It is not known if Factive is safe and effective in children under 18 years of age. Children have a higher chance of getting bone, joint, or tendon (musculoskeletal) problems such as pain or swelling while taking fluoroquinolone antibiotic medicines.
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. Antibiotic medicines including Factive do not kill viruses.
Call your healthcare provider if you think your condition is not getting better while you are taking Factive.
FACTIVE (gemifloxacin mesylate) is a synthetic broad-spectrum antibacterial agent for oral administration. Gemifloxacin, a compound related to the fluoroquinolone class of antibiotics, is available as the mesylate salt in the sesquihydrate form. Chemically, gemifloxacin is (R,S)-7-[(4Z)-3-(aminomethyl)-4-(methoxyimino)-1-pyrrolidinyl]-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid.
The mesylate salt is a white to light brown solid with a molecular weight of 485.49. Gemifloxacin is considered freely soluble at neutral pH (350 μg/mL at 37ºC, pH 7.0). Its empirical formula is C18H20FN5O4•CH4O3S and its chemical structure is:
Each white to off-white, oval, film-coated FACTIVE tablet has breaklines and GE 320 debossed on both faces and contains gemifloxacin mesylate equivalent to 320 mg gemifloxacin. The inactive ingredients are crospovidone, hydroxypropyl methylcellulose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, povidone, and titanium dioxide.
What is the most important information I should know about Factive?
Factive, a fluoroquinolone antibiotic medicine, can cause serious side effects. Some of these serious side effects can happen at the same time and could result in death.
If you get any of the following serious side effects while you are taking Factive, you should stop taking Factive 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 Factive. Tendons are tough cords of tissue that connect muscles to bones. Symptoms of tendon problems may include: pain, swelling, tears, and inflammation of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites.
- The risk of getting tendon problems while you take Factive 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 Factive.
- 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 Factive immediately and get medical help right away at the first sign of tendon pain, swelling or inflammation. Stop taking Factive 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 Factive. You may need a different antibiotic medicine that is not a fluoroquinolone to treat your infection.
- Tendon rupture can happen while you are taking or after you have finished taking Factive. Tendon ruptures can happen within hours or days of taking Factive and 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 put weight on the affected area
2. Changes in sensation and possible nerve damage (Peripheral Neuropathy). Damage to the nerves in arms, hands, legs, or feet can happen in people taking fluoroquinolones, including Factive. Stop taking Factive and call your healthcare provider right away if you get any of the following symptoms of peripheral neuropathy in your arms, hands, legs, or feet:
The nerve damage may be permanent.
3. Central Nervous System (CNS) effects. Seizures have been reported in people who take fluoroquinolone antibiotic medicines, including Factive. Tell your healthcare provider if you have a history of seizures. Ask your healthcare provider whether taking Factive will change your risk of having a seizure. CNS side effects may happen as soon as after taking the first dose of Factive. Call your healthcare provider right away if you get any of these side effects, or other changes in mood or behavior:
- feel dizzy
- hear voices, see things, or sense things that are not there (hallucinations)
- feel restless
- feel anxious or nervous
- trouble sleeping
- feel more suspicious (paranoia)
- suicidal thoughts or acts
- feeling lightheaded
4. Worsening of myasthenia gravis (a disease which causes muscle weakness). Fluoroquinolones like Factive may cause worsening of myasthenia gravis symptoms, including muscle weakness and breathing problems. Tell your healthcare provider if you have a history of myasthenia gravis before you start taking Factive. Call your healthcare provider right away if you have any worsening muscle weakness or breathing problems.
See the section “What are the possible side effects of Factive?” for more information about side effects.

Especially tell your healthcare provider if you take:
- a Non-Steroidal Anti-Inflammatory Drug (NSAID). Many common medicines for pain relief are NSAIDs. Taking an NSAID while you take Factive or other fluoroquinolones may increase your risk of CNS effects and seizures. See “What is the most important information I should know about Factive?”

- a water pill (diuretic).
- probenecid (Probalan, Col-Probenecid).
- a steroid medicine. Corticosteroids taken by mouth or by injection may increase the chance of tendon injury. See “What is the most important information I should know about Factive?”
Certain medicines may keep Factive from working correctly. Take Factive at least 3 hours before or 2 hours after taking these products:
- an antacid, multivitamin, or other product that contains magnesium, aluminum, iron, or zinc
- sucralfate (Carafate)
- didanosine (Videx, Videx EC)
Ask your healthcare provider if you are not sure if any of your medicines are listed above.

What are the possible side effects of Factive?
Factive may cause serious side effects, including:
- See “What is the most important information I should know about Factive?”

- Skin rash may also happen in people taking Factive. Stop taking Factive at the first sign of a skin rash and call your healthcare provider. Skin rash may be a sign of a more serious reaction to Factive. Rash happens more often with Factive in:
- women, especially women who take hormone replacement therapy
- people under 40 years of age
- people who take Factive for longer than 5 days
- Clostridium difficile-associated diarrhea (CDAD). CDAD is an infection of your intestines (bowels) that can happen with many antibiotic medicines like Factive and may cause mild diarrhea to life-threatening swelling of your intestines (colitis). Call your healthcare provider right away if you get stomach cramps, fever, watery diarrhea, diarrhea that does not go away, or bloody stools.

The chances of this happening are higher in people:
- who are elderly
- with a family history of prolonged QT interval
- with low blood potassium (hypokalemia) or low magnesium (hypomagnesemia)
- who take certain medicines to control heart rhythm (antiarrhythmics)
- Changes in blood sugar
