients received an average of 8 days of intravenous therapy (range: 1 to 19 days). Overall, in the clinically and microbiologically evaluable population, adjunctive therapy was empirically initiated at study entry in 56 of 93 (60.2%) patients in the levofloxacin arm and 53 of 94 (56.4%) patients in the comparator arm. The average duration of adjunctive therapy was 7 days in the levofloxacin arm and 7 days in the comparator.
