Common questions

Clarify some of the main doubts about the use of the contraceptive injection:

Do I need to go to the hospital for the contraceptive injection or can it be applied in pharmacies?

It must be administered by a health professional, but it is not mandatory to go to a hospital for the injection to be given by a doctor. It can be applied by the pharmacist himself, in the purchase of the medicine.

Does injectable contraception affect a woman’s fertility in the long run?

Injections temporarily interfere with a woman’s fertility, but should not make her infertile. However, it may take a little longer to get pregnant after giving up the injections, when compared to the pill.

In some women, it can take up to a year. This time, however, varies for each woman and is not associated with the time of use.

Should the reapplication of the injection be done according to the first day of the menstrual cycle?

No , reapplication does not happen according to the menstrual cycle, but according to the periodicity of the injection itself. If it is a monthly injection, it should be reapplied every 4 weeks, in the case of a quarterly injection, every 12 weeks.
