Generic Fluconazole Information

Introduction

Fluconazole is an oral and intravenous antifungal medication widely used in the United Kingdom for the treatment and prevention of fungal infections. The active compound, fluconazole, belongs to the triazole class of antifungals and interferes with the synthesis of ergosterol, an essential component of the fungal cell membrane. It is prescribed for conditions such as candidiasis (including oropharyngeal, oesophageal, vaginal and systemic infections), cryptococcal meningitis in immunocompromised patients, and for prophylaxis in certain high‑risk clinical settings. Although primarily an anti‑fungal agent, fluconazole is occasionally employed off‑label for dermatophytosis or severe fungal infections where other agents are unsuitable.

What is Fluconazole?

Fluconazole is the generic version of Diflucan®, the original brand name introduced by Pfizer in the early 199s. Both the brand‑name and generic formulations contain the same active substance, fluconazole, and deliver equivalent therapeutic efficacy. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, sourced from qualified overseas manufacturers that meet UK regulatory standards.

The drug is classified as a systemic triazole antifungal. Its development stemmed from the need for an oral agent that could replace more toxic polyene and imidazole agents while offering a convenient dosing schedule.

How Fluconazole Works

Fluconazole inhibits the enzyme lanosterol 14‑α‑demethylase, a cytochrome P450‑dependent protein that catalyses a critical step in the conversion of lanosterol to ergosterol. By blocking this pathway, the drug reduces ergosterol production, compromising the integrity of the fungal cell membrane and leading to leakage of cellular contents and inhibited cell growth.

Because the effect is fungistatic at standard doses, fluconazole halts the replication of susceptible yeasts rather than causing rapid lysis. The onset of action is typically observed within 24 hours after the first dose, with steady‑state concentrations reached after 3–5 days of once‑daily dosing. Elimination occurs mainly via renal excretion as unchanged drug, giving a half‑life of 30–40 hours in healthy adults; hepatic impairment prolongs clearance and may require dose adjustment.

Conditions Treated with Fluconazole

Fluconazole’s high oral bioavailability (≈90 %) and long plasma half‑life make it suitable for both treatment and prophylaxis, especially where daily oral dosing enhances adherence.

Who is Fluconazole For?

Fluconazole benefits adult patients who:

• Present with Candida infections affecting the mucous membranes, skin, or bloodstream, where the organism is known to be fluconazole‑sensitive (most Candida albicans strains).
• Are immunocompromised (e.g., HIV infection, solid‑organ transplantation, chemotherapy) and require secondary prophylaxis against invasive candidiasis or cryptococcal disease.
• Cannot tolerate older azoles such as ketoconazole owing to gastrointestinal side‑effects or drug‑interaction concerns.

Conversely, fluconazole is not appropriate for patients with:

• Documented fungal species resistant to azole therapy (e.g., Candida glabrata with high MICs, Candida krusei).
• Severe hepatic impairment (Child‑Pugh C) without specialist supervision, due to reduced drug clearance and heightened toxicity risk.
• Pregnancy beyond the first trimester in the absence of specialist guidance, as category C data suggest potential fetal exposure.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset – nausea, abdominal discomfort, diarrhoea (usually mild and self‑limiting).
• Elevated liver enzymes – transaminase elevations observed in routine monitoring; often transient.

Rare

• Cutaneous reactions – rash, pruritus, and isolated cases of Stevens‑Johnson syndrome.
• Hematologic abnormalities – thrombocytopenia or neutropenia, particularly in prolonged high‑dose therapy.

Serious

• Hepatotoxicity – clinically significant hepatitis, sometimes requiring discontinuation.
• QT‑interval prolongation – rare but may precipitate torsades de pointes in patients on other QT‑prolonging agents.
• Severe hypersensitivity reactions – anaphylaxis (exceptionally rare).

Clinically Relevant Interactions

• Cytochrome P450 substrates – fluconazole can increase plasma concentrations of warfarin, phenytoin, and certain oral hypoglycaemic agents, necessitating dose adjustments.
• Other azoles – concurrent use with itraconazole or voriconazole may lead to additive toxicity.
• Terbinafine – combined use raises the risk of hepatotoxicity; avoid unless medically essential.
• HIV protease inhibitors – may increase fluconazole levels; monitor for CNS toxicity.

Patients should disclose all concomitant medicines, including over‑the‑counter products and herbal supplements, to the prescribing clinician.

Practical Use: Dosing, Missed Dose, Overdose

Standard adult dosing (oral tablets):

• Vulvovaginal candidiasis – 150 mg single dose, or 150 mg daily for 3 days.
• Oropharyngeal/oesophageal candidiasis – 200 mg on day 1, then 100 mg daily for 7–14 days.
• Systemic candidiasis – 400–800 mg on day 1, then 200–400 mg once daily until infection resolves (typically 2–4 weeks).
• Cryptococcal meningitis (adjuvant) – 400 mg once daily for 10 weeks, combined with standard antifungal induction therapy.

Doses are adjusted for renal impairment (e.g., CrCl < 50 mL/min: 50 % reduction) and for severe hepatic dysfunction (dose halving and close monitoring).

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

Overdose: Documented acute overdose of up to 2 g have not resulted in life‑threatening events. Nevertheless, any suspected excess ingestion should prompt immediate medical evaluation; supportive care focuses on monitoring liver function and cardiac rhythm.

Food and alcohol: Fluconazole can be taken with or without food. Excessive alcohol is discouraged in patients with hepatic disease, as both can increase liver stress.

FAQ

• Is Fluconazole available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name product is marketed as Diflucan® by Pfizer, while generic versions contain the same active ingredient, fluconazole, and are approved by the MHRA. Generic tablets are generally less expensive and are widely prescribed.

• Does Fluconazole require cold storage?
  No. Fluconazole tablets are stable at room temperature (15 – 30 °C). They should be kept away from direct sunlight, moisture, and extreme heat, but refrigeration is unnecessary.

• What packaging does Fluconazole take when ordered online?
  The medication is supplied in blister packs of 14 or 28 tablets per pack, each tablet being round, film‑coated, and white to off‑white. Packaging includes an outer sealed envelope with a label that lists the product name, strength (e.g., 100 mg), and expiry date.

• Can Fluconazole be safely imported for personal use in the UK?
  Personal import of a single‑dose supply of fluconazole is permitted under the UK’s “personal import” rule, provided the product is for personal medical use, the quantity does not exceed a three‑month supply, and a copy of the prescription or a professional label is available.

• Are there specific warnings for Asian populations taking Fluconazole?
  No population‑specific safety warnings have been issued by the MHRA or the WHO. However, certain studies suggest a higher prevalence of CYP2C9 polymorphisms in East Asian groups, which may modestly affect fluconazole metabolism; clinicians often monitor liver function more closely in all ethnicities.

• How does fluconazole differ from older azoles like clotrimazole?
  Unlike clotrimazole, which is primarily a topical agent, fluconazole is systemically absorbed and can treat deep‑seated infections. Moreover, fluconazole has a longer half‑life, enabling once‑daily dosing, and exhibits a broader spectrum against Candida spp.

• What is the typical duration of fluconazole prophylaxis for chemotherapy patients?
  Prophylactic regimens commonly start on day 1 of chemotherapy and continue throughout the neutropenic phase, usually 7–14 days, though duration can be extended if mucosal disruption persists.

• Does food intake affect fluconazole absorption?
  No. Fluconazole’s oral bioavailability is high and not significantly altered by meals. Patients may therefore take the medication at any convenient time relative to food.

• Is there a difference in formulation between EU and US fluconazole products?
  EU‑licensed generic formulations must meet the European Pharmacopoeia standards, while US products adhere to the United States Pharmacopeia. In practice, excipients such as lactose, starch, or magnesium stearate may vary, potentially affecting tablet size or dissolution speed, but therapeutic equivalence is maintained.
