DR1.2 | Acne Management Planning — Summary & Reflection

KEY TAKEAWAYS

Acne management is severity-matched step therapy built on the four pathogenetic pillars. Mild acne is treated with topical therapy alone — a topical retinoid ± benzoyl peroxide (BPO), with azelaic acid especially useful in Indian skin for its triple anti-comedonal, antimicrobial, and anti-pigmentary action. Moderate acne adds an oral antibiotic (a tetracycline such as doxycycline) for ≤3 months, ALWAYS with BPO and NEVER as monotherapy, to limit C. acnes resistance. Severe nodulocystic, scarring, or refractory acne is the indication for oral isotretinoin (0.5–1 mg/kg/day to a cumulative ≈120–150 mg/kg — confirm against current guidance), which is absolutely contraindicated in pregnancy and demands mandatory pregnancy prevention, LFT and lipid monitoring, and must NOT be combined with a tetracycline (intracranial hypertension risk). Women with a hormonal pattern (PCOS, jaw-line acne, premenstrual flares) benefit from combined oral contraceptives or spironolactone. When a plan fails, check adherence, the diagnosis (mimics like rosacea lack comedones), antibiotic resistance, and hyperandrogenism before escalating. A rational, safe, individualised plan — matched to grade and counselled to the patient — prevents both scarring and drug harm.

REFLECT

Imagine the two patients from the start of this module are now sitting in front of you and you must write each a plan. For the boy with mild comedonal acne and the girl with severe scarring nodulocystic acne, what would you prescribe for each, and how would your safety counselling differ — particularly for a young woman who might one day become pregnant? Reflect on a tension you will repeatedly face in practice: the most effective drug (isotretinoin) is also the most dangerous, and the most over-used (antibiotics) quietly drives resistance. How will you balance a distressed, scarring patient's urgent need against the discipline of an adequate conventional trial and rigorous safety steps? Consider, too, how clearly explaining the plan, the timeline, and the reasons behind each safety rule turns a prescription into a partnership that the patient will actually follow.
