Generic Grifulvin V Information

Introduction

Grifulvin V is an oral antifungal medication that contains the active compound Griseofulvin. It belongs to the Griseofulvin class of systemic antifungal agents and is used primarily for the treatment of dermatophyte infections of the skin, hair, and nails. In Hong Kong, Grifulvin V is prescribed when topical therapy is insufficient or when the infection involves extensive skin areas, deep‑seated lesions, or the scalp. The medication is manufactured by licensed pharmaceutical companies that meet the standards of the Hong Kong Department of Health.

What is Grifulvin V?

Grifulvin V is a tablet formulation that delivers the antifungal agent Griseofulvin. Griseofulvin is a natural product derived from the mold Penicillium rubens and has been used clinically since the 195s. The drug is classified as a systemic anti‑fungal (antimycotic) and is marketed under various brand names worldwide, including Grifulvin V, Griseofulvin Tablets, and others. The formulation is designed for oral administration, typically in the form of film‑coated tablets of 250 mg or 500 mg strength.

How Grifulvin V Works

Griseofulvin interferes with fungal cell division by binding to microtubules, the structural filaments that separate chromosomes during mitosis. This binding disrupts the formation of the mitotic spindle, halting fungal cell proliferation. The drug is fungistatic rather than fungicidal; it inhibits growth and allows the immune system to clear the infection. After oral ingestion, Griseofulvin is absorbed slowly, with peak plasma concentrations occurring 2–4 hours after dosing. The drug distributes preferentially to keratinized tissues (skin, hair, nails), where it remains at therapeutic concentrations for weeks after treatment has stopped. Elimination is primarily hepatic, with a half‑life of 6–9 hours in healthy adults; metabolites are excreted in urine and feces.

Conditions Treated with Grifulvin V

• Tinea corporis (ringworm of the body) – widespread lesions on the trunk or limbs that do not respond to topical agents.
• Tinea cruris (jock itch) – fungal infection of the groin and inner thigh region, often chronic in humid climates such as Hong Kong.
• Tinea pedis (athlete’s foot) – persistent interdigital infection, especially in individuals who wear occlusive footwear.
• Tinea capitis (scalp ringworm) – common in children; oral therapy is required because the fungus resides within hair follicles.
• Onychomycosis (fungal nail infection) – long‑term infection of toenails or fingernails, where systemic therapy reaches the nail plate.

These conditions are prevalent in Hong Kong due to the subtropical climate, high population density, and frequent use of communal showers and public pools. Grifulvin V’s ability to accumulate in keratinized tissue makes it particularly effective for these dermatophyte infections.

Who is Grifulvin V For?

• Patients with extensive or recurrent dermatophyte infections that have failed topical therapy.
• Children older than 6 years with scalp infection (tinea capitis) where rapid resolution is needed to prevent alopecia.
• Adults with onychomycosis involving more than one nail or a nail matrix infection, where topical agents cannot penetrate adequately.
• Individuals with immunocompromised conditions (e.g., diabetes, HIV) who are at higher risk of deep‑seated fungal infections.

Grifulvin V is not recommended for:

• Patients with known hypersensitivity to Griseofulvin or any tablet excipients.
• Pregnant or breastfeeding women, because Griseofulvin crosses the placenta and is excreted in breast milk.
• Patients with severe hepatic impairment, as metabolism is reduced and toxicity may increase.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset – nausea, vomiting, abdominal cramps, and loss of appetite are reported in up to 20 % of users.
• Headache – mild to moderate headache occurs in roughly 10 % of patients.
• Photosensitivity – increased skin sensitivity to sunlight; patients may develop erythema after brief UV exposure.

Rare

• Hepatic enzyme elevation – mild, transient increases in alanine aminotransferase (ALT) and aspartate aminotransferase (AST).
• Hematologic changes – occasional leukopenia or thrombocytopenia, usually reversible after discontinuation.
• Peripheral neuropathy – tingling or numbness in extremities reported in isolated cases.

Serious

• Severe hepatic injury – rare cases of hepatitis and cholestasis have been documented; patients should seek immediate medical attention if jaundice or dark urine develops.
• Severe cutaneous reactions – Stevens‑Johnson syndrome or toxic epidermal necrolysis, though extremely uncommon, require urgent care.
• Bone marrow suppression – pancytopenia has been described in prolonged high‑dose therapy; routine blood counts are advised for long‑term treatment.

Drug–Drug Interactions

• Cytochrome P450 inducers (e.g., rifampicin, phenobarbital, carbamazepine) reduce Griseofulvin plasma levels, potentially compromising efficacy.
• CYP450 inhibitors (e.g., erythromycin, fluconazole) may increase Griseofulvin concentrations, raising the risk of toxicity.
• Oral contraceptives – Griseofulvin may decrease hormonal contraceptive effectiveness; additional non‑hormonal contraception is recommended.
• Warfarin – increased anticoagulant effect has been observed; INR monitoring is advised when both drugs are co‑administered.

Patients should disclose all prescription, over‑the‑counter, and herbal products before initiating Grifulvin V.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing:

  • Adults with tinea corporis, cruris, or pedis: 500 mg orally once daily for 2–4 weeks.
  • Children (6–12 years) with tinea capitis: 250 mg once daily (or 12 mg/kg) for 6–8 weeks.
  • Onychomycosis: 500 mg once daily for 6–12 months, depending on nail growth rate.

• Administration: Take the tablet with a full glass of water after a fatty meal to improve absorption; avoid taking antacids or high‑calcium foods within 2 hours of the dose.

• Missed dose: If a dose is missed for less than 12 hours, take it as soon as remembered. If more than 12 hours have passed, skip the missed dose and resume the regular schedule. Do not double‑dose.

• Overdose: Symptoms may include severe nausea, vomiting, dizziness, and liver dysfunction. Seek immediate medical attention; treatment is supportive, focusing on gastric decontamination and monitoring hepatic function.

• Precautions:

  • Limit exposure to direct sunlight; wear protective clothing and sunscreen (SPF 30 or higher).
  • Avoid alcohol, which can exacerbate hepatic side effects.
  • Patients with chronic liver disease should undergo baseline liver function tests and periodic monitoring.

FAQ

• Is Grifulvin V approved for use in children under six years old?
  Grifulvin V is not recommended for children younger than six years because safety and efficacy data are limited in this age group. Alternative topical treatments are usually preferred for younger children.

• Can I travel internationally with Grifulvin V tablets?
  Yes, you may travel with the medication, but keep the tablets in their original packaging with a copy of the prescription (if required) and a letter from a physician confirming medical necessity. Some countries may require declaration at customs.

• Does the tablet contain lactose or gluten?
  The inactive ingredients typically include lactose monohydrate, microcrystalline cellulose, and magnesium stearate. Patients with severe lactose intolerance or celiac disease should verify the exact formulation with the supplier before use.

• How should Grifulvin V be stored in Hong Kong’s humid climate?
  Store the tablets at a controlled room temperature of 20–25 °C, protected from moisture, heat, and direct sunlight. Use a sealed container or original blister pack to guard against humidity, which can degrade the drug over time.

• Will Grifulvin V affect my blood test results for drug screening?
  Griseofulvin is not a substance typically screened for in standard occupational drug tests. However, it may appear as a foreign compound in specialized toxicology panels; informing the testing laboratory can prevent misinterpretation.

• Are there differences between Grifulvin V manufactured in Europe versus Asia?
  Formulations may vary in excipients such as fillers or binders, but the active ingredient (Griseofulvin) remains identical. Regulatory agencies in each region require bioequivalence, ensuring comparable therapeutic effect.

• What is the typical time to see clinical improvement after starting therapy?
  Visible reduction in erythema and scaling usually occurs within 2–3 weeks for skin infections, while nail clearance may take several months because the drug acts on newly grown nail tissue.

• Can Grifulvin V be taken with antacids containing aluminum or magnesium?
  Antacids can reduce the absorption of Griseofulvin. It is advisable to separate the dosing interval by at least two hours to maintain adequate drug levels.

• Is there a generic version of Grifulvin V that costs less?
  Yes, multiple manufacturers produce generic Griseofulvin tablets that are therapeutically equivalent. Our online pharmacy offers these generic alternatives at a lower price point while maintaining the same dosage strength.

• What should I do if I develop a rash while on Grifulvin V?
  A mild rash may be a benign skin reaction, but if it spreads, is accompanied by fever, or involves mucous membranes, discontinue the medication and seek urgent medical evaluation for possible severe cutaneous adverse reaction.
