Contraindications for Norethindrone

Contraindications are specific conditions where a medication should not be used due to potential risks. If you have any of the following conditions, avoid taking Norethindrone. Always consult your healthcare provider before starting any new medication. If you have concerns, our telemedicine providers are available to assist you.

Pregnancy: Norethindrone is not recommended during pregnancy as it may affect the developing fetus. If you become pregnant while taking Norethindrone, stop the medication and contact your healthcare provider immediately.

Active or history of blood clots (thromboembolic disorders): Norethindrone may increase the risk of blood clots, particularly in individuals with a history of clotting disorders, such as deep vein thrombosis (DVT) or pulmonary embolism (PE).

Liver disease: Norethindrone is processed by the liver, and in individuals with liver disease, it may not be metabolized properly, leading to increased side effects or complications.

Breast cancer or other hormone-sensitive cancers: Norethindrone is a hormone-based medication and may stimulate the growth of hormone-sensitive cancers, such as breast or uterine cancer.

Undiagnosed abnormal vaginal bleeding: If you have unexplained vaginal bleeding, it’s important to get a proper diagnosis before starting Norethindrone, as the medication could mask symptoms of a more serious condition.

Drug to Drug Interactions

Norethindrone can interact with other medications, potentially reducing its effectiveness or increasing the risk of side effects. It is essential to inform your healthcare provider about all medications you are taking, including over-the-counter drugs and supplements. Below are some common medications that may interact with Norethindrone:

1. Rifampin (Rifadin): This antibiotic can decrease Norethindrone’s effectiveness by speeding up its breakdown in the liver.
2. Phenytoin (Dilantin): This anti-seizure medication can lower Norethindrone’s effectiveness by increasing its metabolism.
3. Carbamazepine (Tegretol): Another anti-seizure medication that can reduce Norethindrone’s effectiveness.
