gemifloxacin oral Warnings
This medication may rarely cause tendon damage (e.g., tendinitis, tendon rupture) during or after treatment. Your risk for tendon problems is greater if you are over 60 years of age, if you are taking corticosteroids (such as prednisone), or if you have had a kidney, heart or lung transplant. Stop exercising, rest, and seek immediate medical attention if you develop joint/muscle/tendon pain or swelling.
gemifloxacin oral Uses
Gemifloxacin is used to treat a variety of bacterial infections. This medication belongs to a class of drugs called quinolone antibiotics. It works by stopping the growth of bacteria.
Read the Medication Guide provided by your pharmacist before you start taking gemifloxacin and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Take this medication by mouth with or without food, usually once daily or as directed by your doctor. The dosage and length of treatment is based on your medical condition and response to treatment. Drink plenty of fluids while taking this drug unless your doctor tells you otherwise.
Take this medication at least 2 hours before or 3 hours after taking any drugs that contain magnesium or aluminum. Some examples include quinapril, certain forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), vitamins/minerals, and antacids. Follow the same instructions if you take bismuth subsalicylate, iron, and zinc. Gemifloxacin should be taken at least 2 hours before sucralfate. These medications bind with gemifloxacin and prevent its full absorption.
Antibiotics work best when the amount of medicine in your body is kept at a constant level. It is important not to miss a dose. To help you remember, take this medication at the same time every day.
Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a return of the infection.
Tell your doctor if your condition persists or worsens.
gemifloxacin oral Side Effects
See also Warning section.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: skin that sunburns more easily (sun sensitivity).
Tell your doctor immediately if any of these rare but very serious side effects occur: unusual bruising/bleeding, signs of a new infection (e.g., new/persistent fever, persistent sore throat), unusual change in the amount of urine, signs of liver problems (e.g., unusual tiredness, stomach/abdominal pain, persistent nausea/vomiting, yellowing eyes/skin, dark urine).
Seek immediate medical attention if any of these rare but very serious side effects occur: chest pain, severe/persistent headache, vision changes, shaking (tremors), seizures, severe dizziness, fainting, fast/irregular heartbeat, mental/mood changes (e.g., anxiety, confusion, hallucinations, depression, rare thoughts of suicide).
Rarely, this medication may cause serious, possibly permanent, nerve problems (peripheral neuropathy). Stop taking gemifloxacin and tell your doctor right away if you have any of the following symptoms: pain/numbness/burning/tingling/weakness in your arms, hands, legs, or feet, changes in how you sense touch/pain/temperature/vibration/body position.
This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell your doctor immediately if you develop: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool.
Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection. Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.
A very serious allergic reaction to this drug is unlikely. The risk of developing a rash during gemifloxacin treatment is greater in people under age 40, in women, and also in women taking female hormone replacement medication (e.g., estrogens). This risk also increases when gemifloxacin is taken for more than 7 days. Seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: new fever, rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

gemifloxacin oral Precautions
Before using gemifloxacin, tell your doctor or pharmacist if you are allergic to it; or to other quinolone antibiotics (e.g., ciprofloxacin, levofloxacin); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: diabetes, heart problems (e.g., slow/fast/irregular heartbeat, chest pain, recent heart attack), joint/tendon problems (e.g., tendonitis, bursitis), kidney disease, myasthenia gravis, nerve problems (such as peripheral neuropathy), seizure disorder, conditions that increase your risk of seizures (e.g., brain/head injury, brain tumors, cerebral atherosclerosis).
Gemifloxacin may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using gemifloxacin, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using gemifloxacin safely.
This medication may rarely cause serious changes in blood sugar levels, especially if you have diabetes. Watch for symptoms of high blood sugar including increased thirst and urination. Also watch for symptoms of low blood sugar such as nervousness, shakiness, fast heartbeat, sweating, or hunger. Check your blood sugar regularly as directed by your doctor and report any changes. If you experience symptoms of low blood sugar, you may raise your blood sugar by using glucose tablets/gel or eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor immediately about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Your doctor may need to switch you to another antibiotic or adjust your diabetes medications if any reaction occurs.
This drug may make you dizzy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.
This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps. Use a sunscreen and wear protective clothing when outdoors.
Caution is advised when using this drug in children because they may be more sensitive to its possible side effects (e.g., joint/tendon problems). Discuss the risks and benefits with the doctor.
Older adults may be more sensitive to the side effects of this drug, such as tendon problems (especially if they are also taking corticosteroids such as prednisone or hydrocortisone) and QT prolongation (see above).
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
It is not known whether this drug passes into breast milk. Consult your doctor before breast-feeding.
