Alternatives to Opill 28 Day if You Can't Fill Your Prescription

Opill (norgestrel 0.075 mg) is the first FDA-approved OTC birth control pill in the U.S., available since March 2024 without a prescription. While it's widely stocked at major pharmacies and retailers, individual stores may run out, or you may have reasons to consider a different option — including cost, insurance coverage, or a preference for a method with a different timing window or longer duration.

This guide covers the best alternatives to Opill 28 Day, how they compare, and what to discuss with your healthcare provider before switching.

Understanding What Makes Opill Unique

Before choosing an alternative, it helps to understand what Opill is and how it works. Opill is a progestin-only pill (POP), sometimes called a minipill. It contains 0.075 mg of norgestrel — a synthetic progestin — with no estrogen. Opill works primarily by thickening cervical mucus to prevent sperm from reaching the egg, thinning the endometrial lining, and in some cycles, partially suppressing ovulation.

Its key defining features are: no estrogen (making it safer for many who can't take estrogen), OTC availability (no prescription needed), 3-hour daily timing window, and all 28 tablets are active — there are no placebo days.

Alternative 1: Norethindrone (Errin, Camila, Heather, Nor-QD)

Norethindrone 0.35 mg is the most widely available prescription progestin-only pill in the United States. It's been on the market for decades and is available in generic form at virtually every pharmacy.

Requires a prescription (from a provider, clinic, or telehealth service)

Cost: $10–$30/month cash price; often $0 with insurance under the ACA

Same 3-hour daily timing window as Opill

Works primarily by thickening cervical mucus; suppresses ovulation in about 50% of cycles

Safe for breastfeeding, high blood pressure, migraine with aura, and cardiovascular risk factors

Best for: People who want an affordable pill option, are comfortable with the 3-hour timing window, and can access a prescription. Often $0 with insurance, making it cheaper than buying Opill OTC without coverage.

Alternative 2: Slynd (Drospirenone 4 mg)

Slynd is a prescription progestin-only pill that stands out for its 24-hour missed-pill window — far more forgiving than Opill's 3-hour window. Slynd primarily works by suppressing ovulation rather than thickening cervical mucus.

Requires a prescription

Cost: Generic drospirenone $30–$60/month; brand Slynd $150–$250/month without insurance

24-hour missed-pill flexibility (similar timing to combination pills)

Anti-androgenic properties — may help with hormonal acne or PCOS

28-pill pack: 24 active pills + 4 placebo days (may have a scheduled bleed)

Best for: People who want more timing flexibility with a progestin-only pill, or who benefit from anti-androgenic effects.

Alternative 3: Nexplanon (Etonogestrel Implant)

Nexplanon is a small progestin-releasing rod inserted under the skin of the upper arm. It's the most effective reversible contraceptive available — over 99% effective — and lasts up to 3 years. Because it delivers hormone continuously without daily pills, there's no timing window to worry about.

Requires an office visit for insertion and removal

Over 99% effective — not dependent on daily adherence

Lasts up to 3 years; fertility returns quickly after removal

Often $0 with insurance; significant upfront cost without insurance

Best for: People who want "set it and forget it" contraception and don't want to remember a daily pill.

Alternative 4: Hormonal IUD (Mirena, Liletta, Kyleena, Skyla)

Hormonal IUDs release a low dose of levonorgestrel (a progestin) directly in the uterus. They are highly effective, long-lasting (5–8 years depending on the brand), and provide localized hormone delivery — meaning systemic hormone levels remain very low.

Mirena and Liletta: Last up to 8 years; can also reduce heavy menstrual bleeding

Kyleena and Skyla: Smaller devices, lower hormone doses, last 5 years

Over 99% effective; not affected by drug interactions that reduce pill effectiveness

Office visit required for insertion and removal

Best for: People who want long-term, low-maintenance contraception — especially those on medications (like seizure drugs or rifampin) that reduce the effectiveness of oral contraceptives.

Alternative 5: Depo-Provera (Medroxyprogesterone Injection)

Depo-Provera is a progestin injection given every 3 months at a clinic or doctor's office. It works by suppressing ovulation and is highly effective when used on schedule. No daily pill required.

Office or clinic visit required every 3 months

Highly effective with typical use; can cause irregular bleeding or absence of periods

Fertility may take 6–18 months to return after stopping — important to consider if planning pregnancy soon
