Progesterone injection is a type of female hormone given to replace the hormone progestin when the body is not making enough of it. In women who are not pregnant and have not gone through menopause, progesterone is used to restore normal menstrual periods that have stopped for several months (amenorrhea). Progesterone is also used to treat abnormal bleeding from the uterus that is due to low hormone levels and not other causes (e.g., fibroids, cancer of the uterus). Progesterone injection is available in generic form. Common side effects of progesterone injection include:
- pain and swelling at injection site,
- breast tenderness,
- weight gain or loss,
- increased body or facial hair,
- loss of scalp hair,
- drowsiness, or
Tell your doctor right away if you have serious side effects from progesterone injection including:
- unusual vaginal bleeding/discharge (e.g., breakthrough bleeding, spotting),
- stopped menstrual periods,
- breast lumps,
- swelling of the ankles or feet,
- mental/mood changes (e.g., depression, nervousness),
- dark patches on the skin or face,
- frequent or painful urination,
- dark urine,
- yellowing eyes or skin,
- stomach or abdominal pain, or
- persistent nausea and vomiting.
To treat amenorrhea, administer five to 10 mg for six to eight consecutive days. For functional uterine bleeding, administer five to 10 mg daily for six doses. If menstrual flow begins during the course of injections of progesterone, they are discontinued. Progesterone injection may interact with azole antifungals, rifamycins, St. John's wort, or anti-seizure medicines. Tell your doctor all medications and supplements you use. Progesterone injection is not recommended for use during pregnancy because it may harm a fetus, especially during the first 4 months of pregnancy. If you become pregnant or think you may be pregnant, tell your doctor. This drug passes into breast milk. Consult your doctor before breastfeeding.
