Monophasic contraceptive pills are currently one of the most popular methods of contraception. Single-phase pills are very easy to use, because when taking them, you do not have to divide the menstrual cycle into phases and remember the order in which you take the tablets. How do monophasic pills work? Who are they suitable for? How to use them? When to start taking them?
The two-component monophasic contraceptive pills are pills that contain two different female hormones in the same doses. As a result, you do not have to divide the menstrual cycle into phases and remember the order in which you take the tablets, as is the case with two- and three-phase contraceptive pills. In addition, of all the phase pills, they are the ones that have the least hormones.
Monophasic contraceptive pills - how do they work?
The package contains 21 combined contraceptive pills (preparations containing 24 tablets or 91 with an extended schedule are also available). Two-component pills are those that contain synthetic equivalents of two hormones - estrogen (ethinylestradiol) and progestogen (there are many synthetic equivalents of this hormone). All tablets contain the same amount of these two hormones.
Monophasic contraceptive pills have the same color and composition
Single-phase two-component contraceptive pills inhibit ovulation, i.e. ovulation and contribute to the thickening of the mucus in the cervix, thanks to which sperm cannot pass further. They also cause changes in the uterine mucosa, which makes it difficult for a fertilized egg to implant.

CHECK>>Low-dose contraceptive pills recommended for young women
Take the first tablet on the first day of the cycle, i.e. on the first day of menstruation. The packaging can also be started between the 2nd and 5th day of the cycle,however, in this case you should use an additional method of contraception (e.g. a condom) for the first 7 days of tablet-taking (in the first cycle). If a woman has already used combined pills (but two- or three-phase), the pack of monophasic contraceptive pills can be started the day after taking the last tablet of the previous pack of pills (without taking a break).

If the woman has previously taken a progestogen-only pill (the so-called mini-pill), she can be stopped each day and the monophasic tablets can be started at the same time the next day. At the same time, an additional method of contraception should be used for the first 7 days of taking the single-phase pills. If the woman has previously used a progestogen-only contraception such as injection or implant, the single-phase pill should be started on the day of the next injection or removal of the implant. In the case of preparations containing 21 pills, monophasic contraceptive pills should be taken every day, at the same time, for 21 days. Each pill is marked with the day of the week it should be taken. After 21 days, you should take a 7-day break in taking them, during which bleeding should occur (usually it is not profuse). This is a withdrawal bleeding known as "quiet menstruation". Take the first tablet of the next pack on day 8, even if bleeding is still ongoing. There are also single-phase contraceptive pills on the market with the 24 + 4 intake schedule (there are 28 pills in total in the package). Then they are taken every day at the same time for 28 days without taking breaks (however, the last 4 are placebo tablets, i.e. they do not contain hormones - they are taken only so that you do not forget about the next package). There are also single-phase contraceptives with the so-called extended application regimen. There are 91 tablets in total in the package - 84 pink, which are taken daily without interruption, and 7 white (placebo). One pack lasts for 3 months, and withdrawal bleeding does not occur until the end of this period. In total, the woman had 4 withdrawal bleedings a year. GOOD TO KNOW>>Contraception after.

According to an expertRafał Karwowski, a resident physician, specializing in obstetrics and gynecology
Since the introduction of contraception with the use of synthetic sex steroids, pharmaceutical companies have tried to minimize potential side effects while maintaining the full contraceptive effectiveness of pills. It was with this assumption that multiphase preparations (i.e. two-phase or three-phase tablets) were created. The multiphase regimen due to the lower dose of estrogens in the first days of the cycle was to be associated with a smaller number of side effects typical of the estrogen component, such as nausea. It was also supposed to reduce the total amount of hormones supplied to the woman's body. The studies did not show significant differences in the action of multiphase preparations in comparison with low-dose monophasic preparations. They also did not confirm any better, more beneficial effects resulting from their use. For this reason, multiphase preparations are very rarely used nowadays, and monophasic preparations occupy the first place on the oral contraceptive market.Monophasic contraceptive pills - when to start taking?
