Currently, family planning is a very important issue for women and men, but especially for the former, and is that with women’s empowerment has come to the loss of many taboos and myths where the use of contraceptive methods was not very well seen.
Fortunately, that time has been left behind and nowadays talking about contraceptives encompasses not only the traditional options but also the new alternatives, or perhaps not so new but little known, among these are the contraceptive injections.
In the evolution of female contraceptive methods have been available options that have not been as effective, as contraceptive patches whose effectiveness and effectiveness rate was not so high, but what about the injections? No doubt they escape a little of the traditional barrier methods or intracorporeal devices.
What are the
It is an injection whose purpose is to avoid conception, through the basic mechanism of hormonal contraceptives: inhibiting ovulation, this is done from its composition of hormones, including progestin, which can go alone or combined estrogen.
How are contraceptive shots used?
You can start its use on any day of your menstrual cycle but you must use another contraceptive method in the days after its application, at least 7 days after that, so that the hormonal concentration reaches the desired levels, after those days the injection is safe
On the contrary, if you start the contraceptive cycle during the days of your menstruation, the injection will be effective almost immediately, this is because during menstruation there is no ovulation so the hormone levels at that time are similar to those induced by hormonal contraceptives
It must be administered within 3 months between each dose, as ovulation is inhibited there is no production of ovules that can be fertilized, so pregnancy does not occur.
The times between doses range from 12 to 16 weeks, the effectiveness of the injection is subject to these times, which you must be very strict when it comes to scheduling your medical appointment for your next dose. Taking into account the dosing interval, annually there are 4 vaccines, which provide protection close to 94-95% against pregnancy, the more punctual you are with the date the injection will be more effective.
