Most acne is managed well in general practice, and the common error is reaching for an oral antibiotic alone or a single topical. Guidelines favour combining agents that target different parts of the pathway from the outset.
For mild to moderate acne, start a topical retinoid with benzoyl peroxide, adding a topical antibiotic only within a combination to limit resistance, never as monotherapy. Reserve oral antibiotics for moderate to severe inflammatory disease, pair them with a topical retinoid and benzoyl peroxide, and cap the course at about three to four months.
Set expectations: improvement takes six to eight weeks, and early irritation from a retinoid is manageable by starting on alternate nights with a moisturiser. Consider combined oral contraception or spironolactone in women where hormonal drivers are prominent, and refer early for scarring or treatment-resistant disease.
- Start mild to moderate acne on a topical retinoid plus benzoyl peroxide, not monotherapy.
- Use topical antibiotics only within a combination, to limit resistance.
- Reserve oral antibiotics for moderate to severe disease, with a topical retinoid and benzoyl peroxide, for about three to four months.
- Warn that benefit takes six to eight weeks, and ease retinoid irritation with alternate-night starts and a moisturiser.
Why it matters
Combination topical therapy from the start works better and curbs the antibiotic resistance that single-agent prescribing drives.
