Micronor Birth Control is referred to as a ‘mini pill’ due to the fact it does not contain the hormone estrogen, only a progestin called Norethindrone. The efficacy of birth control pills during the first year is estimated at about a 9% failure rate. This is most likely due to missed or forgotten pills. Micronor Birth Control may be about 87-99.7% effective which is slightly less than the combination pills. During your first month taking Micronor Birth Control, it might be a good idea to use a second form of birth control until taking the pill daily is routine for you.
Micronor Birth Control suppresses ovulation so there is less chance for an egg to mature and be released for fertilization; it alters the consistency of your cervical mucus so it is thicker and makes it hard for sperm to make its way through your cervix; and could also thin your uterine lining so it is unable to support a fertilized egg. Micronor Birth Control can also help minimize period cramps and heavy bleeding.
If you suspect you are pregnant, stop taking Micronor Birth Control and see your doctor. Be prepared for the steps you have to take if you forget to take Micronor Birth Control or are late taking it. The benefit of Micronor Birth Control is that when you decide it is time to start a family, simply stop taking the pill. Unlike other contraceptive methods, you do not have to wait for the effects of the drug to wear off over a period of time as with some implants, injections, or patches.
Some women may have concerns about taking birth control with estrogen in case it causes interactions with other medications they take or if they are a smoker and are older than 35 years of age. If you have an increased risk or history of blood clots in your legs or lungs or other health problems that could be affected by estrogen, then ask your doctor about Micronor Birth Control with Norethindrone.
You should confirm that you are not pregnant before you start taking Micronor Birth Control. Talk to your doctor about other medical conditions or allergies you have and list any OTC or Rx drugs you take or use, including herbal remedies and dietary or vitamin supplements to determine if Micronor Birth Control is safe for you.
If you have never taken Micronor Birth Control before, you may be advised to use a non-hormonal back up contraceptive such as a condom for your first month so you are accustomed to taking Norethindrone at the same time on a daily basis. Micronor Birth Control will not protect you or your partner from sexually transmitted diseases including HIV.
