Griseofulvin is an oral antifungal doctors prescribe for skin, hair, and nail fungal infections. If you’re thinking about buying it online, start by knowing how it works, what side effects to watch for, and how to spot a trustworthy seller. This page gives clear, practical tips so you can make a safer choice.
Griseofulvin stops fungus by interfering with fungal cell division. Clinically it’s used for dermatophyte infections like tinea corporis (ringworm), tinea capitis (scalp), and some nail infections. Treatment often lasts weeks to months — for example, tinea capitis commonly needs 6–8 weeks, sometimes longer. Take it exactly as your clinician prescribes and keep follow-up visits to confirm the infection is clearing.
There are two main forms: microsize and ultramicrosize. Ultramicrosize is more easily absorbed, so dosing can differ between the two. Your prescriber will pick the right form and dose for your age, weight, and infection type.
Common side effects include stomach upset, headache, dizziness, and skin sensitivity to sunlight. More serious risks include liver problems and blood changes. Don’t take griseofulvin if you’re pregnant or planning to get pregnant — it can cause birth defects. Also avoid if you have severe liver disease.
Important drug interactions: griseofulvin can reduce the effectiveness of hormonal birth control and can interact with blood thinners like warfarin and some anticonvulsants. Tell your prescriber about all medicines, supplements, and herbs you take. Taking the tablet with a fatty meal or milk can improve absorption, but follow your prescriber's instructions.
Only buy from licensed pharmacies. Look for clear contact info, verified pharmacy seals, and a requirement to upload a prescription. If a site sells griseofulvin without asking for a prescription, that’s a red flag. Check reviews and avoid sites that offer very low prices with no pharmacist access.
When the package arrives, inspect the box for proper labeling, expiration date, and intact seals. If pills look different than expected or packaging is damaged, don’t take them — return them and report the seller.
If cost is a concern, ask your prescriber about generic options and check legitimate discount programs or local pharmacy pricing. Never compromise safety for a cheaper price.
If you’re unsure whether griseofulvin is right for your infection, get a proper diagnosis first. A short clinic visit or telehealth consult can save time and keep you safe. If you already have a prescription, use the safety checklist above before buying online.
