Norethisterone, a synthetic progestin hormone, is commonly used to delay menstruation for convenience or to alleviate symptoms of premenstrual syndrome (PMS). However, like any medication, it comes with potential side effects that should be carefully considered.
1. Breakthrough Bleeding and Spotting
One of the most common side effects of using norethisterone to delay period is breakthrough bleeding or spotting. This can occur as the uterine lining sheds prematurely due to the hormonal changes induced by the medication. The spotting may be light and intermittent or heavier, resembling a period.
2. Mood Changes
Norethisterone can affect hormone levels and neurotransmitter activity in the brain, leading to mood changes. Some users may experience irritability, anxiety, or depression while taking the medication, especially if they have a history of mood disorders.
3. Nausea and Gastrointestinal Symptoms
Norethisterone can cause nausea, vomiting, and other gastrointestinal symptoms, such as abdominal pain, diarrhea, or constipation. These side effects are generally mild and transient, but they can be uncomfortable for some individuals.
4. Headaches and Dizziness
Headaches and dizziness are other potential side effects of norethisterone. These symptoms may be related to the hormonal changes or to the medication’s effects on blood pressure.
5. Breast Tenderness and Engorgement
Some women may experience breast tenderness and engorgement while taking norethisterone. This is caused by the increased progesterone levels, which can stimulate breast tissue growth.
