Fulcin is the well-known international brand name for griseofulvin, a systemic antifungal medicine widely used for dermatophyte infections. In the United States, griseofulvin has been available for decades and remains an important treatment option, especially for scalp ringworm (tinea capitis) in children and adults who cannot use alternative therapies. Fulcin tablets are commonly supplied in 125 mg, 250 mg, and 500 mg strengths. Two formulations exist—microsize and ultramicrosize—which differ in absorption and dosing; your clinician will prescribe the appropriate form and dose based on your age, weight, and specific infection.

As a prescription medication in the USA, Fulcin must be used under medical supervision. Licensed healthcare providers may prescribe griseofulvin after confirming a dermatophyte infection. Many patients choose the convenience of telemedicine for evaluation, diagnosis confirmation, and prescription issuance, followed by delivery from a reputable U.S. pharmacy. When used correctly, Fulcin is effective for tinea capitis and other ringworm infections, helps resolve symptoms, and prevents recurrence when paired with appropriate hygiene and environmental measures. This page explains how griseofulvin works, who it is for, how to take it safely, potential side effects, and how to arrange a legitimate online purchase within the United States.

Fulcin price in the USA

Griseofulvin is available as a brand or generic, with generics typically offering substantial savings. U.S. pricing varies by strength, formulation (microsize vs. ultramicrosize), manufacturer, pharmacy discount programs, and insurance coverage. Many pharmacies participate in savings plans that reduce out-of-pocket costs for common antifungals. If you have insurance, check your plan’s formulary and preferred pharmacies for the most favorable copay.

As a general orientation, lower strengths such as 125 mg or 250 mg generic griseofulvin often have the lowest per-tablet cost, while higher-strength or specialty formulations may be priced higher. A larger quantity can reduce the unit cost when long courses are prescribed—common with scalp and nail infections that require extended treatment. Because prices change frequently in the U.S. market, we recommend checking our partner’s live pricing after your prescriber selects the exact strength and formulation. You can also compare local retail pharmacies to choose the best option for your budget.

If multiple family members require treatment (for example, in a household outbreak of tinea capitis), ask your clinician about coordinated prescriptions and whether combination approaches (oral plus topical agents) may shorten duration or improve outcomes. Using prescription savings cards, manufacturer coupons when available, and pharmacy membership programs can further reduce the total expense.

Where can I buy Fulcin in the USA?

 In the United States, griseofulvin (Fulcin) is a prescription-only medication. That means you will need a valid prescription from a licensed U.S. healthcare provider before the pharmacy can dispense the medicine. Most patients obtain Fulcin through one of the following routes:

- In-office visit: Your primary care clinician, pediatrician, or dermatologist evaluates your symptoms, may perform a simple exam with or without a fungal culture, and sends the prescription to your preferred pharmacy.
- Telehealth evaluation: For many straightforward cases, a virtual visit is sufficient for diagnosis and prescribing. After a brief assessment and medical review, the clinician can electronically send your griseofulvin prescription to a mail-order or local pharmacy.

Our partner platform helps streamline this process by connecting you with licensed clinicians where available and coordinating direct delivery from a U.S.-based pharmacy. Orders are shipped discreetly, and customer service is available to track deliveries and answer practical questions about refills, storage, and returns.

We have served patients across the USA for years and support secure online checkout, transparent pricing, and fast order processing. If your local pharmacy runs out of your prescribed strength, we can help locate an alternative fulfillment option so you can continue treatment without interruption.

Fulcin (griseofulvin) in the USA

Griseofulvin remains a first-line therapy for tinea capitis in many U.S. pediatric and adult guidelines. It is also prescribed for other dermatophyte infections—especially when disease is widespread, inflammatory, or unresponsive to topical treatment alone. While newer antifungals such as terbinafine and itraconazole are commonly used for certain conditions (e.g., onychomycosis), griseofulvin can still be appropriate where alternatives are unsuitable, contraindicated, or not tolerated. Your clinician will select the best agent based on the infection site, severity, patient-specific factors, and local susceptibility patterns.

What is Fulcin (griseofulvin)?

 Fulcin is the trade name for griseofulvin, an antifungal agent produced by species of Penicillium. It is fungistatic against dermatophytes, meaning it prevents fungal growth and spread rather than directly killing the organisms outright. Griseofulvin concentrates in keratin precursor cells in skin, hair, and nails, protecting new keratin from fungal invasion as it grows. Over time, infected tissue is replaced by healthy tissue, which leads to resolution of infection with consistent use.

Fulcin is indicated specifically for dermatophyte infections caused by Trichophyton, Microsporum, and Epidermophyton species. It is not effective against Candida (yeast), Malassezia (tinea versicolor), or most bacterial infections, and it is not used for scabies or head lice. Because accurate diagnosis improves outcomes, your clinician may use clinical appearance, dermatoscopic clues, and occasionally lab tests (KOH preparation, fungal culture) to confirm that griseofulvin is the right choice for your condition.

Common infections treated with griseofulvin include tinea capitis (scalp ringworm), tinea corporis (ringworm on the body), tinea cruris (jock itch), tinea pedis (athlete’s foot), and certain nail infections (tinea unguium/onychomycosis) when alternatives are unsuitable. Duration of therapy depends on the site: scalp and nails often require longer courses than groin or body infections.

Fulcin for tinea capitis (scalp ringworm)

 Tinea capitis is a contagious fungal infection of the scalp and hair shafts, common in school-age children but also seen in adults. Symptoms include scaly patches, broken hairs, pruritus (itching), and occasionally swollen lymph nodes in the neck. Inflammatory forms may present with tender plaques (kerion) and can cause temporary hair loss.

Because topical agents cannot adequately penetrate the hair follicles, tinea capitis requires systemic therapy. Griseofulvin is a well-established option, with extensive safety and efficacy data in children. It is often combined with adjunctive measures such as a 2% ketoconazole or 1–2.5% selenium sulfide shampoo used several times per week to reduce surface fungal burden and the risk of transmission. Household contacts may be asked to use antifungal shampoo as a preventive measure, especially during outbreaks.

Typical treatment lasts 6–12 weeks, continuing at least 2 weeks beyond clinical resolution. Your clinician will choose a microsize or ultramicrosize formulation and dose it based on weight and age to optimize absorption and outcomes.

Why Fulcin still matters for scalp infections

Although newer oral antifungals exist, griseofulvin’s long record of use, pediatric dosing familiarity, and effectiveness against many Microsporum species make it a mainstay for tinea capitis in the USA. It can be especially helpful in inflammatory cases and when culture suggests species for which griseofulvin performs well. When taken daily with a fatty meal or milk to enhance absorption, the likelihood of treatment success increases. Adherence to the full course is key to preventing relapse.

How Fulcin works (mechanism and pharmacology)

 Griseofulvin interferes with fungal cell division by binding to fungal microtubules and disrupting the mitotic spindle. It also becomes concentrated in keratin precursor cells, making newly formed keratin in hair, skin, and nails resistant to dermatophyte invasion. This dual action both halts fungal replication and protects new tissue as it grows out.

The drug is better absorbed when taken with fatty food, and the ultramicrosize formulation has higher bioavailability than microsize at the same milligram dose. Clinicians account for these differences by adjusting dosing schedules. Because griseofulvin induces certain liver enzymes (CYP), it can interact with other medications—details are provided later in this guide.

Griseofulvin’s spectrum of activity

Fulcin is active against dermatophytes such as Trichophyton, Microsporum, and Epidermophyton. It is not active against yeasts like Candida or against non-dermatophyte molds that sometimes involve nails. For onychomycosis caused by dermatophytes, other agents (e.g., terbinafine) are frequently preferred, but griseofulvin may still be used when alternatives are not appropriate. Culture or diagnostic testing can guide therapy in challenging cases.

Fulcin for tinea corporis and tinea cruris

 Tinea corporis (ringworm of the body) and tinea cruris (jock itch) typically respond to topical antifungals. However, systemic therapy with griseofulvin is considered when the infection is extensive, recurrent, or unresponsive to topical treatment alone. Symptoms include annular lesions with raised scaly borders, itching, and central clearing. In tinea cruris, lesions affect the groin folds and may extend to adjacent areas.

Fulcin is used for 2–4 weeks in many cases, though duration varies with severity, response, and whether other sites (scalp, feet, nails) are also involved. Hygiene measures—keeping the area dry, wearing breathable fabrics, washing gym gear frequently, and avoiding sharing towels—are essential to prevent reinfection.

Fulcin for tinea pedis (athlete’s foot)

 Athlete’s foot most often responds to topical treatment, but oral griseofulvin may be prescribed for chronic moccasin-type tinea pedis, extensive disease, or cases that do not improve with topicals. Improvements usually appear within a few weeks, but complete resolution and prevention of recurrence require diligent foot care, including drying between toes, rotating shoes to allow them to air out, and using antifungal powders if prone to sweating.

Because tinea pedis can serve as a reservoir for reinfection of nails or groin, treating the feet thoroughly is important in patients with multi-site disease.

Action

 At the cellular level, griseofulvin inhibits fungal mitosis by disrupting microtubule function and the mitotic spindle. Clinically, it protects new keratinized tissue, allowing healthy hair, skin, and nails to replace infected areas over time. This is why therapy often continues for several weeks to months, depending on the site of infection and the rate of keratin turnover.

Because the medication is fungistatic rather than fungicidal, consistent daily dosing is vital, and clinicians may recommend supportive topical therapy (for example, antifungal shampoos) to decrease surface fungal load and transmission risk.

Safety and monitoring

Griseofulvin has been used by millions of patients and is generally well tolerated. Common adverse effects include headache, gastrointestinal upset, fatigue, and mild skin rashes. Photosensitivity can occur; protecting skin with clothing or sunscreen is recommended during therapy. Rare reactions include serious skin eruptions, blood count abnormalities, and liver enzyme elevations, particularly with prolonged courses.

Baseline and periodic liver function tests (and sometimes complete blood counts) may be recommended for long-duration therapy such as with nail disease. Individuals with significant hepatic impairment, porphyria, or systemic lupus erythematosus should not use griseofulvin. Discuss your full medical history and all medications with your clinician before starting Fulcin.

Fulcin dosage for adults and children

 Dosing depends on formulation, body weight, and infection site. Always follow your prescriber’s instructions and the pharmacy label. General reference ranges include:

- Microsize formulation: typically 10–20 mg/kg/day in a single daily dose or divided doses; adults often require 500–1000 mg/day depending on severity.
- Ultramicrosize formulation: typically 5–10 mg/kg/day; adults commonly use 375–750 mg/day.

Take Fulcin with a fatty meal or milk to enhance absorption. For children, dosing is weight-based and adjusted as they grow. If you miss a dose, take it when remembered unless it’s close to the next scheduled dose—do not double up. Courses typically run:

• Tinea capitis: usually 6–12 weeks, or at least 2 weeks after symptoms resolve
  
• Tinea corporis/cruris: generally 2–4 weeks, longer if extensive
  
• Tinea pedis: often 4–8 weeks for systemic therapy when indicated
  
• Tinea unguium (onychomycosis): several months if used; alternatives are commonly preferred

Typical duration of therapy by infection

 Your clinician will tailor duration to your response. In general, continue griseofulvin until clear clinical improvement plus an additional 1–2 weeks to reduce relapse risk. Because nails and hair grow slowly, patience and adherence are critical. To improve outcomes, pair systemic therapy with appropriate topicals and environmental control (e.g., disinfect hair tools, avoid sharing hats and combs, treat pets if a veterinary source is suspected).

Use the upper end of dosage ranges or extended durations when infections are extensive, inflammatory (e.g., kerion), or slow to respond, or when reinfections occur frequently in the household. Follow-up visits allow your provider to track progress and adjust therapy.

Tinea capitis: dosing and practical tips

For scalp ringworm, pediatric weight-based dosing is standard. Because absorption is improved by dietary fat, giving the dose with milk or a meal is recommended. Inflammatory tinea capitis may require adjunctive measures such as a short course of anti-inflammatory therapy per clinician judgment. Using antifungal shampoo 2–3 times weekly helps limit surface transmission. Replace or disinfect hair accessories and consider screening household contacts if frequent reinfection occurs.

Onychomycosis (tinea unguium): role of griseofulvin

Although Fulcin can be used for dermatophyte nail infections, many U.S. guidelines prefer other oral antifungals (such as terbinafine) for onychomycosis due to higher cure rates and shorter courses. Griseofulvin may still be considered when alternatives are contraindicated, not tolerated, or unavailable. If prescribed for nails, expect prolonged therapy—often several months—and discuss monitoring with your clinician. Pairing oral therapy with careful nail hygiene, trimming, and sometimes topical agents may improve results.

How to take Fulcin

 Take griseofulvin exactly as prescribed, preferably at the same time each day, with milk or a fatty meal to maximize absorption. Do not stop early unless directed, even if symptoms improve quickly. For tinea capitis, your clinician may recommend shampooing with an antifungal agent several times a week; follow instructions carefully. If gastrointestinal upset occurs, dividing the daily dose can help.

Store Fulcin at room temperature away from excessive heat and moisture. Keep it out of reach of children. If you experience persistent side effects, call your clinician to discuss possible dose adjustments or alternative therapies.

Pregnancy and breastfeeding

Griseofulvin should not be used during pregnancy due to potential risks to the fetus. Women of childbearing potential should use effective contraception during treatment and for at least one month after the last dose. Because griseofulvin can reduce the effectiveness of estrogen-containing contraceptives, a non-hormonal backup method is advised.

Men are generally advised to avoid fathering a child during therapy and for a period after discontinuation (often cited as up to 6 months) due to theoretical risks; discuss individual recommendations with your clinician. For breastfeeding, use caution and consult your healthcare provider to weigh risks and benefits; alternative treatments may be preferred depending on the clinical scenario.

Pharmacist’s tips for taking Fulcin

 Always take griseofulvin with food—ideally a meal that contains fat—because this significantly improves absorption. Protect your skin from excessive sun exposure and consider daily sunscreen while on therapy due to photosensitivity risk. Keep the treatment area clean and dry, wear breathable fabrics, and wash workout gear promptly. Avoid sharing personal items like hairbrushes, hats, towels, or nail tools to prevent reinfection and spread.

For scalp infections, replace or disinfect combs and hair accessories. If your clinician orders lab tests for longer courses, complete them as scheduled. If you’re taking other medicines, vitamins, or herbal products, notify your pharmacist to check for interactions—especially if you use warfarin or hormonal contraceptives.

Safety Precautions

 Do not use Fulcin if you have severe liver disease, porphyria, or systemic lupus erythematosus. Avoid alcohol during therapy due to possible adverse reactions and added liver stress. If you develop a widespread rash, severe skin reaction, unusual bruising, persistent fever, yellowing of the skin or eyes, dark urine, or severe fatigue, stop the medicine and seek medical attention promptly.

Use caution if you have a history of allergy to penicillin derivatives; while true cross-reactivity is rare, griseofulvin is derived from Penicillium species and caution is prudent in patients with significant hypersensitivity histories.

Fulcin side effects

 Most side effects are mild and transient. Commonly reported reactions include headache, nausea, vomiting, diarrhea, fatigue, dizziness, and skin rash. Photosensitivity can lead to sunburn more easily than usual. Less common events include peripheral neuropathy, confusion, or insomnia; these typically resolve after dose adjustment or discontinuation.

Rare but serious adverse effects include severe cutaneous reactions (e.g., erythema multiforme), hematologic abnormalities (leukopenia), and hepatotoxicity. Your clinician may recommend periodic blood tests if you are on prolonged therapy or have underlying conditions.

Possible side effects to watch for

Notify your clinician if you notice any of the following while taking griseofulvin:

• unusual weakness or fatigue
• persistent abdominal pain, loss of appetite, nausea, or vomiting
• headache that does not improve with time
• dizziness or drowsiness affecting daily activities
• rash, hives, severe itching, or photosensitivity reactions
• signs of liver issues such as dark urine, yellowing of skin/eyes
• bruising or bleeding unusual for you

Seek urgent medical attention for severe skin reactions, trouble breathing, facial swelling, or other signs of a serious allergic reaction.

• rapid heartbeat, fainting, or marked drops in blood pressure
• unexplained fever, chills, or sore throat that persist
• visual changes, severe headaches, or confusion

Most patients tolerate Fulcin well when it is taken with food and used exactly as prescribed. Your pharmacist can provide additional strategies to minimize side effects and improve adherence.

• consider taking the dose in the evening if daytime drowsiness occurs
• split the total daily dose if gastrointestinal upset is bothersome
• use sun protection clothing and broad-spectrum sunscreen

Reporting side effects

 If you experience side effects, contact your clinician or pharmacist. In the USA, you can also report medication side effects to FDA MedWatch (www.fda.gov/medwatch) to help improve drug safety information.

Interaction of Fulcin with other medicines

 Griseofulvin can interact with a number of medications. It induces hepatic enzymes, which can reduce the effectiveness of certain drugs. Always tell your prescriber and pharmacist about all prescription medicines, over-the-counter drugs, vitamins, and herbal supplements you take. Notable interactions include:

• oral contraceptives: griseofulvin may reduce effectiveness; use a reliable backup method
  
• warfarin: may reduce anticoagulant effect; monitoring and dose adjustments may be needed
  
• barbiturates (e.g., phenobarbital): can decrease griseofulvin blood levels and effectiveness
  
• cyclosporine: griseofulvin may reduce cyclosporine levels
  
• alcohol: increases risk of adverse effects and may trigger flushing or tachycardia

This list is not exhaustive. Provide a complete medication list to your healthcare team so they can help prevent harmful interactions and optimize your therapy plan.

Recommendations from our specialists

 For suspected dermatophyte infections, especially scalp ringworm in children or adults with widespread disease, seek timely evaluation. Early diagnosis and appropriate therapy shorten the course, reduce the risk of scarring or hair loss, and limit spread within households, schools, and sports teams. If Fulcin (griseofulvin) is prescribed, take it with a fatty meal, use adjunctive topicals as directed, and complete the full course even after visible improvement.

Because griseofulvin is prescription-only in the USA, plan ahead: arrange your clinician visit (in-person or telehealth), confirm the pharmacy has your strength in stock, and set reminders so doses aren’t missed.
