This separation is performed on the basis of doses you are called for to take throughout your menstruation cycle. A monophasic tablet is a tablet which is composed of regular doses of both oestrogen and progestogen to be taken throughout. A biphasic supplement includes comparable doses of oestrogen, while the dose of progestogen modifications during your menstruation pattern. A triphasic pill is a supplement which once more has similar doses of oestrogen but various dosages of progestogen that you are needed to take.
