does erythromycin-benzoyl peroxide gel work
1 Benzoyl peroxide/erythromycin gel works best if used at the same time(s) each day.  If you miss a dose of benzoyl peroxide/erythromycin gel, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
