What is progesterone, and what is it used for?
Progesterone is a man-made medication derived from a plant source and is identical to the female hormone, progesterone produced in the ovaries. It promotes the development of the mammary glands, causes changes in the endometrium, which lines the uterus, relaxes uterine smooth muscles, blocks ovulation within the ovaries, and maintains pregnancy.
The synthetic version of progesterone is used to help regulate the uterine lining in post-menopausal women. Progesterone was approved in May, 1998.
What are the side effects of progesterone?
Side effects of progesterone are
- abdominal pain,
- breast tenderness,
- joint pain,
- mood swings, and
- hot flashes.
Progesterone is also associated with cardiovascular disorders, breast cancer, and possibly dementia in postmenopausal women.
What is the dosage for progesterone?
- Prevention of Endometrial Hyperplasia: 200 mg by mouth once daily at bedtime for 12 consecutive days per 28-day cycle.
- Treatment of Secondary Amenorrhea: 400 mg by mouth once daily at bedtime for 10 days.
Which drugs interact with progesterone?
Progesterone should be used with caution with ketoconazole (Nizoral), clarithromycin (Biaxin), and erythromycin (Ery-Tab) because they slow the breakdown of progesterone and increase its levels in the body.

Breast cancer is an invasive tumor that develops in the mammary gland. Breast cancer is detected via mammograms, breast self-examination (BSE), biopsy, and specialized testing on breast cancer tissue. Treatment of breast cancer may involve surgery, radiation, hormone therapy, chemotherapy, and targeted therapy. Breast cancer risk may be lowered by managing controllable risk factors. What you should know about breast cancer Breast cancer is the most common cancer among American women. One in every eight women in the United States develops breast cancer. There are many types of breast cancer that differ in their capability of spreading (metastasize) to other body tissues. The causes of breast cancer are unknown, although medical professionals have identified a number of risk factors. There are 11 common types of breast cancer and 4 uncommon types of breast cancer. Breast cancer early signs and symptoms include a lump in the breast or armpit, bloody nipple discharge, inverted nipple, orange-peel texture or dimpling of the breast's skin (peau d'orange), breast pain or sore nipple, swollen lymph nodes in the neck or armpit, and a change in the size or shape of the breast or nipple. Breast cancer can also be symptom free, which makes following national screening recommendations an important practice. Breast cancer is diagnosed during a physical exam, by a self-exam of the breasts, mammography, ultrasound testing, and biopsy. Treatment of breast cancer depends on the type of cancer and its stage (0-IV) and may involve surgery, radiation, or chemotherapy.
