Short term only: Noristerat is a contraceptive that is injected into the muscle of the buttock. The injection is usually given during the first one to five days of your monthly period. Noristerat will continuously release progestin into your bloodstream over a period of eight weeks (two months) Noristerat is a short term contraceptive and should only be used for two 8 week courses max. Use Depo Provera for longer.
