Answer

Subantimicrobial therapy or concurrent treatment with topical benzoyl peroxide may reduce the emergence of resistant strains. [42] Comparing subantimicrobial 40-mg doxycycline, 100-mg doxycycline, and placebo, Moore et al found a comparable percentage of patients clear of acne between at the 40-mg and 100-mg doses, both significantly higher than placebo. [43] Additionally, less drug-related adverse events were found with the 40-mg subantimicrobial dosing. Enteric-coated, delayed-release formulations of doxycycline can further reduce gastrointestinal adverse effects. [44]
