Generic Fluconazole Information

Introduction

Fluconazole is an oral and intravenous antifungal medication widely used in Hong Kong to treat infections caused by susceptible yeasts and molds. The active compound fluconazole belongs to the triazole class of antifungals and works by inhibiting fungal cell‑membrane synthesis. It is prescribed for a range of conditions, including oropharyngeal, esophageal, and vaginal candidiasis, cryptococcal meningitis, and systemic candidemia. The drug is available both as a generic product and under several brand names, making it a key component of antifungal therapy in the public and private health sectors of Hong Kong.

What is Fluconazole?

Fluconazole is the generic version of the original brand Diflucan, marketed by Pfizer and later by multiple generic manufacturers worldwide. Both the generic and brand formulations contain the same active compound, fluconazole, and provide equivalent therapeutic efficacy. Our online pharmacy supplies this generic alternative at a cost comparable to the manufacturer’s price, offering an affordable option for patients throughout Hong Kong.

Fluconazole is classified as a triazole antifungal. It was first synthesized in the early 199s and received regulatory approval in the United States in 199, followed by approvals in the European Union, Japan, and Hong Kong. The medication is manufactured by several reputable pharmaceutical companies that adhere to Good Manufacturing Practice (GMP) standards.

How Fluconazole Works

Fluconazole interferes with the fungal enzyme lanosterol 14α‑demethylase, which is essential for converting lanosterol to ergosterol, a critical component of the fungal cell membrane. By blocking this step, fluconazole depletes ergosterol, leading to increased membrane permeability and inhibition of fungal growth (fungistatic effect). The drug’s high affinity for the fungal enzyme, combined with limited activity against the human counterpart, yields a favorable therapeutic index.

After oral administration, fluconazole is rapidly absorbed with a bioavailability of >90 %. Peak plasma concentrations are reached within 1–2 hours. The drug is minimally metabolized and is primarily eliminated unchanged by the kidneys (approximately 80 % excreted in urine). Its long half‑life of 30–40 hours enables once‑daily dosing for many indications, while ensuring sustained therapeutic levels throughout treatment.

Conditions Treated with Fluoro​zole

• Candidiasis (oropharyngeal, esophageal, vaginal, and invasive forms). Candida species are common opportunistic pathogens in Hong Kong hospitals, especially among immunocompromised patients.
• Cryptococcal meningitis in HIV‑positive individuals or other immunodeficient groups; fluconazole is used for consolidation and maintenance therapy after induction with amphotericin B.
• Systemic candidemia and other deep‑seated Candida infections, where fluconazole serves as step‑down therapy after initial stabilization.
• Dermatophytosis caused by susceptible dermatophytes, especially when topical therapy fails.
• Prevention of fungal infections in patients undergoing bone‑marrow transplantation or prolonged neutropenia, as recommended by local infectious disease guidelines.

These indications are recognized by the Hong Kong Department of Health and are incorporated into local treatment protocols, reflecting the drug’s proven efficacy and safety profile in the regional patient population.

Suitable Candidates for Fluconazole Treatment

Fluconazole is appropriate for adult patients who:

• Have confirmed or highly suspected infection with fluconazole‑susceptible Candida or Cryptococcus species.
• Require oral maintenance therapy after initial intravenous antifungal control.
• Are unable to tolerate more toxic antifungals such as amphotericin B.
• Need prophylaxis during periods of severe immunosuppression (e.g., chemotherapy‑induced neutropenia).

Contra‑indications or cautions include:

• Known hypersensitivity to fluconazole or other triazoles.
• Severe hepatic impairment (Child‑Pugh class C), where dose adjustment or alternative therapy is advised.
• Concomitant use of drugs that are strong CYP3A4 inhibitors or inducers, which may alter fluconazole plasma levels.

Pregnant women should only use fluconazole when the potential benefit outweighs the risk, as high‑dose, prolonged exposure has been linked to congenital anomalies.

Risks, Side Effects, and Interactions

Common

• Nausea, abdominal discomfort, and diarrhoea.
• Headache or dizziness.
• Transient elevation of liver enzymes (ALT, AST).

Rare

• Cutaneous reactions such as rash, pruritus, or photosensitivity.
• Taste disturbances (dysgeusia).
• Mild thrombocytopenia or leukopenia.

Serious

• Hepatotoxicity – rare but potentially severe liver injury; patients should discontinue the drug and seek immediate medical attention if jaundice, dark urine, or persistent fatigue develop.
• Severe skin reactions – Stevens‑Johnson syndrome or toxic epidermal necrolysis; prompt discontinuation is required.
• QT prolongation – may occur in patients with existing cardiac conduction abnormalities or when combined with other QT‑prolonging agents.

Clinically Relevant Drug Interactions

• CYP2C9 substrates (e.g., warfarin, phenytoin): fluconazole can increase their plasma concentrations, necessitating dose monitoring.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): additive inhibition may raise fluconazole levels, increasing toxicity risk.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine): may reduce fluconazole effectiveness.
• Immunosuppressants (e.g., tacrolimus, cyclosporine): fluconazole raises blood levels; dosage adjustments are often required.

Patients should inform their healthcare provider of all concomitant medications, including over‑the‑counter products and herbal supplements.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing (adult).
  • Candidiasis (oral or vaginal): 150 mg single dose; for recurrent infection, 150 mg weekly for 2–6 weeks.
  • Esophageal candidiasis: 200 mg on day 1, then 100 mg daily for 2–3 weeks.
  • Cryptococcal meningitis (consolidation): 400 mg daily for at least 10 weeks, followed by a maintenance dose of 200 mg daily.
  • Prophylaxis in neutropenia: 400 mg daily throughout the neutropenic period.

Dose adjustments are required for renal impairment (creatinine clearance <50 mL/min) and hepatic dysfunction.

• Missed dose – Take the missed tablet as soon as remembered unless the next scheduled dose is within 12 hours; in that case, skip the missed dose and resume the regular regimen. Do not double‑dose.

• Overdose – Symptoms may include nausea, vomiting, dizziness, and prolonged QT interval. Contact emergency services or a poison‑information centre promptly. Activated charcoal may be considered if presentation is within one hour of ingestion.

• Precautions – Fluconazole may be taken with or without food. Alcohol does not interfere with its absorption but excessive intake should be avoided in patients with liver disease. Patients with diabetes should monitor blood glucose, as rare cases of hypoglycaemia have been reported.

FAQ

• Is Fluconazole available in both brand‑name and generic forms in Hong Kong?
  Yes, fluconazole is marketed under the original brand name Diflucan and as multiple generic versions produced by reputable manufacturers. The generic products contain the identical active ingredient and are generally less expensive.

• Does Fluconazole require refrigeration or special storage conditions?
  No, fluconazole tablets and oral suspension should be stored at room temperature, protected from light, moisture, and excessive heat. Do not keep the medication in a bathroom cabinet where humidity is high.

• What does the tablet look like, and are there any inactive ingredients that might cause allergies?
  The most common tablet is a round, film‑coated, white tablet containing lactose, microcrystalline cellulose, and magnesium stearate as excipients. Patients with severe lactose intolerance should verify the formulation with the supplier.

• Can I travel internationally with Fluconazole in my carry‑on luggage?
  Yes, fluconazole is allowed in personal medication quantities for travel. Keep the medication in its original packaging with a copy of the prescription or a doctor's note if requested by customs authorities.

• Are there differences in formulation between fluconazole sold in the US, EU, and Asian markets?
  The active ingredient concentration (e.g., 50 mg or 100 mg per tablet) is standardized worldwide, but excipients such as fillers or dyes may vary slightly to meet regional regulatory requirements. These differences do not affect clinical efficacy.

• Is fluconazole safe for patients with chronic kidney disease?
  Fluconazole is primarily eliminated unchanged by the kidneys, so dose reduction is recommended for patients with a creatinine clearance below 50 mL/min. Renal dosing guidelines should be followed under medical supervision.

• Does fluconazole interfere with common antiviral drugs used for hepatitis B or C?
  Fluconazole has minimal interaction with most nucleos(t)ide analogues for hepatitis B and direct‑acting antivirals for hepatitis C. However, clinicians should review each regimen for potential CYP‑mediated interactions.

• Can fluconazole cause false‑positive results in drug‑screening tests?
  Fluconazole does not typically affect standard immunoassay drug‑screening panels. Nevertheless, patients undergoing occupational drug testing should disclose all medications to the testing laboratory.

• What is the history behind the development of fluconazole?
  Fluconazole was discovered by Pfizer in the 198s as part of a series of triazole compounds aimed at improving the safety profile of earlier azoles. It received its first regulatory approval in 199 and quickly became a cornerstone of antifungal therapy due to its oral bioavailability and broad spectrum.

• How does fluconazole compare to older antifungal agents such as nystatin?
  Unlike nystatin, which is only effective topically or for gastrointestinal infections, fluconazole is absorbed systemically and can treat invasive candidiasis and cryptococcal meningitis. Fluconazole also has a longer half‑life, allowing once‑daily dosing, whereas nystatin often requires multiple daily applications.

Glossary

Triazole

A class of antifungal agents that contain a three‑nitrogen heterocycle; they inhibit the synthesis of ergosterol, an essential component of fungal cell membranes.

Ergosterol

The primary sterol in fungal cell membranes; disruption of its synthesis compromises membrane integrity and halts fungal growth.

CYP450 Enzyme

A family of liver enzymes (e.g., CYP3A4, CYP2C9) responsible for metabolising many drugs; inhibitors or inducers of these enzymes can alter the plasma levels of co‑administered medications.

Half‑Life

The time required for the plasma concentration of a drug to decrease by 50 %; fluconazole’s long half‑life enables once‑daily dosing.
