Generic Levofloxacin Information

Introduction

Levofloxacin is a broad‑spectrum antibacterial medication classified as a fluoroquinolone. It is commonly prescribed for a variety of bacterial infections in adult patients in Hong Kong. The active compound is levofloxacin, and the drug belongs to the antibacterial group. In addition to its primary role in treating respiratory and urinary tract infections, levofloxacin is also indicated for skin infections, abdominal infections, and certain sexually transmitted infections when susceptibility testing supports its use.

What is Levofloxacin?

Levofloxacin is the generic version of Levaquin®, a brand originally developed by Daiichi Sankyo and subsequently marketed worldwide. Both the generic and branded products contain the same active compound, levofloxacin, and demonstrate equivalent antimicrobial activity when manufactured according to Good Manufacturing Practice. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for patients in Hong Kong who need reliable antibacterial therapy.

How Levofloxacin Works

Levofloxacin interferes with bacterial DNA replication by inhibiting the enzymes DNA gyrase (topoisomerase II) and topoisomerase IV. These enzymes are essential for supercoiling and relaxing bacterial DNA during replication and transcription. By binding to the enzyme–DNA complex, levofloxacin prevents the resealing of DNA strands, leading to accumulation of double‑strand breaks and bacterial cell death. The drug achieves bactericidal activity shortly after absorption, with peak plasma concentrations typically reached within 1–2 hours after oral dosing. Renal excretion accounts for most of the clearance, giving a half‑life of approximately 6–8 hours in individuals with normal kidney function.

Conditions Treated with Levofloxacin

• Community‑acquired bacterial pneumonia (CAP) – Levofloxacin provides coverage against typical (Streptococcus pneumoniae) and atypical (Mycoplasma, Chlamydophila) pathogens, which are prevalent in Hong Kong’s dense urban environment.
• Acute exacerbations of chronic bronchitis – Effective against Haemophilus influenzae, Moraxella catarrhalis, and resistant Streptococcus pneumoniae strains.
• Complicated urinary tract infections (cUTI) and pyelonephritis – Active against Escherichia coli, Klebsiella pneumoniae, and Enterobacter spp., common causes of cUTI in Hong Kong hospitals.
• Skin and soft‑tissue infections – Covers Staphylococcus aureus (including some methicillin‑susceptible isolates) and Streptococcus pyogenes.
• Intra‑abdominal infections – When combined with metronidazole, levofloxacin treats mixed aerobic and anaerobic infections originating from the gastrointestinal tract.
• Sexually transmitted infections (STI) such as uncomplicated gonorrhoea – Recommended in regions where susceptibility to fluoroquinolones remains high; however, local resistance patterns must be consulted.

Who is Levofloxacin For?

Levofloxacin is appropriate for adult patients (≥ 18 years) who have a confirmed or strongly suspected bacterial infection susceptible to fluoroquinolones and for whom first‑line agents (e.g., amoxicillin, macrolides) are contraindicated, ineffective, or unavailable. Typical scenarios include:

• Patients with severe CAP who require a single‑dose oral regimen or who cannot tolerate beta‑lactams.
• Individuals with cUTI who have a history of beta‑lactam allergy.
• Travelers returning to Hong Kong with acute respiratory infections acquired abroad where resistant organisms are prevalent.

Levofloxacin is not recommended for:

• Children, pregnant or lactating women, because of potential effects on cartilage and fetal development.
• Patients with a known hypersensitivity to fluoroquinolones.
• Those with a history of tendon disorders related to fluoroquinolone use, uncontrolled epilepsy, or severe renal impairment (creatinine clearance < 30 mL/min) without dose adjustment.

Risks, Side Effects, and Interactions

Common

• Nausea, vomiting, or dyspepsia.
• Headache or dizziness.
• Diarrhoea, which is usually mild and self‑limiting.

Rare

• Photosensitivity reactions manifested as skin rash after sun exposure.
• Elevated liver enzymes (ALT, AST) without clinical hepatitis.
• Minor QT interval prolongation on electrocardiogram in susceptible individuals.

Serious

• Tendon rupture (especially Achilles tendon) or tendinitis, more common in patients over 60 years or those on corticosteroids.
• Peripheral neuropathy, presenting as tingling, numbness, or burning sensations.
• Central nervous system effects such as seizures, confusion, or hallucinations, particularly in patients with renal dysfunction or concurrent CNS‑active drugs.
• Severe allergic reactions (anaphylaxis, Stevens‑Johnson syndrome, toxic epidermal necrolysis).

Drug–drug interactions

• Antacids containing aluminium, magnesium, calcium, or iron: Reduce levofloxacin absorption; separate administration by at least 2 hours.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): May increase the risk of central nervous system stimulation.
• Warfarin: Levofloxacin can potentiate anticoagulant effect; monitor INR closely.
• Cytochrome P450‑interacting drugs (e.g., theophylline, caffeine): Fluoroquinolones may increase serum concentrations; dosage adjustments may be required.
• Corticosteroids: Concomitant use heightens the risk of tendon rupture; avoid unless absolutely necessary.

Practical Use: Dosing, Missed Dose, Overdose

• Standard oral dosing for uncomplicated CAP: 500 mg once daily for 7–10 days; 750 mg once daily for severe CAP (≥ 65 years or comorbidities) for 5–7 days.
• Complicated urinary tract infection: 750 mg once daily for 7 days.
• Skin and soft‑tissue infection: 500 mg once daily for 7‑10 days.

All doses are administered with a full glass of water. Food does not significantly affect absorption but may lessen gastrointestinal upset; patients may take the tablet with or without meals.

Missed dose: Take the forgotten dose as soon as remembered unless it is within 12 hours of the next scheduled dose. In that case, skip the missed dose and continue the regular schedule. Do not double‑dose.

Overdose: Symptoms may include severe nausea, vomiting, dizziness, or seizures. Seek immediate medical attention; activated charcoal may be used if presentation is early. No specific antidote exists.

Precautions

• Assess renal function before initiation; adjust dose for creatinine clearance < 50 mL/min (e.g., 500 mg every 48 hours).
• Avoid excessive alcohol, as it may worsen dizziness or gastrointestinal irritation.
• Patients with a history of cardiac arrhythmia should have baseline ECG monitoring because of potential QT prolongation.

FAQ

• Is levofloxacin available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is marketed as Levaquin®, while numerous generic manufacturers produce levofloxacin tablets that contain the same active ingredient. Generic versions are typically less expensive and are approved by local health authorities.

• What is the recommended storage condition for levofloxacin tablets?
  Store the tablets at room temperature, between 15 °C and 30 °C, in a dry place away from direct sunlight and moisture. Do not refrigerate or freeze the medication, and keep it out of reach of children.

• Can levofloxacin be taken with dairy products or calcium‑rich foods?
  While levofloxacin’s absorption is not dramatically altered by food, calcium‑containing products (milk, cheese, calcium supplements) can reduce its bioavailability. It is advisable to separate the dose from calcium‑rich meals by at least two hours.

• Does levofloxacin cross the blood‑brain barrier, and could it cause central nervous system effects?
  Levofloxacin penetrates the cerebrospinal fluid to a modest degree, which explains rare reports of seizures, confusion, or hallucinations, especially in patients with renal impairment or concurrent CNS‑active drugs.

• Are there any regional differences in the inactive ingredients of levofloxacin tablets?
  Yes. Formulations marketed in the United States, Europe, and Asia may contain different excipients such as lactose, corn starch, or mannitol. Patients with specific allergies should review the product’s ingredient list provided by the supplier.

• What are the Hong Kong import rules for personal use of levofloxacin?
  Hong Kong permits individuals to import a three‑month supply of prescription medicines for personal use, provided the product is for personal consumption and is not for resale. Documentation such as a copy of the prescription and a valid identification card may be required at customs.

• Can levofloxacin cause false‑positive results on drug‑screening tests?
  Fluoroquinolones are not known to interfere with standard immunoassay drug‑screening panels. However, they may affect certain specialized laboratory assays, such as those measuring serum electrolytes, so clinicians should inform the laboratory if the patient is taking levofloxacin.

• How does levofloxacin compare with older fluoroquinolones like ciprofloxacin?
  Levofloxacin is the L‑isomer of ofloxacin and generally provides higher potency against Gram‑positive organisms, including Streptococcus pneumoniae, while maintaining similar activity against Gram‑negative bacteria. This broader spectrum often allows once‑daily dosing, whereas ciprofloxacin usually requires twice‑daily administration.

• Is there any evidence linking levofloxacin use to tendon injuries in Asian populations?
  Large‑scale pharmacovigilance studies have identified tendon disorders as a class effect of fluoroquinolones across ethnicities, including Asian cohorts. The absolute risk remains low, but clinicians advise caution in patients over 60 years, those on corticosteroids, or individuals with recent orthopedic surgery.

• What should a traveler to mainland China do if they need levofloxacin during the trip?
  Travelers should carry a sufficient personal supply in their original packaging, accompanied by a copy of the prescribing doctor’s note. Upon arrival, they may need to present this documentation to customs officials if asked, adhering to Hong Kong’s personal import allowance.

• Why do some levofloxacin tablets have a film coating and others do not?
  Film‑coated tablets are designed to mask taste and improve swallowability. Non‑coated tablets may be used in settings where patients have difficulty with swallowing or when a rapid disintegration is desired. Both forms deliver the same dose of active ingredient.

• Are there any known interactions between levofloxacin and herbal supplements such as ginkgo biloba?
  Ginkgo biloba possesses antiplatelet activity, which could theoretically increase bleeding risk when combined with levofloxacin‑induced platelet function alteration. While clinical evidence is limited, patients should discuss supplement use with their healthcare provider.
