Flocet200 mg

Flocet is a fluoroquinolone antibiotic used to treat infections caused by susceptible strains of bacteria. Because fluoroquinolones carry serious risks (see Precautions and Warnings), Flocet is generally reserved for infections without a suitable alternative treatment option.

Established / FDA-approved uses

• Acute bacterial exacerbation of chronic bronchitis
• Community-acquired pneumonia (mild to moderate, due to susceptible organisms)
• Uncomplicated and complicated urinary tract infections (UTI), including acute pyelonephritis
• Uncomplicated skin and skin structure infections
• Acute, uncomplicated urethritis and cervicitis due to Chlamydia trachomatis or Neisseria gonorrhoeae (where local susceptibility is confirmed)
• Mixed infections of the urethra and cervix
• Chronic bacterial prostatitis due to Escherichia coli
• Ophthalmic solution: bacterial conjunctivitis and corneal ulcers caused by susceptible organisms
• Otic solution: acute otitis externa, chronic suppurative otitis media with perforated tympanic membrane, and acute otitis media in children with tympanostomy tubes

Important note on gonorrhea

Due to widespread resistance, fluoroquinolones including Flocet are no longer recommended by public health authorities (e.g. CDC) as first-line therapy for gonorrhea in most regions; use should be guided by local susceptibility testing and current treatment guidelines.

Each formulation of Ofloxacin contains Ofloxacin as the active pharmaceutical ingredient. Common presentations include:

• Oral tablets (e.g. 200 mg, 400 mg)
• Intravenous infusion solution
• Ophthalmic solution (e.g. 0.3%)
• Otic (ear) solution (e.g. 0.3%)

Inactive ingredients vary by manufacturer and formulation; refer to the specific product label for excipient details.

Flocet is a synthetic broad-spectrum fluoroquinolone antibacterial agent. It is active against a range of Gram-negative and some Gram-positive organisms and is used to treat various bacterial infections of the respiratory tract, urinary tract, skin, reproductive tract, and, in topical formulations, the eye and ear.

Flocet works by interfering with bacterial DNA replication, leading to bacterial cell death (bactericidal activity).

Flocet belongs to the fluoroquinolone class of antibacterial agents.

Ofloxacin exerts its bactericidal effect by inhibiting two essential bacterial enzymes, DNA gyrase (topoisomerase II) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination. Inhibition of these enzymes causes double-strand breaks in bacterial DNA, leading to rapid bacterial cell death.

Pharmacokinetics

• Absorption: Rapidly and almost completely absorbed after oral administration; bioavailability is approximately 98%.
• Distribution: Widely distributed into body tissues and fluids; protein binding is low (approximately 32%).
• Metabolism: Minimally metabolized in the liver.
• Excretion: Primarily eliminated unchanged in the urine via renal excretion; elimination half-life is approximately 4-8 hours in patients with normal renal function.

Flocet tablets should be swallowed whole with a full glass of water, with or without food, though consistent timing relative to meals is recommended. Tablets should not be crushed or split unless directed. Avoid taking Flocet with antacids, sucralfate, or multivitamins/mineral supplements containing iron or zinc at the same time (see Interactions) — separate dosing by at least 2 hours before or 6 hours after these products.

Ophthalmic solution: Tilt the head back, pull down the lower eyelid, and instill the prescribed number of drops into the pocket formed. Avoid touching the dropper tip to the eye or any surface. Do not wear contact lenses during treatment of an eye infection.

Otic solution: Warm the bottle in the hand before use. Lie down with the affected ear upward, instill the prescribed number of drops, and remain in that position for several minutes.

Flocet has several clinically significant drug interactions:

• Antacids, sucralfate, and multivalent cation supplements (aluminum, magnesium, calcium, iron, zinc): Significantly reduce absorption of oral Flocet. Separate administration by at least 2 hours before or 6 hours after these products.
• QT-prolonging drugs (e.g. Class IA/III antiarrhythmics, certain antipsychotics): Additive risk of QT interval prolongation and torsades de pointes; avoid combination when possible.
• Corticosteroids (systemic): Increased risk of tendinitis and tendon rupture, particularly in elderly patients; use with caution.
• Theophylline: Flocet may increase theophylline plasma concentrations, raising the risk of toxicity (nausea, seizures, cardiac arrhythmia); monitor theophylline levels if co-administered.
• Warfarin and other oral anticoagulants: Flocet may potentiate anticoagulant effects; monitor INR/prothrombin time closely.
• NSAIDs: May increase the risk of central nervous system stimulation and seizures when combined with fluoroquinolones.
• Oral antidiabetic agents (e.g. glyburide) or insulin: May cause disturbances of blood glucose (hypoglycemia or hyperglycemia); monitor blood glucose closely.

Side effects of Flocet vary by route of administration.

Systemic (oral/IV) use — common

• Nausea, vomiting, diarrhea, abdominal pain
• Headache, dizziness, insomnia
• Vaginitis

Systemic use — serious (require prompt medical attention)

• Tendinitis and tendon rupture (see Precautions and Warnings)
• Peripheral neuropathy, which may be irreversible
• Central nervous system effects: seizures, increased intracranial pressure, confusion, hallucinations, psychiatric disturbances
• QT interval prolongation and risk of serious cardiac arrhythmia
• Hypersensitivity reactions, including severe skin reactions and anaphylaxis
• Clostridioides difficile-associated diarrhea (can range from mild to life-threatening colitis)
• Photosensitivity/phototoxic skin reactions
• Hepatotoxicity (rare)
• Disturbances in blood glucose

Ophthalmic/otic use

Local irritation, burning, itching, or discomfort at the site of application; bitter taste (with otic use) is possible. Systemic absorption and systemic side effects are much less likely with these routes compared to oral or intravenous use.

Pregnancy: Flocet should be used during pregnancy only if clearly needed and the potential benefit justifies the potential risk to the fetus. Fluoroquinolones as a class have been associated with musculoskeletal effects (arthropathy) in juvenile animal studies, and safety data in human pregnancy are limited; a physician should be consulted before use, and alternative agents with a better-established safety profile should be considered when appropriate.

Lactation: Flocet is excreted into human breast milk. Because of the potential for adverse effects on the nursing infant (including joint/cartilage effects reported with the fluoroquinolone class), a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother; consult a physician.

Ophthalmic and otic formulations result in much lower systemic exposure than oral or intravenous use, but caution and physician guidance are still advised during pregnancy and breastfeeding.

Flocet belongs to the fluoroquinolone class of antibiotics, which carries several serious safety warnings recognized by regulatory authorities:

• Tendinitis and tendon rupture: Risk is increased in elderly patients, those taking corticosteroids, and organ transplant recipients. Discontinue Flocet immediately and rest the affected area if pain, swelling, or inflammation of a tendon occurs.
• Peripheral neuropathy: May occur rapidly after starting Flocet and, in some cases, may be irreversible. Discontinue immediately if symptoms of neuropathy (pain, burning, tingling, numbness, weakness) develop.
• Central nervous system effects: May cause seizures, increased intracranial pressure, dizziness, confusion, and psychiatric disturbances (including suicidal thoughts, rare); use with caution in patients with known or suspected CNS disorders.
• Exacerbation of myasthenia gravis: Fluoroquinolones may worsen muscle weakness in patients with myasthenia gravis, including risk of respiratory failure; avoid in this population.
• QT prolongation: Use with caution in patients with known QT prolongation, uncorrected electrolyte disturbances, or concomitant use of QT-prolonging drugs.
• Photosensitivity: Moderate to severe photosensitivity/phototoxicity reactions can occur; patients should avoid excessive sunlight or artificial UV light and use sun protection during treatment.
• Clostridioides difficile-associated diarrhea: May range from mild diarrhea to fatal colitis; seek medical attention if severe or persistent diarrhea develops.
• Hypersensitivity reactions: Serious and occasionally fatal reactions have been reported, sometimes after a single dose.
• Blood glucose disturbances: Both hypoglycemia and hyperglycemia have been reported, particularly in diabetic patients on concomitant oral hypoglycemic agents or insulin.

Antibiotic stewardship: Take Flocet exactly as prescribed by your physician; do not stop, extend, skip doses, or share this medicine with others without medical advice.

In case of a suspected Flocet overdose, seek immediate medical attention or contact a poison control center/emergency services right away. Reported overdose symptoms may include nausea, dizziness, and, in severe cases, more pronounced central nervous system or cardiac effects. There is no specific antidote; management is supportive and symptomatic, and may include monitoring in a medical facility. Do not attempt to manage a suspected overdose at home.

Store at room temperature (below 30°C), away from light and moisture. Keep out of reach of children. Ophthalmic and otic solutions should be discarded per the product's stated in-use shelf life after opening.

Pediatric use

Systemic Flocet is generally not recommended for use in patients under 18 years of age because of the risk of arthropathy (joint/cartilage damage) observed in immature animals, except in specific situations where a physician determines the benefit outweighs the risk. Certain otic formulations may be approved for specific pediatric age groups (e.g. otitis externa, otitis media with tympanostomy tubes) — refer to product labeling and consult a pediatrician.

Elderly (geriatric) use

Elderly patients are at increased risk of tendinitis and tendon rupture, especially when taking corticosteroids concurrently, and may also be at higher risk of QT prolongation. Use with caution and appropriate monitoring.

Renal impairment

Dose or dosing interval adjustment is required in patients with creatinine clearance below 50 mL/min; consult a physician for individualized dosing.

Hepatic impairment

Use with caution; dose adjustment may be required in patients with significant hepatic impairment. Consult a physician.

The duration of Flocet treatment depends on the indication, typically ranging from 3 days (uncomplicated UTI) to 10 days (respiratory tract, complicated UTI, skin infections) or up to 6 weeks (chronic bacterial prostatitis). The full prescribed course should always be completed, even if symptoms improve earlier, unless a physician advises otherwise.

Ofloxacin is classified as a fluoroquinolone antibacterial agent, part of the broader quinolone class of synthetic antibiotics.

Ofloxacin acts by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA supercoiling, replication, and repair. By blocking these enzymes, Ofloxacin prevents bacterial DNA from replicating properly, resulting in bactericidal (bacteria-killing) activity.

C

Flocet is generally not approved for systemic use in patients younger than 18 years due to the risk of arthropathy (cartilage/joint damage) demonstrated in juvenile animal studies; safety and efficacy of systemic Flocet in this population have not been established except in select situations where a physician determines benefits outweigh risks. Certain otic (ear) formulations of Flocet are approved for use in specific pediatric age groups (e.g. from 6 months to 12 years for select indications, depending on the product) — always follow the product labeling and pediatrician's guidance.
