Dapsone gel vs azelaic acid for acne
Every row cites its source. Where a cell reflects our own reading of the evidence rather than an external source, the row says so.
Two gentle prescription topicals, honestly compared. Our sister site covers azelaic acid in the same depth as this page covers dapsone; the azelaic numbers here are the same numbers that site reports.
| Aspect | Dapsone gel | Azelaic acid (15% / 20%) | Source |
|---|---|---|---|
| Approved scope | Acne only (topical); the molecule's other approvals are oral, for different diseases | Acne (20% cream) plus rosacea (15% gel/foam) | source |
| 2024 AAD guideline position | Not named in the abstract's strong or conditional lists | Conditional recommendation, by name | source |
| Best benchmark trial | Vehicle-controlled only: about 8 to 10 GAAS points over vehicle; about 2 lesions of separation on absolute counts | Matched benzoyl peroxide 5% head-to-head: 70% median inflamed-lesion reduction, 351 patients, 4 months | source |
| Head-to-head vs each other | Never tested: zero randomized trials of dapsone vs azelaic acid | Same absence, stated identically on both sites | source |
| Irritation profile | Nearly vehicle-identical in trials; postmarketing rarities are hematologic, not cutaneous | Burning and stinging in about 29% with the 15% gel (its own label number, reported on the sister site); less irritating than BPO in trials | source |
| Blood considerations | G6PD story (lab-only changes; no testing required since 2008); methemoglobinemia case reports | None: azelaic acid is a dietary-constituent dicarboxylic acid with about 4% absorption | source |
