Serious side effects have been reported including:
- tendon problems. This can happen in people of all ages who take gemifloxacin. Tell your healthcare provider right away if you have the following symptoms of tendon problems:
- 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
- worsening of myasthenia gravis (a disease which causes muscle weakness). Gemifloxacin may cause worsening of myasthenia gravis symptoms, including muscle weakness and breathing problems. Call your healthcare provider right away if you have any worsening muscle weakness or breathing problems.
- peripheral neuropathy. This is a condition of nerve damage that may occur. Tell your healthcare provider right away if you experience pain, burning, tingling, numbness, weakness, or a change in sensation to light touch, pain or temperature. These symptoms can occur early in treatment and may be permanent. It may be necessary to stop gemifloxacin, but do not do so without first talking with your health care professional.
- serious heart rhythm changes (QTc prolongation and torsades de pointes). Tell your healthcare provider right away if you have a change in your heartbeat (a fast or irregular heartbeat), or if you faint. Gemifloxacin may cause a rare heart problem known as prolongation of the QT interval. This condition can cause an abnormal heartbeat and can be very dangerous. 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)
- who take certain medicines to control heart rhythm (antiarrhythmics).
- intestine infection (pseudomembranous colitis). Pseudomembranous colitis can happen with most antibiotics, including gemifloxacin. Call your healthcare provider right away if you get watery diarrhea, diarrhea that does not go away, or bloody stools. You may have stomach cramps and a fever. Pseudomembranous colitis can happen 2 or more months after you have finished your antibiotic.
- sensitivity to sunlight. Avoid sunlamps, tanning beds, and try to limit your time in the sun. Gemifloxacin can make your skin sensitive to the sun (photosensitivity) and the light from sunlamps and tanning beds. You could get severe sunburn, blisters or swelling of your skin. If you get any of these symptoms while taking gemifloxacin, call your healthcare provider right away. You should use sunscreen and wear a hat and clothes that cover your skin if you have to be in sunlight.
- central nervous system effects. Seizures have been reported in people who take fluoroquinolone antibiotics, including gemifloxacin. Tell your healthcare provider if you have a history of seizures. Ask your healthcare provider whether taking gemifloxacin will change your risk of having a seizure. Central Nervous System (CNS) side effects may occur as soon as after taking the first dose of gemifloxacin. Talk to 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
- serious allergic reactions. Allergic reactions can happen in people taking fluoroquinolones, including gemifloxacin, even after only one dose. Stop taking gemifloxacin and get emergency medical help right away if you get any of the following symptoms of a severe allergic reaction:
- trouble breathing or swallowing
- swelling of the lips, tongue, face
- throat tightness, hoarseness
- rapid heartbeat
- yellowing of the skin or eyes. Stop taking gemifloxacin and call your healthcare provider right away if you get yellowing of your skin or white part of your eyes, or if you have dark urine. These can be signs of a serious reaction to gemifloxacin (a liver problem).
- skin rash. Skin rash may happen in people taking gemifloxacin. Stop taking gemifloxacin 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 gemifloxacin. Rash happens more often with gemifloxacin in:
- women, especially women who take hormone replacement therapy
- people under 40 years of age
- people who take gemifloxacin for longer than 5 days.

Gemifloxacin and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
Gemifloxacin falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.
Gemifloxacin and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
Gemifloxacin has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from gemifloxacin, a choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.
- Take gemifloxacin exactly as prescribed by your healthcare provider.
- Take gemifloxacin at about the same time each day.
- Gemifloxacin tablets should be swallowed.
- Gemifloxacin can be taken with or without food.
- Gemifloxacin should not be taken with dairy products (like milk or yogurt) or calcium-fortified juices alone, but may be taken with a meal that contains these products.
- Drink plenty of fluids while taking gemifloxacin.
- Do not skip any doses, or stop taking gemifloxacin even if you begin to feel better, until you finish your prescribed treatment, unless:
- You have tendon effects
- You have a serious allergic reaction, or your healthcare provider tells you to stop.
- This will help make sure that all of the bacteria are killed and lower the chance that the bacteria will become resistant to gemifloxacin. If this happens, gemifloxacin and other antibiotic medicines may not work in the future.
- If you miss a dose of gemifloxacin, take it as soon as you remember. Do not take more than 1 dose of gemifloxacin in one day.
- If you take too much, call your healthcare provider or get medical help immediately.
Take gemifloxacin exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.
The gemifloxacin dose your doctor recommends will be based on the following:
- the condition being treated
- other medical conditions you have
- other medications you are taking
- how you respond to this medication
The recommended dose range of gemifloxacin is 160 to 320 mg once daily.
If you take too much gemifloxacin, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.
- Store between 15º-30ºC (59º-86ºF).
- Protect from light.
- Keep this and all medications out of the reach of children.
Gemifloxacin FDA Warning
Fluoroquinolones, including gemifloxacin, 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.
Fluoroquinolones, including gemifloxacin, may exacerbate muscle weakness in persons with myasthenia gravis. Avoid gemifloxacin in patients with known history of myasthenia gravis.
