Lungs are a pair of breathing organs located within the chest. Their function is to remove carbon dioxide from the air and bring oxygen to the blood. Pneumonia is a serious infection that affects the lungs. It is caused by viruses, bacteria, fungi, or the parasites, but most commonly pneumonia is caused by bacteria and viruses.

FACTIVE (Gemifloxacin Mesylate) is an antibiotic that is highly active against many different bacteria, including those that are most likely to contribute to bacterial infections. Factive rapidly travels to the site of infection, and provides fast clinical recovery. FACTIVE has a well-characterized safety profile, which has been used to treat over 5 million patients worldwide.

What is FACTIVE What does FACTIVE do How FACTIVE works When I should take FACTIVE


Because of its relatively long half-life, FACTIVE is amenable to once-daily dosing so it is a convenient drug that will aid compliance with antibiotic treatment. FACTIVE is also effective in shorter courses than any other antibiotic due to its rapid bactericidal action. For more complete information about FACTIVE, request full prescribing information from your healthcare professional or pharmacist.

Common Questions


Important Safety Information


FACTIVE is contraindicated in patients with a history of hypersensitivity to gemifloxacin, fluoroquinolone antibiotic agents, or any of the product components. Serious hypersensitivity and/or anaphylactic reactions have been reported in patients receiving fluoroquinolone therapy, including FACTIVE. Hypersensitivity reactions reported in patients receiving fluoroquinolone therapy have occasionally been fatal. These reactions may include serious, sometimes fatal skin reactions such as toxic epidermal necrolysis or Stevens-Johnson Syndrome; effects on the liver, including hepatitis, jaundice, and acute hepatic necrosis or failure; renal toxicities including interstitial nephritis and/or acute renal insufficiency or failure; and hematologic effects, including agranulocytosis, thrombocytopenia, and other hematologic abnormalities. These reactions may occur following the first dose or multiple doses. FACTIVE should be discontinued immediately at the first sign of an immediate type I hypersensitivity skin rash or any other manifestation of hypersensitivity reaction.

Fluoroquinolones, including FACTIVE, are associated with an increased risk of tendinitis and tendon rupture in all ages. This risk is further increased in older patients usually over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart, or lung transplants. Call your healthcare professional right away at the first sign of tendon pain, swelling, or inflammation. You should stop taking FACTIVE until tendinitis or tendon rupture have been ruled out, and avoid exercise and using the affected area.

Fluoroquinolones may prolong the QT interval in some patients. FACTIVE should be avoided in patients with a history of prolongation of the QTc interval, patients with uncorrected electrolyte disorders (hypokalemia or hypomagnesemia), and patients receiving Class IA or Class III antiarrhythmic agents.

Rare cases of peripheral neuropathy have been reported in patients receiving quinolones.

In clinical studies with FACTIVE, central nervous system (CNS) effects have been reported infrequently. As with other fluoroquinolones, FACTIVE should be used with caution in patients with known or suspected CNS diseases. If CNS reactions occur, FACTIVE should be discontinued and appropriate measures instituted.

Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibiotic agents, including FACTIVE. If diarrhea occurs, evaluate for CDAD and treat appropriately.

In clinical trials, rash occurred more often with FACTIVE than therapy with comparator agents (2.8% vs. 0.6%). Increasing incidence of rash was associated with younger age (especially below 40), female gender, use of hormone replacement therapy, and longer duration of therapy.

Moderate to severe photosensitivity/phototoxicity reactions can be associated with the use of quinolones after sun or UV light exposure. Excessive exposure to the sun or UV light should be avoided.

Magnesium- and/or aluminum-containing antacids, products containing ferrous sulfate (iron), multivitamin preparations containing zinc or other cations, or Videx® (didanosine) chewable/buffered tablets or the pediatric powder for oral solution should not be taken within 3 hours before or 2 hours after FACTIVE. Sucralfate should not be taken within 2 hours of FACTIVE.

In clinical trials, the most common adverse drug reactions (≥2%) were diarrhea, rash, nausea, headache, abdominal pain, vomiting, and dizziness.
