What is Nortrel?
Nortrel is a brand name for a combination oral contraceptive pill (COC). This prescription medication contains a mix of two types of female hormones: a progestin (norethindrone) and an estrogen (ethinyl estradiol). The different forms of Nortrel, such as Nortrel 0.5/35, Nortrel 1/35, and Nortrel 7/7/7, refer to the specific dosage and hormone composition within each pill pack. For instance, the '1/35' in Nortrel 1/35 indicates 1 mg of norethindrone and 35 mcg of ethinyl estradiol in each active tablet. The formulation can be monophasic, where the dose of hormones remains constant, or triphasic, where the dose changes during the cycle to mimic a woman's natural hormone fluctuations.
Nortrel and its generic equivalents are widely used as a method of birth control. The use of this medication does not, however, protect against sexually transmitted diseases (STDs) like HIV. A healthcare provider's consultation is essential before starting this or any hormonal contraceptive to ensure it is the right and safest option for your health needs.
How Does Nortrel Work?
Nortrel prevents pregnancy through a three-pronged approach involving its hormonal components:
- Inhibition of Ovulation: The combination of estrogen and progestin suppresses the release of gonadotropins, which are hormones that trigger ovulation (the release of an egg from the ovary). By preventing the egg from being released, there is no egg to be fertilized.
- Thickening of Cervical Mucus: The hormones cause the mucus in the cervix to become thicker and stickier. This creates a barrier that makes it more difficult for sperm to travel into the uterus and reach any potential eggs.
- Alteration of the Uterine Lining: Nortrel also changes the lining of the uterus (the endometrium), making it thinner. This reduces the likelihood that a fertilized egg could successfully attach itself to the uterine wall and implant.
Uses and Benefits of Nortrel
While primarily used for contraception, Nortrel offers several non-contraceptive benefits that can improve a user's health.
Primary Use
- Preventing Pregnancy: When taken correctly and consistently, Nortrel is a highly effective method of preventing pregnancy.
Secondary Benefits
- Period Regulation: Many users experience more regular menstrual cycles, which can be beneficial for managing and predicting periods.
- Painful or Heavy Periods: Nortrel can decrease blood loss and alleviate painful periods (dysmenorrhea). For some, it can even be used to make periods optional by skipping the inactive pills and going directly to the next pack.
- Acne Treatment: The hormonal balance can help treat moderate acne in women over 15 who have started their menstrual cycle.
- Reduced Risk of Ovarian Cysts: Use of oral contraceptives can decrease the risk of developing ovarian cysts, especially in women with conditions like polycystic ovarian syndrome (PCOS).
- Management of PMDD and PMS: For some patients, a healthcare provider may prescribe Nortrel to help manage symptoms associated with premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD).
Potential Side Effects and Risks
As with all medications, Nortrel has potential side effects, with some being more common than others. It's crucial to be aware of the risks, especially serious ones.
Common Side Effects
- Nausea and vomiting
- Headaches
- Breast tenderness
- Bloating and fluid retention
- Mood changes or depression
- Vaginal spotting or breakthrough bleeding, particularly in the first few months
- Weight changes
Serious Risks
- Cardiovascular Events: A major warning is the increased risk of serious cardiovascular events, including blood clots, stroke, and heart attack, especially for women over 35 who smoke.
- High Blood Pressure: Some women may experience elevated blood pressure while on Nortrel.
- Liver Problems: In rare cases, liver issues such as benign hepatic adenomas or jaundice can occur.
- Blood Clots (Thromboembolism): The risk of developing deep vein thrombosis (DVT) or pulmonary embolism increases with hormonal contraceptives.
- Migraines: New or worsening migraine headaches may occur.
Types of Nortrel Pills
Nortrel is available in different formulations, each with a specific hormonal profile. The most common types are monophasic and triphasic versions:
- Monophasic (Nortrel 0.5/35 and 1/35): In these packs, all 21 active pills contain a constant, fixed dose of norethindrone and ethinyl estradiol. The pack typically includes 7 inactive (placebo) pills to keep the user on a daily routine, during which withdrawal bleeding occurs.
- Triphasic (Nortrel 7/7/7): This formulation uses color-coded tablets that change the dose of progestin in three stages during the menstrual cycle to more closely mimic the natural cycle. The pack contains 7 tablets with a low dose of norethindrone, 7 with a medium dose, and 7 with a high dose, followed by 7 inactive pills.
Comparison with Other Contraceptives
Understanding how Nortrel compares to other contraceptive methods can help in making an informed choice with a healthcare provider.

Who Should Not Take Nortrel?
Certain medical conditions or lifestyle factors can make Nortrel unsafe. It is crucial to discuss your complete health history with a doctor.
- Smokers over 35: Due to the significantly increased risk of serious cardiovascular events.
- History of Blood Clots: Women with a history of deep vein thrombosis, pulmonary embolism, stroke, or heart attack should not use Nortrel.
- Certain Cancers: A history of breast, uterine, or other hormone-sensitive cancers is a contraindication.
- Liver Disease: Severe liver disease or liver tumors prevent safe use of Nortrel.
- Uncontrolled High Blood Pressure: Women with hypertension not adequately managed should avoid combination pills.
- Migraine with Aura: Migraines accompanied by specific neurological symptoms increase stroke risk.
- Pregnancy: Nortrel should not be used during pregnancy.
How to Take Nortrel
For maximum effectiveness, Nortrel must be taken at the same time every day, no more than 24 hours apart. The exact regimen depends on the type of pill pack (21-day or 28-day) and whether you start on the first day of your period or the first Sunday following it.
- 28-day regimen: Take one active (hormone) pill daily for 21 days, followed by one inactive (placebo) pill daily for 7 days. Start a new pack the next day after the last inactive pill, regardless of whether your period has started or stopped.
- 21-day regimen: Take one active pill daily for 21 days, followed by 7 pill-free days. On the eighth day, start a new pack.
- Missed pills: Instructions vary depending on the week and number of pills missed. Always refer to the patient information leaflet or contact your healthcare provider for specific guidance. Using a backup birth control method, such as condoms, may be necessary.
It is highly recommended to read the Patient Information Leaflet that accompanies the medication for detailed instructions and precautions. For help remembering to take your pill, setting a daily alarm or using a mobile app can be effective strategies.
Conclusion
Nortrel is a prescription combination birth control pill containing norethindrone and ethinyl estradiol, used primarily to prevent pregnancy. It is also effective for managing menstrual symptoms and treating acne. The medication works by inhibiting ovulation, thickening cervical mucus, and changing the uterine lining. While generally safe for many, it carries serious risks, including blood clots, especially for women over 35 who smoke. The specific formulation of Nortrel, whether monophasic or triphasic, affects the hormone dosage throughout the cycle. Anyone considering starting Nortrel should have a thorough discussion with a healthcare provider to review their medical history, understand the potential benefits and risks, and determine if it is the most suitable contraceptive choice.
