<unk>  or continuous<unk>  combined oral<unk>  pills are a packaging of combined oral<unk>  pills (COCPs) that reduce or eliminate the withdrawal bleeding that would occur once every 28 days in traditionally packaged COCPs. It works by reducing the frequency of the pill-free or placebo days.<unk><unk>  use of COCPs may also be called menstrual suppression, although other<unk>  medications or medication delivery systems<unk>  intrauterine devices--IUDs) may also be used to suppress menses. Any brand of combined oral<unk>  pills can be used in an<unk>  or continuous manner by simply discarding the placebo pills; this is most commonly done with monophasic pills in which all of the pills in a package contain the same fixed dosing of a synthetic estrogen and a progestin in each active pill. Other combined<unk><unk> s (those containing both an estrogen and a progestin) may also be used in an<unk>  or continuous<unk> . For example, the NuvaRing vaginal ring and the<unk>  patch have been studied for<unk><unk>  use, and the monthly combined injectable<unk>  may similarly eliminate bleeding.
