ofloxacin - oral, Floxin (cont.)
PRECAUTIONS: Before taking ofloxacin, 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: seizure disorder, conditions that increase your risk of seizures (e.g., brain/head injury, brain tumors), nervous system disorders (e.g., peripheral neuropathy), kidney disease, liver disease, myasthenia gravis, joint/tendon problems (e.g., tendonitis, bursitis).Ofloxacin 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 require immediate medical attention. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions section). Before using ofloxacin, tell your doctor or pharmacist 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 ofloxacin safely.If you have diabetes, you may experience changes in blood glucose levels due to infection or use of ofloxacin. Symptoms of high blood sugar include increased thirst and urination. Symptoms of low blood sugar include nervousness, shaking, sweating, fast heartbeat, or hunger. Follow your doctor's instructions to treat your low blood sugar level (e.g., take glucose tablets or gel; eat a quick source of sugar such as table sugar, honey, or candy; drink a glass of orange juice or non-diet soda). Tell your doctor immediately if you experience symptoms of high or low blood sugar while taking this medication. Monitor your blood glucose levels as directed by your doctor.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 medication in children younger than 18 years of age because they may be at greater risk for joint/tendon problems. Discuss the risks and benefits with the doctor.Kidney function declines as you grow older. This medication is removed by the kidneys. Therefore, the elderly may be at greater risk for tendon problems while using this drug, especially if they are also taking corticosteroids (e.g., prednisone, hydrocortisone). The elderly may also be more sensitive to the side effect of ofloxacin on the heart rhythm (QT prolongation).During pregnancy, this medication should be used only when clearly needed.
