Topical adapalene with benzoyl peroxide, plus an oral antibiotic (see below).

Topical azelaic acid, plus an oral antibiotic (see below).
Oral doxycycline is the preferred antibiotic. Lymecycline should only be used if there are issues with doxycycline (e.g. photosensitivity). Erythromycin can be used if contraindications/intolerances to tetracyclines.
For females in the treatment of moderate to severe acne, vulgaris if the chosen first-line treatment is not effective, consider adding co-cyprindiol or an alternative combined oral contraceptive pill.
Spironolactone can be considered in moderate to severe acne vulgaris in women who have failed to respond/not tolerate one topical and one systemic agent as above. It can be used as monotherapy or in addition to the options above.
Prescribing Notes:
- Do not use systemic monotherapy with a topical antibiotic, monotherapy with an oral antibiotic or topical and oral antibiotics in combination.
- Evidence suggests there is limited clinical benefit in using antibiotics for >3 months.
- Prolonged antibiotic exposure increases risk of resistance in pathogenic bacteria.
- Antibiotics should not be continued beyond 6 months unless in exceptional circumstances on advice of dermatologist.
- Tetracyclines and retinoids (systemic or topical) must be avoided in pregnancy. Females of childbearing age must use effective contraception when using topical retinoids and related drugs including: adapalene, trifarotene, and Treclin gel.
- Co-cyprindiol is a treatment for moderate to severe acne vulgaris where other treatments have failed and only in those patients may it also be used as an oral contraceptive. Co-cyprindiol should be withdrawn 3-4 cycles after the treated condition has completely resolved. If ongoing contraception is required, substitution with another combined oral contraceptive is likely to maintain the improvement.
