Floxin (Ofloxacin)

Floxin Oral Tablet

Do you have an infection that has not responded well to other antibiotics? In some cases, a clinician may prescribe Floxin. It is an antimicrobial medication containing ofloxacin, a fluoroquinolone antibiotic. It works against a range of gram-negative bacteria and some gram-positive bacteria. Like other systemic fluoroquinolones, ofloxacin can cause serious side effects, including tendon problems and central nervous system effects, so it should be used only when the potential benefits outweigh the risks and exactly as prescribed.

What is Floxin?

Ofloxacin is a fluoroquinolone antibiotic. It works by blocking bacterial DNA gyrase and topoisomerase IV, which are needed for bacterial DNA replication. Ofloxacin is well absorbed when taken by mouth and has high bioavailability. The elimination half-life is about 4-5 hours in younger adults and may be longer in older adults. Taking Floxin with food does not significantly affect overall exposure, but it may delay the time to peak levels.

Floxin (ofloxacin) tablets are authorized in Canada for certain infections in adults, including selected respiratory infections such as community-acquired pneumonia and acute bacterial exacerbations of chronic bronchitis, uncomplicated skin and skin structure infections, and several genitourinary infections, including certain UTIs, prostatitis due to E. coli, pelvic inflammatory disease, and specific sexually transmitted infections as described in the Canadian product monograph. Your clinician will choose the regimen based on the type of infection and your individual risk factors.

What is Floxin Otic Used For?

This medication comes in several forms. One of them is Floxin Otic (ofloxacin otic solution 0.3%), which is used only for ear infections and should not be used in the eyes. According to the Canadian product monograph, Floxin Otic is used for selected ear infections, including otitis externa (an ear canal infection) in patients 6 months and older; some middle-ear indications have different minimum ages. It is important to remember that Floxin Otic should not be taken by mouth.

Before Taking This Medicine

Before starting treatment, review the prescribing information and discuss your medical history with a clinician. Tell your healthcare provider if you have kidney problems (a dose adjustment may be needed if your kidney function is reduced), a history of tendon problems, seizures or other central nervous system disorders, heart rhythm problems (QT prolongation), diabetes (as blood sugar changes can occur), or myasthenia gravis.

If you may be allergic to ofloxacin or other quinolone antibiotics, do not take chances. Make sure you are not allergic to this active ingredient before taking the tablet.
There are no adequate, well-controlled studies in pregnant women; ofloxacin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Because of the potential for serious side effects in nursing infants, a decision should be made whether to stop nursing or stop the drug, taking into account how important the drug is to the mother. Do not take this medication without a prescription.

How to Use the Floxin Tablet?

Floxin oral tablets should be taken by mouth exactly as directed. Swallow the tablet with water. Many regimens are taken every 12 hours, depending on the infection being treated. Do not change the dose or treatment duration on your own, and do not stop early just because you feel better. This can increase the risk of treatment failure and antibiotic resistance.

It is important to drink enough fluids during treatment. If you miss a dose, take it as soon as you remember unless it is almost time for your next dose. Do not take two doses at once.

Who Shouldn't Take Floxin?

Do not take Floxin if you have had a serious hypersensitivity reaction to ofloxacin or other quinolone antibiotics. Safety and effectiveness in pediatric patients and adolescents (under 18 years of age), pregnant women, and breastfeeding women have not been established for Floxin tablets; use in these groups requires careful medical judgment about risks and benefits.

Floxin Side Effects

Like other medications, Floxin may cause side effects. Some need urgent medical attention. Get help right away if you have signs of a severe allergic reaction, such as trouble breathing, swelling of the face or throat, or a severe rash; tendon pain or swelling, especially in the Achilles tendon; severe dizziness, confusion, or hallucinations; severe diarrhea; chest pain or fainting; or symptoms of low blood sugar, especially if you have diabetes.

• Side effects requiring immediate medical attention: severe allergic reaction, tendon pain/swelling or tendon rupture, severe CNS effects (e.g., seizures, hallucinations), severe diarrhea, chest pain/fainting, or severe low blood sugar symptoms.
• Other side effects may include headache, dizziness, nausea, insomnia, or mood changes. Contact a healthcare professional if side effects are bothersome or do not go away.

Women may notice vaginal itching or discomfort. Get medical help if symptoms become severe or if you are concerned.

Floxin Dosage

The dose depends on the type of infection, your kidney function, and other individual factors. In adults with normal renal function, labelled regimens commonly use 200 to 400 mg every 12 hours (or a single-dose regimen for certain infections), but the exact dose and duration vary by indication. If you have reduced kidney function (creatinine clearance <50 mL/min), a dose adjustment is necessary.

For children

Floxin (ofloxacin) oral tablets are not approved for pediatric patients under 18 years of age. Floxin Otic has labelled pediatric use for certain ear infections starting at 6 months of age, with different minimum ages depending on the specific middle-ear condition. A clinician should determine the appropriate product and regimen.

For adults

Follow your prescription label. For many labelled adult indications, dosing is every 12 hours, and the exact dose and duration depend on the infection being treated. Tell your clinician if you have kidney disease, because dose adjustments may be required.

Overdose

In case of overdose, get urgent medical attention or contact Poison Control. If your condition gets worse or you develop severe symptoms, call emergency services.

Missed Dose

If you miss a dose, take it as soon as you remember unless it is close to your next scheduled dose. Do not take a double dose.

What Should I Avoid While Taking Floxin?

Ofloxacin can cause dizziness or other nervous system effects in some people. Avoid driving or operating machinery until you know how this medication affects you. Fluoroquinolones can also be associated with photosensitivity, so avoid excessive sun or UV exposure and use sun protection.

Alcohol may make side effects such as dizziness worse, so it is best to avoid or limit alcohol during treatment.

What Other Drugs Affect This Drug?

Tell your clinician and pharmacist about all medications and supplements you take. Do not take ofloxacin within 2 hours before or after antacids containing calcium, magnesium, or aluminum; sucralfate; iron; zinc-containing multivitamins; or didanosine, because they can reduce absorption. Also discuss medications that may prolong the QT interval or increase the risk of tendon injury, such as systemic corticosteroids, as well as diabetes medications because blood sugar changes can occur.

Conclusion

Now you know what Floxin (ofloxacin) is and how it is commonly used. Take it exactly as prescribed, and do not stop early without medical advice. Because fluoroquinolones can cause serious side effects, contact a healthcare professional promptly if you develop unusual symptoms, such as tendon pain, severe dizziness or confusion, a severe rash, or signs of low blood sugar. Your clinician may recommend monitoring, including blood glucose in some patients, especially during prolonged therapy or if you have other medical conditions.
