What is Junel?
Junel is a combined oral contraceptive (COC) that utilizes a blend of two female hormones: a progestin, norethindrone acetate, and an estrogen, ethinyl estradiol. These hormones work together to prevent pregnancy primarily by inhibiting ovulation (the release of an egg from the ovary). They also thicken cervical mucus, which makes it more difficult for sperm to reach an egg, and thin the uterine lining, hindering a fertilized egg from implanting.
Beyond contraception, Junel and its equivalents can be used to treat moderate acne and regulate menstrual cycles. The medication is available by prescription only and comes in different formulations, distinguished by dosage and the inclusion of an iron supplement.
Generic equivalents and other brand names
The generic name for Junel is simply norethindrone acetate and ethinyl estradiol. For versions containing the iron supplement, the generic name is norethindrone acetate, ethinyl estradiol, and ferrous fumarate.
There are dozens of other brands that contain the same active ingredients in identical or similar dosages. These generic or "branded generic" versions are therapeutically equivalent to Junel, meaning they work the same way in the body. Some common names include:

What the formulation differences mean
When you see names like Junel Fe 1/20 versus Junel 1/20, or Junel Fe 24, the differences are primarily in the dosage and the pack composition. Understanding these distinctions is important for ensuring you take your medication correctly.
Junel Fe vs. Junel
The "Fe" in the name stands for ferrous fumarate, which is a form of iron. A Junel Fe pack typically includes 21 active hormone pills and 7 inactive pills that contain iron. The iron serves no therapeutic purpose related to birth control but is a placebo to keep you in the habit of taking a pill every day. It may also help prevent anemia in individuals with heavier withdrawal bleeding. In contrast, a regular Junel pack contains only 21 active hormone pills, with no additional tablets for the seven-day break.
Junel 1/20 vs. Junel 1.5/30
The numbers in the name refer to the dosages of the active ingredients, norethindrone acetate and ethinyl estradiol, respectively, in each active pill.
- Junel 1/20 contains 1 mg of norethindrone acetate and 20 mcg of ethinyl estradiol. This is considered a lower-dose formulation.
- Junel 1.5/30 contains 1.5 mg of norethindrone acetate and 30 mcg of ethinyl estradiol. This is a slightly higher-dose formulation.
Junel Fe 24
Junel Fe 24 contains 24 active hormone pills (1 mg norethindrone acetate and 20 mcg ethinyl estradiol) and only 4 inactive iron pills. This regimen results in a shorter hormone-free interval and can lead to shorter or lighter withdrawal bleeding compared to 28-day packs.

Potential side effects
While Junel and its counterparts are generally safe and effective, they can cause side effects. Common adverse reactions include:
- Nausea and vomiting
- Headaches
- Breast tenderness
- Weight changes (often due to water retention)
- Irregular menstrual bleeding, particularly during the first few months of use
- Mood changes, including depression and anxiety
More serious, though less common, risks include blood clots, stroke, heart attack, and high blood pressure, especially for individuals over 35 who smoke. It's crucial to discuss all medical history and risk factors with a healthcare provider before starting any oral contraceptive.
How to switch from Junel to another brand
If you want to switch from Junel to a different brand with the same active ingredients, you should first consult your healthcare provider. They can confirm that the new medication is a suitable and therapeutically equivalent option for you. The process of switching is usually straightforward:
- Consult a doctor: Never switch birth control brands or formulations without medical guidance. While many are similar, slight differences in dosage or pack structure can impact effectiveness or side effects.
- Finish your current pack: It is typically recommended to finish the entire pack of your current birth control. This helps maintain your cycle and avoids confusion.
- Start the new pack: Begin the new brand on the day you would normally start your next pack. Follow the instructions for the new medication, as the number of active and inactive pills may differ.
Conclusion
Junel is one of many brand names for combined oral contraceptives containing norethindrone acetate and ethinyl estradiol. Understanding that medications like Larin Fe, Microgestin Fe, and Blisovi Fe are interchangeable equivalents is helpful for consumers and healthcare professionals alike. The key differences between formulations often relate to the dosage and the inclusion of non-hormonal iron tablets, denoted by "Fe." Always consult with a healthcare professional before changing birth control medications, even between formulations with the same active ingredients, to ensure continued safety and efficacy. For more information, the FDA provides detailed prescribing information on products like Junel.
