Generic Griseofulvin Information

Introduction

Griseofulvin is an oral antifungal agent that has been used for several decades to treat dermatophyte infections of the skin, hair and nails. In Hong Kong it is classified as a “Anti‑Fungal” drug and is listed on the Hong Kong Department of Health’s formulary for superficial mycoses. The active compound, Griseofulvin, is produced by various manufacturers and is also available under well‑known brand names such as Gris‑PEG® and Sporicidin®. Although the medication was originally developed for dermatophyte infections, clinicians in Hong Kong occasionally prescribe it off‑label for rare fungal infections when alternative agents are unsuitable.

What is Griseofulvin?

Griseofulvin is the generic version of the original branded products Gris‑PEG® and Sporicidin®, containing the same active compound, Griseofulvin. It belongs to the quinone class of antifungal agents and is administered orally as tablets. The drug was first isolated from the soil fungus Penicillium species in the 193s and received FDA approval in 1958 for the treatment of fungal skin infections. Multiple manufacturers worldwide produce standardized tablets that meet pharmaco‑peia specifications for potency, purity and dissolution. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, delivering the same therapeutic benefit as the brand‑name products while maintaining strict quality control.

How Griseofulvin Works

Griseofulvin interferes with the synthesis of fungal microtubules, a structure essential for cell division. By binding to β‑tubulin, the drug prevents the formation of the mitotic spindle, thereby inhibiting mitosis and halting fungal growth. The inhibition is fungistatic rather than fungicidal; however, because the drug accumulates in keratinous tissue (skin, nails and hair) it creates a hostile environment for dermatophytes that rely on keratin as a nutrient source. Therapeutic concentrations are typically achieved within 48 hours of the first dose, and steady‑state levels are maintained throughout the standard 2‑ to 6‑week treatment course. Griseofulvin is metabolised in the liver to several inactive hydroxylated metabolites and is excreted mainly via the bile into the feces; a small fraction is eliminated unchanged in the urine.

Conditions Treated with Griseofulvin

• Tinea corporis (ringworm) and tinea pedis (athlete’s foot) – superficial dermatophyte infections of the trunk or feet are common in humid environments; Hong Kong’s subtropical climate contributes to a higher prevalence of these conditions. Griseofulvin penetrates infected skin and inhibits fungal replication, leading to clinical resolution.
• Tinea capitis (scalp ringworm) – especially in children and adolescents, the infection spreads rapidly through hair shafts. Oral therapy is required because topical agents cannot reach the hair follicle.
• Tinea unguium (onychomycosis) – infection of the nail plate is persistent and often recalcitrant to topical treatment; griseofulvin’s high keratin affinity provides a therapeutic advantage.
• Rare or recalcitrant superficial mycoses – in certain immunocompromised patients, dermatophyte infections may be extensive. When newer agents (e.g., terbinafine, itraconazole) are contraindicated, griseofulvin remains an evidence‑based alternative.

The drug is not indicated for invasive systemic mycoses, candidiasis or opportunistic infections such as Candida or Aspergillus species.

Suitable Candidates for Griseofulvin Treatment

• Patients with confirmed dermatophyte infections of skin, scalp or nail, diagnosed by clinical examination and mycological culture.
• Children (≥ 2 years) with tinea capitis – oral therapy is preferred because the infection involves the hair shaft.
• Adults with extensive or chronic tinea corporis/pedis who have not responded to topical agents or who have multiple lesions.
• Immunocompetent individuals where the infection remains superficial; griseofulvin’s safety profile is favourable in this group.

Contraindications or cautionary use includes:

• Pregnant or lactating women (category C – potential fetal risk).
• Patients with severe hepatic impairment, because the drug is hepatically metabolised.
• Individuals taking medications that significantly induce hepatic enzymes (e.g., rifampicin, carbamazepine) may experience reduced efficacy.

Risks, Side Effects, and Interactions

Common adverse events

• Gastro‑intestinal discomfort (nausea, abdominal pain, dyspepsia) – reported in up to 15 % of patients; usually transient and mitigated by taking tablets with food.
• Skin reactions (pruritus, rash, photosensitivity) – especially in patients exposed to strong sunlight; photoprotective clothing is advised.

Rare adverse events

• Hepatotoxicity – abnormal liver function tests occur in <1 % of users; routine monitoring is recommended for prolonged therapy.
• Hematological abnormalities (eosinophilia, leukopenia) – isolated case reports; patients with pre‑existing bone‑marrow disorders should be assessed before initiation.

Serious adverse events

• Stevens‑Johnson syndrome or toxic epidermal necrolysis – extremely rare but life‑ threatening; immediate discontinuation and emergency medical care are required.
• Severe hepatic failure – documented in a handful of cases with concomitant hepatotoxic drugs; a comprehensive medication review is essential.

Drug–drug interactions

• CYP450 inducers (e.g., rifampicin, carbamazepine, phenobarbital) → increased metabolism → subtherapeutic levels.
• CYP450 inhibitors (e.g., ketoconazole, erythromycin) → may raise griseofulvin concentration, increasing risk of toxicity.
• Warfarin – griseofulvin may potentiate anticoagulant effect; INR should be monitored closely.
• Contraceptive steroids – co‑administration may reduce efficacy of oral contraceptives; a backup method is recommended.

Patients should disclose all current medicines, including over‑the‑counter products and herbal supplements, to avoid clinically significant interactions.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing: 500 mg (four 125 mg tablets) taken twice daily on the first week, then once daily for the remainder of therapy. The total treatment period ranges from 2 weeks (tinea corporis) to 6 weeks (onychomycosis), depending on clinical response and mycological clearance.
• Pediatric dosing: 10–20 mg/kg/day divided into two doses; the same tapering schedule is applied.
• Missed dose: If a dose is forgotten, it should be taken as soon as remembered unless the next scheduled dose is imminent; in that case, skip the missed dose and continue the regular schedule. Doubling the dose to “catch up” is contraindicated.
• Overdose: Acute accidental ingestion of more than 10 g may lead to severe gastrointestinal irritation, hepatic dysfunction and central nervous system depression. Immediate medical evaluation, supportive care and monitoring of liver enzymes are required.
• Food and alcohol: Griseofulvin is best absorbed with a low‑fat meal; high‑fat foods can reduce plasma levels. Alcoholic beverages should be limited because they increase hepatic burden and may exacerbate photosensitivity.

FAQ

• Is Griseofulvin available in both brand‑name and generic forms in Hong Kong?
  Yes. The medication is marketed under brand names such as Gris‑PEG® and Sporicidin®, while generic tablets containing the identical active compound are sold through reputable distributors, including our online pharmacy.

• How should Griseofulvin be stored during Hong Kong’s humid climate?
  Store the tablets at room temperature (15 – 30 °C) in a dry place, protected from direct sunlight and moisture. A sealed plastic container inside a cabinet is preferable to bathroom storage, where humidity can be high.

• What appearance do the generic tablets have compared to the original brand?
  Generic griseofulvin tablets are typically white, round, and film‑coated, often bearing a faint imprint of the manufacturer’s logo and “125 mg” on each side. Brand‑name tablets may differ in shape or color but contain the same dosage strength.

• Can I travel internationally with Griseofulvin in my carry‑on bag?
  Yes, provided you retain the original packaging, a copy of the prescription, and a brief statement of medical necessity. Upon arrival in another jurisdiction, you may be asked to present the documentation to customs officers.

• Does Griseofulvin require refrigeration for stability?
  No. The drug is stable at standard ambient temperatures and does not need cold storage.

• Are there special warnings for patients of Asian descent?
  Some pharmacogenomic studies suggest a higher prevalence of CYP2C19 variant alleles in East Asian populations, potentially affecting griseofulvin metabolism. Clinicians often monitor liver function more closely in Asian patients receiving long‑term therapy.

• How does Griseofulvin’s efficacy compare with newer oral antifungals such as terbinafine?
  Clinical trials indicate terbinafine achieves faster mycological cure rates for tinea unguium, while griseofulvin remains effective for tinea capitis and extensive dermatophyte infections, particularly when drug‑drug interactions preclude terbinafine use.

• What is the typical length of a treatment course for tinea capitis in children?
  The standard regimen is 8 weeks of daily dosing (250 mg / day for children weighing 10 kg – 20 kg). Clinical cure is often confirmed by negative culture at 4 weeks, but therapy is continued to ensure complete eradication.

• Are there any known counterfeit forms of Griseofulvin on the Hong Kong market?
  Counterfeit products are rare for this specific medication, but patients are advised to obtain griseofulvin only from accredited pharmacies or through our verified online pharmacy to guarantee authenticity.

• Can I purchase Griseofulvin without a prescription for personal use?
  While the medication is technically a prescription drug, Hong Kong allows personal import of a three‑month supply for self‑care with a valid medical assessment. Our online pharmacy requires a valid prescription upload before dispatch.
