Progesterone is a prescription medication used to cause menstrual periods in women who are premenopausal but have stopped having periods due to low progesterone levels in their bodies. It is also used to prevent abnormal thickening of the lining of the uterus in women taking estrogen.

Progesterone belongs to a group of drugs called progestins, which work to bring menstruation by causing "withdrawal" bleeding when the medication is stopped. 

This medication comes in capsule form and is taken once a day, at bedtime for 10 or 12 continuous days per cycle, depending on the condition being treated.

Common side effects of progesterone include headaches, breast pain, and irregular vaginal bleeding or spotting.

Progesterone is a prescription medication used to cause menstruation in women with an absence of menstrual periods due to a decrease in progesterone. Progesterone is also used in combination with estrogen-containing medications in postmenopausal women with a uterus (womb) to reduce the risk of developing cancer of the uterus.

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

What you can do to lower your chances of getting a serious side effect with progesterone:

• Talk with your healthcare provider regularly about whether you should continue taking progesterone.
• See your healthcare provider right away if you get unusual vaginal bleeding while taking progesterone.
• Have a pelvic exam, breast exam, and mammogram (breast X-ray) every year unless your healthcare provider tells you something else. If members of your family have had breast cancer or if you have ever had breast lumps or an abnormal mammogram, you may need to have breast exams more often.
• If you have high blood pressure, high cholesterol (fat in the blood), diabetes, are overweight, or if you use tobacco, you may have higher chances for getting heart disease. Ask your healthcare provider for ways to lower your chances for getting heart disease.

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. Some medicines may affect how progesterone work. Progesterone may also affect how your other medicines work.

• Progestins with estrogens should not be used to prevent heart disease, heart attacks, strokes, or dementia.
• Using progestins with estrogens may increase your chance of getting heart attacks, strokes, breast cancer, and blood clots.
• Using progestins with estrogens may increase your chance of getting dementia, based on a study of women age 65 and older.
• You and your healthcare provider should talk regularly about whether you still need treatment with progesterone.

Do not start taking progesterone if you:

• Have unusual vaginal bleeding
• Currently have or have had certain cancers
  Estrogen plus progestin treatment may increase the chance of getting certain types of cancers, including cancer of the breast or uterus. If you have or have had cancer, talk with your healthcare provider about whether you should take progesterone.
• Had a stroke or heart attack
• Currently have or have had blood clots
• Currently have or have had liver problems
• Are allergic to progesterone or any of its ingredients
• Think you may be pregnant

Capsules

Do not start taking progesterone capsules if you are allergic to peanuts. THIS PRODUCT CONTAINS PEANUT OIL AND SHOULD NOT BE USED IF YOU ARE ALLERGIC TO PEANUTS.

Grapefruit and grapefruit juice may interact with progesterone and lead to potentially dangerous effects. Discuss the use of grapefruit products with your doctor.

Tell your healthcare provider:

• If you are pregnant or breastfeeding.
• About all of your medical problems. Your healthcare provider may need to check you more carefully if you have certain conditions, such as asthma (wheezing), epilepsy (seizures), diabetes, migraine, endometriosis, lupus, problems with your heart, liver, thyroid, or kidneys, or have high calcium levels in your blood.
• About all the medicines you take.

Progesterone should not be taken during pregnancy.

Researchers have theorized that having low progesterone levels before a miscarriage may play a role in causing miscarriage. Others suggest that low progesterone levels indicate the body is preparing to miscarry a pregnancy for reasons unknown. More research is needed to determine if progesterone supplements are beneficial.

If your doctor prescribes progesterone during pregnancy to prevent a miscarriage or other pregnancy complications, you should know that although the prescribing information indicates progesterone should not be used during pregnancy, some research suggests there may not be an increased risk to the fetus.

Discuss your concerns about progesterone use during pregnancy with your doctor.

Tell your doctor if you are breastfeeding or plan to breastfeed. The hormone in progesterone can pass into your breast milk.

• Progesterone are to be taken at bedtime as some women become very drowsy and/or dizzy after taking progesterone. In a few cases, symptoms may include blurred vision, difficulty speaking, difficulty with walking, and feeling abnormal. If you experience these symptoms, discuss them with your healthcare provider right away.

WARNING: CARDIOVASCULAR DISORDERS, BREAST CANCER and PROBABLE DEMENTIA FOR ESTROGEN PLUS PROGESTIN THERAPY

Cardiovascular Disorders and Probable Dementia

Estrogens plus progestin therapy should not be used for the prevention of cardiovascular disease or dementia.

The Women's Health Initiative (WHI) estrogen plus progestin substudy reported increased risks of deep vein thrombosis, pulmonary embolism, stroke and myocardial infarction in postmenopausal women (50 to 79 years of age) during 5.6 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg] combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo.

The WHI Memory Study (WHIMS) estrogen plus progestin ancillary study of the WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with daily CE (0.625 mg) combined with MPA (2.5 mg), relative to placebo. It is unknown whether this finding applies to younger postmenopausal women.

Breast Cancer

The WHI estrogen plus progestin substudy also demonstrated an increased risk of invasive breast cancer.

In the absence of comparable data, these risks should be assumed to be similar for other doses of CE and MPA, and other combinations and dosage forms of estrogens and progestins.

Progestins with estrogens should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.
