Progesterone capsules and dextroprogesterone tablets are not recommended to be taken at the same time; taking one alone is fine. Although these two medications have different ingredients, they are the same type of medication and play the same role in regulating the value of progesterone in the body. It treats diseases related to progesterone deficiency, such as dysfunctional uterine bleeding, amenorrhea, premenstrual tension syndrome, preeclampsia, habitual abortion, and infertility due to luteal insufficiency. Luteinizing hormone is a natural progestin secreted by the ovaries, and dydrogesterone is synthetic, and both drugs have the same pharmacological effects. If taken at the same time, due to the different active ingredients of these two drugs, there is no way to adjust the dosage, which will affect the efficacy of the treatment, but also increase the side effects on the body, so do not take at the same time. Before taking the two drugs, it is recommended to do a hormone test before using the drugs.
