A contraindication is a special circumstance, illness or condition in which you should not take a medicine or undergo a certain treatment because it could be harmful to the patient; sometimes it can be dangerous and life-threatening. When a procedure should not be combined with another procedure or when a medication cannot be taken with another medication, this is called a relative contraindication. Contraindications should be taken seriously because they are based on the relative clinical experience of health care providers or on the results of proven studies.

Hypersensitivity to any of the components of Noranelle, current or history of deep vein thrombosis and thromboembolism; adenomas or carcinomas of the liver, active liver disease until liver function returns to normal; known or suspected breast carcinoma or other known or suspected estrogen-dependent neoplasia; disorders of fat metabolism; thrombogenic rhythm disorders and thrombogenic valvulopathies; sickle cell anemia; diabetes with vascular involvement; undetected vaginal bleeding; known or suspected pregnancy; cerebrovascular or ischemic heart disease; uncontrolled hypertension; hereditary or acquired thrombophilias; headache with focal neurologic symptoms such as aura; pancreatitis associated with severe hypertriglyceridemia (current or history).
Reasons for immediate discontinuation of Noranelle: Occurrence of migraine headaches for the first time or more frequent occurrence of unusually severe headaches; acute visual, hearing, or speech disturbances; first symptoms of thrombophlebitis or thromboembolism (e.g., unusual pain or swelling in the legs, stabbing pain when breathing, or coughing for no apparent reason); feeling pain or tightness in the chest Six weeks before elective surgery or during prolonged periods of immobilization; development of jaundice (cholestasis), hepatitis, or generalized skin itching; increased frequency of epileptic seizures; significant increase in blood pressure; onset of severe clinical depression; severe upper abdominal pain or liver enlargement.
Pregnancy use: if pregnancy occurs during treatment with combined oral contraceptives (OCs), further use should be discontinued. There is no conclusive evidence that estrogen and progestin contained in OCs can harm a developing baby if conception occurs accidentally while taking OCs.
Use during lactation: Small amounts of contraceptive steroids and/or metabolites have been found in the milk of nursing mothers, and several side effects on the baby, including jaundice and breast enlargement, have been reported. Lactation can be affected by OCs because OCs can decrease the amount and change the composition of breast milk.
Use of OCs is usually not recommended until the nursing mother has completely weaned her baby.
