HelloPharmacist Editorial Team Bottom Line
Griseofulvin is a prescription oral antifungal used to treat ringworm infections of the skin, scalp, hair, and nails when topical treatments aren't enough. It must be taken for the full course — sometimes several months — to fully clear the infection. Avoid alcohol during treatment, use reliable contraception if you can become pregnant, and tell your doctor right away about any severe skin reactions or signs of liver trouble.

📖 Griseofulvin: Patient Information Guide

A plain-language walkthrough of Griseofulvin — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for▾

Griseofulvin is an oral antifungal that treats dermatophyte (ringworm-type) fungal infections across several products and formulations. It is used when topical (skin-applied) treatments alone are not adequate.

  • Tinea corporis — ringworm of the body
  • Tinea pedis — athlete's foot
  • Tinea cruris — jock itch (ringworm of the groin and thigh)
  • Tinea barbae — ringworm of the beard area
  • Tinea capitis — ringworm of the scalp
  • Tinea unguium (onychomycosis) — fungal infection of the fingernails or toenails

Griseofulvin does not work against bacterial infections, yeast infections (candidiasis), or other fungal infections such as histoplasmosis, sporotrichosis, tinea versicolor, or cryptococcosis. A confirmed fungal diagnosis — through lab testing such as a KOH preparation, fungal culture, or nail biopsy — should be obtained before starting treatment.

⚙️How it works▾

Griseofulvin stops dermatophyte fungi from multiplying by binding to proteins called microtubules inside fungal cells. Microtubules are essential for cell division (mitosis); when griseofulvin blocks them, the fungus can no longer reproduce and spread. After you take it by mouth, the drug is absorbed and deposits into keratin precursor cells — the building blocks of new skin, hair, and nail tissue — making that new tissue resistant to fungal invasion as it grows in.

Griseofulvin has no effect on bacteria or fungal species outside the dermatophyte group it targets. There have been reports of dermatophyte resistance to griseofulvin, though the clinical importance of this is not fully established.

💊How it's taken▾

Griseofulvin is taken by mouth, once or twice daily depending on the product and the infection being treated. Taking it with a fatty meal — such as one containing milk or other high-fat foods — significantly boosts absorption and is generally recommended. Ultramicrosize Griseofulvin tablets may be swallowed whole or crushed and mixed into a tablespoon of applesauce and swallowed right away. Treatment courses vary considerably by infection site:

  • Tinea capitis (scalp): typically 4 to 6 weeks
  • Tinea corporis (body): typically 2 to 4 weeks
  • Tinea pedis (athlete's foot): typically 4 to 8 weeks
  • Tinea unguium (nails): fingernails at least 4 months; toenails at least 6 months

Always follow your prescriber's instructions and complete the full course — stopping early is very likely to cause the infection to return.

🤒Side effects — in detail▾

The most common side effects with griseofulvin are hypersensitivity (allergic-type) reactions and stomach-related symptoms. Serious reactions have also been reported, though they are less common.

  • Skin rash or hives
  • Nausea, vomiting, or upset stomach
  • Diarrhea
  • Headache
  • Dizziness or fatigue
  • Insomnia
  • Tingling or numbness in the hands and feet (peripheral neuropathy — more likely with longer treatment)
  • Oral thrush (yeast infection in the mouth)

Stop griseofulvin and get medical help right away if you develop severe blistering or peeling skin, signs of jaundice (yellowing of skin or eyes), or signs of a serious allergic reaction like swelling of the face or throat. Rarely, griseofulvin has been linked to low white blood cell counts, liver inflammation, and GI bleeding.

⚠️Warnings & precautions▾
  • Serious skin reactions: Stevens-Johnson syndrome and toxic epidermal necrolysis (severe, potentially life-threatening skin blistering and peeling) have been reported. Stop griseofulvin and seek emergency care immediately if this occurs.
  • Liver damage: Elevated liver enzymes, hepatitis, and jaundice have been reported and can be serious. Your doctor may monitor your liver during treatment.
  • Pregnancy: Griseofulvin is contraindicated in pregnancy. It can cause serious birth defects and embryo toxicity. Cases of conjoined twins and spontaneous abortion have been reported in association with griseofulvin use during pregnancy.
  • Not for prophylaxis: Griseofulvin has not been proven safe or effective for preventing fungal infections — it should only be used to treat a confirmed infection.
  • Low white blood cell count (granulocytopenia): Griseofulvin should be stopped if this occurs. Report any unusual infections, fever, or chills to your doctor promptly.
🔀What it interacts with▾

Griseofulvin affects the way certain other medications are broken down in the body and can change how well they work.

  • Warfarin (blood thinner): Griseofulvin reduces warfarin's anticoagulant effect — dose adjustments may be needed during and after griseofulvin therapy.
  • Estrogen-containing birth control pills: Griseofulvin speeds up estrogen breakdown, making oral contraceptives less effective and potentially causing menstrual irregularities. A backup or alternate form of contraception is recommended.
  • Cyclosporine: Griseofulvin may lower cyclosporine levels in the blood, reducing its immunosuppressive effect.
  • Salicylates (e.g., aspirin): Griseofulvin may reduce salicylate blood levels.
  • Barbiturates (e.g., phenobarbital): These can reduce griseofulvin's blood levels and effectiveness — a griseofulvin dose adjustment may be needed.
  • Alcohol: Drinking alcohol during treatment can cause nausea, vomiting, flushing, rapid heartbeat (tachycardia), and severe low blood pressure — avoid alcohol while taking griseofulvin.

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

📋Before taking it▾
  • Do not take griseofulvin if you have porphyria (a rare metabolic disorder) or hepatocellular failure (severe liver failure).
  • Do not take griseofulvin if you are allergic to it.
  • Do not take griseofulvin if you are pregnant or may become pregnant during treatment — it can cause serious harm to a developing baby.
  • Women of childbearing age should use reliable contraception that does not rely solely on estrogen-containing birth control pills during griseofulvin treatment.
  • Tell your doctor about all medications you take, especially warfarin, cyclosporine, oral contraceptives, barbiturates, and aspirin-type drugs.
  • Griseofulvin is not established as safe or effective for children 2 years of age and younger.
  • Tell your doctor if you have any liver problems — griseofulvin is metabolized by the liver and has been associated with liver injury.
  • Griseofulvin is not approved for preventing fungal infections — only for treating a confirmed infection.
🚑If you take too much▾

There is limited information about what happens with a griseofulvin overdose. If too much is taken, the medication should be stopped and supportive care provided. If you suspect an overdose, contact a poison control center or emergency services right away.

📡Pharmacodynamics — effects in the body▾

Griseofulvin works specifically against dermatophyte fungi by blocking their ability to divide. It binds to microtubular proteins inside fungal cells, which are essential for mitosis (cell division), stopping the fungus from reproducing. It deposits into keratin-forming cells in skin, hair, and nails — the new tissue that grows in becomes highly resistant to fungal invasion. Griseofulvin has no activity against bacteria or non-dermatophyte fungi.

🔬Pharmacokinetics — how your body processes it▾

Absorption of griseofulvin from the gut varies considerably between individuals — estimated to range from 27% to 72% of an oral dose. Taking it with a high-fat meal significantly increases absorption. After being absorbed, griseofulvin is distributed into keratin precursor cells and stays in skin longer than it does in the bloodstream after the drug is stopped. It is metabolized by the liver and has a variable half-life (the time it takes for blood levels to drop by half) of 9 to 24 hours. About 50% of a dose is excreted in urine within 5 days, mostly as metabolites, and about one-third is excreted in stool; a small amount is also excreted in sweat.

Ultramicrosize Griseofulvin is absorbed approximately one and a half times more efficiently than the conventional microsize formulation, which means a lower total dose of the ultramicrosize form may be used. However, there is currently no evidence that this difference leads to meaningful differences in safety or effectiveness between the two formulations.

📦How to store it▾

Store at 20° to 25°C (68° to 77°F) .

🩺 Pharmacist Counseling Corner

Quick, plain-English answers to the questions patients ask most about Griseofulvin — the kind of thing our pharmacy team would talk through with you at the counter.

How long do I have to take griseofulvin? It seems like a really long time. ▾
It really can be — and that's one of the most important things to understand about this medication. Fungal infections of the nails especially can take at least 4 to 6 months to clear because you have to wait for healthy, drug-infused nail tissue to fully grow in and replace the infected nail. Scalp and body ringworm are faster, usually a few weeks to a couple of months. The key is to stick with it even after things look better — stopping early almost always means the infection comes back.
Should I take griseofulvin with food? ▾
Yes, and specifically with a fatty meal if you can. Studies show that eating something high in fat — like a full meal with dairy or meat — dramatically increases how much of the medication your body actually absorbs. Taking it on an empty stomach means you may not get the full benefit. If you're taking the Ultramicrosize Griseofulvin tablets and have trouble swallowing them, you can crush them and mix with a tablespoon of applesauce and swallow that right away.
Can I drink alcohol while on griseofulvin? ▾
It's best to avoid alcohol entirely during treatment. The combination of griseofulvin and alcohol has been reported to cause an unpleasant and potentially dangerous reaction — nausea, vomiting, flushing, a racing heartbeat, and severely low blood pressure. It's not worth the risk while you're on this medication.
Will griseofulvin affect my birth control? ▾
Yes — this is really important to know. Griseofulvin can speed up the breakdown of the estrogen in hormonal birth control pills, making them less effective. This means you could be at a higher risk of an unintended pregnancy while taking griseofulvin. Talk to your doctor or pharmacist about using a reliable backup method of contraception — such as condoms — for the entire time you're on griseofulvin. Also, griseofulvin can cause serious birth defects, so avoiding pregnancy during treatment is a must.
What side effects should I actually call my doctor about versus just wait out? ▾
Mild nausea, headache, or an upset stomach are fairly common and often improve on their own. But you should call your doctor right away — or go to the ER — if you develop blistering or peeling skin, yellowing of your skin or eyes, dark urine, severe stomach pain, swelling of your face or throat, or signs of unusual infections like fever and chills. These can be signs of serious reactions affecting your skin, liver, or blood cells, and griseofulvin may need to be stopped immediately.
I'm taking griseofulvin for a nail infection. Do I need to keep using a topical cream too? ▾
For nail infections (tinea unguium), your prescriber may or may not recommend a topical treatment alongside griseofulvin — it depends on your situation. For athlete's foot (tinea pedis) specifically, topical antifungal therapy is usually recommended at the same time, because athlete's foot can sometimes involve bacteria or yeast that griseofulvin won't treat. Good hygiene practices — like keeping feet clean and dry — also help prevent reinfection. Follow your prescriber's full plan and finish the entire course of griseofulvin.
Is Griseofulvin available over the counter? ▾
Griseofulvin is dispensed by prescription according to its FDA labeling, so it isn't sold over the counter. Your prescriber and pharmacist will determine if it's appropriate for you.
When was Griseofulvin first available? ▾
Griseofulvin has been available in the United States since at least 1962, based on FDA approval history (Drugs@FDA) and product marketing records.
Who makes Griseofulvin? ▾
Griseofulvin is supplied by 12 manufacturers listed in the FDA NDC Directory, including Chartwell RX, LLC., Heritage Pharmaceuticals Inc d/b/a Avet Pharmaceuticals Inc, Sandoz Inc.

How we combine label and product data

HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 9 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.

For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Sandoz Inc is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
