About Grifulvin
Generic Grifulvin (Griseofulvin) is a prescription-only oral antifungal medication used to treat a range of dermatophyte infections of the skin, hair, and nails. The single-ingredient formulation contains 250 mg of griseofulvin per pill, a drug that belongs to the benzothioxan-trione class. In Australia the product is listed on the Therapeutic Goods Administration (TGA) register and is indicated for conditions such as tinea corporis, capitis, and tinea barbae. Although griseofulvin has been available for decades, it remains a valuable option when newer agents are unsuitable or when cost considerations favour a well-established generic therapy.
What is Generic Grifulvin (Griseofulvin)?
Generic Grifulvin (Griseofulvin) contains the active compound griseofulvin, a fungal-cell-wall synthesis inhibitor first approved in the 1950s. In Australia the drug is scheduled as a prescription-only medicine (S4) and is supplied in 250 mg oral tablets. It is marketed by several manufacturers, but the generic version is bioequivalent to brand-name products such as Gris- and Oravig (when formulated for topical use). The TGA classifies it under the “antifungal - systemic” therapeutic group, and the Australian Medicines Handbook lists it as a first-line oral option for certain dermatophyte infections, particularly in children and in infections involving the scalp.
How Grifulvin Works
Griseofulvin exerts its antifungal effect by binding to fungal microtubules, thereby disrupting mitotic spindle formation. This interference blocks cell division, leading to a gradual decline in fungal growth rather than immediate killing. The drug is selective for fungal tubulin; human cells are largely unaffected, which accounts for its relatively safe profile at therapeutic doses. After oral ingestion, griseofulvin is absorbed best with a fatty meal, reaching peak plasma concentrations in 2-3 hours. It is highly protein-bound (≈ 85 %) and distributes preferentially into keratinous tissues-skin, hair, and nails-where dermatophytes reside. Metabolism occurs primarily via hepatic cytochrome P450 enzymes (CYP2C9, CYP3A4), producing inactive metabolites excreted in bile and urine. The half-life averages 6-8 hours but can extend in patients with hepatic impairment, necessitating dosage adjustments.
Why Grifulvin is Used for Fungal Infections
- Targeting dermatophytes - Griseofulvin’s affinity for keratin-rich tissues concentrates the drug where dermatophytes colonise, making it especially effective for scalp (tinea capitis) and body (tinea corporis) infections.
- First-line for children - Clinical trials in paediatric populations demonstrated cure rates of 80-90 % for tinea capitis, supporting guideline recommendations that favour griseofulvin over newer agents that lack paediatric safety data.
- Cost-effectiveness - Generic versions are priced substantially lower than newer oral azoles such as terbinafine, providing a financially accessible option for long-duration therapy (often 4-8 ).
- Safety in pregnancy - While not the first choice, the FDA classifies griseofulvin as Category B (US) and Australian data suggest a relatively low teratogenic risk, allowing use when benefits outweigh potential harm.
- Resistance profile - Griseofulvin resistance remains uncommon in most dermatophyte species, unlike some azoles where resistance has risen in certain regions.
Is Grifulvin Right for You?
Grifulvin is most appropriate for patients with confirmed dermatophyte infections that involve the scalp, body skin, or nails, especially when the organism is known to be susceptible. Ideal candidates include children with tinea capitis, adults with extensive tinea corporis, and individuals who cannot tolerate newer azoles due to drug-drug interactions. The medication should be used cautiously in patients with hepatic impairment, as metabolism may be slowed, and in those taking drugs that induce or inhibit CYP2C9/CYP3A4 (e.g., warfarin, certain anticonvulsants). Pregnant women should discuss risks with their prescriber; the drug crosses the placenta but large registries have not identified a clear signal of fetal harm. As always, the decision to initiate therapy rests on a thorough clinical assessment and, when available, laboratory confirmation of the fungal species.
Taking Grifulvin Effectively
- Timing with food - Swallow each 250 mg tablet with a full meal that contains some fat (e.g., dairy or oil) to maximise absorption.
- Adherence - Dosage is typically 500 mg twice daily for children over 10 kg and 100 mg once daily for adults, but the exact schedule should follow the prescriber’s instructions. Skipping doses can prolong treatment and increase the risk of relapse.
- Missed dose - If a dose is missed by less than 12 hours, take it as soon as remembered; otherwise skip and resume the regular schedule, avoiding double-dosing.
- Travel considerations - Carry a supply that covers the full prescribed course; griseofulvin remains stable at room temperature for up to two years.
- Interaction watch - Avoid concurrent use of oral contraceptives without additional barrier methods, as griseofulvin can reduce estrogen efficacy. Report any new medications, especially anticoagulants, to your healthcare provider.
Understanding Side Effects and How to Manage Them
Because griseofulvin concentrates in keratinous tissue, many adverse effects are related to its impact on cell turnover and hepatic metabolism.
- Common, mild reactions - Headache, gastrointestinal discomfort, and photosensitivity occur in up to 20 % of users. Managing these includes taking the tablet with food, staying hydrated, and using sunscreen or protective clothing when outdoors.
- Hepatic concerns - Elevated liver enzymes can appear after several weeks of therapy. Routine blood tests are advisable for patients on prolonged courses; if transaminases rise more than threefold, discontinuation may be necessary.
- Hematologic effects - Rarely, griseofulvin induces leukopenia or thrombocytopen reporting of unexplained bruising, fever, or persistent sore throat is essential.
- Severe reactions - Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported, though extremely uncommon. Immediate medical attention is required if a widespread rash, blistering, or mucosal involvement develops.

Frequently Asked Questions
-
What is the typical duration of treatment with Grifulvin? Therapy usually lasts 4-8 weeks for skin infections and up to 6 months for scalp involvement, depending on clinical response and follow-up cultures.
-
Can I take Grifulvin with alcohol? Moderate alcohol consumption does not significantly affect absorption, but excessive intake may increase liver strain, so it is advisable to limit intake while on therapy.
-
Is Grifulvin safe for people with diabetes? The medication does not directly influence blood glucose; however, any liver-related side effects could alter drug metabolism, so monitoring is prudent.
-
How does Grifulvin compare to terbinafine for nail infections? Terbinafine achieves higher concentrations in nail tissue and often yields faster cure rates for onychomycosis. Griseofulvin is generally reserved for cases where terbinafine is contraindicated or unavailable.
-
Do I need to continue using topical antifungals while taking Grifulvin? Adjunctive topical therapy can reduce fungal load and hasten symptom relief, especially for extensive skin involvement; discuss combined use with your prescriber.
-
Will Grifulvin affect my birth control pills? Yes, it may decrease estrogen efficacy. Using a non-hormonal barrier method or an additional contraceptive is recommended during treatment.
-
Are there natural alternatives to Grifulvin? Some botanical extracts (e.g., tea tree oil) exhibit antifungal activity, but clinical limited and they are not substitutes for prescription therapy in confirmed dermatophyte infections.
-
What should I do if I miss a dose for more than 24 hours? Contact your healthcare provider for guidance; restarting the regimen without professional advice may lead to sub-therapeutic exposure.
-
Can Grifulvin be used for fungal infections of the internal organs? No, its distribution is confined to keratinous tissues; systemic mycoses require agents with broader tissue penetration such as fluconazole or amphotericin B.
-
Is it necessary to have liver function tests before starting Grifulvin? Baseline liver enzymes are recommended, especially for patients with known hepatic disease or those on concomitant hepatotoxic drugs.
