Yes. Micronor (norethindrone 0.35 mg) is a progestin-only birth control pill, and there are several important cautions to know:
- Take it at the same time every day. If you are 3 or more hours late, contraceptive protection may decrease; use a backup method such as condoms for the next 48 hours.
- Do not use Micronor if you are pregnant, have current or suspected breast cancer, unexplained vaginal bleeding, acute liver disease, or liver tumors.
- Irregular bleeding or spotting is common. Contact your healthcare provider for unusually heavy or prolonged bleeding or if your periods stop unexpectedly.
- Seek medical attention for severe lower abdominal or stomach pain, particularly if pregnancy is possible, because a pregnancy occurring while taking a progestin-only pill could be ectopic (outside the uterus).
- Some medicines can make Micronor less effective, including certain seizure medications such as phenytoin and carbamazepine, rifampin, and potentially St. John's wort. Tell your pharmacist or prescriber about everything you take.
- Micronordoes not protect against HIV or other sexually transmitted infections.
- Tell your healthcare provider if you have diabetes or develop new or severe migraine-type headaches while taking it.
If you think you may be pregnant while taking Micronor, contact your healthcare provider and take a pregnancy test as appropriate.
