There is information that shows that women who started to inject Depo-Provera immediately after birth may develop severe prolonged bleeding. As a consequence, in this period of time, the drug should be used cautiously. Patients who decide to use the medication immediately after childbirth or after an abortion should be informed about the possible risks of such a decision. In addition, it should be indicated that in non-breast-feeding mothers, ovulation can be observed already during the 4th week after the birth process.
Breastfeeding mothers can do the first injection at least 6 weeks after the birth of the child - during this period the infant's enzymatic system is developed more fully. Further procedures are performed at intervals of 12 weeks.
