Griseofulvin ultramicrosize?

Griseofulvin ultramicrosize is an oral antifungal medicine in which the griseofulvin particles are ultramicronized to improve absorption. It’s used to treat dermatophyte infections of the skin, hair, and nails (for example tinea corporis, tinea cruris, tinea capitis, and onychomycosis). It works best against dermatophytes and is not effective for Candida infections.

Key points
- Absorption: improved versus older, larger-particle formulations; absorption is enhanced when taken with fatty meals (a typical instruction is to take with a meal or snack that contains fat).
- Dosing: highly age/weight dependent and should be prescribed by a clinician. Common general patterns (under a clinician’s supervision) are:
- Tinea capitis (scalp): about 20–25 mg/kg per day, in divided doses, for several weeks (often 6–12 weeks).
- Other skin dermatophytes (tinea corporis/cruris): about 10–20 mg/kg per day for several weeks.
- Nail (onychomycosis) infections: regimens tend to be longer (months) and may use higher daily doses; exact dose and duration are individualized.
- Duration: skin infections usually weeks; nail infections typically months because nails grow slowly.
- Side effects and monitoring: can cause GI upset, headaches, tiredness, and photosensitivity; may affect liver function. Because it induces liver enzymes, it can interact with many drugs and can reduce effectiveness of oral contraceptives and warfarin. Baseline and periodic liver function tests are often recommended.
- Contraindications: avoid in pregnancy (teratogenic risk) and in porphyria; use with caution in liver disease.
- Practical notes: discuss all medications and pregnancy plans with a clinician. Do not self-initiate or adjust dose without professional advice.

If you tell me your country/region and what infection you’re treating (e.g., tinea capitis vs. nail infection) I can give you more specific, label-aligned dosing information and emphasize safety considerations.
