Canadian healthcare practitioners may also consider it for off-label uses, such as treating chronic fungal infections affecting the skin and nails when conventional therapies prove ineffective.

• Tinea capitis
• Tinea corporis
• Tinea unguium
• Tinea pedis

Healthcare providers stress the importance of adhering to established dosing regimens to maximize treatment effectiveness and minimize the chances of recurrence. Accurate dosing ensures that patients receive optimal care while addressing their specific infections.

Composition & Brand Landscape

Griseofulvin is commercially available in several formulations, including tablets, capsules, and suspensions. The most prominent Canadian brand names include Gris-PEG and Grisactin, although several international brands may offer varying formulations or packaging styles.
