, marketed as Aygestin
, contains a type of hormone
identified as progesterone
, which is used to restore menstruation in women who have stopped having menstrual cycles or periods (also called amenorrhea). Norethindrone can also assist in treating endometriosis
, a malady wherein the lining of the uterus
or the endometrium
doesn't shed properly and attaches to the outside of the uterus or other areas such as the bowels or ovaries
. Furthermore, this drug can manage heavy and unusual uterine bleeding caused by an imbalance of your hormones
. Nevertheless, it should not be used to control fibroid-type or cancerous bleeding.
The recommended dose for abnormal uterine bleeding caused by hormonal imbalance or for restoring menstrual periods is 2.5 to 10 milligrams daily taken for five to ten days during the second half of the twenty-eight day cycle. Your period should begin three to seven days after you stop taking this medication.
As for endometriosis therapy, the advised beginning dose is five milligrams daily for fourteen days. Your doctor may increase your dose by 2.5 milligrams a day for fourteen days up to a maximum of fifteen milligrams a day depending on the severity of your condition. Norethindrone therapy may continue for six to nine months or until unbearable breakthrough bleeding happens.
Keep in mind that norethindrone can increase your risk for clot-related disorders. Consult your healthcare specialist promptly if you experience any of the symptoms listed in the side effects section of this drug review. Your doctor will probably give you a complete physical exam including examination of your breasts
and pelvic organs in order to rule out cancer
and other problems before you start taking norethindrone . You should also take a Pap test or cervical smear test as well.
Norethindrone can cause some degree of water retention, so if you have a medical condition that may become worse because of water retention—for example, asthma
, or epilepsy—you should report it to your doctor right away. Make sure to tell your physician if you experience unexplained or irregular vaginal bleeding while taking this medication as well.
Norethindrone has a tendency to cause women depression
. If you have a history of suffering depression in the past, consult your doctor promptly, especially if you think you might be having a relapse while undergoing norethindrone treatment. On that note, you will probably need to halt therapy. The long-term effects of this drug on the function of certain organs such as the uterus, liver
, adrenal glands
, ovaries, and pituitary glands
are currently unknown.
Be warned that norethindrone can also affect blood
sugar and cholesterol levels, so if you suffer from high cholesterol or diabetes
, your doctor will want to monitor your blood sugar and cholesterol levels while you're under norethindrone therapy. This medication may also mask the onset of menopause
. All the same, older women susceptible to menopause are still qualified to take norethindrone . Finally, if you are being tested for cancer, inform your doctor or lab technician that you are taking the medicine.
Norethindrone increases your risk for blood clots
, which can lead to stroke, vision problems, breathing problems, and phlebitis. If you experience any of the following symptoms, then you may be suffering from the onset of a clot-related disorder: weakness or numbness in an arm
, migraine, loss of vision or double vision, coughing or shortness of breath, warmth and redness in a leg vein, or pain with swelling
. You must stop taking this drug and consult your doctor promptly if any of the above side effects happen to you.
Other possible side effects from norethindrone usage include yellowing of the skin or eyes, weight increase or decrease, swelling, stopping of menstrual flow, skin discoloration, rash with or without itchy spots, nausea

I only take norethindrone once every three months for ten days to manage my menopause with my Vivelle patch. I do not like taking the provera AT ALL, but it is a necessary evil as unopposed estrogen has a high risk of uterine cancer. I feel crappy while I'm on it, I don't sleep, I do retain water. It puts you right into PMS mode. It also gave me such severe acne I had to go a dermatologist and start on Solodyn, an oral systemic antibiotic for acne! Ugh!!!! If it wasn't for all the horrible menopausal symptoms including the 50 hot flashes I was having a day, I would do away with all of it. I am considering having a hysterectomy so I do not have to continue taking the Norethindrone. I am only 46 and I feel great on the estrogen. The norethindrone is the bugger.
