Hailey Fe and Junel Fe contain the same active ingredients in the same doses, and both are generic versions of the brand-name pill Loestrin Fe. They are therapeutically equivalent, meaning the FDA considers them interchangeable for preventing pregnancy. The differences between them come down to the manufacturer, inactive ingredients, and in some cases the number of active pills per pack.
Same Hormones, Same Doses
Both Hailey Fe and Junel Fe use the same two hormones: norethindrone acetate (a progestin) and ethinyl estradiol (an estrogen). They’re available in matching strengths. The 1/20 version of each contains 1 mg of norethindrone acetate and 20 mcg of ethinyl estradiol per active pill. The 1.5/30 version contains 1.5 mg and 30 mcg, respectively.
The brown reminder pills in both brands contain 75 mg of ferrous fumarate, a form of iron. These aren’t hormonal pills. They exist to keep you in the habit of taking a pill every day, with the added benefit of a small iron supplement during the days you’d otherwise take nothing.
One Important Difference: Hailey 24 Fe
This is where things get slightly more complicated. Junel Fe follows a standard 21/7 schedule: 21 active hormone pills followed by 7 brown iron pills. The standard Hailey Fe 1/20 and Hailey Fe 1.5/30 follow that same 21/7 pattern.
However, there’s also a product called Hailey 24 Fe, which uses a 24/4 schedule: 24 active pills and only 4 iron pills. That’s three extra days of hormones per cycle, which means a shorter hormone-free window and typically a lighter, shorter withdrawal bleed. Hailey 24 Fe is not the same as Junel Fe, even though the per-pill hormone content is identical. The different schedule changes how the medication works in practice. If your pharmacy switches you from Junel Fe to Hailey 24 Fe (or vice versa), that’s a meaningful change worth discussing with your prescriber.
Inactive Ingredients Vary
Because Hailey Fe and Junel Fe are made by different manufacturers, their inactive ingredients are not identical. These are the fillers, binders, coatings, and dyes that hold the pill together and give it its color and shape. Hailey Fe’s active tablets, for example, use acacia, corn starch, lactose monohydrate, magnesium stearate, sucrose, and talc. Junel Fe’s inactive ingredient list overlaps but isn’t a perfect match.
For most people, this makes zero practical difference. But if you have a known sensitivity or allergy to a specific filler, like lactose, it’s worth checking the ingredient list for whichever version your pharmacy stocks. The full inactive ingredient list for any generic is available on the DailyMed database maintained by the National Library of Medicine.
Why Pharmacies Switch Between Them
If you’ve been taking Junel Fe and your pharmacy suddenly fills your prescription with Hailey Fe (or the other way around), it’s because both are approved generics of the same reference drug. Pharmacies routinely substitute one generic for another based on supply, pricing, and contracts with manufacturers. Your copay, the pill color, and the packaging may change, but the hormonal content stays the same.
That said, some people notice differences when switching between generics. These are usually minor, things like spotting for a cycle or a slight change in side effects. Whether this is due to the inactive ingredient differences or simply the body adjusting is debated, but the effect is real enough that some people prefer to stay on one specific generic. If that matters to you, your prescriber can write “dispense as written” for a particular manufacturer’s version, though this may affect your insurance coverage.
Matching the Right Versions
To make sure you’re comparing equivalent products, match the numbers after the name:
- Hailey Fe 1/20 and Junel Fe 1/20: Same 21/7 schedule, same low-dose hormones. These are direct equivalents.
- Hailey Fe 1.5/30 and Junel Fe 1.5/30: Same 21/7 schedule, same higher-dose hormones. Also direct equivalents.
- Hailey 24 Fe: Uses a 24/4 schedule. Not a direct substitute for any Junel Fe product, despite sharing the same per-pill hormone doses.
If your prescription simply says “Hailey Fe 1/20,” it’s functionally interchangeable with Junel Fe 1/20. If it says “Hailey 24 Fe,” it’s a different regimen and shouldn’t be swapped with Junel Fe without a new prescription.
