Safety basics
- Take doses eight hours apart. Phone alarms help.
- Use condoms if pregnancy prevention is a concern. At this dose and short duration, norethindrone is being used to delay your period, not as contraception.
- You shouldn't take norethindrone if you currently have or have had breast cancer in the past.
What is norethindrone?
Norethindrone is a synthetic progestogen (progestin) that has been used in medicine since the 1950s. It's one of the most widely studied hormonal medications available.
- At low doses (0.35 mg daily), norethindrone is prescribed as a progestin-only birth control pill, commonly known as the "mini-pill."
- At the higher dose used for period delay (5 mg three times daily), it works by maintaining progesterone levels that keep the uterine lining stable, preventing the hormone drop that triggers menstruation.
- Once you stop taking it, progesterone levels fall and your period begins within 2-4 days.
Who should avoid norethindrone?
Norethindrone is safe for most people, but certain conditions are contraindications. You should not take norethindrone if you have:
- Current or past breast cancer
- A history of blood clots (DVT or pulmonary embolism)
- Active liver disease or liver tumours
- Undiagnosed abnormal vaginal bleeding
- A known or suspected pregnancy
If any of these apply to you, tell the clinician during your intake. They'll decide if norethindrone is safe for you.
What if I miss a dose?
- Take the missed dose as soon as you remember.
- If it's close to your next scheduled dose, skip the missed one. Do not double up.
- Missing doses may cause breakthrough bleeding or spotting.
- Set phone alarms for every 8 hours to stay on track.
