Mechanism & Pharmacology

Simplified explanation (patient-friendly)

Dapsone acts as both an antimycobacterial and a topical dermatological agent. Its primary function is to block the synthesis of folic acid in bacteria, which is essential for their growth and reproduction. By inhibiting this process, dapsone effectively treats conditions such as leprosy and acne. This dual action targets both the infection and the underlying inflammation, providing relief and promoting skin healing.

Clinical terms (Health Canada approved monograph references)

In clinical settings, dapsone’s antimicrobial properties are crucial for treating leprosy in combination with rifampicin and clofazimine. Recent studies endorsed by Health Canada highlight its utility in managing inflammatory skin disorders, specifically dermatitis herpetiformis. This medication is recognised for its efficacy in these conditions, contributing to its ongoing endorsement in Canadian healthcare protocols.

Forms & Dosages Sold

Dapsone is available in various forms and dosages to cater to distinct medical needs.

• Oral tablets: Offered in doses of 25mg, 50mg, and 100mg, primarily for leprosy and dermatitis herpetiformis.
• Topical gel/cream: Prepared in strengths of 5% and 7.5%, typically reserved for acne vulgaris and other skin conditions.

It's essential to be aware of common side effects linked with dapsone, which can include:
- Nausea and loss of appetite
- Headaches
- Rashes and mild anaemia
- Itching, particularly with topical applications
- Minor elevations in liver enzymes for some users.
