A 19-year-old woman with moderate inflammatory acne not responding to topical treatment, who uses a contraceptive patch. Which is the most appropriate second-line treatment?

• A. Erythromycin tablets
• B. Oxytetracycline tablets
• C. Doxycycline tablets
• D. Isotretinoin tablets

Answer: (B)

When moderate inflammatory acne doesn’t respond to topical therapy, a systemic antibiotic is often added. In a young woman using a contraceptive patch, safety in relation to pregnancy prevention is a key factor, because some acne medicines carry teratogenic risks or require special pregnancy-control programs. Isotretinoin is powerful and can cause severe birth defects; it requires strict pregnancy prevention and monitoring, so it’s not a suitable second-line choice here. Erythromycin could be used, but tetracyclines tend to have better efficacy for inflammatory acne. Doxycycline is commonly effective, but it is contraindicated in pregnancy and is usually avoided in women who could become pregnant because of potential fetal risks if pregnancy occurs, even with reliable contraception. Oxytetracycline is another tetracycline option with good activity against inflammatory acne. In a patient who could become pregnant and is using hormonal contraception, oxytetracycline provides effective acne control while avoiding the more stringent pregnancy precautions associated with isotretinoin and the higher teratogenic concerns linked to doxycycline. This balance makes it the most appropriate second-line choice among the given options.
