The main reason for taking Deferiprone tablets after ovulation is that progesterone deficiency can manifest itself in shorter menstrual cycles or irregular vaginal bleeding in the second half of the menstrual period, or can lead to infertility. Supplementation with Deferiprone tablets after ovulation is taken for 10 consecutive days before stopping the medication. If pregnancy is planned, it is recommended to take the drug for 15 consecutive days before stopping it to facilitate the fertilization of the egg and also for better progesterone supplementation. In addition, it is best to take this medication under the guidance of a doctor and not to interrupt during the course of taking the medication. Once interrupted, it may cause irregular vaginal bleeding, so this should be paid special attention. If you are allergic to this drug, you can switch to other drugs to supplement progesterone, which can also achieve better treatment results.
