Your Sronyx 28 Day Prescription Can't Be Filled — Now What?

If your pharmacy just told you Sronyx 28 Day is unavailable, you're joining thousands of patients across the country dealing with the same problem. Mayne Pharma discontinued Sronyx in early 2025, and the supply has been fully depleted. For a full breakdown of what happened, see our post on why Sronyx is so hard to find in 2026.

The good news? Sronyx's active ingredients aren't unique. Several other birth control pills contain the exact same hormones at the exact same doses. Here's what you need to know about your alternatives.

What Is Sronyx 28 Day and How Does It Work?

Sronyx 28 Day is a monophasic combined oral contraceptive (COC) containing levonorgestrel 0.1 mg and ethinyl estradiol 0.02 mg. It comes in a 28-day pack with 21 active (white) tablets and 7 inactive (peach) placebo tablets.

The medication prevents pregnancy through three mechanisms:

• Suppressing ovulation — the primary way it works, by preventing the ovaries from releasing an egg each month
• Thickening cervical mucus — making it harder for sperm to reach and fertilize an egg
• Altering the uterine lining — reducing the likelihood of implantation if fertilization occurs

Sronyx is classified as a "low-dose" pill because it contains only 20 mcg of ethinyl estradiol, compared to the 30-35 mcg found in many other COCs. This lower estrogen content generally means fewer estrogen-related side effects. To learn more about how this medication works, see our detailed explainer on Sronyx's mechanism of action.

Direct Alternatives: Same Hormones, Same Doses

The following pills are therapeutically equivalent to Sronyx 28 Day. They contain levonorgestrel 0.1 mg and ethinyl estradiol 0.02 mg in the same monophasic 21/7 format. Switching between these should produce virtually identical effects.

Vienva

Vienva is one of the most commonly prescribed alternatives to Sronyx. It contains the exact same active ingredients at the same doses — levonorgestrel 0.1 mg and ethinyl estradiol 0.02 mg. It's a 28-day pack with 21 active tablets and 7 placebo tablets. Vienva is manufactured by Exeltis and is widely available at most pharmacies. Cash prices typically range from $15 to $50 per pack with a discount card.

Aubra

Aubra is another direct equivalent manufactured by Afaxys. Like Sronyx, it delivers the same low-dose hormone combination in a 28-day cycle. It has been on the market for several years and is well-established. Aubra is often available at both chain and independent pharmacies, with cash prices generally between $15 and $45 per pack with coupons.

Lutera

Lutera, made by Mayne Pharma (the same company that made Sronyx), contains levonorgestrel 0.1 mg and ethinyl estradiol 0.02 mg. It's one of the older and more established generics in this family. Cash prices are typically $20 to $60 per pack. Note that since both Sronyx and Lutera are from Mayne Pharma, availability of Lutera should be confirmed with your pharmacy.

Aviane

Aviane is one of the most widely prescribed low-dose oral contraceptives in the United States. It contains the same formulation as Sronyx and is manufactured by Teva Pharmaceuticals. Because of its popularity and wide distribution, Aviane is usually one of the easier alternatives to find in stock. Cash prices are usually $15 to $55 per pack with a discount card.

Other Options in the Same Class

If none of the direct equivalents above are available, your prescriber might consider other levonorgestrel/ethinyl estradiol formulations with slightly different doses:

• Levora / Altavera / Marlissa — levonorgestrel 0.15 mg / ethinyl estradiol 0.03 mg (slightly higher doses of both hormones)
• Trivora-28 — a triphasic pill with varying doses of levonorgestrel and ethinyl estradiol throughout the cycle
• Seasonique / Camrese — extended-cycle versions that reduce periods to four per year

These aren't identical to Sronyx, so discuss the differences with your healthcare provider before switching.

What to Know Before Switching

Switching between equivalent formulations (same active ingredients, same doses) is generally straightforward. Here are a few things to keep in mind:

• Inactive ingredients differ — the fillers, dyes, and binders in each brand are different. Most people won't notice any difference, but occasionally someone may react to a specific inactive ingredient.
• Start timing matters — if you're switching mid-pack, ask your prescriber whether to finish your current pack first or switch immediately.
• Breakthrough bleeding is possible — some women experience spotting when switching brands, even between equivalent formulations. This usually resolves within one to two cycles.
• Insurance coverage may vary — while most plans cover all generic COCs at $0 under the ACA mandate, your plan might have a preferred generic. Check with your insurer.

Final Thoughts

Sronyx 28 Day may be gone from pharmacy shelves, but its formula lives on in multiple other pills. Vienva, Aubra, Lutera, and Aviane all deliver the same levonorgestrel 0.1 mg / ethinyl estradiol 0.02 mg combination. Talk to your prescriber, update your prescription, and use Medfinder to find the alternative that's available near you.
