Griseofulvin 500mg Dosage for Adults

For adults, a common dosage of griseofulvin is 500mg per day, taken once or twice daily [1]. This dosage is typically prescribed for a duration of two to six weeks, depending on the specific fungal infection being treated [1]. The length of treatment can vary, with some infections requiring up to eight weeks of medication [2].

How Long Should Griseofulvin Be Taken?

The duration of griseofulvin treatment is determined by the severity and location of the fungal infection. For example, infections of the skin and hair generally require two to four weeks of treatment, while infections of the nails can necessitate treatment for up to eight weeks [2]. It is crucial to complete the full course of medication as prescribed by a healthcare professional, even if symptoms improve earlier [3].

What Does Griseofulvin Treat?

Griseofulvin is an antifungal medication used to treat various fungal infections of the skin, hair, and nails [3]. It is particularly effective against dermatophytes, which are fungi that cause conditions such as ringworm (tinea corporis), athlete's foot (tinea pedis), jock itch (tinea cruris), and infections of the scalp (tinea capitis) and nails (onychomycosis) [4]. The medication works by binding to fungal microtubules, disrupting mitosis, and thus inhibiting fungal cell division [5].
