What are Ortho Micronor Birth Control Pills?

Ortho Micronor birth control pills are progestin-only birth control pills. They contain the progestin norethindrone which is used to prevent pregnancy. Because these pills do not contain any estrogen, they are also referred to as the mini-pill.

These birth control pills do not protect against sexually transmitted infections such as HIV/AIDs, herpes, chlamydia, etc. As such, it’s important to also use barrier methods such as the condom or female condom to limit the spread of infection.

Advantages of Using Ortho Micronor Birth Control Pills 

Because Ortho Micronor is a progestin-only pill, it is ideal for women who cannot take estrogen-based medications. Reasons for these may include having a history of or being prone to:

  • Blood clots in the legs or lungs
  • Heart disease
  • High blood pressure
  • Breast cancer
  • Migraines
  • Stroke

Progestin-only pills are also a better option for women who are obese, smokers, or over the age of 351.

Ortho Micronor: Breastfeeding

Ortho Micronor breastfeeding

Ortho Micronor is also a good option for breastfeeding mothers. Studies have shown that estrogen can interfere with lactation, which is why the combination pill and other estrogen-containing medications aren’t typically recommended by doctors. On the other hand, progestin-only pills have been found to have no detectable adverse impacts on breastfeeding2.

How do Ortho Micronor Birth Control Pills Work?

Ortho Micronor birth control pills work primarily by thickening the cervical mucus and changing the uterine lining to make it more difficult for a fertilized egg to attach3.

Ortho Micronor also suppresses ovulation (the release of an egg). However, this only occurs in half of the users.

Information about Ortho Micronor Dosage

Ortho Micronor dosage

Ortho Micronor birth control pills contain 0.35 mg of norethindrone. Because the dose of hormones is lower in comparison to the combination pill, there are 28 active pills in one pack. Thus, the Ortho Micronor dosage is one pill every day.

Unlike the combination pill, there are no breaks between packs. So, once you have finished the last pill in a pack, start a new one the next day.

Ortho Micronor: Missed Pill

It’s important to take Ortho Micronor birth control pills at the same time every day. According to VeryWell.com, this is because the progestin’s effect on cervical mucus last for about 24 hours.  If you miss the pill or are more than three hours late in taking it, your chances for getting pregnant increase.

In this event, take your missed pill as soon as you remember. You can then continue taking your pills at your regular time. You should also use backup contraception if you have sex in the next 48 hours.

Ortho Micronor Side Effects and Disadvantages

Unlike combination pills, the Ortho Micronor effectiveness rate is slightly lower. With perfect use, this pill is over 99% effective. However, with typical use, it’s about 92% effective, according to NHS. This is due to the potential of missing a pill or taking it late.

In addition to this, Ortho Micronor birth control pills are not always recommended for everyone. Women who have any of the following should not use this pill:

  • Unusual, undiagnosed vaginal bleeding
  • Breast cancer
  • Benign or cancerous liver tumours
  • Acute liver disease
  • Allergic reactions to norethindrone or other ingredients in this pill
  • A known or suspected pregnancy

Women who are taking certain medications for epilepsy, TB, or pulmonary hypertension and certain herbal products should also avoid this pill4.

Furthermore, Ortho Micronor may also increase your risk for the following:

  • Ectopic pregnancy
  • Ovarian cysts
  • Breast cancer
  • Cervical cancer
  • Liver tumours

Keep in mind that the chance of developing any of these conditions is very low. For the most part, the benefits of the pill outweigh the risks.

Additionally, even though this pill may be better suited for smokers, it is still advisable not to smoke while taking it.
