Do you suffer from painful irregular periods? Normal periods are painful enough, but if you suffer from particularly painful or irregular periods or have endometriosis or another condition with these symptoms then you are likely to be on the lookout for help in the form of medication to alleviate or treat the symptoms of the disorder.
Looking to delay the start of your period? There are any number of reasons as to why you might want to delay your period. No time for painful cramps, bloating and mood swings. An important week at work? A holiday you just want to enjoy without the hassle of having your period. I’m sure you can come up with a hundred reasons, but is it possible? It is and there are several solutions, including getting a prescription for Norethisterone.
What is Norethisterone?
Norethisterone is a form of synthetic progesterone, similar to the progesterone women produce naturally in their bodies. The progesterone can help with hormone imbalance which can alleviate the symptoms of many menstrual problems. Norethisterone is the name of the active ‘progesterone’ ingredient.
Norethisterone is commonly known as the period delay pill. You start taking it 3 days before the start of your period and it can delay your period by up to 17 days. This can be useful for a special event or holiday. Your period will come 2 to 3 days after you stop taking it.
Norethisterone can also help with Pre-Menstrual Tension (PMT) and a variety of period disorders, or in the treatment of endometriosis and breast cancer. (see next section for further details)
