About Provera and Norethindrone
Provera and Norethindrone are synthetic versions of the Progesterone hormone and can be prescribed for various reproductive issues. Despite both being synthetic progestins, they also serve different uses, highlighting the distinctions between Provera vs Norethindrone.
Provera is prescribed to treat abnormal uterine bleeding in non-pregnant women and to help restore regular menstrual periods in those experiencing Amenorrhea. It is also used with Estrogen in Hormone Replacement Therapy during Menopause and to lower the risk of Endometrial Hyperplasia.
On the contrary, while Norethisterone is primarily known for its ability to delay periods, it also serves other purposes, such as treating Endometriosis, a condition characterized by the growth of uterine tissue in other areas, causing pain and irregular menstruation. Norethindrone is also used to address irregular or abnormal periods and bleeding.
Additionally, it can help restore a normal menstrual cycle in women who have experienced a cessation of menstruation for at least 3 months, provided they are not pregnant or going through menopause.
Efficacy
Numerous studies have been conducted to confirm the effectiveness of both Provera and Norethindrone. In a 2007 study and another in 2019, Norethindrone was found to be more effective than combined oral contraceptive pills in delaying menstruation and preventing breakthrough bleeding.
Another study demonstrated Norethindrone’s effectiveness as a contraceptive, with only 4.8% of women experiencing side effects.
Provera has been shown to be effective as a contraceptive with minor side effects.
Side Effects
Though both Norethindrone and Provera are synthetic progestins, they have different side effects. Common side effects of Provera include dizziness, breast tenderness, changes in menstrual periods, vaginal itching, and rashes. In contrast, Norethindrone is typically associated with side effects such as hair loss, stomach pain, weight gain, and headache.
Interactions
Like every medication, both Provera and Norethindrone also interact with other drugs, potentially hampering their effectiveness. However, Norethindrone is known to interact with more medications than Provera, particularly those used to treat certain types of cancer, hypertension, and other heart disorders.

Both medications have their unique side effects, and their efficacy varies based on the intended purpose of treatment. It’s important for individuals to consult with their healthcare providers to determine the most appropriate treatment option based on their specific medical needs and circumstances.
