Vestura is a generic version of Yaz. Both contain the same two active hormones in identical doses: 3 mg of drospirenone and 0.02 mg of ethinyl estradiol. They follow the same 24/4 pill schedule and are FDA-approved for the same uses. The key differences come down to price, manufacturer, and minor variations in inactive ingredients like fillers and dyes.
Same Active Ingredients, Same Doses
Yaz and Vestura each contain 24 active hormone pills and 4 inactive (placebo) pills per pack. Every active pill delivers exactly 3 mg of drospirenone, a synthetic progestin, and 0.02 mg (20 micrograms) of ethinyl estradiol, a synthetic estrogen. This is the same hormonal combination at the same strength. For the FDA to approve Vestura as a generic, the manufacturer had to demonstrate that it is bioequivalent to Yaz, meaning your body absorbs the hormones at the same rate and to the same extent.
You take one active pill at the same time each day for 24 consecutive days, then take one inactive pill daily for the remaining 4 days. This 24/4 cycle is shorter than the traditional 21/7 schedule used by many older birth control pills, which means fewer hormone-free days and a shorter, lighter withdrawal bleed for most people.
Approved Uses Are Identical
Because Vestura is a generic equivalent, it carries the same FDA-approved indications as Yaz. Both are approved as oral contraceptives, and both are also approved to treat two additional conditions: premenstrual dysphoric disorder (PMDD) and moderate acne in people who want birth control and are at least 14 years old.
The PMDD indication is notable because most birth control pills are not specifically approved for it. The 24/4 dosing schedule plays a role here. By shortening the hormone-free interval to just four days, the formulation reduces the hormonal fluctuations that can trigger severe premenstrual symptoms. Randomized, placebo-controlled trials using established symptom scales found significant improvements in mood, irritability, and physical symptoms like bloating and fluid retention. Improvements in acne and excess hair growth have also been documented in clinical research.
Where They Can Differ
The active hormones are identical, but the inactive ingredients (sometimes called fillers, binders, or excipients) can vary between brand-name and generic versions. In Yaz, the active tablets contain lactose monohydrate, corn starch, magnesium stearate, and a film coating made with hypromellose, talc, titanium dioxide, and a red iron oxide pigment. The white placebo tablets swap corn starch for microcrystalline cellulose and drop the red pigment.
Vestura’s inactive ingredient list may differ slightly. This matters in a few specific situations. If you have a known lactose intolerance that’s severe enough to react to the tiny amount in a pill, or if you have a rare allergy to a specific dye or filler, it’s worth comparing the full ingredient lists on the package inserts. For the vast majority of people, these differences have no effect on how the pill works or how you feel on it.
The pills may also look different. Yaz’s active tablets are light pink and debossed with “DS” inside a hexagon. Vestura’s tablets will have a different appearance and markings. This is purely cosmetic and required by law so that generics aren’t mistaken for brand-name products.
Cost and Insurance Coverage
The main practical reason Vestura exists is cost. Generic medications are typically much cheaper than their brand-name counterparts because the manufacturer doesn’t need to recoup the expense of the original clinical trials and development. Many insurance plans and pharmacy benefit managers will automatically substitute Vestura (or another generic equivalent like Nikki, Loryna, or Gianvi) when a prescription is written for Yaz, unless the prescriber specifically requests the brand name.
If your pharmacy switches you from Yaz to Vestura, or from one generic to another, the hormonal effect on your body should be the same. Some people report subjective differences when switching between generics, such as changes in breakthrough bleeding, mood, or skin. Whether this is due to the minor inactive ingredient differences, natural cycle variability, or a placebo effect is debated, but it’s a common enough experience that it’s worth noting. If you notice a meaningful change after a switch, you can ask your prescriber to specify a particular version on your prescription.
Other Generics in the Same Family
Vestura is not the only generic version of Yaz. Several others contain the same 3 mg drospirenone / 0.02 mg ethinyl estradiol formulation in a 24/4 regimen, including Nikki, Loryna, Gianvi, and Zarah. All are therapeutically equivalent to Yaz. Which one your pharmacy stocks depends on their supplier contracts, so you might be dispensed a different generic if you fill your prescription at a new pharmacy. Again, the active hormones are the same across all of them.
Yaz itself is related to, but distinct from, Yasmin. Yasmin uses the same progestin (drospirenone) but pairs it with a higher dose of ethinyl estradiol (0.03 mg instead of 0.02 mg) and follows a traditional 21/7 schedule. If your prescription says Yaz or Vestura, you should not be given Yasmin or its generics, as the hormone dose and cycle length are different.
